The greatest number of days that can be arranged in which no pair of the four students work together more than once is 6.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Two students are needed to work in the school store during the lunch hour every day, and four students volunteer for this work.
Now, By the formula of combination we get;
The greatest number of days that can be arranged in which no pair of the four students work together more than once is,
⇒ [tex]^{4} C_{2}[/tex]
⇒ 4! / (4 - 2)! 2!
⇒ 4! / 2! 2!
⇒ 4×3/2
⇒ 6

PLEEZE WILL GIVE BRAINLIEST!!!
Answer:
91390
I hope you will give brainliest
Step-by-step explanation:
So a dealer has 40 cars and he wants to put them on display for at a time when order doesn't matter. So that means we have a combination problem. And the number of combinations with N. Being the number in the sat in this case that's 40 are being the number that you choose being four. It's going to give me formulas and factorial over R. Factorial times N minus R. Factorial. So we want combinations of four things 40 things taken four at a time. So that's going to give me 40 factorial Over four factorial times 40 for factorial. That gives me 40 factorial Over four factorial times 36 factorial. So on top I'm going to have 40 Times 39 times 38 Times 37 over four times 3 times two Times one. Because the 38 factorial Will cancel out from 36 down or the 36 factorial rather. So let's see what that gives me 40 times 39 times 38 times 37. That is gonna give me (219) 336 0 divided by 24. That is gonna give me a total of 913 90 91,390 ways that you can display them. So this is choice C. C. For combination

The area of 5 circles and 10 semicircles and 100 quarter circles stones which has the 10 inches radius is 10995.6 in².
What is the area of the circle?The area of the circle is the space occupied by it. It can be given as,
A=πr²
Here, (r) is the radius of the circle.
The radius of one stone is 10 inches. Thus, the area of one circular stone is,
A=πr²
A=π(10)²
A=314.16 in².
There are total 5 circles and 10 semicircles and 100 quarter circles. The area of 5 circle is,
A=5 x 314.16 in²
A=1570.8 in².
The area of circle is twice the area of semicircle and 4 times the area of quarter circle. Thus the area of 10 semicircle and 100 quarter circles is,
A(semicircle)=(10 x 314.16 in² )/2=1570.8 in².
A(quarter circle)= (100x 314.16 in² )/4=7854 in².
The total area is,
A=1570.8 +1570.8 +7854
A=10995.6 in².
Thus, the area of 5 circles and 10 semicircles and 100 quarter circles stones which has the 10 inches radius is 10995.6 in².

The table shows the amount of produce sold at a farmer's market in the morning.
Type of Produce Number Sold
apples 40
sweet corn 80
pears 30
The farmer expects to sell 240 pieces of produce in the afternoon. Based on this morning's results, how many apples can be expected to be sold?
apples
Answer:
64 apples
Step-by-step explanation:
We assume that the proportion of apples sold in the afternoon is the same as it is in the morning.
__
setupThe number of pieces of produce sold in the morning was 40+80+30 = 150. Of these, 40 were apples. At that same rate, the sale of apples in the afternoon is expected to be ...
apples/total = apples/240 = 40/150
solutionMultiplying by 240, we find the expected sale of apples to be ...
apples = 240(40/150) = 64
64 apples can be expected to be sold in the afternoon.

Mathew is a financial analyst for a surf board company. He has found an equation for the revenue of selling t-shirts with the company logo to be r= -3p^2 + 60p +1060, where p is the price of the company’s product. What should he use to determine the price of maximum sales?
Answer: The price of maximum sales is $160
Step-by-step explanation:
This question requires you to find the vertex of this equation. The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
since the coefficient of the [tex]x^2[/tex] term is negative, the vertex will be the highest point on the graph.
this quadratic equation is in standard form: [tex]y = ax^2+bx+c[/tex].
From this, we can derive:
[tex]a = -3[/tex]
[tex]b = 60[/tex]
[tex]c = 1060[/tex]
First, determine the axis of symmetry ([tex]p[/tex] is the variable for the horizontal axis ([tex]x[/tex]) in this instance). This will be our x-coordinate of the vertex.
[tex]p = \frac{-b}{2a}[/tex]
[tex]p = \frac{-(60)}{2(-3)}[/tex]
[tex]p = \frac{-60}{-6}[/tex]
[tex]p=10[/tex]
Then, substitute the axis of symmetry into the function to find the y coordinate of the axis of symmetry. r stands for the variable for the vertical axis in this instance. This will be our y-coordinate of the vertex.
[tex]r = -3(10)^2+60(10)+1060[/tex]
[tex]r = 160[/tex]
As we have determined both the x and y coordinate of the vertex for this equation, we can determine that the maximum point is at [tex](10, 160)[/tex].
the maximum price ([tex]r[/tex]) is 160
n/8=11/5 what does n equal
Answer:

Step-by-step explanation:
▶︎◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◀︎
[tex]Hello[/tex] [tex]There![/tex]
We are asked to find the value of n in the equation [tex]\bold{\displaystyle\frac{n}{8} =\frac{11}{5}}[/tex].
It's not hard, I promise! I am going to take you through a few steps, and we'll find the answer.
Are you ready? Then let's begin... :)
[tex]Procedure:[/tex]
First, we need to multiply both sides by the denominator of n/8, which is 8:
[tex]n/8*8=(11/5)*8[/tex]
On the left side of the equal sign, the 8's cancel, leaving us with n.
[tex]n=(11/5)*8[/tex]
We can write 8 as 8/1. Now we multiply 11 times 8 and 5 times 1:
[tex]n=(11*8/5*1)[/tex]
Which is the same as
[tex]n=88/5[/tex]
▲ this answer is already in it's simplest form, we can't simplify it further

Answer:
432 ft^2
Step-by-step explanation:
The formula for the area of a circle is A=pi*r^2. In this case, because 3 is pi, it's A=3*r^2. We have the diameter of the circle, but we need the radius. The radius is 1/2 the diameter, so it's 12. 12^2=144, and 144*3 is 432, so that's our answer.
Hope this helps!
Answer:
432 ft to the power of 2
Step-by-step explanation:

Based on visual inspection of the dot plots, which of the following groups appears to have the longer average forearm length?
A. Group A, because no child in the group has a forearm length longer than 11 inches
B. Group B, because two children have a forearm length longer than 11 inches
C. Group A, because three children in the group have the least forearm length of 9 inches
D. Group B, because a child in the group has the least forearm length of 9 inches
Answer:
The correct option is B.
Step-by-step explanation:
From the given dot plot we can say that 3 children have 9 in. long forearm, 4 children have 10 in. long forearm and 3 children have 11 in. long forearm.
The average of length of forearms of Group A is
The average of length of forearms of Group A is 10 inches.
From the given dot plot we can say that 3 children have 10 in. long forearm, 5 children have 11 in. long forearm and 2 children have 12 in. long forearm.
The average of length of forearms of Group B is
The average of length of forearms of Group B is 10.9 inches.
10.9>10 it means Group B has longer average forearm length. It is true because two children have a forearm length longer than 11 inches.
Therefore the correct option is B.

you multiplied first 1 times 8 and then divide by 2 in which you will get an answer of 4/8 and to check it you divide 1/2 which gives you 0.5 and then divide 4/8 to see if it is an equivalent fraction and it will give you 0.5 in which yes sir its an equivalent fraction so 4/8 is the correct answer and have a great day.
