Your mom and dad are having a disagreement on who drove further last week. The number of miles drove each day for the week are listed below: Mom: 32, 41, 36, 54, 32, 12, 24 Dad: 26, 24, 10, 18, 40, 21, 15

Mom has the greater median and mean, so she generally drove farther last week than Dad.

Dad has the greater median and mean, so she generally drove farther last week than Mom.

Dad has the greater median and Mom has the greater mean, so Dad generally drove farther last week than Mom.

Mom has the greater median and Dad has the greater mean, so Mom generally drove farther last month than Dad.

The table below shows temperatures for a 6-day period in January. Day: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday Balance: -2, 4, -8, -6, 8, -3 a) Find the range of balances for the 6-day period (the range is the difference between highest and lowest number).

The range is 16 (8 - (-8) = 16).

The range is 10 (8 - (-2) = 10).

The range is 11 (4 - (-7) = 11).

Based on the given six balances, what is the average balance for the 6-day period rounded to the nearest tenths?

The average is -1.2 ((-2 + 4 + -8 + -6 + 8 + -3)/6 = -1.166... ≈ -1.2).

The average is 1.2 ((-2 + 4 + -8 + -6 + 8 + -3)/6 = 1.166... ≈ 1.2).

The average is 0.0 ((-2 + 4 + -8 + -6 + 8 + -3)/6 = 0).

The average is -2.0 ((-2 + 4 + -8 + -6 + 8 + -3)/6 = -2).

Mr. Bass gave two social studies tests, and the scores are represented in the box and whisker plot below. Part A: Calculate the following for each: Test 1 Range: ____________ Median: ____________ Interquartile Range (IQR): ____________ Test 2 Range: ____________ Median: ____________ Interquartile Range (IQR): ____________ (Refer to the box and whisker plot diagram for the scores.)

Test 1: Range: 95 - 15 = 80 Median: 55 Interquartile Range (IQR): 70 - 40 = 30 Test 2: Range: 90 - 30 = 60 Median: 50 Interquartile Range (IQR): 60 - 40 = 20

Test 1: Range: 90 - 10 = 80 Median: 60 Interquartile Range (IQR): 75 - 35 = 40 Test 2: Range: 95 - 25 = 70 Median: 55 Interquartile Range (IQR): 65 - 45 = 20

Test 1: Range: 95 - 15 = 70 Median: 50 Interquartile Range (IQR): 70 - 45 = 25 Test 2: Range: 90 - 30 = 60 Median: 55 Interquartile Range (IQR): 60 - 35 = 25

Test 1: Range: 100 - 20 = 80 Median: 55 Interquartile Range (IQR): 70 - 40 = 30 Test 2: Range: 90 - 35 = 55 Median: 50 Interquartile Range (IQR): 65 - 40 = 25

On which test did the students perform better? How do you know? Refer to a measure of center above.

The students performed better on the test with the higher mean score, as shown by the measure of center.

The students performed better on the test with the lower mean score, as shown by the measure of center.

The students performed better on the test with the higher range, as shown by the measure of center.

The students performed better on the test with the lower range, as shown by the measure of center.

Part C: The test with the higher measure of variation showed more variability. Which test was it?

Test A, because it had a higher standard deviation.

Test B, because it had a lower standard deviation.

Test A, because it had a lower range.

Test B, because it had a higher mean.

Find the circumference and area of the circle rounded to the nearest tenths. (The radius of the circle is 4.2 yd.)

Circumference = $$2\pi \times 4.2$$ ≈ 26.4 yd Area = $$\pi \times (4.2)^2$$ ≈ 55.4 yd²

Circumference = $$2\pi \times 4.2$$ ≈ 21.0 yd Area = $$\pi \times (4.2)^2$$ ≈ 40.0 yd²

Circumference = $$2\pi \times 4.2$$ ≈ 30.0 yd Area = $$\pi \times (4.2)^2$$ ≈ 60.0 yd²

Circumference = $$2\pi \times 4.2$$ ≈ 20.0 yd Area = $$\pi \times (4.2)^2$$ ≈ 50.0 yd²

Mia is ordering ice cream at the local ice cream shop. She can choose from chocolate, vanilla, or strawberry ice cream with sprinkles or nuts. How many choices does Mia have if she chooses one flavor of ice cream with one topping? Show your work.

6 choices (3 flavors × 2 toppings = 6)

3 choices (one for each flavor)

2 choices (one for each topping)

9 choices (3 flavors × 3 toppings = 9)

What is the probability of choosing Lentil, Caesar or Macaroni, Turkey or Ham?

4 out of 12, or 1/3 (since there are 12 possible combinations and 4 combinations that fit the criteria).

2 out of 12, or 1/6 (since there are 12 possible combinations and 2 combinations that fit the criteria).

6 out of 12, or 1/2 (since there are 12 possible combinations and 6 combinations that fit the criteria).

8 out of 12, or 2/3 (since there are 12 possible combinations and 8 combinations that fit the criteria).

The students in a middle school were surveyed about the amount of time they spend per day using computers for schoolwork. The students were divided into two age groups. The results of the survey are shown in the line plots. Part A: Determine the measures of central tendency (mean, median, and mode) of both data sets for Ages 11-12 and Ages 13-14.

Ages 11-12: Mean = 75, Median = 75, Mode = 60 Ages 13-14: Mean = 90, Median = 90, Mode = 90

Ages 11-12: Mean = 80, Median = 70, Mode = 75 Ages 13-14: Mean = 85, Median = 95, Mode = 100

Ages 11-12: Mean = 70, Median = 80, Mode = 75 Ages 13-14: Mean = 95, Median = 85, Mode = 80

Ages 11-12: Mean = 60, Median = 60, Mode = 75 Ages 13-14: Mean = 100, Median = 100, Mode = 95

The students in a middle school were surveyed about the amount of time they spend per day using computers for schoolwork. The students were divided into two age groups. The results of the survey are shown in the line plots. Part B: Which age group generally spent more time on a computer for their schoolwork? Refer to a measure of central tendency (mean, median or mode) to support your conclusion.

Ages 13-14 generally spent more time on a computer for their schoolwork, as their mean, median, and mode are all higher than those of Ages 11-12.

Ages 11-12 generally spent more time on a computer for their schoolwork, as their mean, median, and mode are all higher than those of Ages 13-14.

Both age groups spent the same amount of time on a computer for their schoolwork, as their mean, median, and mode are equal.

Neither age group spent more time on a computer for their schoolwork, as there is no clear difference in their mean, median, or mode.
