what is rounding ?

Rounding is a mathematical process of approximating a number to a specified degree of accuracy. It involves replacing a number with a simpler, but close value that is easier to work with or understand.

In the given question,

The question asks us to find the annual premium for a $75,000 10-year term policy for a 25-year-old male, using the table of annual life insurance premiums per $1,000 of face value.

First, we need to find the premium per $1,000 face value for a 10-year term policy for a 25-year-old male. Looking at the table, we can see that the premium for a 10-year term policy for a 25-year-old male is $4.79 per $1,000 face value.

To find the annual premium for a $75,000 policy, we need to multiply the premium per $1,000 face value by 75. So:

Annual premium = $4.79 per $1,000 x 75 = $359.25

Rounding this answer to the nearest cent gives us:

$359.25 ≈ $359.26

Therefore, the annual premium for a $75,000 10-year term policy for a 25-year-old male is $359.26.

None of the answer choices match this result exactly, but the closest option is (a) $363.75, which is only off by a small amount due to rounding.

There are spiders and dogs in Veronica's backyard. Veronica sees 240 legs in total. The total number of animals (spiders and dogs) is 3 times the amount of spiders. How many spiders are in the backyard?

Answers

There are 15 spiders in the backyard. The correct option is D

To solve this problem

Let's begin by resolving the issue using algebra. Let's use "s" for the quantity of spiders and "d" for the quantity of dogs in the backyard.

As a result of the difficulty, we know that there are 3 times as many animals as there are spiders.

s + d = 3s

Simplifying this equation, we get:

d = 2s

We also know that there are 240 legs in the backyard, with each dog having 4  legs and each spider having 8. Thus, we can create the following equation:

8s + 4d = 240

Substituting d = 2s, we get:

8s + 4(2s) = 240

Simplifying and solving for s, we get:

16s = 240

s = 15

Therefore, there are 15 spiders in the backyard.

Answers

Answer:

The Probability that a marble selected at random from the bag will NOT be green is 1/3

Step-by-step explanation:

The probability of selecting a green bag

                                            = Total No.of green bags/ Total number of bags

                                           =8/12

Then the probability not of selecting a green bag  

                                                = 1 - The probability of selecting a green bag

                                                 = 1-(2/3)

A 50 miles
B 70 miles
C 140 miles
D 262.5 miles
(17.5 times 15)

Answers

Answer:

To solve this problem, we can use the concept of direct variation, which states that two quantities vary directly with each other if they can be expressed as y = kx, where y is the dependent variable, x is the independent variable, and k is a constant of variation.

In this case, the distance traveled is the dependent variable and the speed is the independent variable. We are given that the distance traveled is 17.5 miles when the time (or speed) is 15 minutes.

So, we can set up the proportion:

distance / time = constant

17.5 miles / 15 minutes = k

Solving for k, we get:

k = 17.5 / 15

k = 1.16667 (rounded to 5 decimal places)

Now that we have the constant of variation k, we can use it to find the distance traveled in 2 hours (which is equivalent to 2 hours * 60 minutes/hour = 120 minutes).

distance = k * time

distance = 1.16667 * 120

distance = 139.99964 miles (rounded to 5 decimal places)

So, the correct answer is C) 140 miles, as it is the closest rounded value to the calculated distance of 139.99964 miles.

How long would Reba have to take? How much would it cost?


If the job takes Reba ___hours, the cost would be ___$ with either artist.

HELPPP

Answers

If the job takes Reba 1 hours, the cost would be $ 19 with either artist

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let's assume the number of hours that Reba takes to paint the window is h. Then, the total cost of the job with Reba would be:

Total cost with Reba = $19 ( h )  + $41

The total cost with Pete is already given as a flat rate of $60.

We want to find the number of hours that Reba would have to take to charge the same amount as Pete, so we can set the two expressions for the total cost equal to each other and solve for "h":

$ 19 ( h ) + $ 41 = $ 60

Subtracting $41 from both sides, we get:

$ 19 ( h ) = $ 19

Dividing both sides by $ 19, we get:

h = 1

So Reba would have to take 1 hour to charge the same amount as Pete.

To calculate the cost of the job with either artist if it takes Reba 1 hour, we can substitute h=1 into the expression for the total cost with Reba:

Total cost with Reba = $ 19 ( 1 ) + $ 41 = $ 60

Hence , this is the same as the flat rate quoted by Pete, so the cost of the job would be $60 with either artist if it takes Reba 1 hour

The solution set of f(x) > 0 is x ∈ (-2, 8).

