Question

Of students taking a course, 7/15 play a sport and 3/5 play a musical instrument.The probability that a student plays a sport or a musical instrument is 2/3. What is the probability that a student play a sport and a musical instrument?

Answer 1

7/15

Explanation:

Function 1:

(0,45)(1,75)

slope (rate of change) = (75 - 45) / (1 - 0) = 30

y = mx + b

slope(m) = 30

(0,45)...x = 0 and y = 45

now we sub and find b, the y int

45 = 30(0) + b

45 = b

so ur equation is y = 30x + 45....slope (rate of change) = 30...y int = 45

Function 2 :

y = 40x + 50.....slope(rate of change) = 40...y int = 50

Function 2 has a greater rate of change then Function 1 --- True

Function 2 has a greater y int then Function 1 --- True

Answer 2

13/15 because 3/5 with the lcd is 15 so 7 plus 6 is 13
