A farmer grows apple, orange, lemon, banana, and pear trees. The number of trees planted this year is shown in the table above. Which of the following would best display the data?
Select the best answer.
Explanation:
A bar graph is the most appropriate way to display categorical data like the number of each type of tree planted by the farmer. In a bar graph, each type of tree can be represented by a separate bar, allowing for easy visual comparison of the quantities. Scatter plots are used to illustrate relationships between two sets of data, which is not the case here. Stem-and-leaf plots are more suitable for displaying numerical data in a grouped format, not categorical data like types of trees. Line graphs are typically used to portray trends or changes over time, making them less suitable for this scenario.

Therefore, choice A correctly represents the length of the rectangle in terms of X, making it the correct answer.
When the weights of newborn babies are graphed, the distribution of weights is symmetric with the majority of weights centered around a single peak. Which of the following describes the shape of this distribution?
Select the best answer.
Explanation:
The described distribution, where the majority of weights are centered around a single peak and symmetric, is referred to as bell-shaped. In a bell-shaped distribution, the data is symmetric around the mean, with most values clustering near the peak and tapering off towards the extremes. This pattern is commonly seen in normal distributions, such as the distribution of birth weights in newborns. The bell-shaped curve represents a typical symmetric distribution, indicating that most newborn weights fall close to the average weight with fewer extreme values. Therefore, the correct answer is 'Bell-shaped'.
A sweater that normally sells for $87 is marked 25% off. Which of the following estimates the sale price of the sweater?
Select the best answer.
Explanation:
To calculate the sale price after a 25% discount, you need to find 25% of the original price and subtract it from the original price. 25% of $87 is $21.75 ($87 x 0.25 = $21.75). Subtracting this from the original price gives you $87 - $21.75 = $65, which is the estimated sale price of the sweater.
What is the area of a circle with a diameter of 16 inches in terms of pi (π)?
Select the best answer.
Explanation:
To calculate the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is given as 16 inches, the radius (r) is half of that, which is 8 inches. By substituting r = 8 into the formula, you calculate the area as A = π(8)² = 64π square inches. Therefore, the correct answer is 64π in squared (Choice B). This calculation is derived from the concept of the radius being half of the diameter in a circle formula.
A worker earns $8000.00 per week before any tax deductions. The following taxes are deducted each week: $83.00 federal income tax, $38.00 state income tax, and $79.00 social security tax. How much will the worker make in 4 weeks after taxes are deducted?
Select the best answer.
Explanation:
To determine the worker's earnings in 4 weeks after taxes are deducted, start by calculating the total weekly tax deductions: $83.00 + $38.00 + $79.00 = $200.00. Subtract the total weekly tax deductions from the weekly earnings: $8000.00 - $200.00 = $7800.00. Now, to find the total earnings after 4 weeks, multiply the weekly earnings after deductions by 4: $7800.00 x 4 = $31,200.00. Therefore, the worker will make $31,200.00 in 4 weeks after taxes are deducted.
An athlete runs 4 miles in 28 minutes and then changes pace to run the next 4 miles in 32 minutes. Overall, what is the average time in minutes it takes the athlete to run 1 mile?
Select the best answer.
Explanation:
To calculate the average time per mile, we add the total time taken for both parts (28 minutes + 32 minutes = 60 minutes) and divide it by the total distance covered (8 miles). This gives us 60 minutes / 8 miles = 7.5 minutes per mile. Therefore, the correct answer is 7.5 minutes, representing the average time it takes the athlete to run 1 mile.
How should the frequency for each day of the week that students get up after 8 a.m. be best displayed from a class survey?
Select the best answer.
Explanation:
A bar graph is the most appropriate way to display the frequency of students getting up after 8 a.m. on each day of the week. Bar graphs are well-suited for comparing discrete categories, making them ideal for showing the frequency distribution of responses for each day. Each day of the week can be represented on the x-axis, and the frequency of students getting up after 8 a.m. on the y-axis. This allows for a clear visual comparison between the days, making it easy to see which days have a higher frequency of students waking up after 8 a.m. In this case, a bar graph is preferred over other options like scatter plots, histograms, or pie charts, as it provides a simple and effective way to visualize and compare the data across different days of the week.
When a person increases cycling speed, the rate of calories burned, distance traveled, and energy expended also increase. Which of the following is the independent variable?
