Answer:
6x + 14y + 13
Step-by-step explanation:
combine the like terms.
(5+8), (2y + 12y), and 6x which will be dealt with after solving.
13 + 14y + 6x. And that is it because there are no more like terms to be put together.

Answer:
Step-by-step explanation:
The formula to calculate the surface area of a sphere is the following:
Where A is the area of the sphere and r is the radius of the sphere.
In this case we know that the diameter d of the sphere is:
The diameter is:
.
Thus
Then the surface area of the sphere is:
P = 2(l+w)
substitute for P and l
12+8y = 2 (4x-2y+w)
distribute
12+8y = 8x -4y +2w
solve for w
subtract 8x from each side
12 +8y -8x = -4y+2w
add 4y to each side
12 +12 y -8x = 2w
divide by2
6 +6y-4x =w
the other side is 6+6y-4x
Answer:
B. The value is a parameter because the career at-bats of a baseball player are a population.
Step-by-step explanation:
The hitter had a career batting average of 0.366.
This value comes from information about the population of every time he has ever gone up to bat. Therefore, it is a parameter.
If on the other hand, we take the batting average of 5 games, the 5 games will be a sample and the batting average will be a statistic.
