Chad bought a box of raisins. he gave 1/6 of it to one brother, 1/4 to another brother, & he kept the rest for himself. what fraction did he keep?

Fraction, that he gave to his brothers = 1/6 + 1/4 = 5/12

So, Fraction he kept for himself, 1 - 5/12 = 7/12

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

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.
