Answer:
5 1/4 cups
Step-by-step explanation:
Answer:
- s + m + L = 78
- 0.45s +0.60m +0.75L = 46.95
- s - m + L = 4
Step-by-step explanation:
The problem statement asks for the number of each size cup sold. You are told there are three sizes, so it is convenient to use one variable to represent the number of cups of a given size that were sold—three variables total.The problem statements tell you the relationships between the numbers:
- the total number of cups sold
- the total value of cups sold
- the relationship between numbers of one size versus other sizes
It is appropriate to write an equation for each of these relationships, for a total of three equations. (Here, the last of these equations is put into standard form to make it easier to translate this to a matrix equation for solving by calculator.)
___
The solution is: 20 small, 37 medium, and 21 large.
I’m pretty sure that it would be C because it’s the only one that has to do with students that eat lunch
<h3>
Answer: 72%</h3>
Explanation:
The phrasing "given that he or she is a graduate" means we focus on the middle row only. We ignore everything else.
We see that A = 1879 graduates receive financial aid out of B = 2610 graduates total.
This means the probability we want is therefore A/B = 1879/2610 = 0.7199 approximately. This converts to 71.99% and that rounds to 72%
