Answer:
The parameter is the population proportion of fans who listened to her new single and has an estimated value of 90%.
Step-by-step explanation:
The parameter is a value that corresponds to a population, while an a value that corresponds to a sample is know as statistic.
She takes a sample to estimate, with a point estimate and probably with a confidence interval around this point estimate, the true proportion of fans who listened to her new single.
This is the paramater: the population proportion of fans who listened to her new single.
Its value comes from an estimation based on the sample proportion (point estimate).
The sample proportion is 90%, so we can estimate, as there is no bias, that the population proportion is also 90%.
Remember
(x^m)^n=x^(mn)
and
(x^m)(x^n)=x^(m+n)
and
(x^m)/(x^n)=x^(m-n)
so
(4^2)^3=4^(2*3)=4^6
notice
4^6=(2^2)^6=2^2*6)=2^12
(4/2)^3=2^3
on top we have
(2^12)(2^3)(2^3)=2^(12+3+3)=2^18
on bottom
8^3
conver to base 2
(2^3)^3=2^(3*3)=2^9
now we have
(2^18)/(2^9)=2^(18-9)=2^9
Answer:
Neither function A nor function B has an x-intercept.
Step-by-step explanation:
Function A has a y-intercept at (0, 5).
Function B is defined for negative numbers as well as positive numbers, but not for x=0.
These observations eliminate all answer choices but the first one.
Your answer will be x2-2x-15
Answer:
156 different pairs will be there.
Step-by-step explanation:
As the order is essential as we need different pairs therefore permutations will be used.
A permutation is any ordered subset of the objects r selected with regard to their order, from the set of n distinct objects. It is given by nPr where n> r
Total number is 13 and required number is 2
n= 13 and r= 2
13 P2= 156 possible combinations.
A combination is any subset of the objects r selected without regard to their order, from the set of n distinct objects. It is given by nCr where n> r
