Answer:

The maximum value of the confidence interval for this set of survey results is 51.73%.

Step-by-step explanation:

A confidence interval has two bounds, a lower bound and an upper bound.

These bounds depend on the sample proportion and on the margin of error.

The lower bound is the sample proportion subtracted by the margin of error.

The upper bound is the margin of error added to the sample proportion.

In this question:

Sample proportion: 46.1%

Margin of error: 5.63%.

Maximum value is the upper bound:

46.1+5.63 = 51.73

The maximum value of the confidence interval for this set of survey results is 51.73%.

Keisha just deposited a total of 900 into savings accounts at two different banks. the 550 she deposited at bank A will earn 2.2
mars1129 [50]

Answer:

F.

Step-by-step explanation:

Find how much interest she will earn from bank A:

100% = 550

1% = 550 ÷ 100 = 5.5

2.25% = 12.375

Find how much interest she will earn from bank B:

900 - 550 = 350

100% = 350

1% = 350 ÷ 100 = 3.5

3% = 3.5 x 3 = 10.5

Find out how much money she will earn from both banks of their interest:

10.5 + 12.375 = 22.875

Find out how much money she will earn from both banks of their interest in 2 years:

22.875 x 2 = 45.75

Find out how much she earns from both banks including interest:

900 + 45.75 = 945.75
