Question

(06.01 MC)

A restaurant manager recorded the number of people in different age groups who attended her food festival. She then created the following histogram:

Histogram with title Food Festival Participants, horizontal axis labeled Age Group (year) with bins 0 to 19, 20 to 39, 40 to 59, and 60 to 79 and vertical axis labeled Number of People with values from 0 to 60 at intervals of 10. The first bin goes to 20, the second goes to 40, the third goes to 60, and the last goes to 50.

Which of the following statements best compares the height of the bars of the histogram?

Answer 1

a)there are twice as many participants in the 60-79age group in the 0-19 age group
b)there are 3 times as many participants in the 40-59 age group than in the 0-19 age group
c)there are more participants in the 40-59 age group than in the 0-19 and 60-79
d)there are more participants in the 60-79 age group than in the 0-19 and 20-39 groups combined

Answer 2

C is phrased really weirdly and now it's confusing me

Answer 3

other than that, we can try to think our way through this

for (A)
There are 50 people in the 60-79 group right?
and there are 20 people in the 0-19 group right?

is 50 "twice as many" as 20?

Answer 4

yes

Answer 5

20 times 2 is 50?
are you sure?

Answer 6

no

Answer 7

"twice as many" as 20 is 40
since it is not 50

(A) would Not be our answer

Answer 8

i know D is not also

Answer 9

Good!

So if A is not
C is too confusing
and D is also not

what do we have left :)
