A+b = 5
b+c= 3 1/2
2 times 2 + 3 = 7
a times d =8
c+c = 1
(e)2 = 1/9
Answer:
Elimination
Step-by-step explanation:
You would not do substitution since it would not work so you do elimination since the 4y and -4y eliminate then you just solve for it.
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:-19
Step-by-step explanation:
3x+5-(2x-3)=0
3x+5-2x+3=0
x+8=0
x=-8
substitute x into 3x+5 to find the length of MO
3x+5
3(-8)+5
-24+5
-19
So, we’re looking for the amount of money Tom needs to spend to get his free meal.
X + 30.25 >
X > 9.75
X is the additional amount that Tom needs to spend. You subtract 30.25 on both sides in order to solve for x.
So, your answer would be at least $19.75
