Answer:
Graph # 3
Step-by-step explanation:
-2x + 5y > 15 Let x = 0 solve for y
-2(0) + 5y = 15 change the > to an =
5y = 15
y =3 Point (0, 5) is on the graph
Graph # 3 is correct because the y-intercept is 5
x y
0 3 -2(0) + 5y = 15; 5y = 15
5 5 -2(5) + 5y = 15; -10 + 5y = 15; 5y = 25; y = 5
10 7 -2(10) + 5y = 15; -20 + 5y = 15; 5y = 35; y = 7
The graph > the line is dotted and you will shade above the line
Part A:What percentage of the total students surveyed like both watching television and reading?
The total amount of student is 230
The amount of students that like to read and watch television is 80
As a fraction it is 80/230
Turn that to a percentage
It is:34.7826%
Part A=34.7826%
Part B:What is the probability that a student does not like watching television also does not like reading?
On the table it shows 20
So the probability is 20/230
Part B=20/230
