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

Answer:
$25 per hour
Step-by-step explanation:
Net pay= $1200
Deductions= $300
Hours worked= 60
Total pay=$1200+ $300= $1500.
Since her net pay is the money left after deductions, so we add the netpay and deductions to get her total pay.
Therefore, to find her hourly pay, we simply divide the total pay by the hours worked,so we have 1500/60= $25/hour
D because it can't be unique since many triangles can share these characteristics. It can't be more than one triangle and the triangle is possible.
30% , 3/5 , 0.8
Checking:
30%=30%
3/5=60%
0.8=80%
