Answer: 53,130 possible combinations
Step-by-step explanation:
First, we want to find how much is the 20% of 25.
This is:
N = (20%/100%)*25 = 5.
So 5 students out of 25 are selected.
When we want to calculate the number of combinations of N elements it a group of K elements, we have:
[tex]C = \frac{N!}{(N - K)!*K!}[/tex]
Here N = 25, and K = 5
[tex]C = \frac{25!}{20!*5!} = \frac{25*24*23*22*21}{5*4*3*2*1} = 53,130[/tex]
so we have 53,130 combinations.

Enter abs(x) for |x|
Answer:
y=|x+2|+1
Step-by-step explanation:
the equation for absolute value is y=a|b(x-h)|+k, however, in this case the equation is just y=|x-h|+k
the x value is shifted left 2 so it's |x+2|
the y value is shifted 1 up so it's +1
the equation for the graph is y=|x+2|+1
Answer:
y =|x+2|+1

In your piggy bank, you have 15 quarters, 2 dimes, 1 nickel and 32 pennies. You tip the bank, and out rolls one, then another , then another coin. Find the probability that the coins came out as the follows:
a) 1 penny, 1 quarter, 1 dime
b) 1 penny, 1 quarter, 1 penny
Please show work. Thank You!
Answer:
B) Is the answer.
Step-by-step explanation:
If you have 15 quarters and 32 pennies, you have more than twice the amount of pennies that you do quarters. There is a small chance that it could be a dime or a nickel but this is unlikely. The chance of a quarter and penny falling out is much greater than a dime or nickle.
which polynomial has a leading coeficient of 4 and a degree of 3
Answer:
The answer is "[tex]\bold{4x^3+x^2+2}[/tex]".
Step-by-step explanation:
Some information which is choices is missing in the given question, so the correct choice can be described as:
The degree of the polynomial relates to its maximum "x" power, which occurs in the equation. Its leading coefficient shows the number until the "x" max power, that's why the equation "[tex]4x^3+x^2+2[/tex] " is the correct answer to this question.The graph of the function f (x) = StartFraction 6 Over x minus 3 EndFraction is shown below. On a coordinate plane, a hyperbola is shown. Both curves approach x = 3. What is the vertical asymptote of the function? x = –3 x = –2 x = 0 x = 3
Answer:
D.) x=3
Step-by-step explanation:
its right
The function will form a vertical asymptote at [tex]x=3[/tex].
Option D: [tex]x=3[/tex] is correct.
Given:
The function is [tex]f (x) = \dfrac{ 6} { x - 3 }[/tex].
We need to find the vertical asymptote of the function.
The given function is a rational function in which the denominator is [tex]x-3[/tex].
Now, the denominator should not be equal to zero.
As the function approaches [tex]x=3[/tex], the function will lead to infinity (positive or negative).
So, the function will form a vertical asymptote at [tex]x=3[/tex].
Option D: [tex]x=3[/tex] is correct.

3x + 4 = 13 solve for X
Answer:
x = 3
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
First, subtract 4 from both sides:
3x + 4 (-4) = 13 (-4)
3x = 13 - 4
3x = 9
Next, divide 3 from both sides:
(3x)/3 = (9)/3
x = 9/3
x = 3
3 is your answer for x.

area of the shaded segment of a circle. radius is 10 arc measures 90 degrees
Answer:
[tex]25\pi[/tex] or about 78.54 units
Step-by-step explanation:
Since the arc measures 90 degrees, since 90/360=1/4 the segment is 1/4 of the area of the circle. The whole area of the circle is [tex]\pi 10^2=100\pi[/tex], meaning that the area of the segment is [tex]25\pi[/tex] square units, or about 78.54. Hope this helps!

