Put the values you know in the formula and solve for the constant of variation.
.. y = kx^2
.. k = y/x^2 . . . . . fill in values for y and x and compute.
Answer:
$92
Step-by-step explanation:
Since Sally plans to keep the kayak for 6 hours and it's $7 per hour we can multiply 6*7 to determine how much she will be charged for keeping the kayak.
6*7=$42
Now we add this to the original deposit of $50.
$50+$42=$92
The answer is 271.04 because you have to do 242 times .12 then add your answer to 242.
Answer:
Step-by-step explanation:
We are given the following in the question:
Significance level = 0.01
Width of interval = 0.1
Population variance = 
We have to find the sample size so that the width of the confidence interval is no larger than 0.1

Formula for sample size:

where E is the margin of error. Since the confidence interval width is 0.1,

Putting these values in the equation:

So, the above expression helps us to calculate the sample size so that the width of the confidence interval is no larger than 0.1 for different sample variances.
