Answer:
w = 5
Step-by-step explanation:
Combining like terms is a very important part to this equation!
<em>5.2w - 1.4 = 3.2w + 8.6</em>
<em>I added 1.4 to the right side first, though you must do it to the left side of the equation as well</em>
<em>5.2w - 1.4 + (1.4) = 3.2w + 8.6 + (1.4)</em>
<em>5.2w = 3.2w + 10</em>
<em>Combine the remaining like terms. I subtracted 3.2w from both sides. </em>
<em>5.2w + (-3.2w) = 3.2w + (-3.2) +10</em>
<em>2w = 10</em>
<em>Now divide</em>
<em>2w = 10</em>
<em>w = </em><em />
<em>w = 5</em>

<span>Expected value is the sum of the probability of each even times the outcome of the event.
So she wins $10 with probability 2/8, $3 with probability 1/8, $0 with probability 3/8, and loses $3 with probability 2/8.
So,
E = 10(2/8) + 3(1/8) + 0(3/8) - 3(2/8)
=5/4 + 3/8 - 3/4
=7/4

Answer: 42
Step-by-step explanation:
Here given numbers : 28 and 63
so Mean = √x * y
let x = 28 and y = 63
<em>So mean proportion between them is:</em>
M = √63 * 28
M = √1764
M = 42
- therefore the mean proportion between 28 and 63 is 42

The property displayed here is the distributive property.
If you have a variable or unknown number inside or outside of parentheses, you can distribute it to each term and add the terms together, and it will remain true.
Example:
4(x + 5)
After distributing, it'll look like this:
4x + 20
Check the picture below, that enclosed area is pretty much our "washer".
now, to get the outer radius, or "farther" radius from the axis of rotation, what I usually do is, use the f(x) - g(x) to get the area under the curve, using the axis of rotation for g(x).
