a)

b)

c)

Explanation -

a) 2/3 p + 10 = r

Value of r = 22 (given)

2/3 p + 10 = 22

2/3 p = 22- 10

2/3 p = 12

p = 12 × 3 /2

p = 6 × 3

p=18

b) (-17) + 5k = t

value of k = 4 (given)

(-17) +5 (4) = t

(-17) + 20 = t

3 = t

c) 0 = 5p - 3b

b= 2 (given)

0 = 5p - 3(2)

0 = 5p - 6

6 = 5p

6/5 = p

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.
