According to the US Bureau of Labor Statistics publication News, self-employed persons with home-based businesses work a mean of
worty [1.4K]

Answer:

The answer is below

Step-by-step explanation:

Given that mean (μ) = 23 hours, standard deviation (σ) = 10 hours

a) The population is a group of self employed home based workers while the variable is the number of hours worked per week.

b) The mean of the distribution of sample means (also known as the Expected value of M) is equal to the population mean μ.

\mu_x=\mu=23\ hours

The standard deviation of the distribution of sample means is called the Standard Error of M, it is given by:

\sigma_x=\sigma/\sqrt{n} =\frac{10}{\sqrt{100} }=1

c) \mu_x=\mu=23\ hours

\sigma_x=\sigma/\sqrt{n} =\frac{10}{\sqrt{1000} }=0.32

d) The sample size has no effect on the mean, hence increasing the sample size does not change the mean.

The square root of sample size is inversely proportional to the standard deviation therefore increasing the sample size reduces the standard deviation.

Algebra help please?
spin [16.1K]

Answer is 3 seconds


When the bullet reaches the ground, ground being x in graph (and here its s which is  = 0)

s = -16t^2 + 48t

s = 0, solve for t

0 = -16t^2 + 48t

0 = t ( -16t + 48)

0 = 16t ( - t + 3)

now you have two equation

0 = 16t and 0 = -t +3 ( you can look at the graph line touches x twice)


0 = 16 t

0 = t ( you know its false, because time = 0)


You are left with

0 = -t + 3

t = 3


It takes 3 seconds for the bullet to return to the ground.

// Hope this helps.

Find the common factor and rewrite. Type your answer in the box. Do not use any spaces.
finlep [7]

Common factor is 4X

Rewriting the term we get: 4X(Y + 2Z)

Step-by-step explanation:

We need to find the common factor of the expression: 4XY + 8XZ

A common factor is the term that is common in all the terms of the expression.

In the given expression the common factor is: 4X because it is common in both terms

4XY + 8XZ

=4X(Y + 2Z)

So, Common factor is 4X

Rewriting the term we get: 4X(Y + 2Z)
