What is the distance between point a (−1, 3) and point b (−7, 3) ?

6

Explanation:

Use the distance formula to determine the distance between the two points.

√(x2 - x1)^2 + (y2 - y1)^2

Substitute the actual values of the points into the distance formula.

√( (-7) - (-1))^2 + (3 - 3)^2

Then simplify.

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.

answer:     true
