Jose and his family went to dinner at olive garden the total bill was $55.31 Jose decided to leave a 15% tip how much of a tip did the waiter receive

The answer would be that waiter will get $8.29.

Step-by-step explanation:

You would do 55.31 multiplyed by 0.15 to get the 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.
