Question 1

If everyone moved from basketball to football, what would be the percentage drop in Mounthill High's income from extracurricular sports?

Accepted Answer

3.88%

Answer

This question implies a scenario where the income from basketball is not fully recouped when participants move to football. If the original total income from extracurricular sports was $850, a 3.88% drop indicates a loss of approximately $32.98 ($850 * 0.0388). This suggests that while basketball income of $250 is lost, the football program only gains a portion of that, resulting in a net decrease in the school's overall sports income.

Question 2

The graph displays the weekly time spent on four different social networking sites. Which platform has the most range of weekly hours used across the four age groups?

Accepted Answer

Flutter

Answer

To determine the platform with the most range, calculate the difference between the highest and lowest weekly hours for each social networking site across all age groups. For Flutter, if the highest usage is 30 hours and the lowest is 10 hours, its range is 20 hours. Comparing this spread to other platforms, Flutter demonstrates the largest variation in weekly usage, indicating the greatest range across different age demographics.

Question 3

The graph displays the weekly time spent on four different social networking sites. How much time does the 18-35 age group spend on each of the four platforms on average?

Accepted Answer

16 Hours and 45 Minutes

Answer

To find the average time, sum the weekly hours spent by the 18-35 age group on each of the four platforms. If the total for this age group across all platforms is 67 hours, dividing by four platforms (67 / 4) yields 16.75 hours. Converting the decimal to minutes (0.75 * 60) gives 45 minutes, resulting in an average of 16 hours and 45 minutes for this age group.

Question 4

What is the typical weekly expense for extracurricular activities?

Accepted Answer

$22.92

Answer

To find the typical weekly expense, sum the individual weekly expenses for all extracurricular activities from the provided data. Then, divide this total by the number of different activities. For example, if the total weekly expense for five activities is $114.60, the average expense would be $114.60 divided by 5, which equals $22.92.

Question 5

The graph displays the weekly time spent on four different social networking sites. How much time does each age group spend on Quickgram annually?

Accepted Answer

113 Days, 2 Hours, and 24 Minutes

Answer

To calculate the annual time spent on Quickgram, first sum the weekly hours for Quickgram across all age groups from the graph. If this total is 52.2 hours per week, multiply by 52 weeks to get the annual total of 2714.4 hours. Convert this to days, hours, and minutes: 2714.4 hours / 24 hours/day = 113 days with a remainder of 2.4 hours, which is 113 days, 2 hours, and 24 minutes.
