Answer:
More than 30 dollars
Step-by-step explanation:
This situation can be described with the inequality:
x - 5 > 25
1. Add 5 to both sides
2. X > 30
5 times 325=5x-y should be the equation.
First, lets gather the information given in the problem :
Mr. G's total students = 57
Mr. G's band students = 25
Clue 1 : Since there are 25 students that take band, that means that there are 57-25 = 32 students who do not take band = 32 students who take choir or math or both.
Mr. G's band / choir / band and choir students = 48
Clue 2 : Since there are 25 students that take band and there are 48 that take either band / choir/ or both, that means we have 48-25 = 23 students who do not take band = 23 students who must take choir but not band. Thus
Mr. G's choir students = 23
So, we have the following :
Mr. G's total students = 57
Mr. G's band students = 25
Mr. G's choir students = 23
However, 25 + 23 = 48. Thus, we have 9 students not accounted for. These must be his math students. Hence,
Mr. G's total students = 57
Mr. G's band students = 25
Mr. G's choir students = 23
Mr. G's math students = 9
Next, they tell us that 9 students take both math and choir.
Without the vin diagrams, this is all I can provide.

The probability that a college student will get to work in 30 mins or less is 0.4 or 40%.
What does uniformly distributed probability mean?
Uniform distribution refers to a type of probability distribution in which all outcomes are equally likely to occur.
According to the given question:
Since the time is uniformly distributed, every possible travel time has the same likelihood of occurring.
Lower boundary (L) = 20 minutes
Upper boundary (U) = 45 minutes
The probability that a student finishes her trip in 30 minutes or less is:
P (t ≤ 30) = (30 - L)/(U - L)
= (30 - 20)/(45 - 20)
= 10/25
= 0.4 or 40%
The probability that she will get to work in 30 mins or less is 0.4 or 40%
