Answer:

10.5%

Step-by-step explanation:

The probability that a student took an accounting course, P(A)= 28.3%

The probability that a student took a statistics course P(A)= 31.3%

The probability that a student took accounting and statistics course,

P(A \cap S)=49.1\%

We want to determine the probability that a randomly selected student took an accounting or statistics course, P(A \cup S)

In probability theory,

P(A \cup S)=P(A)+P(S)-P(A \cap S)\\P(A \cup S)=28.3\%+31.3\%-49.1\%\\P(A \cup S)=0.283+0.313-0.491\\P(A \cup S)=0.105

The probability that a randomly selected student took an accounting or statistics course is 0.105 or 10.5%.

Serhud [2]

Answer:

y=10x+50

Explanation:

The line starts at point (0,50) which is the y intercept (how much he gets paid to visit house).The line crosses points (10,150) and (20,250) and the slope of these points are 100/10 which when simplified equals 10x which is how much money he gets paid by the hour(x=hours) so y=10x plus the y intercept y=10x+50
