Answer 2

Using the percentage concept, it is found that the estimate of the percentage of millionaires in these cities is of 9.25%.

What is a percentage?

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

Researching the problem on the internet, it is found that:

A total of 45 + 34 + 37 + 32 + 455 + 266 + 363 + 368 = 1600 people were surveyed, hence b = 1600.Of those, 45 + 34 + 37 + 32 = 148 are millionaires, hence a = 148.

Then:

[tex]P = \frac{148}{1600} \times 100\% = 9.25\%[/tex]

The estimate of the percentage of millionaires in these cities is of 9.25%.

Answers

Answer:

Step-by-step explanation:

1444 x 0.2

288.8

1444+288.8 = 1732.8

1732.8 x 0.2

346.56

1732.8 + 346.56 = 2079.36

2079.36 x 0.2

2079.36 + 415.87 = 2495.23

2495.23  x 0.2

2495.23 + 499.05 = 2994.28

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.
