Question:
Given a polynomial f(x), if (x − 4) is a factor, what else must be true?
f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0_______________________________________
Solution:
f(x) is a polynomial.
(x - 4) is a polynomial of f(x).
By converse of factor theorem: If (x - a) is a factor of f(x), then, f(a) = 0.
On comparing (x - 4) with (x - a), we get,
a = 4So,
f(a) = 0
=> f(4) = 0

Cam hit the bull's-eye in darts 8 times out of 15 throws. What is the experimental probability that cam's next throw will hit the bull's-eye?
Answer:
[tex]Probability = 0.533[/tex]
Step-by-step explanation:
Given
[tex]Hits = 8[/tex]
[tex]Throws = 15[/tex]
Required
Determine the experimental probability
This is calculated by dividing the number of hits by the total throws.
[tex]Probability = \frac{Hits}{Throws}[/tex]
[tex]Probability = \frac{8}{15}[/tex]
[tex]Probability = 0.533[/tex]

he
Answer:
Third Quadrant
Step-by-step explanation:
1st Quadrant: All are positive
2nd Quadrant: Only sin is positive
3rd Quadrant: Only tan is positive
4th quadrant: Only cos is positive
In the third quadrant, the value of both sine and cosine trigonometric functions will be negative.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The Quadrant in which both cosine and sine value is negative will be

What is the decimal multiplier to increase by 6.1%?
first add or subtract the percentage from 100 ,then convert to a decimal.
What is a simple definition of the multiplier?
It is the number of times a rise in national income exceeds the rise in injections of demand that caused it.
What is the multiplier process?
The multiplier effect comes about because injections of new demand for goods and services into the circular flow of income stimulate further rounds of spending – in other words “one person’s spending is another’s income”
This can lead to a bigger eventual final effect on output and employment.

$9,800,000 is what percent of $7,000,000
Answer:
686000000000
Step-by-step explanation:
1. We assume, that the number 7000000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 7000000 is 100%, so we can write it down as 7000000=100%.
4. We know, that x is 9800000% of the output value, so we can write it down as x=9800000%.
5. Now we have two simple equations:
1) 7000000=100%
2) x=9800000%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
7000000/x=100%/9800000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 9800000% of 7000000
7000000/x=100/9800000
(7000000/x)*x=(100/9800000)*x - we multiply both sides of the equation by x
7000000=1.0204081632653E-5*x - we divide both sides of the equation by (1.0204081632653E-5) to get x
7000000/1.0204081632653E-5=x
686000000000=x
x=686000000000
now we have:
9800000% of 7000000=686000000000

Factor the equation. [tex]x^2-6x+8[/tex]
You can't factor it.
Answer:
(x - 2)(x - 4)
Step-by-step explanation:
Given
x² - 6x + 8
Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (- 6)
The factors are - 2 and - 4, since
- 2 × - 4 = + 8 and - 2 - 4 = - 6, then
x² - 6x + 8 = (x - 2)x - 4) ← in factored form
A teacher has two large containers filled with blue, red, and green beads, and claims the proportions of red beads are the same in each container. Each student shakes the first container, selects 50 beads, counts the number of red beads, and returns the beads to the container. The student repeats this process for the second container. One student’s samples contained 13 red beads from the first container and 16 red beads from the second container.
Based on the 95% confidence interval, (–0.24, 0.11), is the teacher’s claim justified?
The teacher’s claim is not justified because the two sample proportions are different.
The teacher’s claim is not justified because the interval contains both positive and negative values.
The teacher’s claim is justified because the interval contains 0, meaning there is no difference in the proportions of beads in each container.
The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
Answer:
D. The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
Explanation:
100%
Answer: The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.

The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.

What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.
