Use the simple interest formula.

You deposit $650 in a savings account. How long does it take an account with an annual interest rate of 5% to earn $178.25 in interest? Round your answer to the nearest tenth.

Answers

Answer:

The Answer is 5.5, rounded to the nearest tenth

Step-by-step explanation:

650 x .05 = 32.5

178.25 ÷ 32.5 = 5.48461538462

5.48461538462 rounds to 5.5

It will take 5 years and 6 months to earn $178.25 in interest.

What is the simple interest?

Simple interest is the borrowing amount added only to the principal amount.

The Formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100,

Where S.I. is simple interest, P is principal amount, T is time period and R is interest rate in a year.

Given:

You deposit $650 in a savings account with an annual interest rate of 5% to earn $178.25 in interest.

That means,

178.25 = 650 x 5 x t/100

t = 17825/3250

t = 5.5

Therefore, it will take 5 years and 6 months.

Suppose that a box of 86 circuits is sent to a manufacturing plant. Of the 86 circuits shipped, 5 are defective. The plant manager receiving the circuits randomly selects 2, without replacement, and tests them. If both circuits work, the manager will accept the shipment. Otherwise the shipment is rejected. What is the probability that the shipment is accepted

Answers

Answer:

the probability that the shipment is accepted is 0.8865

Step-by-step explanation:

Given the data in the question;

N = 86,  n/d = 5 and n = 2

now, without replacement

the probability that the shipment is accepted will be;

probability that the shipment is accepted = probability that non is defectives

so p( non is defective ) = ( (86-5)/86) × ((86-5-1)/(86-1))            

p( non is defective ) =  ( 81 / 86) × (80/85)

p( non is defective ) =  0.8865

Therefore, the probability that the shipment is accepted is 0.8865
