Answer: C
Step-by-step explanation:
Answer:
C. 2x^4; E. -5x
Step-by-step explanation:
P(x) = x^3 − x − 2 and Q(x) = x^2 + 2x + 1
P(x) * Q(x) = (x^3 − x − 2)(x^2 + 2x + 1) =
= x^5 + 2x^4 + x^3 - x^3 - 2x^2 - x - 2x^2 - 4x - 2
= x^5 + 2x^4 - 4x^2 - 5x - 2

Answer:
Paired t test
Explanation:
The paired sample t test is used to measure or compare the mean of two observations or samples by measuring each subject two times as is seen above with the gold measurement which would result in two sets or pair of samples in a statistical procedure. We observe from the question that we measure each gold with two methods and then compare result of the two methods in terms of their mean error using the paired t test.
For Ramona to know how much she expects to pay for the carpet she is ordering, she first needs to know how many square foot the the room has.
In getting the area of the room, you multiply one side with the other,
in equation,
19.5 ft x 41.6 ft = 811.2 sq ft.
Then if the carpet costs $9.50 per sq ft, you simply multiply it the area of the room
in equation,
$9.50/ sq ft. x 811.2 sq ft, cancelling out the unit of sq ft
the answer would be $7,706.4
