Write an equation to represent the relationship between the angles in the diagram below. Then solve your equation to find w.

w+76+w = 180

w = 52

Step-by-step explanation:

The angle between the w's is a vertical angle to 76, so it equals 76 because vertical angles are equal

w+76+w = 180 since it forms a straight line

Combine like terms

2w+76 =180

Subtract 76 from each side

2w+76-76 =180-76

2w = 104

Divide by 2

w =52

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.
