Answer:
B. 3 radians
Step-by-step explanation:
We are given the following components of the circle.
Radius of circle (r) = 4 cm
Length of arc (l) = 12 cm
Lenght of arc of a circle is given by the following formula:
[tex] l = \frac{\theta}{2\pi^c}\times 2\pi r[/tex]
Substituting the values of l and r in the above formula, we find:
[tex] 12 = \frac{\theta}{2\pi^c }\times 2\pi \times 4\\\\
\therefore 12 = \theta \times 4\\\\
\theta = \frac{12}{4}\\\\
\theta = 3 \: radians[/tex]
find the number of possible outcomes for creating an outfit from 4 pairs of pants 3 shirts and 4 pairs of shoes
Answer:
48
Step-by-step explanation:
This is a counting problem, so we can use the counting principle. Since there are 4 pairs of pants, 3 shirts, and 4 pairs of shoes, we do 4 * 3 * 4, which equals 48.
Using the Fundamental Counting Theorem, it is found that there are 48 possible outcomes for the outfit.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem, the options are as follows:
There are 4 possible pairs of paints, hence [tex]n_1 = 4[/tex].There are 3 shirts, hence [tex]n_2 = 3[/tex].There are 4 pairs of shoes, hence [tex]n_3 = 4[/tex].Hence, the total number of options given by:
[tex]N = 4 \times 3 \times 4 = 48[/tex].

SOMEONE PLEASE HELP ASAP! Normal distribution models what type of variable? A.discrete random variable B.random variable C.discrete continuous variable D.random continuous variable
A normal distribution has its center at the mean and its spread is determined by the standard deviation. For the standard normal distribution, its mean is 0 and standard deviation is 1. It is in the shape of a bell curve. Most of the values fall in or around 0, forming the peak around this area. As you move away from 0, the values are less frequent which explains the drop-off. The distribution is continuous as you can have any real number (decimal or whole). It's also random because of the nature of statistics.

Use the method of substitution to solve the system of equations. please show your work! y=534x y=74.80x+1,419 Thank you so much! If you could also solve it graphically that would be best but if not thats okay!
Answer:
( 3, 1650 ), Where x = 3, and y = 1650 -
Approximately
Step-by-step explanation:
Take a look at the procedure below;
[tex]y = 534x,\\y = 74.80x + 1,419\\\\y = 534x,\\y - 74.8x = 1,419\\\\( 534x ) - 74.8x = 1,419\\459.2x = 1,419\\x = ( About ) 3\\\\y = 534 * ( x ),\\y = 534 * ( 3.1 ),\\y = ( About ) 1650[/tex]
We first converted the second equation into standard form, by subtracting 74.8x on either side. Afterwards we substituted 534x in replacement of y in this second equation, and solved for x. Knowing the value of x, it was substituted back into the first equation to solve for the value of y. Hence, the resulting solution is ( 3, 1650 ) - approximately.

So, the combination of all those angles is 360*, since a complete circle is 360*. Now, I don't know what I have to find, but I assume its x.
So, the sum of all those angles is 360*. This means that we just need to add all them together, solve, and we have our x.
Now, see that square where in the angle? That generally means it is 90*.
Thus:

What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the triangles be represented as A and B
Now , the triangles are right angled and their congruency is given by
The hypotenuse-angle theorem, often known as the HA theorem, says that two right triangles are congruent if their hypotenuses and acute angles are parallel to one another.
Any two right triangles that have a congruent hypotenuse and a matching, congruent leg are congruent triangles, according to the HL, or hypotenuse-leg, theorem.
According to the LA, or leg-acute, theorem, a right triangle is congruent if its leg and any acute angle are congruent with the corresponding leg and acute angle of another right triangle.
Hence , the triangles are congruent

Step-by-step explanation:
From the figure attached,
ΔMON is a right triangle and coordinates of the points M and N are M(0, 2b) and N(2a, 0).
Coordinates of midpoint P → [tex](\frac{2a+0}{2}, \frac{0+2b}{2})[/tex]
From the formula of the distance between two points,
[tex]d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
[tex]\texttt {MN} = \sqrt{(2a-0)^2+(0-2b)^2}\\\\ = \sqrt{4a^2+4b^2}\\\\ = 2\sqrt{a^2+b^2}[/tex]

In the inverse variation function, what happens to the output when the
function's input value is multiplied by 4?
O A. The output is divided by 2.
OB. The output is multiplied by 4
O C. The output is negated
O D. The output is divided by 4
Answer:
Option D.
Step-by-step explanation:
An inverse variation function is defined as
[tex]y\propto \dfrac{1}{x}[/tex]
[tex]y=\dfrac{k}{x}[/tex]
where, k is constant of proportionality.
In the above equation x represents input and y represents output.
If the function's input value is multiplied by 4, then
[tex]y_1=\dfrac{k}{x_1}[/tex]
[tex]y_1=\dfrac{k}{4x}[/tex]
[tex]y_1=\dfrac{1}{4}\cdot \dfrac{k}{x}[/tex]
[tex]y_1=\dfrac{1}{4}y[/tex]
The output is divided by 4.
Therefore, the correct option is D.
