Answer:
x= -1/2
Step-by-step explanation:
We have that
<span>y=3x</span>²<span>+18x-21
using a graph tool
see the attached figure
the solutions are
x=-7x=1</span>
Mean is a form of average, and in order to find this we add up all the numbers then divide by the amount of numbers we have.
So, we have 5 numbers here. (8, 17, 9, 3, and 13)
8 + 17 + 9 + 3 + 13 = 50
50/5 = 10
The mean of those five numbers is 10.
