1) Marnie pays $0.06 per kilowatt-hour of electricity.
2)Marnie budgeted $72 for her electricity.
3)You are supposed to find the greatest number of kilowatt-hours Marnie can use and stay within her budget of $72.
A = 1/2 (2+7)(1.5)
A = 4.5 (1.5)
A = 6.75 yd^2
Answer:
The margin of error of his experiment is of 0.1074.
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 z-score that has a p-value of 
.
The margin of error is of:
30 M & M's from a bag, and 3 of them are green.
This means that 
Standard 95% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
Margin of error:
The margin of error of his experiment is of 0.1074.
Answer:
It may be A. or C.
Step-by-step explanation:
A. 5 = 20 4 = 16 4 = 16 20 + 16 = 36 + 16 = 52
B. 3 = 12 3 = 12 7 = 27 + 12 = 39 + 12 = 51
i uhhh don't know this is confusing
im very sorry if im incorrect
I hope that you are meaning: Algebraic Expression
