Yes, the correct answer is option C
The reason is because angle 2 is equal to angle 4 but not angle 3. The reason angle 2 is equal to angle 4, is because they are congruent angles.
So, angle 2 = angle 3 is not correct because they are not congruent with each other.
I hope this explanation helps~
Option C is your answer
I believe that the question is asking which one is false (as all the other are true).
Angles 2 and 3 are not congruent, because they are next to each other (not vertical angles). Rather, they are supplementary angles, meaning they would add up to 180° in measurement.

A bag contains 10 green marbles and 4 yellow marbles. If two marbles are chosen at random, one at a time and without replacement, what is the probability of getting two green marbles?
Answers
P(2nd green), is 9/13 because there are only 9 green marbles and only 13 total marbles. Then you multiply them 5/7 x 9/13 = 35/117
Answer: The required probability of getting two green marbles is 49.45%.
Step-by-step explanation: Given that a bag contains 10 green marbles and 4 yellow marbles. Two marbles are chosen at random, one at a time and without replacement.
We are to find the probability of getting two green marbles.
Let S denote the sample space for the experiment of choosing a marble from the bag and A denote the event of getting a green marble.
The, n(S) = 10 + 4 = 14 and n(A) = 10.
So, the probability of event A will be
[tex]P(A)=\dfrac{n(A)}{n(S)}=\dfrac{10}{14}=\dfrac{5}{7}.[/tex]
After getting one green marble and not replacing, let S' denote the sample space for the experiment of choosing a marble from the bag
and
let B denote the event of getting another green marble.
Then, n(S') = 14 - 1 = 13 and n(B) = 10 - 1 = 9.
Then, the probability of getting two green marbles is given by
[tex]P\\\\=P(A)\times P(B)\\\\=\dfrac{5}{7}\times\dfrac{n(B)}{n(S')}\\\\\\=\dfrac{5}{7}\times\dfrac{9}{13}\\\\\\=\dfrac{45}{91}\times100\%\\\\=49.45\%.[/tex]
Thus, the required probability of getting two marbles is 49.45%.

The larger of two supplementary angles measures 20° less than four times the measures of the smaller angle .find the degree measure of each angle
Answers
From that knowledge we can write up some equations.
Let angle 1 = x, and angle 2 = y
x + y = 180
"The larger of two supplementary angles measures 20° less than four times the measure of the smaller angle"
(Let x be the larger angle)
x+20 = 4y
Since there are two different equations, and two variables, this means we have a set of simultaneous equations.
We can solve this via the substitution method or the elimination method.
I choose to solve it via the substitution method cause of personal preference.
x + y = 180 => x = 180- y
x+20 = 4y => x = 4y - 20
Make them equal each other..
180 - y = 4y - 20
200 = 5y
40 = y
Now that we know y we can sub it into any equation to find x
x + 20 = 4y
x + 20 = 4(40)
x + 20 = 160
x = 140
So the angles are 40° and 140°
We want to create a system of equations that allows us to find the values of two supplementary angles.
We will find that the larger angle measures 140° and the smaller one measures 40°.
------------------------
Two angles A and B are supplementary if their measures add up to 180°, so we have:
A + B = 180°.
Let's assume that B is the larger one, we also do know that:
"The larger is 20° less than 4 times the smaller"
Then we can write:
B = 4*A - 20°.
Then our system of equations is:
A + B = 180°.
B = 4*A - 20°.
To solve it we need to isolate one variable in one of the equations and replace it on the other equation. Here we can see that B is already isolated on the second equation, so we can replace it in the first one to get:
A + B = 180°.
A + (4*A - 20°) = 180°
Now we can solve this for A:
A + (4*A - 20°) = 180°
5*A - 20° = 180°
5*A = 180° + 20° = 200°
A = 200°/5 = 40°
Now that we know the value of A we can get the value of B:
B = 4*A - 20° = 4*40° - 20° = 140°
Then the larger angle measures 140° and the smaller measures 40°

