What does the range of data tell you
stiv31 [10]

Answer:

Katelyn can complete 17 integer questions in one minute. Collin can also complete 17 integer questions in one minute. Which expr
BabaBlast [244]

Answer:

a: 17m + m

Step-by-step explanation:

Each one can answer 17 questions in 1 minute.

Each one can answer 17m questions in m minutes.

The total they can answer is 17m + 17m = 34m.

Every expression that is equal to 34m represents the amount they can both answer in the same number of minutes.

The expression we are looking for does not equal 34m.

a: 17m + m  = 18m

b: 34m  = 34m

c: 2(17m)  = 34m

d: 17m + 17m = 34m

Only choice a does not equal 34m.

Answer: a: 17m + m
