1-20: Make it 0 units tall (change nothing)

21-40: Make it 1 unit tall

41-60: Make it 3 units tall

61-80: Make it 2 units tall

81-100: Make it 2 units tall

Step-by-step explanation:

1-20: (0 numbers)

21-40: 33 (1 number)

41-60: 43, 44, 52 (3 numbers)

61-80: 75, 79 (2 numbers)

81-100: 86, 89 (2 numbers)

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.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
