Question

I sent it again: PLEASE ANSWER QUICK IM CONFUSED

Answer 1

Step-by-step explanation:

3a.

there are 40 students.

each one had to get to school one way or another. so, all of them have to be in the table in one category.

I am just surprised that "car" is not an option there.

anyway, we have

11 + 7 + 9 + 6 = 33

so, there are 40-33 = 7 students left for the train category.

3b.

I cannot draw it for you.

but you need to consider the following table :

all 40 students are the full 360° of the circle.

school-bus are 11 students = 11/40 × 360 = 11×9 = 99°

public bus are 7 students = 7/40 × 360 = 7 × 9 = 63°

walk are 9 students = 9/40 × 360 = 9 × 9 = 81°

bicycle are 6 students = 6/40 × 360 = 6×9 = 54°

train are 7 students = 7/40 × 360 = 7 × 9 = 63°

as you can see, the sum is again 40 students and 360°.

you need to draw these 5 pie slices with these angles.

and in each slice you write the number of students in that category.

together, side by side, all 5 slices will fill the whole circle.
