You work 20 hours a week at a store in our $8.50 per hour. at another job you earn $8.00 per hour and can work as many hours as you want. if you want to earn $370 for the week, how many hours will you need to work at the second job?

For the second job you work for $8.00 per hour and you want to make $370 for the week so its just simple division.

$370/$8.00 is 46.25 hours a day which means you will have to work close to 46-47 hours a day to make $370 in a week.

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.
