It’s 1/8 I don’t feel like explaining it but trust me
8x+12+12x+8
20x+20
The final answer is 20x+20
Answer:
n = 66 (to the nearest whole number)
66 randomly selected players must be surveyed
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
x+/-M.E
M.E = zr/√n
Making n the subject of formula;
n = (zr/M.E)^2 ........1
Given that;
Mean = x
Standard deviation r = 2.7 inches
Number of samples = n
Confidence interval = 95%
z(at 95% confidence) = 1.96
Margin of error M.E = 0.65 inches
Substituting the given values into equation 1;
n = (zr/M.E)^2
n = (1.96×2.7/0.65)^2
n = 66.28464852071
n = 66 (to the nearest whole number)
66 randomly selected players must be surveyed
Ok, so if a zero is at r1, then a factor is (x-r1)
since there are no other roots, it must be only taht root
3rd degree so reaise it to the 3rd power
(x-r1)³
and the root is at x=-3
(x-(-3))³
(x+3)³
answer is f(x)=(x+3)³
also could be x³+27 where it factors to one real root and 2 complex roots

Idk maybe the last one