What is the set of the function?

To find the solution set of f(x) > 0, we need to first determine the critical values of x where f(x) changes sign.

Let's start by finding the domain of the function:

x² - 6x - 16 ≠ 0

We can solve for x by using the quadratic formula:

x = [6 ± √(6² + 4(16))]/2 = [6 ± √52]/2 = 3 ± √13

So the domain of f(x) is (-∞, 3 - √13) U (3 + √13, ∞).

Now let's factor the numerator and denominator of f(x):

f(x) = (x + 10)/[(x - 8)(x + 2)]

Express the statement as an inequality Part 5a^2

Answers

for the first one its x<0
the second one y>=0

Answer:

a) x < 0 excluding zero.

b) y ≥ 0

Step-by-step explanation:

a)

"x is negative": This means that x is less than zero. Negative numbers are any numbers less than zero, so this statement implies that x is a negative number. For example, x could be -1, -2, -3, and so on.

so answer is x < 0 excluding zero.

"x > 0": This means that x is greater than zero. Positive numbers are any numbers greater than zero, so this statement implies that x is a positive number. For example, x could be 1, 2, 3, and so on."x ≤ 0": This means that x is less than or equal to zero. Non-positive numbers are any numbers less than or equal to zero, so this statement implies that x could be zero or any negative number. For example, x could be -1, -2, -3, or 0."x < 0": This means that x is strictly less than zero. This statement implies that x is a negative number, but it does not include zero. For example, x could be -1, -2, -3, and so on, but not 0."X < 20": This means that x is less than 20. Any number less than 20 satisfies this statement, so x could be any negative number, zero, or any positive number less than 20."x = 0": This means that x is exactly equal to zero. The value of x is not positive or negative, but zero

The inequality that expresses the statement "x is less than 0" using the expression "5a^2" would be:

5a^2 > 0 and x < 0

Here, the expression "5a^2 > 0" means that the value of "5a^2" is positive for any non-zero value of "a". Therefore, the expression "5a^2 > 0" is true for all non-zero values of "a". The inequality "x < 0" means that "x" is negative, or less than zero.

So, combining the two expressions, we get the inequality:

5a^2 > 0 and x < 0

b)

The statement "y is nonnegative" means that y is greater than or equal to zero. Therefore, the valid options for y are:

"y ≥ 0": This means that y is greater than or equal to zero. Any non-negative number satisfies this statement, so y could be 0, 1, 2, and so on."y > 0": This means that y is strictly greater than zero. Any positive number satisfies this statement, so y could be 1, 2, and so on, but not 0."y ≤ 0": This means that y is less than or equal to zero. The only value that satisfies this statement is y = 0."y < 0": This means that y is strictly less than zero. No non-negative number satisfies this statement, so there are no valid options for y in this case."y = 0": This means that y is exactly equal to zero. This statement is true because zero is nonnegative.

Therefore, the valid option for y is y ≥ 0.

As the given statement "y is nonnegative" cannot be expressed as an inequality involving the expression "5a^2". The expression "5a^2" is a polynomial in the variable "a", and it is not related to the variable "y" in the statement.

The inequality that expresses the statements "x is less than 0" and "y is non-negative" using the expression "5a^2" would be:

5a^2 > 0 and y ≥ 0 and x < 0

Here, the expression "5a^2 > 0" means that the value of "5a^2" is positive for any non-zero value of "a". Therefore, the expression "5a^2 > 0" is true for all non-zero values of "a".

The inequality "y ≥ 0" means that "y" is non-negative, or greater than or equal to zero.

The inequality "x < 0" means that "x" is negative, or less than zero.

So, combining the three expressions, we get the inequality:

5a^2 > 0 and y ≥ 0 and x < 0

How many calories take a person in vegetables and carbohydrates?

The  number of calories a person  should consume from vegetables versus carbohydrates depends on various factors  such as age, gender, activity level, body composition, and overall health status. However, in general, it is recommended that a person on a  2000 calorie diet should  consume more calories from vegetables than from carbohydrates.

The United States Department of Agriculture (USDA) recommends  that adults consume 2.5 to 3 cups of vegetables per day, depending on their age, gender, and level  of physical activity. On a 2000 calorie diet, this would amount to approximately 200-300  calories from vegetables.

