Well to find the mean you need to add up the total number of people and then divide by the total number of days meaning if there is a total of 105 people, you would divide that by 5 and get 21
13 + 23 + 24 + 31 + 14 = 105
105 / 5 = 21

Step-by-step explanation:
Answer:
x > -2
Step-by-step explanation:
14 <-7x
or, 14/-7=-7x/-7
or, -2 < x
Solving a quadratic function, it is found that the ball has a height of 19 feet at t = 0.72 seconds and t = 1.22 seconds.
<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:

The solutions are:
In which:

In this problem, the function is:
h(t) = -16t² + 31t + 5
The height is of 19 feet when h(t) = 19, hence:
19 = -16t² + 31t + 5
16t² - 31t + 14 = 0.