Use the given table to compute the row and column totals. We simply add up values to get these totals.
Boys: 108+23 = 131 meaning that there are 131 boys total so this value will go in row 1 of the "total" column attached to the right side of the given table. See figure 1.
Girls: 99+16 = 115 will go right under 131.
Right-Handed: 108+99 = 207 will go under 99 in the "right handed" column in the "total" row.
Left-handed: 23+16 = 39 will go next to the 207 in the same total row as before
--------------------------------------------
We have the row and column totals computed. Now onto the next step.
Copy the entire table (with row and column totals) to another sheet of paper or just below the table you just wrote out. This new second table will be built upon and altered. First, erase the bottom "total" row. Now divide everything in row 1 by the total
108/131 = 0.82442748091603 which rounds to 0.82
23/131 = 0.17557251908397 which rounds to 0.18
So we'll have 0.82 and 0.18 fill in for the first row of the "Boys" row. See figure 2.
Do the same for the second row. Divide everything in this row by the total 115
99/115 = 0.8608695652174 which rounds to 0.86
16/115 = 0.1391304347826 which rounds to 0.14
The values 0.86 and 0.14 will go in the first two columns of row 2.
The totals will divide by each other to lead to 1
131/131 = 1
115/115 = 1
which explains why we have two '1's in the very right column. They represent 100%
Again, see figure 2 to see how the values are placed.
--------------------------------------------
We'll follow similar steps as before in the previous section. Copy the table from figure 1 but now erase the entire right-hand column marked "total".
Divide everything in column 1 by the total 207
108/207 = 0.52173913043479 which rounds to 0.52
99/207 = 0.47826086956521 which rounds to 0.48
207/207 = 1
Divide everything in column 2 by the total 39
23/39 = 0.58974358974359 which rounds to 0.59
16/39 = 0.41025641025641 which rounds to 0.41
39/39 = 1
See figure 3 to see how the values are filled in. The values in red are the results we got in this section. The '1's have already been filled in by your teacher.
--------------------------------------------
Side Note: In figure 2, the red values in the "Boys" row add up to 1
0.82+0.18 = 1
The same can be said for the "girls" row too
0.86+0.14 = 1
In figure 3, the red values in the "right handed column" add to 1
0.52+0.48 = 1
And similarly for the "left-handed" column
0.59+0.41 = 1
These four facts are not coincidences. For instance, 82% of the boys are right-handed so that leaves 18% left-handed boys (see row1 of figure 2). So 82% + 18% = 100% which is represented by 0.82+0.18 = 1

The length of the rectangle exceeds its breadth by 3 cm. if the length and breadth are each increased by 2 cm, then the area of new rectangle will be 70 sq. cm more than that of the given rectangle. find the length and breadth of the given rectangle.
Answers
Let's suppose the breadth of the rectangle be x cm
The length of the rectangle = x + 3 cm
It is assumed that the length and breadth of the rectangle is amplified by 2.
Now, the breadth of the rectangle = x + 2
The length of the rectangle = x + 3 + 2 = x + 5
It is also assumed that the area of the rectangle is 70 sq. cm
Hence, the area of the rectangle = length x breadth = (x + 2)(x + 5) = 70
= x2 + 5x + 2x + 10 = 70
= x2 + 7x = 70 - 10
= x2 + 7x = 60
= x2 + 7x - 60 = 0
= x2 + 12x - 5x - 60 = 0
= x( x + 12) -5(x + 12) = 0
= ( x + 12) (x - 5) = 0
=x + 12 = 10 or =x - 5 = 0
= x = 10 - 12 = -2 = x = 5
The breadth of a rectangle is never negative, so the value of x is 5 cm
Therefore, the breadth of the rectangle = 5 cm
The length of the rectangle = 5 + 3 = 8 cm

t=d+pm for p
i dont understand what this is asking me to do
Answers
pm = T - d
p = (T - d)/ m
or
p = T/m - d/m
To solve for "p" in the equation "t = d + pm," isolate "p" by subtracting "d" from both sides: "t - d = pm." Then, divide both sides by "m" to find "p": "p = (t - d) / m." This formula allows you to calculate "p" based on given values of "t," "d," and "m."
To solve for "p" in the equation "t = d + pm," you need to isolate "p" on one side of the equation. Here's how you do it step by step:
Start with the Equation:
The equation is t = d + pm, where "t" represents a value, "d" represents another value, "p" is the variable we want to solve for, and "m" is yet another value.
Isolate the "pm" Term:
To get "pm" by itself, we need to eliminate the "d" term on the right side. We can do this by subtracting "d" from both sides of the equation:
t - d = pm
Solve for "p":
Now that "pm" is isolated on the right side, we can solve for "p" by dividing both sides by "m":
p = (t - d) / m
So, the solution for "p" in terms of "t," "d," and "m" is given by the formula p = (t - d) / m. This formula tells you how to calculate the value of "p" based on the values of "t," "d," and "m."
In practical terms, this equation might be used in various scenarios. For example, if "t" represents total distance, "d" represents a fixed distance, and "m" represents a constant speed, then "p" would represent the time it takes to cover the remaining distance to reach "t." This formula can be quite useful in solving real-world problems involving time, distance, and speed.

