Answer:
The angles are supplementary.
Step-by-step explanation:
Angles that add up to 90° are complementary, while angles that add up to 180° are supplementary.
Answer:
y = 2x
linear equations are just finding the right ratio and putting it in y = mx+b format
this graph is saying that two dollars are earned for every ticket sold, a 2:1 ratio.
so the equation would be y = 2x, two being the amount of money collected for one ticket, and x being the number of tickets sold.
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
The discount is $.40 (1.20 - 0.80)
To find the discount you take (0.40/1.20) * 100
=.33 * 100
The discount is 33%
