Answers & Explanations

1. B

The figure is a pie chart, a circular diagram that shows the relative amounts of each variable as a slice of the whole circle. The larger the amount of the variable, the larger the slice. In add-on, the percentage of each variable, or recycled fabric, is shown next to each slice. In this chart, newspaper is the most common recycled material, or the largest variable, representing 40% of the total. The adjacent largest is glass, at 25% of the total. All the other materials correspond smaller portions of the total.

2. E

The nautical chart indicates that twoscore% of the total recycled material is paper. Since 50,000 tons of fabric are recycled every month, the total amount of newspaper will be 40% of 50,000 tons, or 40/100*50,000=20,000 tons.

3. A

The hateful, or average, of the distribution can exist computed past multiplying each form past the number of students obtaining it, summing, and then dividing by the total number of students. Here,northward= iv.2. The median is the valuep for which an equal number of students have received grades that are higher or lower thanp. Hither,p = 4. The mode is the most frequently obtained grade, and here,q = 3. Thus,n >p >q.

4. C

Slope is defined to be (modify in y) / (modify in x). Every bit the line goes from the point (-5,-3) to (0,0), y increases by three and x increases past v. Thus, the slope is iii/v. Since the line is direct, the slope is the same throughout. In other words, each fourth dimension y increases by three units, x volition increment past v units. It is given in the problem that the y-coordinate of P2 is 3. So, every bit we move along the line from the origin (0,0) to P2, y has increased by 3 units. Therefore, 10 will increase by five and and then the x-coordinate of P2 is 5.

5. A

Read the values of each bar from the vertical axis: (a) = 3; (b) = four; (c) = 6; and (d) = ii. Since (c) – (b) = 6 – iv = 2, and (b) – (d) = iv – 2 = 2, option A is correct.

6. A

The graph is at its highest point for the beginning information point, which corresponds to 12 inches of rain during the month of January.

7. D

Rainfall in October increases to vi inches from 1 inch in September. This represents an increase of 5 inches. None of the other month-to-month differences are every bit groovy.

8. B

360 degrees ÷ iii = 120 degrees

nine. B

First, decide the proportion of students in Grade v. Since the total number of students is 180, this proportion is 36/180=0.2 or 20%. So, determine the same proportion of the full prizes, which is xx% of xx, or iv.
