Answer:
Number of person use more than 15 hours per week from 800 subscribers = 448
Step-by-step explanation:
Given:
Total number of sample = 50
Result = 28 Person use more than 15 hours per week
Find:
How many people use more than 15 hours per week
Computation:
⇒ Probability of Person use internet more than 15 hours per week = 28 / 50
⇒Probability of Person use internet more than 15 hours per week = 0.56
⇒Number of person use more than 15 hours per week from 800 subscribers = 800 × Probability of Person use internet more than 15 hours per week
⇒Number of person use more than 15 hours per week from 800 subscribers = 800 × 0.56
⇒ Number of person use more than 15 hours per week from 800 subscribers = 448
Answer: 20 tickets
Step-by-step explanation:
From the question, we are informed that Shelby sold 75 raffle tickets for the school fundraiser over a 3-year period while Kelly sold 15 less tickets than Shelby. This means that the number of tickets sold by Kelly is:
= 75 - 15
= 60 tickets
The number of tickets sold by Kelly each year on average will be:
= Number of tickets sold / Number of years.
= 60/3.
= 20 tickets
over the last 3 years
