Look at some shorter periods of time to decide whether their reasonable. Do that by simplifying the fraction. . . . . 40,000 pounds / 80 years = 4,000 pounds / 8 years = 2,000 pounds (1 ton) / 4 years = 1,000 pounds / 2 years (have you decided yet ? Well, simplify it some more) 1,000 pounds / 2 years = 500 pounds per year = almost 1 and 1/2 pounds of bread every day of your life. NOW what do you think ? Make sense ?

Plug in the standard deviation formula. This is new to me but it took some research.. Hope it helps
Answer:
She probably was supposed to multiply, instead of add.
Step-by-step explanation:
First multiply 24 and 32, which is 768.
Second multiply 768 and 12, which is 9216
9216 is the answer.
Answer:
Equation of function, y = (x-1)²
Step-by-step explanation:
The general formula of a parabola symmetric about x - axis is given by (x-h)²=4a(y-k), where (h,k) is the vertex.
Here (h, k) = (1,0)
So, we have (x-1)²=4a(y-0)
(x-1)²=4ay
One point on the parabola is (0,1) since y intercept is 1.
Substituting
(0-1)²=4 x a x 1
1 = 4 a
Equation of parabola,
Equation of function, y = (x-1)²
