Answer:

[tex](-4)\left(\frac{1}{3}\right)^{n-1}[/tex]

Step-by-step explanation:

The common ratio between any two terms in a geometric sequence is constant. Let this ratio be denoted by r. Then, we have:

[tex]r = \frac{\frac{4}{3}}{-4} = \frac{-\frac{4}{9}}{\frac{4}{3}} = \frac{\frac{4}{27}}{-\frac{4}{9}} = \frac{1}{3}[/tex]

Using this value of r, we can write the formula for the nth term an as:

[tex]an=[/tex][tex](-4)\left(\frac{1}{3}\right)^{n-1}[/tex]

To save on shipping costs, Camile should choose a box that is lightweight and has a small volume.

This is because she has realized that she is charged based on the volume of the box and not the weight.

Therefore, a smaller volume box would cost her less than a larger volume box of the same weight.

For example, if Camile needs to ship a 5-pound item, she should choose a smaller box with a volume that is just enough to fit the item, rather than a larger box with more empty space. This is because the larger box would have a greater volume, and therefore, incur a higher shipping cost even though it weighs the same as the smaller box.

In summary, when selecting a box to save on shipping costs, it is important to consider both weight and volume. Camile should choose a box that is lightweight and has a smaller volume to reduce her shipping costs.

Answer:

The mathematical property demonstrated by the statement 3 + (-6) = -6 + 3 is the commutative property of addition.

This states that: A + B = B + A

The commutative property of addition is the property that is demonstrated by the formula "3 + (-6) = -6 + 3".

This characteristic states that the sum is unaffected by the sequence in which two numbers are added. In other words, a + b = b + a for any two numbers a and b.

In this instance, the left side has 3 + (-6) which equals -3. We have -6 + 3 on the right side, which also equals -3. This indicates that the result is unaffected by the sequence in which the numbers are added.

We can thus write:

3 + (-6) = -6 + 3

-3 = -3

This demonstrates the truth of the assertion and serves as an illustration of the commutative property of addition.

The survey found that 86% of 2006 US students in grades 10-12 agreed with the statement "if I make a mistake, I try to figure out where I went wrong." The survey's margin of error is +/- 3.7%, so we can be 95% confident the true proportion falls between 82.3% and 89.7%.

This means that we can be 95% confident that the true proportion of students who agree with the statement lies between 82.3% and 89.7%. This interval is calculated as follows

Subtract the margin of error from the sample proportion to get the lower bound: 86% - 3.7% = 82.3%

Add the margin of error to the sample proportion to get the upper bound: 86% + 3.7% = 89.7%

Answer:

Step A: The third quartile is 9.5, choice d.

Step B: The median of the data set is 6.5.

Step C: The IQR of the data set is 6, and we found this value by subtracting the first quartile from the third quartile (9.5 - 3.5 = 6).

Step-by-step explanation:

First, let's analyze the data set.

1 2 3 4 5 6 7 8 9 10 11 12

Since this data set is already sorted in numerical order, we can determine the median by finding the middle value that divides the data set in half. With 12 values in the data set, the median would be between the 6th and 7th numbers, so we can find this by using the calculation (6+7)/2 = 6.5.

                 6.5

{1 2 3 4 5 6} | {7 8 9 10 11 12}

With this median, we split our data set into two halves. Now, we can find the first quartile, or the 25th percentile, by finding the median of the first half. This would be the value between 3 and 4, so (3+4)/2 = 3.5.

       3.5        6.5

{1 2 3} | {4 5 6} | {7 8 9 10 11 12}

We can repeat this step in the second half in order to find the third quartile or the 75th percentile. The median of the second half would be between 9 and 10, so (9+10)/2 = 9.5.

       3.5         6.5        9.5

{1 2 3} | {4 5 6} | {7 8 9} | {10 11 12}

Now we know Q1 (first quartile) and Q3 (third quartile), we can find the IQR which is Q3 - Q1, so Q3 - Q1 = 9.5 - 3.5 = 6.

So now we can answer the question:

Step A: The third quartile is 9.5, choice d.

Step B: The median of the data set is 6.5.

Step C: The IQR of the data set is 6, and we found this value by subtracting the first quartile from the third quartile (9.5 - 3.5 = 6).

Answer:

B

Step-by-step explanation:

The overall mean number of hours worked can be determined by calculating the weighted average of the means for males and females, taking into account the sample size as weights.

Given:

X₁ = 6 (mean number of hours worked for males)

X₂ = 9 (mean number of hours worked for females)

n₁ = 30 (sample size for males)

n₂ = 20 (sample size for females)

The overall mean number of hours worked, denoted as X, can be calculated as follows:

X = (X₁ * n₁ + X₂ * n₂) / (n₁ + n₂)

Plugging in the given values:

X = (6 * 30 + 9 * 20) / (30 + 20)

X = (180 + 180) / 50

X = 360 / 50

X = 7.2

In the event of shortening the standard error of mean to 15 we have to increase the size to 400. Therefore, the correct answer is Option B.

The  given standard error of the mean for a sample of 100 is 30. So to cut the standard error of the mean to 15, we have to proceed by increasing the sample size to 400.

