Dariel runs 3 miles in 30 minutes. What is his rate per hour?

6 mph

Step-by-step explanation:

I divided 3 by 30 to find the miles per minute (.1) multiplied it by 60 minutes and got 6.

or you could just double the 3 because Dariel is running 2x as long as the original length and get the same answer

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

hi there!

the answer will be d: 2
