Which of the following types of numbers is irrational? A.) a whole number
B.) fractions
C.) the number pi
D.) a decimal that terminates

C

Step-by-step explanation:

the definition of an irrational number is an infinite decimal that has no repeating pattern. rational numbers can be converted into fractions.

A is incorrect because a whole number can be converted into a fraction.

      ex: 1 is also 3/3

B is incorrect because the definition of a rational number is that it can be converted into a fraction.

D is incorrect because a terminating decimal can be made into a fraction.

      ex: 4.5 is also 9/2

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.
