C. 1.9
To find the mean of each set of data, add up all the values and divide by the total number of values.
For the baseball team:
Mean = (0 + 0 + 0 + 1 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 4) / 15
Mean = 19 / 15
Mean = 1.27
For the French club:
Mean = (0 + 0 + 1 + 1 + 1 + 2 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 6) / 15
Mean = 30 / 15
Mean = 2
The difference of the means is:
2 - 1.27 = 0.73
Therefore, the closest answer option provided is 1.9.
Students on the baseball team and in the French club were asked how many pets they have. The results are shown.
Baseball Team: 0, 0, 0, 1, 1, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4
French Club: 0, 0, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 4, 6

To find the circumference of a circle with a radius of 3 1/2 meters, we can use the formula:
C = 2 * π * r
Given that the radius, r, is 3 1/2 meters, we can convert this to an improper fraction:
3 1/2 = 7/2
Now, substitute the value of π as 22/7:
C = 2 * (22/7) * 7/2
C = 44/7
C = 6 2/7 meters
Therefore, the circumference of the circle with a radius of 3 1/2 meters is approximately 6 2/7 meters. None of the answer options provided match this exact value, but the closest option is:
B. 7 meters.
C = 2 * π * r
Given that the radius, r, is 3 1/2 meters, we can convert this to an improper fraction:
3 1/2 = 7/2
Now, substitute the value of π as 22/7:
C = 2 * (22/7) * 7/2
C = 44/7
C = 6 2/7 meters
Therefore, the circumference of the circle with a radius of 3 1/2 meters is approximately 6 2/7 meters. None of the answer options provided match this exact value, but the closest option is:
B. 7 meters.
Two restaurants each surveyed diners to find out the ages of people eating at their restaurants. The box plots show the results of the surveys.
Two box plots.Short description, Two box plots.,Long description,
The two box plots show the age of diners in years for two restaurants.
The box plot for Restaurant A has whiskers that range from 11 to 58 years, and the box ranges from 22 to 47 years. A line divides the box at 37 years.
The box plot for Restaurant B has whiskers that range from 17 to 52 years, and the box ranges from 28 to 43 years. A line divides the box at 36 years.

Restaurant A has a wider range of age values as shown by the whisker plot. Therefore:
Restaurant A has (more variability) than Restaurant B, because the (spread) of data for Restaurant A is greater than that of Restaurant B.

To find the area of a circle, you can use the formula: Area = πr^2
Given that the radius of the circle is 8 cm, substitute this value into the formula:
Area = 3.14 * (8)^2
Area = 3.14 * 64
Area ≈ 200.96 square centimeters
Therefore, the approximate area of the circle is 200.96 square centimeters.
The closest answer option provided is:
C. 200.96 centimeters squared
Given that the radius of the circle is 8 cm, substitute this value into the formula:

To find which two numbers pi squared (π^2) is between on the number line that goes from 0 to 12, we need to calculate the value of π^2 first:
π^2 ≈ 3.14^2 ≈ 9.8596
Now, we compare this value to the numbers on the number line:
6 < 9.8596 < 7
Therefore, π squared is between 6 and 7 on the number line.
The correct option is:
A. 6 and 7
π^2 ≈ 3.14^2 ≈ 9.8596
Now, we compare this value to the numbers on the number line:
6 < 9.8596 < 7
Therefore, π squared is between 6 and 7 on the number line.
The correct option is:
A. 6 and 7
