Answer:
M = 6.50n
Step-by-step explanation:
since it is per child, it will be multiplied by the amount of children, n. Therefore giving us the cost of M, or the equivalent.
You multiply Q and a to get 240, because 15 x 16 = 240.
Well, I know to find the mean you add all the numbers and divide it by how many numbers there were, so I'm guessing you just do that with the stem and leaf plot. I hoped this helped a bit
5x^2
6x^3y
2x^3 3xy
^ means the little number above x eg x^3
Because both answers equal y, we can set them equal to each other. So, -8x=-5x-9. Add five over to get -3x=-9. Divide and x=3. Then plug 3 in to solve for y. -8(3)=24. The ordered pair is (3,24).
