Please solve these (add explaination)

a) 26

b) 14

Step-by-step explanation:

Given Formula:

x h

Steps for A:

x 4

5+8=13

13÷2=6.5

6.5 x 4

= 26

Steps for B:

x 4

1+6=7

7÷2=3.5

3.5 x 4

= 14

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.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
