10) Can a triangle have two 90° angles?

no

Step-by-step explanation:

a triangle can only have one right angle or it wouldn't be a triangle

No

Step-by-step explanation:

Only Quadrilaterals have 2 or more 90° Because 90° means an angle which looks like L and it is impossible for triangle to have 2 90°

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.

the answer is d on edge
