the lifetimes of batteries created by a company are normally distributed with a mean of 105 hours and a standard deviation of 12 hours. what percentage of these batteries will last between 90.6 and 109.8 hours? state your answer as a percent rounded to the nearest hundredth, but do not include a % symbol in your answer.

To find the mean, you add up all the numbers and then divide by the total number of numbers:

(99 + 66 + 94 + 100 + 54 + 57 + 74 + 91) / 8 = 731 / 8 = 91.375

So the mean is 91.375.

Hello and Greetings Brainly users.

This is an exercise in "Equation of the line that passes through two points". The equation of a line is a mathematical formula used to describe a straight line in a Cartesian plane.

To find the equation of a line that passes through two points, you must first calculate the slope using the formula: m = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the given points. Then, the point-slope form of the equation of the line is used to obtain the equation of the line: y - y₁ = m(x - x₁).

By solving this equation, we can obtain the equation of the line that passes through two points. If the slope of the line is zero, as in the case of two points lying on the same horizontal line, then the equation of the line is simply a horizontal line at y = k, where k is the y-coordinate of the points.

Applying the following formula:

m = (y₂ - y₁) / (x₂ - x₁)

where m is the slope of the line.

We find that the points are:

x₁ = 6 ,   y₁ = 4

x₂ = -5 , y₂ = 4

We substitute the data in the formula and solve:

m = (y₂ - y₁) / (x₂ - x₁)

m = (4 - 4)/(-5-6)

m = 0/-11

m = 0

Now, we can use the point-slope form of the equation of the line to obtain the equation of the line:

Where m = 0 and (x₁, y₁) is one of the two given points. We can choose any of the two points, but for this we will choose (6,4).

So, substituting the values we have, we have:

y - 4 = 0(x - 6)

Simplifying, we arrive at:

y - 4 = 0

y = 4

The equation of the line that passes through the points (6,4) and (-5,4) is y = 4 , since it is a horizontal straight line through the values of y = 4.

The question of which is better, a romance book or a storybook, is subjective and depends on individual preferences. But in my opinion, story book is better.

A romance book typically centers around a romantic relationship between two characters and is focused on emotional and personal development. In contrast, a storybook can cover a broad range of genres, including adventure, mystery, sci-fi, fantasy, etc. They can also have romance as a subplot but are not limited to it.

When it comes to the question of which is better, it ultimately depends on individual preferences. Romance books may be more appealing to readers who enjoy exploring the intricacies of relationships, while storybooks may be more suitable for those who prefer diverse storytelling.

In terms of how a storybook can be better than a romance book, one reason is the sheer variety of genres and styles that storybooks can offer. Readers who are looking for a thrilling adventure or a thought-provoking mystery may find a storybook more engaging than a romance novel, which often follows a similar formula.

Additionally, storybooks can introduce readers to new worlds, characters, and ideas, making them not just entertaining but also educational. This can provide a more enriching experience for readers, as they can learn and expand their knowledge while enjoying a good story.

Overall, the question of which is better, a romance book or a storybook, is subjective and depends on individual preferences. Both can offer unique and engaging experiences, and readers should choose the one that suits their tastes and interests.

Before doing calculations we can predict rectangular prism A has greater surface area to volume ratio than that of rectangular prism B.

The surface area of rectangular prism A is 136 square inches and that of B is 170 square inches. And  the ratio of surface area to volume of rectangular prism A is 1.4167 square inches/ cubic inches (approximately) and that of B is 1.1334 square inches/ cubic inches (approximately).

