Answer:

1. 60 cm^2

2. 132.67 cm^2

3. 72.67 cm^2

Step-by-step explanation:

1. Area of rectangle

A = LW = 5 cm * 12 cm = 60 cm^2

2. Area of circle

A = (pi)r^2 = 3.14(6.5 cm)^2 = 132.67 cm^2

3. Area of shaded region

A = area of circle - area of rectangle

A = 132.7 cm^2 - 60 cm^2 = 72.67 cm^2

Answer:

See below in bold.

Step-by-step explanation:

1.   The area of the circle = 3.14 * radius^2.

The radius = 1/2 * 13 = 6.5 cm so the area is

3.14 * 6.5^2 = 132.67 cm^2 to the nearest hundredth.

2. Area of the rectangle = width * length =  5*12 = 60 cm^2.

3. Area of the shaded region =  area of the circle - area of the rectangle

=  132.67 - 69 = 72.67 cm^2 to the nearest hundredth.

20 POINS FOR ANSWER!!
inna [77]

Answer: the margin of error is 0.02

Step-by-step explanation:

Confidence interval for population proportion is written as

Sample proportion ± margin of error

If the confidence interval for this population proportion is (0.52, 0.56.), it means that the lower boundary is 0.52 and the upper boundary is 0.56

Let x represent the sample proportion and y represent the margin of error. Therefore,

x - y = 0.52

x + y = 0.56

Subtracting the second equation from the first equation, it becomes

- 2y = - 0.04

y = - 0.04/-2

y = 0.02
