In OH, IR = jk, mik = (11x + 2)", and mjk = (12x - 7). What is the measure of ik)?

mik) =

Intro

Done

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.

vertical=18cm horizontal=18cm hypotenuse=25.5

step-by-step explanation:

the answer for the second equation is (4,0)
