What is the annual compound interest rate for an investment account modeled by the function
y = 12 * 1.14t?
a.
0.14%
c.
14%
b.
12%
d.
114%

C. 14%

Step-by-step explanation:

We are given the function modeling the investment account as,

It is required to find the annual interest rate for the investment.

On simplifying the function, we have,

⇒

As, the general form for the compound interest is , where r is the interest rate.

On comparing we get,

The interest rate for the model is 0.14 i.e. 14%

Hence, option C i.e. 14% is correct.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
