Answer:

The cost per square inch of the pie is $0.111 or 11 cents

Step-by-step explanation:

The shape of a pie is circular.

The area of a circle (pie) = πr²

From the question ,

Diameter = 12 inches

Radius = Diameter/2

Radius = 12 inches/2

Radius = 6 inches.

Hence, the area of the pie = π × 6²

= 113.09733553 square inches

A pie costs $12.55

The cost per square inches of the pie is calculated as:

113.09733553 square inches = $12.55

1 square inch = $x

Cross Multiply

113.09733553x = $12.55

x = $12.55/113.09733553

x = $0.1109663631

Approximately

x = $0.111

Therefore, the cost per square inch of the pie is $0.111 or 11 cents

Find the mean and standard deviation for the set of data.
dem82 [27]

The mean and standard deviation for the set of data will be 16 and 5.87. Then the correct option is A.

<h3>What is a standard deviation?</h3>

It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.

The set of data is given below.

16, 22, 8, 5, 20, 18, 14, 17, 24

The mean of the data set will be

μ = (16 + 22 + 8 + 5 + 20 + 18 + 14 + 17 + 24) / 9

μ = 144 / 9

μ = 16

Then the standard deviation of the data set will be

\rm \sigma = \sqrt{\dfrac{\Sigma (x_i - \mu)^2}{n}} \\\sigma = \sqrt{\dfrac{(16 - 16)^2 +(22 - 16)^2 + (8-16)^2 + ......+(24-16)^2  }{9}} \\\sigma = \sqrt{\dfrac{310}{9}}\\

Simplify the expression further, then we have

σ = √34.44

σ = 5.87

The mean and standard deviation for the set of data will be 16 and 5.87.

Then the correct option is A.

More about the standard deviation link is given below.
