with exponent 5
Thus the polynomial is of degree 5 → D
Hello!
First you can distribute the 3
4 + 6r + 6s + 3r
Then you combine like terms
4 + 9r + 6s
The answer is 9r + 6s + 4
Hope this helps!
Answer:
sod- 1662.6
fencing- 807.6
all- 2470.2
Step-by-step explanation:
sod-
25.5 * 8.25 = 207.825
207.825*8= 1662.6
fencing-
8.25+8.25+25.5+25.5= 67.3
67.3*12= 807.6
fencing + sod
1662.6 + 807.6= 2470.2
I think the correct answer from the choices listed above is the third option. <span>If a statistic used to estimate a parameter is such that the mean of its sampling distribution is equal to the actual value of the parameter, then it is a biased estimator. Hope this answers the question.
