Answer:
Step-by-step explanation:
let y represent number of years...
9 ft tall = (12 * 9) = 108 inches
10 ft tall = (12 * 10) = 120 inches
Type A : 9 ft (or 108 inches) and grows 6 inches per year..
108 + 6y
Type B : 10 ft (or 120 inches) and grows 3 inches per yr
120 + 3y
how many years will it take them to be the same height...so when will they be equal....so set them equal and solve for y
108 + 6y = 120 + 3y
6y - 3y = 120 - 108
3y = 112
y = 112/3
y = 37 1/3 years....or 37 years and 4 months <====
check...
108 + 6(37 1/3) = 120 + 3(37 1/3)
108 + 6(112/3) = 120 + 3(112/3)
108 + 672/3 = 120 + 336/3
672/3 - 336/3 = 120 - 108
336/3 = 112
112 = 112 (correct)

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
