Find the measure of the angle of indicated in bold

130°

Step-by-step explanation:

22x -2 = 21x +4 ; because alternate interior angles are congruent

22x -21x = 4 +2; subtract 21x and add 2 to both sides

x= 6

the angle measure is

22*6 -2 = 130°

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.
