Answer: The answer is D
because x^2^4 power is x^8 and x^2*x^2*x^2*x^2 which is 2+2+2+2 which is x^8
Step-by-step explanation:
it is not C because it would be 4(c^2) which is 4x^2
it is not A because (x^2)(x^4) is 2+4 which is 6 so that means it would be x^6
It would be price a, price c, price b because to find the unit rate you divide like: 3.87/3.
i might be wrong tho! i haven't done this in a while! lol
Answer:
(x,y) = (2,3)
Step-by-step explanation:
Solving steps:
2y = 6 (Divide both sides)
y = 3 (Substitute the value of y)
2x - 3 = 1 (Solve the equation)
x = 2
(x,y) = (2,3)
Hope this helped!!!
Answer:
The 99% confidence interval for the proportion of the population who are obese is (0.25, 0.282)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
99% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval for the proportion of the population who are obese is (0.25, 0.282)