Rectangular prism A has dimension as,

length = 3 inches , breadth = 4 inches and height = 8 inches

Rectangular prism B has dimension as,

length = 5 inches , breadth = 5 inches and height = 6 inches

The surface area of rectangular prism can be calculated using the formula = 2( length*breadth + length*height + height*breadth)

Therefore, surface area of rectangular prism A = 2{ (3*4) + (3*8) + (4*8)} square inches =136 square inches (that is, 136 [tex]inches^{2}[/tex])

Surface area of rectangular prism B = 2{ (5*5) + (5*6) + (5*6)} square inches =170 square inches (that is, 170 [tex]inches^{2}[/tex])

The volume of rectangular prism can be calculated using the formula = length * breadth * height (in cubic unit)

Therefore, volume of rectangular prism A = (3)(4)(8) cubic inches =96 cubic inches (that is, 96 [tex]inches^{3}[/tex] )

Volume of rectangular prism B = (5)(5)(6) cubic inches =150 cubic inches (that is, 150 [tex]inches^{3}\\[/tex] )

Therefore, ratio of surface area to volume of rectangular prism A = (136/96) square inches/ cubic inches = 1.4167 square inches/ cubic inches (approximately)

Ratio of surface area to volume of rectangular prism B = (170/150) square inches/ cubic inches = 1.1334 square inches/ cubic inches (approximately)

Thus,  ratio of surface area to volume of rectangular prism A is greater than that of rectangular prism B.

We have shown that the boundary of a generalized rectangle is the union of finitely many closed generalized rectangles with volume zero.

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

Let A and B be two sets in a generalized rectangle R, i.e., R = A x B. The boundary of R, denoted by bd(R), is defined as the closure of the set of points that are not in the interior of R. In other words, bd(R) = cl(R) \ int(R), where cl(R) is the closure of R and int(R) is the interior of R.

To show that bd(R) is the union of finitely many closed generalized rectangles with volume zero, we first note that the closure of R can be expressed as the union of R and its boundary, i.e., cl(R) = R ∪ bd(R). Therefore, it suffices to show that R can be expressed as the union of finitely many closed generalized rectangles with volume zero and that bd(R) can also be expressed as the union of finitely many closed generalized rectangles with volume zero.

Let (a,b) be a point in R. Then there exists an open ball B((a,b), r) around (a,b) that is contained in R, where r > 0. Without loss of generality, we can assume that r is small enough so that B((a,b), r) is a generalized rectangle. Since B((a,b), r) is open, it follows that int(R) is the union of all such generalized rectangles. Therefore, R can be expressed as the union of finitely many closed generalized rectangles with volume zero, namely the closures of all such generalized rectangles.

Next, we show that bd(R) can be expressed as the union of finitely many closed generalized rectangles with volume zero. Let (a,b) be a point in bd(R). Then every open ball B((a,b), r) around (a,b) contains points both in R and in the complement of R. By definition of bd(R), the closure of B((a,b), r) intersects both R and the complement of R. Therefore, B((a,b), r) can be expressed as the union of two closed generalized rectangles, one contained in R and one contained in the complement of R. It follows that bd(R) can be expressed as the union of finitely many closed generalized rectangles with volume zero, namely the closures of all such balls B((a,b), r) and their decompositions into closed generalized rectangles.

Therefore, we have shown that the boundary of a generalized rectangle is the union of finitely many closed generalized rectangles with volume zero.

The mean of the data in the dot plot is approximately 5.33.

By dividing the sum of the numbers by the total number of numbers, the mean, or average, of the given numbers is determined. Mean is equal to (Sum of all Observations / Total Observations).

We must sum up all the values and divide by the total number of values to determine the mean of the data in the dot plot.

The first step is to count the dots for each value:

3 has 3 dots

4 has 5 dots

5 has 6 dots

6 has 8 dots

7 has 5 dots

8 has 3 dots

Then, multiplying each value by the quantity of dots associated with it, we must total up all the products:

(3 x 3) + (4 x 5) + (5 x 6) + (6 x 8) + (7 x 5) + (8 x 3) = 3 + 20 + 30 + 48 + 35 + 24 = 160

Last but not least, we must divide the entire number of values—i.e., dots—by the sum:

160 ÷ (3 + 5 + 6 + 8 + 5 + 3) = 160 ÷ 30 = 5.33

Yes, 90 degrees (clockwise) and -270 degrees (counterclockwise) are coterminal angles.

Two angles are coterminal if they share the same terminal side when drawn in standard position. In other words, coterminal angles differ by an integer multiple of 360 degrees.

