Answer:
A probability must be between zero and one.
Step-by-step explanation:
Probability is the chance of something occuring. 120% is not realistic in real world examples, because the probability standard ranges from "definitely will not happen" to "definitely will happen", meaning a 0% chance of it occurring to 100% chance of it occurring. The only time 100.0%+ will be applicable are typically in simulations, which allows for such to counterbalance any negatives percentages that is allocated to the target. However, in the real world, it will never go over 100%.
The graph of y = x2 –7x +12 is a parabola with x-intercepts at and a vertex that is the
point on the curve.
The vertex of the parabola is at the point (3.5, 0.75).
To find the x-intercepts of the given quadratic equation [tex]y = x^2 - 7x + 12,[/tex]we set y = 0 and solve for x.
[tex]0 = x^2 - 7x + 12[/tex]
Factoring the quadratic equation, we can rewrite it as:
0 = (x - 3)(x - 4)
Setting each factor equal to zero, we find the x-intercepts:
x - 3 = 0 => x = 3
x - 4 = 0 => x = 4
Therefore, the parabola represented by the equation [tex]y = x^2 - 7x + 12[/tex] has x-intercepts at x = 3 and x = 4.
To find the vertex of the parabola, we can use the formula:
x = -b / (2a)
In this case, a = 1 (coefficient of [tex]x^2[/tex]) and b = -7 (coefficient of x). Plugging these values into the formula, we get:
x = -(-7) / (2[tex]\times[/tex] 1)
x = 7 / 2
x = 3.5
To find the y-coordinate of the vertex, we substitute this value back into the original equation:
[tex]y = (3.5)^2 - 7(3.5) + 12[/tex]
y = 12.25 - 24.5 + 12
y = 0.75
Therefore, the vertex of the parabola is at the point (3.5, 0.75).
In summary, the graph of the equation [tex]y = x^2 - 7x + 12[/tex]is a parabola with x-intercepts at x = 3 and x = 4. The vertex of the parabola is located at the point (3.5, 0.75).

What is the slope of the line shown below
Answer:
Option:C 2/3
Equation= y=2/3x-5
Answer:
2/3
Step-by-step explanation:
to find slope m, use this method
m=(y2-y1)/(z2-x1)
therefore m=(1-(-7))/((9-(-3))
m=8/12.

-7.2x < -50.4x + 432
Answer:
x<10
Step-by-step explanation:
We can start off with adding 50.4x to both sides:
Once we do that we get the following: 43.2x < 432
If you notice, they both are almost the same number with the different of the decimal place. Lets multiply both sides by 10 to get rid of the decimal place:
432x < 4320
Now, if you see, they're basically the same number but the second place is x10 greater.
We can divide both sides by 432 and get x<10 as our answer!

Write the slope-intercept form of the equation for each line.
Step-by-step explanation:
First, let's find the slope of the line. Note that it passes through P1(-8, -1) and P2(0, -5). So the slope of this line is
[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-5 - (-1)}{0 - (-8)}[/tex]
[tex]\:\:\:\:\:= \dfrac{-4}{8} = -\dfrac{1}{2}[/tex]
The slope-intercept form of the equation can be written as
[tex]y = mx + b = -\frac{1}{2}x + b[/tex]
To solve for b, we can use either P1 or P2. Let's use P2.
[tex]-5 = -\frac{1}{2}(0) + b \Rightarrow b = -5[/tex]
Therefore, the slope-intercept form of the equation for the line is given by
[tex]y = -\frac{1}{2}x - 5[/tex]
Luis rents a 17-foot moving truck for 3 days. The rate for the truck is $60 for the
first day and $21.95 for each day after that. He also has to pay $0.79 per mile for
every mile over 50 miles. Luis also purchases insurance which cost him $20. If Luis
drives 200 miles before he returns the truck, how much will he pay?
$242.40
$204.35
$222.40
$281.90.
Answer:
Luis will pay $242.40
Step-by-step explanation:
60.00(1st day)+21.95(2nd day)+21.95(3rd day)+20.00(Insurance)=123.90
200 (mi driven) - 50 (mi allowed)= 150 miles must be paid for
150*0.79(rate per mile)=118.50
123.90+118.50=$242.40 Total Cost

Step-by-step explanation:
u did the butterfly method so just multiply across & divide so 95 • 9 = 855 and 450 • x = 450x
so 450x = 855
now isolate the variable so divide 450 on both sides
855 ÷ 450 = 1.9

Identify the vertex of the parabola.
A. (4,3)
B. (2,7)
C. (3,4)
D. (6,7)
Answer:
A. (4,3)
Step-by-step explanation:
The vertex of a parabola is the maximum or minimum point on the graph of the quadratic function aka where you just have "one value" wether than be the very top, the very bottom, etc
In summary:
Here we can see it'll be the very bottom as the parabola is angled upwards.
Looking at the graph, we can see it is 4 units to the right and 3 units up.
The first number is the x, or the right/left, so our first number is 4
The second number is our y, or the up/down, so our second number is 3
This leaves us with the point (4, 3) and an answer of A!

Homer Simpson finds himself in a panic attempting to meet the April 15th tax deadline. If Homer and his wife have an income of $60,000, earned $1200 in interest, invested $2500 in a tax-deferred savings plan, and have a total of $12,000 in exemptions and deductions, what would be his taxable income?
Answer:
As given, Income of Homer and his wife = $60000
Interest earned = $1200.
Adding this to total income, we have total taxable amount = 60000+1200 = $61200
Now, investment in tax deferred savings plan = $ 2500
This amount will be subtracted from total taxable income, so amount becomes = 61200-2500 = $58700
We will also subtract the exemptions and deductions = $12000
Amount becomes = 58700-12000 = $46700
Hence, Net taxable income is $46,700

A poster is 1 3/5 feet wide and 3 1/8 feet long. What is the area of the poster?
Answer:
5 feet squared.
Step-by-step explanation:
You can multiply the length by the width to get the total area of the poster.
1 3/5 x 3 1/8 is equal to 5, therefore, the area of the poster is 5 feet squared.
Answer: 5 ft^2
Step-by-step explanation:
Area=length times width. In this problem, the lenght is 3 1/8 and the width is 1 3/5. We have to multiply these two:
1 3/5*3 1/8= 8/5*25/8=5.
So the area is 5 ft^2.
