Answer:
(8x + 20)-2x
Step-by-step explanation:
We don't know what x is, so we use the Distributive Property to do 4 x 2x, then 4x5. We put parentheses around it, and then do - 2x
Answer:
X=37.6 because the 90 degree angle plus the 52.4 equals 142.4 the subtract that from 180 then ta da.
Answer:
The error bound is of 13.5 corn kernels.
Step-by-step explanation:
Any confidence interval has a lower bound and an upper bound. The error bound is the difference between the values of those two bounds, divided by 2.
In this problem, we have that:
Lower bound: 858.50
Upper bound: 885.50
Error bound: (885.50-858.50)/2 = 13.5
The error bound is of 13.5 corn kernels.
