Answer:

Step-by-step explanation:
We are given the following information in the question:
Percentage of of the diners who make reservations don't show up = 3%
Number of reservations = 83
Thus, we are given a binomial distribution with n = 83 and p = 0.97


Around 81 people can be expected to show up.

The standard deviation of this distribution is 1.56
9(x + 3) + 15x
9x + 27 + 15x ...combine like terms
24x + 27 <==
