Answer:
The cutoff sales level is 10.7436 millions of dollars
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
15th percentile:
X when Z has a pvalue of 0.15. So X when Z = -1.047.
The cutoff sales level is 10.7436 millions of dollars
Answer: $133.20
Step-by-step explanation: To simply find the sales tax all you have to do is:
Step 1 Multiply: 120 x .11 = 13.2
Step 2 Add: 120 + 13.2 = 132.2
So Robert actually has to pay $133.20
The answer is 7.084. Just multiply 3542 by .002 to find the answer.

First subtract the number that did, to find the number that didn't.
1300 - 520 = 780 customers did not order coffee.
Now divide the number who didn't order coffee by total number of customers:
780 / 1300 = 0.6
Multiply by 100 to get the percent:
0.6 x 100 = 60% did not order coffee.
