Henreys earnings over the past three weeks were $525, 575, and 475 what is his average earnings per week?

Answers

Answer 1

Answer: If you would like to know the average earning per week, you can calculate this using the following steps:

525 + 575 + 475 = 1575
1575 / 3 = 525

The correct result would be $525.

A yard is equal in length to three feet. The function f(x) takes a measurement in yards (as input) and returns a measurement in feet (as output).

Answers

Answer: Choice A

36.6

====================================

Work Shown:

f(x) = 3x

f(12.2) = 3*12.2

f(12.2) = 36.6

x is the length in yards, and f(x) is the length in feet.

12.2 yards = 36.6 feet

To convert from yards to feet, we multiply by 3. That explains how

1 yard = 3 feet
2 yards = 6 feet

Donner Summit, California, is a popular ski resort area. Over the past 60 years, the annual snowfall totals of Donner Summit have followed a distribution that is strongly skewed right with a mean of 404 inches and a standard deviation of 129 inches. If many samples of size 9 were taken, which of the following would best describe the shape of the sampling distribution of xbar

Answers

Answer:

This sampling distribution will only reflect the nature of its population distribution (strongly skewed right because the sample size of each sample, 9, is way less than the sample size of 30 required for the sampling distribution to be approximately normal) with mean 404 inches and standarddeviation of sampling distribution equal to 43 inches.

Step-by-step explanation:

The Central limit theorem explains that for an independent, any random set of sample taken from such a population distribution will have a distribution that is approximately normal (provided that the sample size is large enough) with the mean of sampling distribution also approximately equal to the population mean and the standard deviation of the sampling distribution is given as

σₓ = (σ/√n)

where

σ = population standard deviation

n = sample size

To work these out,

Mean of sampling distribution = population mean

μₓ = μ = 404 inches

Standard deviation of the sampling distribution = σₓ = (σ/√n)

σ = population standard deviation = 129 inches

n = sample size = 9

σₓ = (129/√9) = 43 inches.

For most databases, the 'large enough' criteria for the sampling distribution to be approximately normal is a sample size of about 30 and it gets closer as the sample size becomes larger.

The sample size in the question is 9 which is way less than 30, hence, this sampling distribution will only reflect the nature of its population distribution (strongly skewed right) with mean 404 inches and standarddeviation of sampling distribution equal to 43 inches.

Hope this Helps!!!

Answer:answer is D The shape is skewed right but less so than the population distribution.

Answers

Answer: Coefficient

Step-by-step explanation:

When solving for an unknown variable that has a number preceding it, you will divide both sides of the equation by this number, which is known as the coefficient.

A coefficient is a number preceding any variable in a function for example, given the function 4x, the variable is 'x' and the number preceding it is 4. This number preceding the variable is what we call 'coefficient' of the variable 'x'

During the year, FastDry Corporation has $ 340,000 in revenues, $ 155,000 in expenses, and $ 12,000 in dividend declarations and payments. Net income for the year was:

Answers

Answer:

$185,000

Step-by-step explanation:

We have been been given that during the year, Fast Dry Corporation has $ 340,000 in revenues, $ 155,000 in expenses, and $ 12,000 in dividend declarations and payments.

We will use following formula to solve our given problem.

$\text{Net income}=\text{Revenues}-\text{Expenses}$

$\text{Net income}=\$340,000-\$155,000$

$\text{Net income}=\$185,000$

Therefore, the net income for the year was $185,000.