To see if 90 degrees and -270 degrees are coterminal, we can add 360 degrees to the smaller angle (-270 degrees) and see if we get the other angle:

-270 + 360 = 90

Since we obtain 90 degrees after adding 360 degrees to -270 degrees, these two angles are coterminal. They share the same terminal side in standard position, even though their rotations have different directions (clockwise and counterclockwise).

The value of the unknown number -12.

Given that: twice a certain number is added to 10 and the result is minus 14.

Let's assume that the number we are trying to find is "x".

We can represent the statement twice this number (2x) is added to 10, and the result is -14 in an algebraic equation.

2x + 10 = -14

We can solve for x by isolating it on one side of the equation. We can start by subtracting 10 from both sides of the equation:

2x + 10 - 10  = -14 - 10

2x = -14 - 10

Simplifying the right side of the equation, we get:

2x = -24

Finally, we can solve for x by dividing both sides of the equation by 2:

2x/2 = -24/2

Rounding to the nearest minute, the athlete's trip will take approximately 96 minutes.

Let's start by drawing a diagram to better visualize the situation:

        A     x     D         C

        o-----x------------x

              |            |

              |            |

              |            |

              |            |

              |            |

              |            |

              B            |

              o------------o

Here, point A is where the athlete starts, point B is where she comes ashore due to the current, point C is her intended destination on the shoreline, and point D is the point where she switches from rowing to running.

From the diagram, we can see that the distance AB is 3 miles, and the distance AC is 3 + 1/2 = 3.5 miles.

We can use the Pythagorean theorem to find the distance BC:

[tex]BC^2 = AB^2 + AC^2[/tex]

[tex]BC^2 = 3^2 + 3.5^2[/tex]

[tex]BC^2 = 12.25[/tex]

BC = sqrt(12.25)

BC = 3.5

So the distance the athlete needs to travel on foot is 3.5 miles.

Let's first calculate the time it takes for her to row to point D:

Time to row to D = Distance / Speed

Time to row to D = 1/2 / 2

Time to row to D = 1/4 hours

Next, let's calculate the time it takes for her to run from D to C:

Time to run to C = Distance / Speed

Time to run to C = 3.5 / 4

Time to run to C = 7/8 hours

Now, we need to find the time it takes her to travel from B to C.

We can use the law of sines to find the angle between AB and BC:

sin(28) / 3 = sin([tex]\theta[/tex]) / 3.5

sin(theta) = 3.5 * sin(28) / 3

sin(theta) = 0.5407

theta = arc sin(0.5407)

theta = 33.15 degrees

Therefore, the angle between AB and BC is approximately 33.15 degrees.

We can use this angle and the distance BC to find the distance the athlete actually traveled from B to C:

Distance traveled from B to C = BC * sin([tex]\theta[/tex])

Distance traveled from B to C = 3.5 * sin(33.15)

Distance traveled from B to C = 1.925 miles

Finally, we can calculate the total time of the trip:

Total time = Time to row to D + Time to run to C + Time to travel from B to C

Total time = 1/4 + 7/8 + (1.925 / 4)

Total time = 0.25 + 0.875 + 0.48125

Total time = 1.60625 hours

To convert this to minutes, we can multiply by 60:

Total time = 1.60625 * 60

Total time = 96.375 minutes.

Step-by-step explanation:

The multiplicand is 22, the multiplier is 121 and the product is 2662.

The value of y for the inverse variation when x = -3 is derived to be equal to -8, and the equation that relating x and y is: y = 24/x.

Inverse variation is a mathematical relationship between two variables, in which an increase in one variable leads to a proportional decrease in the other variable. Mathematically, inverse variation can be expressed as y = k/x, where y and x are the two variables, k is a constant of proportionality, and the product of y and x is always equal to k.

when x = -4 and y = -6, then k is derived as:

-6 = k/-4

k = 24 {cross multiplication}

equation relating x and y is:

y = 24/x

when x = -3, y is derived as:

y = 24/-3

y = -8

Heidi's rate of elimination is also decreasing over time, but at a slower rate than Clara's which decreases exponentially over time

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

f(t) = 300(0.946)^t

For Clara, we can calculate the rate of elimination by finding the difference in the amount of medicine present between two consecutive time points, and dividing by the time elapsed:

