Answer:
190 games
Step-by-step explanation:
²⁰C₂ = 20!/[(20 - 2)! * 2!] = 190
The number of games that should be there is 190 games.
Calculation of the number of games:Since in Ethiopia, there are 20 premier league soccer teams.
So here we used the combination
i.e.
= ²⁰C₂
= 20!/[(20 - 2)! * 2!]
= 190
A combination refers to the mathematical technique where it measures the no of possible arrangements where the selection order should not be considered. It can be selected in any sequence.
hence, we can conclude that The number of games that should be there is 190 games.

If n(U) = 125, n(A) = 80, n(B) = 65,
then, greatest value of n(AUB) is
Answer:
650,000
Step-by-step explanation:
Given these numbers in the question, multiply all three numbers to get your final answer which is 650,000.
The greatest value of n(AUB) is "145".
An component as well as substance or entity that belongs to both A and B would be included throughout the Union. A union is denoted by "U".Given:
→ n(U) = 125
→ n(A) = 80
→ n(B) = 65
As we know,
The formula is:
⇒ [tex]n(A \cup B)_{max} = n(A)+n(B)[/tex]
By substituting the given values of n(A) and n(B), we get
[tex]=80+65[/tex]
[tex]=145[/tex]
Thus the correct answer is n(AUB) = 145.

help i can't figure this out it's algebra
Step-by-step explanation:
Part A:
The maximum point is (2.5, 2531.25). This represents that $2.5 should be decreased from the original price to achieve the most profit from t-shirt sales.
Part B:
The y-intercept is seen to be around (0, 2500). This tells us that the profit made from the original price is $2500.
Part C:
Yes. The point (25, 0) is a solution. It tells us that if we decreased the original price by $25, we would make no/zero profit.
Answer:
Step-by-step explanation:
A. The optimal decrease in price to gain the maximum profit in sale:
Meaning if you reduce the price by $2.5, you will gain the maximum profit of $2531.25
B. It represents the amount of profit without any change in the current price on the t-shirt.
By shifting and expanding the original equation [tex]y=-x^{2}\\[/tex]
[tex]y = -5(x-2.5)^{2} + 2531.25[/tex]
[tex]x = 0 => y = 2500[/tex]
C. The solution is as in part B
It represents by reducing the price of each t-shirt, there is an initial increase in profit but eventually it will drop.

Answer:
The support post positioned 23 feet far from the front of the house
Step-by-step explanation:
According to Pythagoras Theorem
(Hypotenuse)² = (Base)² + ( Perpendicular)²
We need to find Base so arranging the equation will give us
(Base)² = (Hypotenuse)² - ( Perpendicular)²
Taking under root on both sides
Base = √(Hypotenuse)² - ( Perpendicular)²
Base = √ (625 - 100)
Base = √525
Base = 23 feet

1. If the trapezoid represents 1 whole, what do each of the following shapes represent? Be prepared to show or explain your reasoning.
1. 1 triangle
2. 1 rhombus
3. 1 hexagon
only question 1
Answer:
Part(A): 1 triangle represents [tex]\dfrac{1}{3}[/tex] of whole.
Part(B): 1 rhombus represents [tex]\dfrac{2}{3}[/tex] of whole.
Part(C): 1 hexagon represents 2 whole.
Step-by-step explanation:
Consider the provided figure.
Here, it is given that the trapezoid represents 1 whole.
Part 1. Consider figure 1.
3 triangles can be group into a whole trapezoid.
[tex]3\times \frac{1}{3}=1[/tex]
Hence, 1 triangle represents [tex]\dfrac{1}{3}[/tex] of whole.
Part 2.
Consider figure 2.
Here, in figure 2 if we put 1 rhombus on the given trapezoid, we will be left with the shape is a triangle, which is [tex]\dfrac{1}{3}[/tex] of the trapezoid. Also, the triangle is [tex]\dfrac{1}{2}[/tex] of the rhombus.
We know that 3 triangles can be fit into 1 trapezoid and 2 triangles can be fit on a rhombus
Hence, 1 rhombus represents [tex]\dfrac{2}{3}[/tex] of whole.
Part 3.
Consider figure 3.
2 trapezoid = 1 hexagon
Hence, 1 hexagon represents 2 whole.

slope=4/3 y-intercept=-5
Answer: 4/3 - 5
I assume you want to know the numbers in slope intercept form so... yeah
Step-by-step explanation
Answer:
The equation of the line in point-slope form is:
[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]
The graph is also attached below.
Step-by-step explanation:
Given
Slope m = 4/3y-intercept = -5We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
As we are given the y-intercept = -5
Thus, the point (0, -5) represents the y-intercept.
Point slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case,
m = 4/3(x₁, y₁) = (0, -5)substituting m = 4/3 and the point (0, -5) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y\:-\:\left(-5\right)\:=\:\frac{4}{3}\:\left(x\:-\:0\right)[/tex]
[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]
Therefore, the equation of the line in point-slope form is:
[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]

Is 6.25 L greater than
625 ml
Answer:
Well 1 litter is already 1000 ml so already its greater
Step-by-step explanation:
6.25 litter is essentially
6250 ml
And 6250>625
Answer:
Yes
Step-by-step explanation:
First we need to know that
1 L = 1000 ml
Using that, we can see that 6.25 L = 6250 ml
(6.25 x 1000, multiply by 1000 to convert from L to ml)
Therefore, 6.25 L (or 6250 ml) is bigger than 625 ml.

A cement mixer can hold up to 681 kilograms of cement. How many 100-pound bags of cement can be put into the mixer at one time?
Answer:
15 bags
Step-by-step explanation:
Given that :
Capacity of mixer = 681 kg
Pounds per bag of cement = 100 pounds
Number of bags mixer can hold =?
Converting the capacity of mixer to pounds :
1kg = 2.205 pounds
681 kg = (681 * 2.205) pounds = 1501.605 pounds
Number of 100 pound bag of cement :
Capacity in pounds / 100 pounds
1501.605 / 100
= 15.016
= 15 bags of 100 pound cement
The waiting time for a bus has a uniform distribution between 2 and 13 minutes. What is the probability that the waiting time for this bus is less than 4.5 minutes on a given day
Answer: 0.2273
Step-by-step explanation:
Probability density function for uniform distribution is given by :-
[tex]f(x)=\dfrac{1}{b-a}[/tex], where x is uniformly distributed in [a,b].
Let x denotes the waiting time for this bus.
Given : The waiting time for a bus has a uniform distribution between 2 and 13 minutes.
Probability distribution function of x for interval [2,13] will be :-
[tex]f(x)=\dfrac1{13-2}=\dfrac{1}{11}[/tex]
Required probability : P(x<4.5) = [tex]\int^{4.5}_{2}f(x)\ dx[/tex]
[tex]=\int^{4.5}_{2}\dfrac1{11}\ dx\\\\=\dfrac1{11}[x]^{4.5}_{2}\\\\ = \dfrac1{11}(4.5-2)\\\\=\dfrac1{11}(2.5)\approx0.2273[/tex]
Hence, the probability that the waiting time for this bus is less than 4.5 minutes on a given day = 0.2273
