When a rational number is written as a fraction, which statement is always true about the numerator and the denominator of the fraction?A. They are both integers. C.They are both natural numbers. B.They are both prime numbers. D.They are both composite numbers

Step-by-step explanation:

They are both natural numbers

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

b. they are parallel and will never intersect.
