Answer:
60 people
Step-by-step explanation:
Set up a proportion:
= 
Cross multiply and solve for x:
18x = 1080
x = 60
So, 60 people would have a gym membership
Answer:
x=2
Step-by-step explanation:
x + 4 = 3(3x - 4)
Distribute
x+4 = 9x -12
Subtract x from each side
x+4 -x = 9x-x-12
4 = 8x-12
Add 12 to each side
4+12 = 8x-12+12
16 = 8x
Divide by 8
16/8 = 8x/8
2 =x

10,000,000 + 1,000,000 + 700,000 + 60,000 + 800 + 20 + 5 = 11,760,825
Answer:
0.11
Step-by-step explanation:
Probability that house sale will increase = P(A) = 0.25
Probability that interest rate on house loans will go up = P(B) = 0.74
Probability that either house sales will go up or interest rates will go up = P(A or B ) = 0.89
We have to find the probability that neither house sales nor interest rates will increase. This event is the compliment of the event that either house sales will go up or interest rates will go up.
i.e.
Probability that neither house sales nor interest rates will increase = 

Using the value of P(A U B), we get:

The probability that neither house sales nor interest rates will increase during the next 6 months is 0.11
