Answer:

Step-by-step explanation:
Given
Cost of Textbooks ---- Frequency
$25 up to $35 ----- 2
$35 up to $45 ------- 5
$45 up to $55 ------- 7
$55 up to $65 ------ 20
$65 up to $75 ---- -- 16
Required
Determine the relative class frequency for the $25 up to $35 class
First, we need to get the total frequency


Next, is to write out the frequency of $25 up to $35 class

Divide this frequency by the total frequency; This gives the relative frequency



Hence;
Option D answers the question
Answer:
Quadrant IV, or the fourth quadrant.
Step-by-step explanation:
Plot your points, first plotting 5, then plotting -2.
Answer:
1. y = sin(x²+C)
2. see below
Step-by-step explanation:
1. 
separation of variables

integration both sides
you should get :
remember constant of integration!!
2. y = sin(x²+C)
3 = sin(0+C)
y(0) = 3 does not have a solution because our sin graph is not shifted vertically or multiplied by a factor whose absolute value is greater than 1, so our range is [-1,1] and 3 is not part of this range
I'll just take the points thanks XD
