Answer:
x=10 and y=15
Step-by-step explanation:
1: Plug y into the equation
y=2x-5
5x-4(2x-5)=-10
2: Solve for x
-3x=-30
<em><u>x=10</u></em>
3: Plug x into the other equation
x=10
y=2(10)-5
4: Solve for y
<u><em>y=15</em></u>

Answer: 0.48
Step-by-step explanation:
Let , Event A =Individuals earning more than $38,000.
Event B =Individual have a college degree
Given : The proportion of individuals in a certain city earning more than $38,000 per year :P(A)= 0.25.
The proportion of individuals earning more than $38 comma 00038,000 and having a college degree is P(A and B)= 0.12.
Using conditional probability formula , we have
i.e. Probability that an individual is a college graduate given that he is earning more than $38,000
Hence, the required probability = 0.48
