I'm not good at math but I think is 3f because you'll be multiplying f(unknown #) by 3 so f(x) would be 3f
Answer:
A
Step-by-step explanation:
The zeros of a polynomial function are found by factoring in the form
a(x - r1)(x - r2)(x - r3) ... = 0, where each 'r-something' is a root (or solution) and 'a' is the leading coefficient.
Like if we have 3x² - 3x - 6 = 0
Factoring it as 3(x-2)(x + 1) = 0 shows the roots are 2 and -1.
And sine the right side is zero, we can even drop the factor of 3 on the left, and still have an equivalent equation (has same answers).
(x-2)(x + 1) = 0
The reason this works is because each factor in parentheses adds up to zero, creating a factor of zero in what is being multiplied on the left. And we know that if you have a series of factors in a product, and any one of those factors is zero, the whole product must be zero. So what is on the left equals the zero on the right, making the equation true.
For the answer to the question above,
The expected value in percentage format is 0.2 x 15+0.4 x 20 + 0.3 x 30 + 0.1*35 = <u><em>23.5%</em></u>
The answer is <u><em>23.5%
</em></u>
I hope my answer helped you. Have a nice day ahead!

Volume of a Cylinder Formula: V = πr²h
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>r</em> = 13 in
<em>h</em> = 30 in
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cylinder Formula]: V = π(13 in)²(30 in)
- Evaluate exponents: V = π(169 in²)(30 in)
- Multiply: V = 5070π in³
