Answer: b. $1545
Find the amount of interest: for the time period, use 9/12 months, which equals 3/4, or 0.75; multiply: $1500 x 0.04 x 0.75 =$45. Add to find the amount paid back: $1500 + $45 = $1545

Mr. Gardener's annual interest rate is 8%.
40,000/500,000 = 0.08
0.75n + 2 = t
The passenger is charged $0.75 per/for a number of miles(n) plus a fee of $2, and the total cost of the ride is t.
Answer:
The probability of 1 or less children from that group to learn how to swim before 6 years of age is 0.072
Step-by-step explanation:
In this case we need to compute the probability of none of these 12 children learns to swim before 6 years of age. This is given by:
p(0) = (1 - 0.312)^(12) = 0.688^(12) = 0.01124
We now need to calculate the probability that one child learns to swim before 6 years of age.
p(1) = 12*0.312*(1 - 0.312)^(11) = 3.744*(0.688)^(11)
p(1) = 3.744*0.01634
p(1) = 0.0612
The probability of 1 or less children from that group to learn how to swim before 6 years of age is:
p = p(0) + p(1) = 0.01124 + 0.0612 = 0.07244
0.7(3s+4)-1.1s=7.9 equals s=5.1
