Answer:
4.66
Step-by-step explanation:
We are given the following data
26, 26, 21, 22, 20, 25, 35
Step 1
We find the Mean
Mean = 26+ 26+ 21+ 22+20+25+ 35/7
= 175/7
= 25
Step 2
We find the Standard Deviation
The formula for Standard deviation that we would use is the Population Standard deviation, this is because the data given above is the data of the number of pounds of trash collected by each teenager
= √(x - Mean)²/n
= √(26 - 25)²+( 26 - 25)²+ (21 - 25)²+ (22 - 25)² +(20 - 25)²+(25 - 25)²+ (35 - 25)²/7
= √152/7
= √21.7142857
= 4.65985898
Approximately = 4.66

Answer:
yes
Step-by-step explanation:
The other factor is (x+5), so the product is ...
(x^4 -1)(x +5) = x^5 +5x^4 -x -5 = P(x)
(x^4 -1) is a factor of P(x).
_____
It is not a <em>primitive</em> factor, because it can be factored as ...
x^4 -1 = (x^2 -1)(x^2 +1) = (x -1)(x +1)(x^2 +1)
The complete factorization of P(x) to real numbers is ...
P(x) = (x -1)(x +1)(x +5)(x^2 +1)
