Answer:
There is no correlation.
Step-by-step explanation:
The points are far spread and does not give any correlation.
x is less than or equal to -2.
x is greater than -5.
When x is less than something, the arrow must go left. <———
When x is equal to a number, the dot must be filled in. •
When x is greater than a number, the arrow should go right, toward the greater values. ——>
When x isn’t equal to the number, the circle is not colored in. ⭕️

Answer:
a. 205320
b. 34220
c. 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
Step-by-step explanation:
a) The number of ways to dustribute exams among the TA's is:
n / (n - r)!
n= number of things to choose from
r= Choosing r number
60P3= 60! / (60 - 3)!
(60)(59)(58)(57)! / (57)!
=205320
B) The number of ways to dustribute the exams among the TA's is:
n! /(n - r)! r!
60C3= 60! /(60 - 3)! 3!
= 60!/ 57! 3!
= 60 × 59 × 58 / 3 × 2 × 1
= 34220
C) The required number of ways is:
60C25 + 60C20 + 60C15
= 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
Say you have 7/2 as your improper fraction. How many times does 2 go into 7? 3 Times with one left over. Your answer would be
3 1/2
Use the terms and variables given to find an equation to find the answer.
Price= $2 + .12xminutes
P=2+0.12m
Then, plug in known variables to find the final answer.
15.08=2+0.12m
13.08=.12m
m=13.08/.12
m=109 minutes
