Find the mystery number "c" using these facts about "c".
. 1.5 < c < 2
. "c" can be written as a fraction with one digit for the numerator and one digit for the denominator.
. both "c" and 1/c can be written as finite (non-repeating) decimals. what is this mystery number?

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.

14

step-by-step explanation:

14 x 3 = 42
