Answer:
%12.5
Step-by-step explanation:
<em>Step 1: Make an equation</em>
<em>400x = 450</em>
<u>Step 2: Divide both sides by 400</u>
400x / 400 = 450 / 400
<em>x = 1.125</em>
<u>Step 3: Convert into a percentage</u>
1.125 * 100
<em>%112.5</em>
<em>The increase is %12.5</em>
Answer: %12.5
The mean is the average.
To find the mean, you add up all the numbers, and then divide by the number of numbers.

<h3>
Answer: 24/25</h3>
====================================================
Explanation:
If sin(x) = 3/5, then cos(x) = 4/5 through the use of the trig identity
sin^2(x) + cos^2(x) = 1
This is assuming that x is in quadrant Q1.
Plug those values into the identity below and simplify.
sin(2x) = 2*sin(x)*cos(x)
sin(2x) = 2*(3/5)*(4/5)
sin(2x) = 24/25