For carbohydrates, the recommended  intake varies depending on the individual's energy needs,  but it generally accounts for 45-65% of their total calorie intake. This  equates to 900-1300 calories from carbohydrates on a 2000 calorie diet.

Determine the measurement of DF.

DF = 1.58
DF = 1.52
DF = 1.1
DF = 5.5

Answers

We discard the negative solution, so EF = 8.725. Now we can substitute this value into the

How to solve the question?

To solve this problem, we can use the fact that if two triangles are similar, their corresponding sides are proportional.

We are given that triangle ABC is similar to triangle DEF. Therefore, we can set up the following proportion:

AB/DE = BC/EF = AC/DF

We are given the lengths of AB, AC, and BC, so we can substitute those values into the proportion:

11/DE = 7.9/EF = 7.6/DF

We are asked to find the length of DF, so we can isolate DF by cross-multiplying:

11EF = 7.9DE

7.6EF = 11DF

Now we can set the two expressions for EF equal to each other and solve for DF:

11EF = 7.9DE

11EF/7.9 = DE

1.39EF = DE

7.6EF = 11DF

DF = 7.6EF/11

Substitute the value of DE into the expression for EF:

DF = 7.6(1.39EF)/11

DF = 1.52EF

Now we need to find the value of EF. We can use the fact that the sum of the angles in a triangle is 180 degrees to find the measure of angle E:

angle E = 180 - angle D - angle F

We are not given the measures of angle D or angle F, so we cannot find angle E directly. However, we do know that triangles ABC and DEF are similar, so their corresponding angles are congruent. Therefore, we can use the measures of angles A, B, and C to find the measure of angle D:

angle D = angle A

angle D = 180 - angle B - angle C

Substitute the given values for angles A, B, and C:

angle D = 56.1 degrees

angle D = 116.9 degrees

We can use the Law of Cosines to find the length of EF:

EF²= DE² + DF²- 2(DE)(DF)cos(D)

EF²= 2.2² + (1.52EF)² - 2(2.2)(1.52EF)cos(D)

Substitute the two possible values for angle D:

EF²= 2.2²+ (1.52EF)² - 2(2.2)(1.52EF)cos(56.1)

EF²= 2.2²+ (1.52EF)² - 2(2.2)(1.52EF)cos(116.9)

Simplify both expressions:

EF²= 3.2596 + 2.3104EF²- 5.7024EF

EF²= 3.2596 + 2.3104EF² + 5.7024EF

Solve for EF using either equation:

-0.3104EF² + 5.7024EF - 3.2596 = 0

-0.3104EF² - 5.7024EF + 3.2596 = 0

Solve for EF using the quadratic formula:

EF = (-b ± √(b² - 4ac))/(2a)

EF = (-5.7024 ± √(5.7024² - 4(-0.3104)(-3.2596)))/(2(-0.3104))

EF = 8.725 or EF = -4.185

A restaurant raises the price of its signature dish by 15%
The new price of the dish is 14.50

What was the original price of the dish?

Answers

Answer:

Therefore, the original price of the dish was $12.61.

Step-by-step explanation:

Let the original price of the dish be "x".

After raising the price by 15%, the new price becomes:

x + 0.15x = 1.15x

We know that the new price is $14.50, so we can set up the equation:

1.15x = 14.5

To solve for x, we can divide both sides by 1.15:

x = 14.5 / 1.15

x = 12.61 (rounded to two decimal places)

Let's say that the original price of the signature dish was x.

The problem tells us that the price was increased by 15%, which means that the new price is 1.15 times the original price:

1.15x = 14.50

To find the original price, we need to isolate x on one side of the equation. We can do this by dividing both sides by 1.15:

x = 14.50 ÷ 1.15

x = 12.61

Therefore, the original price of the dish was $12.61.

what is polynomial?

A polynomial is made up of two terms, namely Poly (which means "many") and Nominal (which means "terms."). An expression that consists of variables, constants, and exponents and that is combined using mathematical operations such as addition, subtraction, multiplication, and division (no division operation by a variable) is referred to as a polynomial. The expression is divided into three categories: monomial, binomial, and trinomial depending on how many terms are included in it.

what are zeroes?

