<span>c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>
Each hiker owes $41 or 4100 cents for the hiking trip.
<u><em>Explanation</em></u>
Cost of each permit is $15. So, the cost of <u>two permits</u> will be: 
Cost of each tram ticket is $19. So, the cost of <u>three tickets</u> will be: 
Cost of <u>one can</u> of bear spray is $36.
So, the total cost of the hiking trip 
As the <u>three hikers</u> are dividing the total costs of the trip <u>evenly</u>, so each hiker owes 
or 4100 cents.
1 gallon = 128 oz
128/6= 21.33 cups
4x21.33= 85 cups
Please write x^2, not x2.
If you stretch the graph of y=x^2 vertically by a factor of 4, the resulting graph represents the quadratic function y = 4x^2. It's still a parabola, but appears to be thinner.
This particular question is about horizontal stretching, however. Stretching the graph horizontally by a factor of 4 results in the new function g(x) = (x/4)^2. Try graphing x^2 and also (x/4)^2 on the same set of axes to observe this phenomenon.
Answer:
Since there is a curve, I believe it is a function.
