What makes rational algebraic expression undefined? a. When the numerator becomes 0
b. When the denominator becomes 0
c. When the value of the given variable is equal to O
d. When the restricted value is equal to 0

The answer is B.

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