The zeros of a function are the values of its variables that meet the equation and result in the function's value being equal to 0. The zeros of a function can be represented graphically as the x-coordinates (or x-intercepts) where the graph intersects the x-axis. The discriminant formula allows us to identify whether the zeros of a quadratic function are real, complex, or repeating. As a result, when a function f(x) = 0, its zeros are x values. Therefore, if f(a) = 0, then 'a' is a zero of f(x).

A number cube with the numbers 1 through 6 is rolled. What is the probability of the number cube showing a 3 or an odd number?

Answers

There are three odd numbers on a number cube, which are 1, 3, and 5. Since 3 is already an odd number, we don't need to count it twice when finding the probability of rolling an odd number. So, there are a total of four numbers that meet the requirement of being a 3 or an odd number. That means the probability of rolling a 3 or an odd number is 4/6, or 2/3.

change.

Answers

The 90% confidence interval estimate of the population mean calories in a lunch box after the change is between 524.2 and 531.8.

How to construct a 90% confidence interval estimate of the population mean calories in a lunch box after the change.

(a) The point estimate of the population proportion of lunch boxes provided by "Better Lunch" had calories above 650 is 0.09, which is equal to 27/300.

(b) The sampling error at 98% confidence level for the estimate of the population proportion can be calculated using the following formula:

Sampling error = z*(standard deviation/square root of sample size)

Where z is the critical value at 98% confidence level, which can be found using a standard normal distribution table or calculator. For a 98% confidence level, the z value is 2.33.

Substituting the values, we get:

Sampling error = 2.33*(sqrt(0.09*0.91/300)) = 0.049 or 4.9%

Therefore, the sampling error at 98% confidence level for the estimate of the population proportion of lunch boxes provided by "Better Lunch" had calories above 650 is 4.9%.

(c) The 98% confidence interval estimate of the population proportion of lunch boxes provided by "Better Lunch" had calories above 650 can be calculated using the following formula:

Confidence interval = point estimate ± (z*standard error)

Where point estimate is 0.09, z is the critical value at 98% confidence level which is 2.33, and standard error is the standard deviation divided by the square root of sample size.

Substituting the values, we get:

Confidence interval = 0.09 ± (2.33*sqrt(0.09*0.91/300)) = 0.09 ± 0.114 or (0.026, 0.154)

Therefore, the 98% confidence interval estimate of the population proportion of lunch boxes provided by "Better Lunch" had calories above 650 is between 0.026 and 0.154.

(d) After the menu update, the sample mean of the calories of the above sample can be calculated as follows:

New sample mean = 0.96 * 550 = 528

The sample standard deviation after the change is still 40, assuming the variability of calories is not affected by the menu update.

To construct a 90% confidence interval estimate of the population mean calories in a lunch box after the change, we can use the following formula:

Confidence interval = sample mean ± (t*standard error)

Where t is the critical value at 90% confidence level with degrees of freedom (df) = sample size - 1. Using a t-distribution table or calculator with df = 299, we find that t = 1.645.

The standard error can be calculated as follows:

Standard error = standard deviation/sqrt(sample size) = 40/sqrt(300) = 2.31

Substituting the values, we get:

Confidence interval = 528 ± (1.645*2.31) = 528 ± 3.8 or (524.2, 531.8)

Therefore, the 90% confidence interval estimate of the population mean calories in a lunch box after the change is between 524.2 and 531.8.

Mrs. Jenkins gifts 10 cookies to her six sons if they share the cookies equally how many cookies should each son get

Answers

Mrs. Jenkins could divide each cookie into six equal pieces, giving each son six pieces of cookies, which would add up to 10 cookies in total.

How to solve the question?

If Mrs. Jenkins gifts 10 cookies to her six sons, the number of cookies each son should get can be found by dividing the total number of cookies by the number of sons.

So, if we divide 10 cookies equally among six sons, we get:

10 / 6 = 1.6667

This means that each son should get approximately 1.67 cookies. However, since it is not possible to divide a cookie into fractions, the actual number of cookies each son would get may vary.

To distribute the cookies equally, Mrs. Jenkins can either give each son one cookie and then divide the remaining four cookies equally among the six sons. This would give each son one cookie and each son would get an additional 4/6 or 0.67 cookies.

Alternatively, Mrs. Jenkins could divide each cookie into six equal pieces, giving each son six pieces of cookies, which would add up to 10 cookies in total.

In any case, the important thing is to ensure that each son receives an equal share of the cookies.
