Answer: [tex]-2x^2 + 10x-8[/tex]
Step-by-step explanation:
To find the product of the binomials, we first need to find the linear equations for the lines.
Using the rise over run method for f(x), we can see that the line rises 2 units for every 1 unit ran. 2/1 = 2, so we know the slope is 2, and we can see that the y-intercept on the graph is -2.
Equation: [tex]f(x) = 2x-2[/tex]
Using the rise over run method for g(x), we can see that the line rises -1 unit for every 1 unit ran. -1/1 = -1, so we know the slope is -1, and we can see that the y-intercept on the graph is 4.
Equation: [tex]g(x) = -x+4[/tex]
Multiplying the binomials:
[tex](2x-2)(-x+4)[/tex]
Use the FOIL method:
First: 2x * -x
Outside: 2x * 4
Inside: -2 * -x
Last: -2 * + 4
[tex]-2x^2+8x+2x-8\\\\-2x^2 + 10x-8[/tex]
You and some friends buy tickets to a raffle at your school. You can each buy one ticket. In total 150 tickets were sold. The probability that on of your friends win the raffle is 1/30. How many friends of yours bought tickets
Answer:5
Step-by-step explanation:
Given
There are total of 150 ticket
If the probability to win a raffle is [tex]\frac{1}{30}[/tex]
[tex]Probability =\frac{\text{Favorable outvome }}{\text{Total outcome}}[/tex]
[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{\text{Total no of tickets}}[/tex]
[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{150}[/tex]
no of tickets bought[tex]=\frac{150}{30}=5[/tex]
and no of tickets bought=No of friends
Therefore there 5 persons who bought tickets

What are the Tree Numbers
Answer:
679.
Step-by-step explanation:
There is either a 1, 4 or 7 in the number.
From the second guess, 189, 1 cannot be in the number , either 8 or 9 are in right place. Also 4 or 7 are in the number.
9 6 4: 9 may be in the number, also 4 or 6.
No 2,3 or 5.
2 8 6 this tells us there is no 8 , and 9 is the last digit.
As there is no 2 there must be a 6 in the number
So the number contains a 9 and a 6.
The third number is either a 4 or a 7, but from the 964 result it cannot be a 4 because 6 is included.
So it either 679 or 769.
But 964 had 6 in the wrong place so the number is 679.
I think the answer is 679 because you every numbers make sense except for 679.

What is the absolute deviation of Victoria’s quiz score from the mean?
A. 0 points
B. 2 points
C. −1 point
D. 1 point
Please give the right answer
Answer:
B. 2 points(Approximately)
Step-by-step explanation:
The mean absolute deviation (MAD) is defined as
[tex]MAD=\frac{\Sigma |x_{i}-\mu| }{N}[/tex]
Where [tex]\mu[/tex] is the means and [tex]N[/tex] is the total number of elements.
First, we need to find the mean:
[tex]\mu = \frac{\Sigma x_{i} }{N} =\frac{18+12+15+10+13+20+16+12+18+6}{10}= \frac{140}{10}\\ \mu=14[/tex]
Then, we calculate the difference between each value and the mean, from that difference, we are gonna use the absolute value.
18 - 14 = |4|
12 - 14 = |-2|
15 - 14 = |-1|
10 - 14 = |-4|
13 - 14 = |-1|
20 - 14 = |6|
16 - 14 = |2|
12 - 14 = |-2|
18 - 14 = |4|
6 - 14 = |-8|
Now, we sum all terms and divide them by the total number of elements, which are 14.
[tex]MAD=\frac{4+2+1+4+1+6+2+2+4+8}{14}= \frac{34}{14}\\ MAD \approx 2.4[/tex]
Therefore, the absolute deviation is about 2 points. The right answer is B.

A circle has a radius of 5 in. A central angle that measures 150° cuts off an arc.
Explain how to find the arc length exactly, and then approximate it to one decimal place.
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in

What is Equation of line?
The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Some graph are shown in figure.
Now, Find the best fit of the line as;
In option A;
The line is contain almost near to the points of the graph.
So, This is the best example of a line of best fit.
In option B;
The line is not passes through any of the given points.
So, It is not best fit.
In option C;
The line is perpendicular to the graph of the points.
So, It is not best fit.
In option D;
The line is vertically with the points of the graph.
So, It is not best fit.
Thus, The best example of a line of best fit will be given in option A.

C
x ≥ -7.8
D
x ≤ 7.8
Answer
The answer is B
Step-by-step explanation:
Its correct
Answer:
The answer is B.
Step-by-step explanation:
In order to solve x, you have to make x the subject by substracting 11.6 to both sides:
[tex]11.6 + x \geqslant 4.8[/tex]
[tex]11.6 + x - 11.6 \geqslant 4.8 - 11.6[/tex]
