Javier read a report that said the probability that a randomly selected American is left-handed is 14%. He was curious how many left-handed
students to expect in a class of 30 students.
He simulated 100 classes of 30 students where each student selected
had a 0.14 probability of being left-handed.
Javier counted how many left-handed students were in each simulated
class. Here are his results:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

the one below it is a function

i can you with this answer
