B. 110
C. 120
D. 130

6. You are surveying students to find out their opinion of the quality of food served in the school cafeteria. You decide to poll only those students who buy hot lunch on a particular day. Is your sample random? Please explain

Answers

Answer 1

Answer: 5. If 18 customers out of 30 prefer coffee, we can find the ratio that will be used to estimate how many customers out of 200 will prefer coffee. We can do this by dividing 18 by 30 to give us 0.6. Then, we multiply 200 by 0.6 to give us 120. Therefore, the answer is 120.

6. No, your sample is not random, as you are only asking how the food is for students that only buy hot lunches. If it was random, you'd be asking any student how the food is, not just specifically one group of people.

Answer 2

Answer: the answer for the first question would be c) 120

A shoe box is 10 inches long and 6 inches wide. It is 3 inches tall. Sage is wrapping the shoe box and determined that she needs 20% more than the total surface area in gift wrap to cover the box and account for overlap. How many square inches of gift wrap does she need?

Answers

Answer: $360\ in^2$

Step-by-step explanation:

For this exercise you need to use the folllowing formula for calculate the Surface area of a Rectangular prism:

$SA = 2wl + 2lh + 2hw$

Where "l" is the length, "w" is the width and "h" is the height of the prism.

In this case you can identify that:

$l=10\ in\n\nw=6\ in\n\nh=3\ in$

Therefore, substituting values, you get that the surface area of the shoe box is:

$SA = 2(6\ in)(10\ in) + 2(10\ in)(3\ in) + 2(10\ in)(6\ in)\n\nSA=300\ in^2$

The 20% of this surface area is:

$(300\ in^2)(0.20)=60\ in^2$

Since she needs 20% more than the total surface area in gift wrap to cover the box and account for overlap, you get that total amount of square inches of gift wrap that she needs is:

$Total=300\ in^2+60\ in^2=360\ in^2$
