Kendrick opened a savings account and deposited $3,000.00 as principal. The account earns 6% interest, compounded quarterly. How much interest will he earn after 7 years?

$1551.67

Step-by-step explanation:

At Compound Interest, the Amount, A accrued by a Principal P for a period of t years compounded n times in a year at a rate of r is derived using the formula:

P=$3,000.00

r=6% = 0.06

n=4 (Since it is compounded quarterly)

t= 7 years

The Interest earned after 7 years will be:

Interest= Amount - Principal

          =4551.67 - 3000

          =$1551.67

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
