Answer:
As per the statement:
Here, x represents the total sales in dollars
Total weekly pay of Alexa in dollar is represented by:
and
Total weekly pay of Samantha in dollar is represented by:
We have to find the value of x, in dollars that will make their weekly pay the same.
⇒
Substitute the values we have;

Subtract 250 from both sides we get;

Subtract 0.085 x from both sides we get;

Divide both sides by 0.01 we have;

Simplify:
x = $16300
Therefore, $16300 that will make their weekly pay the same
Answer:
the number of families needed for the survey is 2,157
Step-by-step explanation:
The computation of the number of families needed for the survey is shown below:
Given that
The Standard deviation is $900
Service level = 99%
z value at 99% = 2.58
Expenditures = $50
Based on the above information
The number of families needed for the survey is

= 2,157
Hence, the number of families needed for the survey is 2,157
The answer is: A) They are relatively prime. This is because both of them aren't divisible by any other number than 1. (or 0 if you really want to do that)
13.32 = 3/5
1/5 = 13.32 / 3
1/5 = 4.44
Full cost = 4.44 * 5
= 22.20
1. x=4, y=0
3. x=2.6666, y=0.3333
