Answer:
True
Step-by-step explanation:
The application of an indirect proof is seen whenever we make assumptions about a given condition/statement. i.e. assuming what we are about to proof is false before proving it to be true

ava gathered data about the age of runners and the time it took them to complete a 5K race and half marathon. Her data is displayed in the given scatter plots
Based on the information provided by the table, it can be inferred that Running the half marathon took more than double the time than running the 5K. (option C)
How to read the graph?The graphs shown relate the time and age of athletes who ran 5k and half marathon.
The first graph shows the relationship in 5k, in which all the athletes, regardless of their age, managed to complete the test between 20 and 30 minutes.
The second graph shows the relationship in the half marathon, in which the younger runners completed the test in less time (80 minutes) than the older athletes (140 minutes).
According to this information, it can be inferred that the athletes took more than twice the time used in the 5k race to complete the half marathon (option C)

Rewrite this expression without using absolute value
I nEeD hElP qUiCk!
Answer:
Step-by-step explanation:
Normally when you are doing an absolute value question, you do it like this
y = abs(4x - 12) and you write the absolute value equation as
y = 4x - 12 and
y = - 4x + 12
These two are shown in graph27a
to show both wings of the absolute value curve
This is slightly different.
I think you would write this as
y = 4x - 12 {r <3} where the restriction is outside the equation written with curly brackets. You should see both graphs together. The discussion of r<3 is shown in graph 27b

The rectangle below has an area of 15k4 +35k3+20k2
What is the width and length
Answer:
the answer is 5
Step-by-step explanation:
it is right jk
Answer:
Step-by-step explanation:
We know area of a rectangle is xy where x and y are its dimensions.
A=xy
If we factor the area we will get the dimensions.
A=15k^4+35k^3+20k^2
(this can be factored in many ways to produce the same area, the answer choices you are given can be any given combination of factors.)
A=15k^4+15k^3+20k^3+20k^2
A=15k^3(k+1)+20k^2(k+1)
A=(15k^3+20k^2)(k+1) (this is one way)
A=5k(3k^2+4k)(k+1)
A=(3k^2+4k)(5k^2+5k) (and another way)
Either expression would give you width and length (or length and width) as they all produce the area of the original equation.

Colin predicted whether he got answers right or wrong in his 50 question exam.
He identified the 12 questions he thought he got wrong.
It turns out that Colin got 5 questions right that he thought he got wrong.
Colin also got a total score of 42 out of 50 in the test.
What is the percentage accuracy he had with predicting his scores
Answer:
92.86%
Step-by-step explanation:
Total questions, T = 50.
Colin thought 8 questions were right.
Colin got 5 questions right that he thought he got wrong.
Total score, s = 45.
So, actual number of questions which are wrong are 5.
Score according to him = 50 - 8 = 42.
Now, we know percentage accuracy is given by :
Therefore, percentage accuracy he had with predicting his scores is 92.86%.

V = area of base (A) × height
Here V = 216 cm³ and h = 12 cm , then
A × 12 = 216 ( divide both sides by 12 )

Write the equation of the line that passes through the points (1,-4) and (4, -5).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line
Answer:
[tex]y+4 = -\frac{1}{3} (x-1)[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope. Substitute the x and y values of the given points into the formula and solve:
[tex]m = \frac{(-5)-(-4)}{(4)-(1)} \\m = \frac{-5+4}{4-1} \\m = \frac{-1}{3}[/tex]
So, the slope is [tex]-\frac{1}{3}[/tex].
2) Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] into the formula.
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{1}{3}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line, choose any one of the given points (it doesn't matter which one) and substitute the x and y values of it into the formula. (I chose (1,-4), as seen below). This gives the equation of the line in point-slope form.
[tex]y-(-4) = -\frac{1}{3} (x-(1))\\y+4 = -\frac{1}{3} (x-1)[/tex]

Step-by-step explanation:
