Can anyone tell me what number (a) is on this histogram? I know (b) is 40 but I'm stuck on the first question.

27 students

Step-by-step explanation:

If you add up all the students who scored 68+, then you get 27 students (add up the 3rd, 4th, 5th, and 6th bars)

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
