Answer:

The expected number of the people at the reception whose favorite snack will be chips is 1152

Step-by-step explanation:

Given

The data in the above table and

Reception = 3600

Required

Predict the number of the people at the reception whose favorite snack will be chips.

The first step is to determine the total number of samples;

Total = Brownies + Cookies + Chips + Other

Total = 32 + 22 + 56 + 65

Total = 175

The next step is to determine the fraction of people whose favorite is chips

Fraction = \frac{Chips}{Total}

Fraction = \frac{56}{175}

The product of the above fraction and the expected number of people in the reception is the solution to this question;

Expected\ Number = \frac{56}{175} * 3600

Expected\ Number = \frac{56* 3600}{175}

Expected\ Number = \frac{201600}{175}

Expected\ Number = 1152

<em>Hence, the expected number of the people at the reception whose favorite snack will be chips is 1152</em>

A cylinder’s volume can be calculated by the formula V=pir^2h , where V stands for volume, R for the base radius and H for the c
sasho [114]

Answer:

Step-by-step explanation:

Formula

V pi * r^2 * h

Givens

r = 3 m

h = 6 m

pi = 3.14 when used.

Solution

V = pi r^2 * h

V = pi * 3^2 * 6

V = 9 * 6 * pi

V = 54 * pi  Volume in terms of pi

V = 54*3.14 Volume using a value for pi

V = 169.56 to the hundred's place.
