Answer: The mean of the data set is 25.
Step-by-step explanation:
To calculate the mean of a data set, first add up all the values.
17 + 34 + 19 + 27 + 30 + 23 = 150
Then divide the sum by the amount of values in the data set. Our sum here is 150 and the amount of data values is 6.
150 ÷ 6 = 25
Answer:
the ball is in the air for 8 seconds
Step-by-step explanation:
f(x) = y
when y = 0, the ball would've travelled through the air over the final time of flight.
0 = -5x^2 + 40x + 0
use quadratic equation to find the value of x
x = (-b ± √b^2 - 4 • a • c) / 2 • a
x = (-40 ± √40^2 - 4 • -5 • 0) / 2 • -5
x = (-40 ± √1600) / - 10
x = (-40 ± 40) / - 10
x = 0 or x = 8