A bowl of fruit is on the table. It contains 3 apples, 2 oranges, and 5 bananas. Ethan and Jordan arrive home from school and randomly grab one fruit each. What is the probability that both grab an apple?
show work pls thanks!
Answer:
1/15
Step-by-step explanation:
There are a total of 10 fruits, 3 of which are apples.
The probability that the first selection is an apple is 3/10.
There are now 9 fruits remaining, 2 of which are apples. So the probability that the second fruit is an apple is 2/9.
The total probability is (3/10) (2/9) = 1/15.
Find the area of each sector. Photo attached
Answer:
Area of sector: 48π in^2; Option D
Step-by-step explanation:
~ We can see that the bolded portion of the circle must be the the sector that we need to compute the area of... ~
Let us plan out this problem. If we were to find the area of the circle provided a radius of 12 inches, we could create a proportionality between the degree of the sector, and the degree of the circle ( 360 ) and the area of the sector and the area of the circle.
1. To calculate the area of this circle, let us apply the formula πr^2, such that r is 12 inches ( and let us keep π in terms of π ) ⇒ π * ( 12 )^2 ⇒ 144 * π ⇒ Area of Circle: 144π
2. Let us see this as a proportionality:
Degree of sector/ Degree of circle = Area of sector/ Area of circle
3. Now let us say x ⇒ Area of the sector. Substitute values into this formula, and solve for x through algebra:
120 / 360 = x / 144π,
120 * 144π = 360 * x,
17,280π = 360 * x,
x = 17,280π / 360,
Area of sector: 48π in^2

how many 1/3 fraction unit cubes does it take to fill the prism?
Answer:
36 cubes
Step-by-step explanation:
Im pretty sure that you have to divide 4 by 1/3*1/3, so 4÷1/9 which is 36 do keep change flip to get 4/1 * 9/1 and multiply 4 by 9 to get 36/1 which is 36. I hope this helps

The communitive property is when changing the order of the operands does not change the result. For this equation if you had it as 7 * 5 it would equal 35 and when it is 5 * 7 it would still equal 35.
A triangular prism. The triangular base has a base of 11 inches and height of 7 inches. The height is 9 inches. The formula for volume of a prism is V = Bh. The variable B stands for the . In this prism, B equals in.2. The variable h stands for . In this prism, h is in. The volume of the prism is in.3. This question is from e2020
Answer:
Variable B is the area of triangular base.
B = 38.5 [tex]in^{2}[/tex].
Variable h is the height of pyramid.
In the given prism, h is 9 inches.
The volume of prism is 346.5 [tex]in^{3}[/tex].
Step-by-step explanation:
Please refer to the attached image for the detailed labeling of all the sides.
[tex]\triangle ABC[/tex] is the triangular base of the prism.
BC is the base of triangular base of the prism.
AP is the height of triangular base.
Area of triangular base is represented by B and is calculated by following formula of area of a triangle.
[tex]Area = \dfrac{1}{2} \times \text{Base}\times \text{Height}[/tex]
[tex]\Rightarrow \dfrac{1}{2} \times 11 \times 7\\\Rightarrow 38.5\ in^{2}[/tex]
Hence, B = 38.5 [tex]in^{2}[/tex].
Height of prism, h = 9 in
h is represented as side BE in the attached image.
It is know that volume of prism is given as :
V = Bh
Putting values of B and h:
[tex]V = 38.5 \times 9\\\Rightarrow V = 346.5\ in^{3}[/tex]
Answer:
The formula for volume of a prism is V = Bh.
The variable B stands for the ✔ area of the base.
In this prism, B equals ✔ 38.5 in.².
The variable h stands for ✔ height.
In this prism, h is ✔ 9 in.
The volume of the prism is ✔ 346.5 in.³.

The equation of a circle is given below.

((left parenthesis ,,comma ))right parenthesis What is its radius? If necessary, round your answer to two decimal places. units
Answer:
The radius is 4 units long.Step-by-step explanation:
The given equation is
[tex](x-0.5)^{2} +(y-3.5)^{2} =16[/tex]
This equation belongs to a circle, which center is at (0.5, 3.5) and its radius is 4.
You can deduct its elements, becase this equation of the circle is explicit, which means the constant term represents the square power of the radius. Solving that, we have
[tex]r^{2} = 16\\r=\sqrt{16}\\ r=4[/tex]
Therefore, the radius is 4 units long.
