Answer:
The expected value is also known as the expectation, mathematical expectation, mean, average, or first moment.
Answer:
Given the expression: 3x10 − 48x2
Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)
<em>answer</em><em>:</em>
<em>3</em><em>x</em><em>²</em><em>(</em><em>x^8-16</em><em>)</em>
Part B: Factor the entire expression completely. Show the steps of your work.
3x²(x^8-16)
3x²((x^)²-4²)
3x²(x⁴+4)(x⁴-4)
3x²(x⁴+4)((x²)²-2²)
3x²(x⁴+4)(x²+2)(x²-2)
1/4(2x - 14) = 4
Divide by 1/4. (dividing by a fraction = multiplying by its reciprocal, so ÷1/4 = ×4)
2x - 14 = 16
Add 14 to each side.
2x = 30
Divide by 2.
x = 15
When you multiply a base with an exponent by a base with an exponent, you add the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(they have the same base of x)
(you can't combine the exponents because they have different bases of y and x)
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or 
or 
Add the exponents together
Make the exponent positive