From t=1 to t=2: f(2) - f(1) = 223.73 - 236.5 = -12.77 mg

Rate of elimination = -12.77 mg / (2-1) hours = -12.77 mg/hour

From t=2 to t=3: f(3) - f(2) = 211.65 - 223.73 = -12.08 mg

Rate of elimination = -12.08 mg / (3-2) hours = -12.08 mg/hour

From t=3 to t=4: f(4) - f(3) = 200.22 - 211.65 = -11.43 mg

Rate of elimination = -11.43 mg / (4-3) hours = -11.43 mg/hour

From t=4 to t=5: f(5) - f(4) = 189.41 - 200.22 = -10.81 mg

Rate of elimination = -10.81 mg / (5-4) hours = -10.81 mg/hour

Hence , this expression tells us that the rate of elimination for Heidi is proportional to the amount of medicine in her body at any given time, and decreases exponentially over time as the amount of medicine decreases

Answer: 1.2

Step-by-step explanation:

0.2 times 6 is 1.2

In this problem, we are given the angle A, and the side lengths a and b of triangle ABC. Using the   Geometry concept of Law of Sines, we can solve for the remaining angles and side lengths of the triangle. We find that sin(B) ≈ ∠B ≈ ° and ∠C ≈ °, and we can calculate that c ≈ 9.69. This gives us one possible triangle that satisfies the given conditions.

However, the problem states that there are two triangles that satisfy these conditions. To find the second triangle, we must first construct a triangle with angle A₁ = 180° - A and sides a₁ and b₁ such that a₁/b₁ = a/b. This is possible because the Law of Sines tells us that this ratio is constant for all three sides of a triangle. We then apply the Law of Sines to this new triangle to solve for its remaining parts. We find that sin(B₁) ≈ ∠B₁ ≈ ° and ∠C₁ ≈ °, and we can calculate that c₁ ≈ 12.02. This gives us the second possible triangle that satisfies the given conditions.

Now, to show that the areas of the two triangles are proportional to the sines of their respective angles C and C₁, we use the area formula for a triangle, which is 1/2 * base * height. The height of each triangle can be calculated using the sine of the angle opposite the base. Therefore, we have:

Area of ΔABC/ Area of ΔA₁B₁C₁ = (1/2 * a * c * sin(C)) / (1/2 * a₁ * c₁ * sin(C₁))

We can simplify this expression by substituting a1/b1 for a/b and simplifying:

Area of ΔABC/ Area of ΔA₁B₁C₁ = (a/b) * (c/c₁) * (sin(C)/sin(C₁))

Using the Law of Sines, we know that a/b = sin(A)/sin(B) and c/c₁ = sin(C)/sin(C₁), so we can substitute these values into our expression:

Area of ΔABC/ Area of ΔA₁B₁C₁ = (sin(A)/sin(B)) * (sin(C)/sin(C₁)) * (sin(C)/sin(C₁))

Using the fact that the angles in a triangle sum to 180°, we can solve for sin(A) and sin(B):

sin(A) = sin(180° - B - C) = sin(B + C)

sin(B) = sin(180° - A - C) = sin(A + C)

Substituting these values into our expression, we get:

Area of ΔABC/ Area of ΔA₁B₁C₁ = (sin(B + C)/sin(B)) * (sin(C)/sin(C₁)) * (sin(C)/sin(C₁))

Simplifying this expression, we get:

Area of ΔABC/ Area of ΔA₁B₁C₁ = sin(C)/sin(C₁)

Therefore, the areas of the two triangles are proportional to the sines of their respective angles C and C₁

The possible side lengths of rectangle B are 12 cm and 7 cm, or 9 cm and 5.25 cm, etc.

The side length of rectangle B is calculated as follows;

Side length of rectangle A = 6 cm and 3.5 cm

If the two rectangles are proportional, the possible side lengths of rectangle B is calculated as follows;

Length of B = 2 x 6 cm = 12 cm

Width of B = 2  x 3.5 cm = 7 cm

or

Length of B = 1.5 x 6 cm = 9 cm

Width of B =1.5  x 3.5 cm = 5.25 cm

Answer:

Step-by-step explanation:

In the equation h=6d, the independent variable is d, which represents the number of days. The dependent variable is h, which represents the height of the plant that depends on the number of days it has been growing.

