Answer:

Step-by-step explanation:
Given the expression

<u>Expand and simplify the expression</u>

Expand 4(2x + 7) = 8x + 28

Expand -3(x + 5) = -3x - 15

Group like terms

Add similar elements: 8x - 3x = 5x

Simplify

Therefore, we conclude that:

12 is the tital number of midfielders because since there are 3 people who make up 1/4 of the midfieldlers on the soccer team you need to miltiply 4 and 3 and 1/4 to count the total amount of midfeilders on the soccer team
(4)(3)=(1/4)(4)
The answer to 2y+7(y-3)=60 is y=9
Answer:

Standard error of mean = 689
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $28,520
Standard Deviation, σ = $5600
Mean of sampling distribution =

As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.
Sample size, n = 66
Since the sample size is large, we can use normal distribution for approximation.
Standard error of mean =

The answer you are looking for is B, there is a small chance of the event occurring. <span />
