Sally invests $10,500 in an account that earns 6% annual simple interest. Assuming she makes no additional deposits or withdrawa
Fittoniya [83]

Answer: $2520

Step-by-step explanation:

The simple Interest earned on a deposit of P that has a rate of r% and a period of t years can be calculated by using the formula:

(P × R × T)/100

where P is principal

R is rate

T is time

P=$10,500

R=6%

T=4 years

Therefore:

Interest= (10500 × 6 × 4)/100

= 252000/100

= 2520

Sally will earn $2520 as interest after 4 years.

Parker has a part-time job picking apples. Let the random variable A represent the number of baskets of apples picked each day.
makkiz [27]

Answer:

<u>The correct answer is B. μ = US$87.50 and σ = US$6.50</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of baskets of apples picked each day by Parker = A

Mean of A = 4.5 baskets

Standard deviation = 1.3 baskets

Daily payment received by Parker = US$ 65 + US$ 5 per basket

2. What are the mean μ and standard deviation σ of Parker’s daily pay?

Let's find out the mean and standard deviation of Parker's daily pay:

Daily payment received by Parker = US$ 65 + US$ 5 per basket

Daily payment mean received by Parker = 65 + 5 * 4.5

Daily payment mean received by Parker = 87.5

Standard deviation in US$ = 1.3 * 5

Standard deviation in US$ = 6.5

<u>The correct answer is B. μ = US$87.50 and σ = US$6.50</u>
