vampirchik [111]

Step-by-step explanation:

Todd fills 30 paper cups with ketchup and Yuki fills 27 paper cups with ketchup.

Each paper cup holds 1 ounce

Todd = 30 * 1 = 30 ounces

Yuki = 27 * 1 = 27 ounces

Total ounces = 30 + 27

Later, Todd and Yuki learn that two other company employees completed exactly the same task.

Total ounces = 2 (30 + 27)

2/3x=10 help please and explain

stira [4]

Solutions

Simplify 2/3x to 2x/3

2x/3=10

2) Multiply both sides by 3

2x=10×3

3) Simplify 10×3 to 30

2x=30

4) Divide both sides by 2

x=30 ÷ 2

5) Simplify 30 ÷ 2 to 15

x=15

Answer = 15

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.
