Answer:
Option B) 3.04
Step-by-step explanation:
We are given the following in the question:
Number of people interviewed,n = 163
Number of people hire, x = 121
Proportion of people hire =
Mean, μ = 3.3
Standard Deviation, σ = 0.4
We are given that the distribution of GPA for the successful interviewees is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.742
Calculation the value from standard normal z table, we have,
Thus, cut-off GPA should be 3.04.
Option B) 3.04
Here ya go! So let me walk you through it: first you need to get 1 to the other side. I said -1 because I placed it to the other side; since y=mx+b. So then you put in the slope intercept form. Btw sorry about the text lol..i wrote this in rough
Something is missing in this question because there are no dollars for the costs... Answer can not be determined.
Answer: 100 paintings
Step-by-step explanation:
To calculate the breakeven point, use the following formula:
= Fixed cost / Contribution margin
The Fixed cost is the one that does not change which is the $100 spent on brushes.
Contribution margin = Sales price - variable cost(cost that he incurs per painting)
= 10 - 9
= $1
Breakeven point = 100/1
= 100 paintings
