Use the simple interest formula to find the ending balance. $5000 at 5% for 3.5 years. enter your answer in the box.

Ending balnace is; $5875

Step-by-step explanation:

Given: Principal(P) = $5,000 , Rate(R) = 5% and Time(T) = 3.5 years.

Using the simple interest(I) formula:

Substitute the given values in the formula to calculate interest(I);

Simplify:

To find the ending balance;

Ending balance is the net residual balance in an account.

Ending Balance = Principal + Interest

                          =

Therefore, the ending balance is, $5, 875

45

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
