Answer:
that- y= 12/22x + 14, I think-
Step-by-step explanation:
sorry if its wrong- cuz it prolly iz but I tried-
Answer:
y = -3/8(x + 2)^2 + 8
Step-by-step explanation:
vertex form is
y = a(x - b)^2 + c where a is a constant and (b,c) is the vertex.
The maximum is at (-2, 8) because x 8 = height and x =-2 is equn. of symmetry
So here we have
y = a(x - (-2))^2 + 8
y = a(x + 2)^2 + 8
Now at the point (-6, 2):
2 = a(-6+2)^2 + 8
2 = 16a + 8
16a = -6
1 = -3/8.
So our equation is y = 3/8(x + 2)^2 + 8
Answer:
Emma can complete the calls alone in 6 days, which means she can complete
of the calls in one day. So, Emma’s rate per day is
. Jackson can complete the calls alone in
days, which means he can complete
of the calls in one day. So, Jackson’s rate per day is
. Because they’re working together, the time,
, is the same for both.
Multiply across the table to find the part of the task each has completed. Use the equation work completed = (rate)(time) to fill in the last column cells.

Answer:
True.
Step-by-step explanation:
If we have for a sample of size n=25 a sample variance of 400, the standard error can be written as:

This way of calculating the standard error is the same used for estimating the standard deviation of the sample means for samples of size n=25.
