Step-by-step explanation:

2x^2 + 8x + 3 is your final answer.
I’m pretty sure c is the right answer
I believe the answer is y = -3x + 15
This is what I got from calculating it but I haven’t done this type of equation in a while
Answer: 30.2
Explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:
186
6
=
31
And we can do the same for the men:
116
4
=
29
And now we can combine the sum and count of the men and women to find the mean for the office:
186
+
116
10
=
302
10
=
30.2
