Could someone please help me I dont understand and I don't know what the answer is?

Step-by-step explanation:

If t is the number of years, then 12t is the number of months interest is compounded. The interest rate (growth rate) used each month is 1/12 of the annual rate, so is

  monthly growth rate = 2%/12 ≈ 0.167% = 0.00167

Then the monthly growth factor is ...

  monthly growth factor = (1 + monthly growth rate) = 1.00167

The overall account value is the initial value multiplied by this growth factor a number of times equal to the number of months, 12t. Repeated multiplication is indicated by an exponent:

  A = 1500(1.00167)^(12t) . . . . . . . matches the last choice

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
