Answer:
A)
B) $1200
Step-by-step explanation:
Let w represent employee's weekly sales and be total weekly earnings.
We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.
A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.
10% of weekly sales, w, would be
Therefore, the function models the employee's weekly earnings.
B) To find the weekly sales in the week, when employee earned $570, we will substitute in our formula and solve for w as:
Therefore, the amount of employee's weekly sales was $1200.

<u><em>Answer:</em></u>
<u><em>=28b-57</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
<h2><u>Lesson: Distributive property</u></h2>
Distributive property: a(b+c)=ab+ac
First, you expand or multiply by the numbers from left to right.
It change positive to negative sign.
Finally, you add/subtract by the numbers from left to right.
It change positive to negative sign.
<em><u>Final answer is 28b-57</u></em>
I hope this helps you!
Have a nice day! :)

Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
H0: µ = 7.2
For the alternative hypothesis,
H1: µ ≠ 7.2
This is a two tailed test.
Since the population standard deviation is given, the test statistic would be the z score determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 7.2
x = 7.3
σ = 0.8
n = 250
z = (7.3 - 7.2)/(0.8/√250) = 1.976
Test statistic is 1.976