The measurement that is closest to the lateral surface area of the cylinder is 132.15 square centimeters.

To determine the lateral surface area of a cylinder, you can use the formula 2πrh, where "r" represents the radius of the circular base of the cylinder, and "h" represents the height of the cylinder. This formula calculates the total area of the curved part of the cylinder, excluding the top and bottom circular bases.

The height of the cylinder is 5.8 cm and the radius of the circular base is 7.6/2 = 3.8 cm.

So, the lateral surface area of the cylinder is approximately:

2π(3.8)(5.8) ≈ 132.15 cm²

The value that is nearest to the lateral surface area of the cylinder is 132.15 square centimeters.

Retained earnings, December 31, 2018                               $6,470,000

Add: Net income December 31, 2019                                  $4,500,000

Less: Preferred stock dividends declared and paid           $4,500,000

Less: Common stock dividends declared and paid            $1,000,000

Total adjustments                                                                  $3,500,000

Retained earnings, December 31, 2019                             $9,970,000

The statement shows changes in the balance of retained earnings account during the year. The retained earnings balance at the beginning of the year is adjusted for the net income earned during the year and for the dividends declared and paid to the shareholders.

In this case:

So, total adjustments to the retained earnings balance:

= $4,500,000 + $1,000,000 - $4,500,000.

= $3,500,000

After adjustment on net income and dividends, the retained earnings balance at December 31 2019 is:

= $6,470,000 + $4,500,000 - $3,500,000

= $9,970,000

10% of 2-digit positive integers have a tens digit that is one greater than the ones digit.

To solve this problem, we first need to determine how many 2-digit positive integers there are. Since the smallest 2-digit integer is 10 and the largest is 99, we have a total of 90 integers (99-10+1).

Next, we need to determine how many of these integers have a tens digit that is one greater than the ones digit. To do this, we can create a chart and list out all possible combinations:

10, 21, 32, 43, 54, 65, 76, 87, 98

There are a total of 9 such integers. Therefore, the percentage of 2-digit positive integers that have a tens digit that is one greater than the ones digit is:

9/90 * 100% = 10%

So, 10% of 2-digit positive integers have a tens digit that is one greater than the ones digit.
To answer your question, let's first identify the range of 2-digit positive integers and determine the number of combinations where the tens digit is one greater than the ones digit.

The range of 2-digit positive integers is from 10 to 99. Now, we need to find the pairs of digits where the tens digit is one greater than the ones digit. The possible pairs are:

(1,0), (2,1), (3,2), (4,3), (5,4), (6,5), (7,6), (8,7), and (9,8)

There are 9 pairs that meet the condition. Now we need to find the total number of 2-digit positive integers:

99 (the last 2-digit integer) - 10 (the first 2-digit integer) + 1 = 90

So, there are 90 two-digit positive integers in total.

Now, we can calculate the percentage of the 2-digit positive integers that have a tens digit one greater than the ones digit:

(9 / 90) * 100 = 10%

Therefore, 10% of 2-digit positive integers have a tens digit that is one greater than the ones digit.

Approximately 4.44% of 2-digit positive integers have a tens digit that is one greater than the ones digit.

Let's consider the possible pairs of tens digit and ones digit that satisfy the condition. There are 4 such pairs: [tex](1, 0)$, $(2, 1)$, $(3, 2)$[/tex], and [tex](4, 3)$.[/tex] For each tens digit, there is exactly one ones digit that satisfies the condition. So, out of the 90 possible two-digit positive integers (ranging from 10 to 99), only 4 of them have a tens digit that is one greater than the ones digit.

Therefore, the percentage of 2-digit positive integers that have a tens digit that is one greater than the ones digit is:

[tex]$\frac{4}{90} \cdot 100% \approx 4.44%$[/tex]

So, approximately 4.44% of 2-digit positive integers have a tens digit that is one greater than the ones digit.
