Answer:

  • We have two points so let's use them effectively
  • We know that the x changes by 3 and the y changes by 4
  • Hence to get to y=20 we moved 2 times (8 units) so it's 9+ 3 + 3= 15
  • So x= 15
  • Now for y We have an x= 18, from 9 we moved 9 units of 3 total intervals: 4+4+4+12= 24
  • y=24

What is the probability that the selected consumer is 35–55 years old or likes crunchicles?
Tju [1.3M]

The probability that the selected consumer is 35–55 years old or likes Crunchicles is 0.444.

Number of people who liked Crunchicles = 121

Number of people who are 35 - 55 years of age = 120

Number of people who are 35-55 years of age or like crunchicles = 121 + 120 - 19

The probability that the selected consumer is 35–55 years old or likes Crunchicles = 222/500 = 0.444.
