The formula to find the LSA of a cylinder is 2πrh
Answer:
its red
0y225
Step-by-step explanation:
Answer:
a) 0.194
b) $440.8
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $9.40
Standard Deviation, σ = $4.40
Formula:
Standard error due to sampling =
a) P(tips from 40 parties > $400)
Thus, the average pay is
P(x > 10)
Calculation the value from standard normal z table, we have,
b) We have to find the value of x such that the probability is 0.01
Calculation the value from standard normal z table, we have,
Thus, the mean tip is $11.02
Tip for 40 parties =
Thus, he earns $440.8 on the best 1% of such weekends.
