Answer:
Step-by-step explanation:
First off, we are given a parabola by definition:
Since , our parabola has an upward opening.
Should we think about it graphically, it will be no wonder that we should pay our attention to the points of the parabola intersecting the abscissa axis. In other words, we need our vertex to intersect the x axis only once per se.
The vertex:
As a result, our is parametric. suits us because . If , we do not have any roots at all. We have two roots if .
27+70+62+80=239
239÷5=47.8
47.8 is your final answer.
Answer:
The probability that Justin will practice soccer this evening is 16%.
Step-by-step explanation:
The probability that John will practice soccer is given by the product of the probability that it won't snow and the probability that he'll practice soccer. This is shown below:

practice soccer = 0.4*0.4
practice soccer = 0.16
The probability that Justin will practice soccer this evening is 16%,
