Answer these two questions (repost bc last answer was wrong):
Suppose that 60% of the students at your school favor a proposed school policy that would ban cell phones at school. Also suppose that every student in your class selected a different random sample of 50 students from your school and calculated the proportion of students in the sample who favors the ban.

5. If your class constructed a dot plot of all these sample proportions, where would you expect the dot plot to be centered?

6. If every student had selected a random sample of size 25 instead of a sample of size 50, would you expect a dot plot of the sample proportions to be more spread out or less spread out than in a dot plot of sample proportions for samples of size 50?

Theresa uses a unique box in the shape of a trapezoidal prism for her specialty candles. The area of the base of the box for the smaller candle is 125 cm2 and the box is 12 cm tall. The box used for the larger candle has a base whose area is 160% that of the smaller box, and it is 6 centimeters taller.
What percent of the volume of the smaller box is the volume of the larger box?
Answer:

Answers

Answer:

41.7%

Step-by-step explanation:

100%----125

10%------125/100 x 10

=12.5

160%-----12.5 x 16

=200

volume of small box = 200 x (12+6)

= 3600

volume of large box = 125 x 16

= 1500

percentage of volume of small box is the volume of large box

= 1500/3600 x 100%

=41.667% (5 s.f)

=41.7% (3s.f)

7. Terrance needs to find the lateral surface area of the box shown below. Assuming that the base is the bottom of the prism, which of the expressions below will give him the correct lateral surface area?

Answers

The expression that will give the correct lateral surface area of the rectangular prism = (14.5 + 14.5 + 7 + 7)(8.6)

What is the Lateral Surface Area of a Rectangular Prism?

The lateral surface area (LSA) = 2(l + w)h

Given the following:

l = 14.5 w = 7h = 8.6

Lateral surface area of the prism = 2(l + w)h = 2(14.5 + 7)8.6

Lateral surface area of the prism = (14.5 + 14.5 + 7 + 7)(8.6)

A convenience store supplies two types of protein bars. One protein bar has 320 calories in the 2-ounce size. How many calories are in the 3-ounce size of the bar?

Answers

Since one protein bar has 320 calories in a 2-ounce size, we can divide 320 by 2. When solving, we get 160. This means there are 160 calories in one protein bar.

We are trying to find how much calories are in the 3-ounce size, so we must multiply 160 by 3.

The final answer to your question is 480. There are 480 calories in the 3-ounce protein bar.

when he sorts the class's scores on the last test, the teacher notices that exactly 12 students scored better than Clare and exactly 12 students scored worse than Clare. Does this mean that Clare's score on the test is the median? Explain your reasoning.

Answers

Answer:

Yes, Clare's score on the test is the median.

Step-by-step explanation: Yes, because if we line up the scores from least to greatest and continue to cross off a score on each side, Clare's score will be exactly in the middle.

Yes clare’s test score is the median. This is true because the median is the middle of the data so if there are equal numbers of 12 below and above her score that would mean her score is in the middle and would be considered the median

When a figure is reflected, it is flipped. Since it is reflected on the x-axis, that is the direction it is flipped in. When flipped, the coordinate of the bottom left corner is (1, 1). When you move the figure over 5 units (which is what translating is), the coordinates are (-4, 1) which matches with the corner of the second given figure.
