Which equation has both 5 and -5 as possible values of y?

Consider : y² = 25

⇒ y =

We know that : 5² = 25 and also (-5)² = 25

⇒ y =

⇒ y = +5 or -5

So, The Answer is C

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.

people grow faster than other people.
