Answer:
48 feet
Step-by-step explanation:
The area around something is the perimeter and the formula for perimeter of a rectangle is:
P = 2( l + w )
You are given the perimeter and width in this problem, so you would do the inverse of everything in this problem.
108 = 2( l +6 )
108/2 = 54
54 - 6 = 48
l = 48
The length is 48 feet
Answer:
B. Amount Donovan spends on granola bars each day.
Step-by-step explanation:
B is the price of a granola bar, so 2B is the price of two granola bars. Donovan eats 2 granola bars each day, so if he buys them, he spends 2B per day on granola bars.
_____
<em>Comment on the problem wording</em>
Please be aware that the problem statement tells you only that he <em>eats</em> 2 granola bars each day. It does not tell you the relationship between Donovan's <em>eating</em> and Donvan's <em>spending</em>. The question asks about his <em>spending</em>, so there is insufficient information <u>unless we make the assumption they are directly related</u>.
Answer:
The number 2 for sure but i dont know the rest
Step-by-step explanation:
The margin of error is 0.137 and the confidence interval for the population proportion is (0.443, 0.717).
<h3>What is the margin of error(MOE)?</h3>
It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
We have:
n = 50, X = 29,
Estimate point p = 29/50 = 0.58
q = 1-p = 1-0.58 = 0.42
Z at 0.05/2 (95% confidence interval) = 1.96
After calculating:
MOE = 0.137
Confidence interval will be: (p - MOE, p+MOE)
= (0.58-0.137, 0.58+0.137)
= (0.443, 0.717)
Thus, the margin of error is 0.137 and the confidence interval for the population proportion is (0.443, 0.717).

Answer: $4110.8 (more likely - 95% sure) or $2,107 (less likely)
Step-by-step explanation: It could be $4110.8 because you have the take the total they made and subtract is from the cost of the toys ($7,230-$2,450=$4,780). Then you have to take the result of that and get 14% of it, then subtract that from the $4,780 amount. Then you get the final answer which is $4110.8.
<u />
However, it could also be $2,107 because the question itsn't that clear in the second sentence. It could be saying that $2,450 is the price of the toys (which is what I assumed above), or that it is the profit that the $2,450 (which I used below). I think that the above answer is more likely because if not then the first number would never be used. Anyways here is the second way it could be.
Step-by-step explanation: It could be $2,107 because you take the profit ($2,450) and get 14% of it, then subtract that from the $2,450 amount. Then you get the final answer which is $2,107.
If I was you, I would do the first one ($4110.8) because I really think it is that one. I just put the other one here just in case.
