Deundre wants to conduct a survey at White Station Middle School, which has 1,200 students. He wants to learn how many days on average students eat the school lunch per week. He knows that it would be too time consuming to ask every single student to complete the survey, so he decided to take a sample (a subset of a population) of the entire school population and only ask 60 students. What is the sample in this example.

Answers

Answer 1

Answer:

The sample size is 60.

Step-by-step explanation:

He only asks 60 people so that is his sample, the other students (1200) is the population he is trying to make a judgement about.

Which shape has a greater perimeter?

Answers

Answer: Shape B, which is the thin and long rectangle.

Step-by-step explanation:

Shape A:

4 + 4 + 8 + 8

4+4 = 8

8 + 8 = 16

16 + 8 = 24

Shape A has a perimeter of 24.

Shape B:

2 + 2 + 11 + 11

2 + 2 = 4

11 + 11 = 22

22 + 4 = 26

Shape B has a perimeter of 26.

What is the surface area of the solid that this net can form?
A. 106 square centimeters
B. 150 square centimeters
C. 210 square centimeters
D. 270 square centimeters

Answers

C. 210 sq cm.

13 + 12 + 5 = 30 (length)
30 • 5 = 150 sq cm (the total area of the long rectangles across)

12 • 5 = 60 sq cm
(no need to divide by 2 even if they are triangles because there are two on either side so they would cancel out)

150 + 60 = 210 sq cm.

The cone and cylinder above have the same radius and height. The volume of the cone is 162 cubic inches. What is the volume of the cylinder?

A. 54 cubic inches

B. 81 cubic inches

C. 324 cubic inches

D. 486 cubic inches

Answers

The answer is D because if a cone and a cylinder have the same radius and height, the volume of a cone is 1/3 of the volume of a cylinder. So you would need to multiply 162 by 3 to get the volume of the cylinder, which is 486

The volume of the cylinder is 486 cubic inches.

What is Volume?

Volume of a three dimensional shape is the space occupied by the shape.

Given that,

Radius and height of the cylinder and the cone are same.

Let r and h be the radius and height of each of the cylinder and the cone.

Volume of the Cone = [tex]\frac{1}{3}[/tex] π r² h

Volume of the cylinder = π r² h

We have, volume of the cone is 162 cubic inches.

[tex]\frac{1}{3}[/tex] π r² h = 162

Multiplying both sides by 3,

π r² h = 162 × 3

π r² h = 486 cubic inches

Hence the volume of the cylinder is 486 cubic inches.

Step-by-step explanation:

S=Saturday

P(F or S)= 20/90+22/90-20/90=22/90

22/90 as percentage is 24.44 percent

Answer:

For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.

Step-by-step explanation:

Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.

Erik transformed the equation y = 2(x − 2)^2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)^2 + 5
y = 2(x^2 − 4x + 4) + 5
y = 2x^2 − 8x + 8 + 5
y = 2x^2 − 8x + 13
A. No. The error is in the second line: the expanded form of (x − 2)^2 is x^2 − 4.
B. No. The error is in the third line: the product of 2 and x^2 − 4x + 4 is 2x^2 − 4x + 4.
C. No. The error is in the fourth line: the sum of 8 and 5 is 12.
D. Yes. Erik is correct in his transformation from vertex form to standard form.
