students at sunnyvale middle school volunteered to work a 2 - hour shift at a car wash fundraiser. the table shows the number of people who worked each shift and how many cars they washed. is the relationship between the number of cars washed and the number of workers proportional? complete the statement. the number of cars washed per person? the same for each number of workers, so the relationship is? people working cars washed 4 8 6 12 8 20 10 25
Answer
Explanation:
Step1: Calculate cars - per - person for first row
For the first row, with 4 people and 8 cars washed, the number of cars washed per person is $\frac{8}{4}=2$.
Step2: Calculate cars - per - person for second row
For the second row, with 6 people and 12 cars washed, the number of cars washed per person is $\frac{12}{6}=2$.
Step3: Calculate cars - per - person for third row
For the third row, with 8 people and 20 cars washed, the number of cars washed per person is $\frac{20}{8}=2.5$.
Step4: Determine proportionality
Since the number of cars washed per person is not the same for all rows (2, 2, 2.5), the relationship is not proportional.
Answer:
is not; not proportional
