Answer:
standard deviation is a quantity calculated to indicate the extent of deviation for a group as a whole.
Residual analysis is used to assess the appropriateness of a linear regression model by defining residuals and examining the residual plot graphs.

Answer:
Option E is correct.
The expected number of meals expected to be served on Wednesday in week 5 = 74.2
Step-by-step Explanation:
We will use the data from the four weeks to obtain the fraction of total days that number of meals served at lunch on a Wednesday take and then subsequently check the expected number of meals served at lunch the next Wednesday.
Week
Day 1 2 3 4 | Total
Sunday 40 35 39 43 | 157
Monday 54 55 51 59 | 219
Tuesday 61 60 65 64 | 250
Wednesday 72 77 78 69 | 296
Thursday 89 80 81 79 | 329
Friday 91 90 99 95 | 375
Saturday 80 82 81 83 | 326
Total number of meals served at lunch over the 4 weeks = (157+219+250+296+329+375+326) = 1952
Total number of meals served at lunch on Wednesdays over the 4 weeks = 296
Fraction of total number of meals served at lunch over four weeks that were served on Wednesdays = (296/1952) = 0.1516393443
Total number of meals expected to be served in week 5 = 490
Number of meals expected to be served on Wednesday in week 5 = 0.1516393443 × 490 = 74.3
Checking the options,
74.3 ≈ 74.2
Hence, the expected number of meals expected to be served on Wednesday in week 5 = 74.2
Hope this Helps!!!
Answer:A=x(x-4)-0.5(6)(x-4)-2(7)
Step-by-step explanation:
A=x(x-4)-(0.5(6)(x-4) + 2(7))
A=x(x-4)-0.5(6)(x-4)-2(7)
F(x) = 20000 (1-0.15) power x
So
f(x) = 20000 (0.85) power x
Answer
That should be it!
