What is the result of 8 decreased by 5%
maybe show work or tell how you got it ?

7.6

Step-by-step explanation:

95 ÷ 100 × 8 = 7.6

7.6

Step-by-step explanation:

5% = 0.05

0.05 X 8 is 0.4. This is an increase.

To decrease, just subtract it.

8-0.4=7.6

8-5% is 7.6

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.