then for first plane d = 496x
and for second plane its d = 558/(x - 0.5) , so:-

x = 4.5 hours
The first plane took 4 and a half hours
Answer:
4.5 hours
[tex]496 x= 558 x-279[/tex]
Step-by-step explanation:
We are given that two airplanes left the same airport and arrives at the same destination at the same time.
We have to find the number of hours taken by first plane to travel to the destination and find the equation that can be used to solve this problem
We are given that the first airplane left at 8:00 a.m
Let y be the distance traveled by the first airplane
The average rate of first airplane =496 miles per hour
The average rate of second airplane =558 miles per hour
Let x represents the number of hours that the first airplane traveled.
The number of hours that the second plane traveled =x-0.5
Because the second airplane take half an hour less than the first airplane
We know that [tex] distance=speed\times time [/tex]
[tex]d=496 x[/tex]
[tex]d=558(x-0.5)[/tex]
[tex]496 x= 558 x-279[/tex]
[tex]279=558 x-496 x[/tex]
[tex]279=62 x[/tex]
[tex]x=\frac{279}{62}[/tex]
x=4.5 hours
Hence, the first airplane takes 4.5 hours to travel to the destination.
If a and b are positive numbers, find the maximum value of f(x) = xa(7 â x)b on the interval 0 ⤠x ⤠7.
Answers
Final Answer:
The maximum value of f(x) = xa(7 - x)b on the interval 0 ≤ x ≤ 7 occurs when x = 7/2 for a > 0 and b > 0.
Explanation:
To find the maximum value of f(x) on the interval 0 ≤ x ≤ 7, we'll use calculus. First, take the derivative of f(x) with respect to x.
f'(x) = a * (7 - x)^b * x^(a-1) - b * a * (7 - x)^(b-1) * x^a
Setting f'(x) = 0 to find critical points:
a * (7 - x)^b * x^(a-1) - b * a * (7 - x)^(b-1) * x^a = 0
Solving for x gives x = 7/2. To determine if this point is a maximum, minimum, or inflection point, we'll use the second derivative test.
f''(x) = a * (7 - x)^(b-1) * x^(a-2) * ((a - 1) * x - 7) - b * a * (7 - x)^(b-2) * x^(a-1) * ((b - 1) * x - 7)
When x = 7/2, f''(7/2) > 0, indicating a concave-up shape and confirming it as a local minimum. Therefore, the maximum value of f(x) occurs at the endpoints of the interval, x = 0 and x = 7, or potentially at x = 7/2 if it surpasses these values.
For a > 0 and b > 0, plugging in x = 7/2 into f(x) = xa(7 - x)b yields the maximum value of the function within the given interval.
Understanding the critical points through derivatives helps identify where the maximum or minimum points occur in the function. In this case, x = 7/2 stands as the point of maximum value within the interval 0 ≤ x ≤ 7 when a and b are both positive.

Describe in words a sequence of transformations that maps ∆ABC to ∆A'B'C'.
Transformation #1
Transformation #2
Write an ordered-pair rule for each transformation in the sequence.
Transformation #1
Transformation #2
Answers
Answer: The required sequence of transformations is
Transformation 1 : a rotation by 90 degrees in the counterclockwise direction about the origin, (x, y) ⇒ (-y, x).
Transformation 2 : a translation by 2 units right and 3 units down, (x, y) ⇒ (x+2, y-3).
Step-by-step explanation: We are given to describe in words a sequence of transformations that maps ∆ABC to ∆A'B'C'.
From the figure, we note that
the co-ordinates of the vertices of triangle ABC are A(0, 4), B(0, 0) and C(2, 3).
And, the co-ordinates of the vertices of triangle A'B'C' are A'(-2, -3), B'(2, -3) and C'(-1, -1).
We see that if triangle ABC is rotated 90 degrees in anticlockwise direction about the origin, then its co-ordinates changes according to the following rule :
(x, y) ⇒ (-y, x).
That is
A(0, 4) ⇒ (-4, 0),
B(0, 0) ⇒ (0, 0),
C(2, 3) ⇒ (-3, 2).
Now, if the vertices of the rotated triangle are translated 2 units right and 3 units down, then
(x, y) ⇒ (x+2, y-3).
That is, the final co-ordinates after rotation and translation will be
(-4, 0) ⇒ (-4+2, 0-3) = (-2, -3),
(0, 0) ⇒ (0+2, 0-3) = (2, -3),
(-3, 2) ⇒ (-3+2, 2-3) = (-1, -1).
We see that the final co-ordinates are the co-ordinates of the vertices of triangle A'B'C'.
Thus, the required sequence of transformations is
Transformation 1 : a rotation by 90 degrees in the counterclockwise direction about the origin, (x, y) ⇒ (-y, x).
Transformation 2 : a translation by 2 units right and 3 units down, (x, y) ⇒ (x+2, y-3).

For the first image, the median range would be 88. In order to find the median, you'll place all your numbers in numerical order (smallest to largest). If there are an odd amount of numbers, find the one directly in the middle. If there is an even amount, you'll take the two most central ones and find the mean, that will tell you the median. Therefore, B (88) would be the answer to your first one.
The second one would be C (20.4). It's asking for the mean. In order to find the mean of a set of numbers, you'll simply add up all of the numbers and divide by how many numbers are in your number set. That gives you the mean.