The  formula for evaluating the standard error of mean
SEM = SD / √(n)
here, SEM = standard error of the mean,
SD = standard deviation
n = sample size
Staging the values
15 = SD / √(100)
15 x √(100) = SD
SD = 150
Now evaluating for the value of n
15 = 150 / √(n)
15 x √(n) = 150
√(n) = 10
n = 100
Now looking at the formula, we need to decrease SEM by half,

So we proceed by increasing the  sample size by a factor of 4.

In the event of shortening the standard error of mean to 15 we have to increase the size to 400. Therefore, the correct answer is Option B.

Answer:

152.4 centimeters.

Step-by-step explanation:

1 inch = 2.54 centimeters

60 inches = x centimeters

Where x is the number of centimeters equivalent to 60 inches.

To solve for x, we can set up a proportion:

1 inch / 2.54 centimeters = 60 inches / x centimeters

Cross-multiplying, we get:

1 inch * x centimeters = 2.54 centimeters * 60 inches

Simplifying, we get:

x = (2.54 cm/in) * (60 in)

x = 152.4 cm

Therefore, 60 inches is equivalent to 152.4 centimeters.

Answer:

The surface area (SA) formula for a rectangular prism is:

SA = 2lw + 2lh + 2wh

where l is the length, w is the width, and h is the height.

For the cereal box object given, we have:

l = 12 inches

w = 8 inches

h = 1.75 inches

So, substituting these values into the formula, we get:

SA = 2(12)(8) + 2(12)(1.75) + 2(8)(1.75)

SA = 192 + 42 + 28

SA = 262 square inches

Therefore, the surface area of the rectangular prism cereal box is 262 square inches.

Step-by-step explanation:

The SURFACE AREA OF THE RECTANGULAR PRISM is 262 in²

SURFACE AREA (S.A) OF RECTANGULAR PRISM= 2lw+2lh+2wh

LENGTH=12 inches

WIDTH= 8 inches

HEIGHT=1.75 inches



Applying the formula

We get

S.A=2*(12*8)+2*(12*1.75)+2*9(8*1.75)

S.A = 192+42+28 sq inches

S.A= 262 sq inches

Since this is a right triangle, let's use the Pythagorean Theorem.

Recall that the Pythagorean Theorem is:

[tex]a^2+b^2=c^2[/tex]

Where a is the length of one of the legs, b is the length of the other leg, and c is the length of the hypotenuse.

We are given the hypotenuse (15 m) and one of the legs (9 m).

Let's assign some values:

[tex]a=??\\c=15\\b=9[/tex]

Let's solve for b by using the Pythagorean Theorem.

[tex]a^2+b^2=c^2=\\a^2+9^2=15^2=\\a^2+81=225=\\a^2=144=\\a=12[/tex]

So, the length of the missing leg, a, is 12 m.

Answer:

The length of the missing leg is 12 m.

Step-by-step explanation:

SOLUTION :

Here we have given that the base of triangle is 9 m and hypotenuse is 15 m. We have to find the the height of triangle.

Using Pythagoras Theorem to find the height of triangle :

[tex]\quad{\longrightarrow{\sf{{(H)}^{2} = {(b)}^{2} + {(h)}^{2}}}}[/tex]

Substituting all the given values in the formula to find the height of triangle :

[tex]\quad{\longrightarrow{\sf{{(H)}^{2} = {(b)}^{2} + {(h)}^{2}}}}[/tex]

[tex]\quad{\longrightarrow{\sf{{(15)}^{2} = {(9)}^{2} + {(h)}^{2}}}}[/tex]

[tex]\quad{\longrightarrow{\sf{{(15 \times 15)} = {(9 \times 9)} + {(h)}^{2}}}}[/tex]

[tex]\quad{\longrightarrow{\sf{{(225)} = {(81)} + {(h)}^{2}}}}[/tex]

[tex]\quad{\longrightarrow{\sf{{(h)}^{2} = 225 - 81}}}[/tex]

What is fraction?

A fraction represents a part of a whole, and it is written in the form of one integer written above another, separated by a horizontal line. The integer on top is called the numerator, and the integer on the bottom is called the denominator.

The numerator represents the number of parts being considered, while the denominator represents the total number of equal parts that make up the whole. For example, the fraction 3/4 represents three parts out of a total of four equal parts.

Fractions can be used to represent values that are not whole numbers, such as halves, thirds, quarters, etc. They are commonly used in everyday life, such as when measuring ingredients in cooking, dividing up a pizza or a cake, or expressing a probability.

To find the amount of granola in the bowl, we need to subtract the total amount of yogurt and blueberries from the total volume of the bowl.

First, let's add up the yogurt and blueberries:

7/8 cup Greek yogurt + 1 1/4 cup blueberries

= 7/8 + 5/4 (we need to find a common denominator)

= 14/16 + 20/16

= 34/16

Next, let's convert the total volume of the bowl to a fraction with a common denominator of 16:

3 1/2 = 7/2 = 56/16

Now we can find the amount of granola:

Amount of granola = Total volume of bowl - Amount of yogurt - Amount of blueberries

= 56/16 - 34/16
