If there are eleven people on the team and nine positions, how many total arrangements of the players can be made? if amy does not want to play pitcher, then there are now people available to pitch. assuming the pitcher has already been chosen, there are ten remaining players and remaining positions. how many ways are there to arrange the remaining players and positions?
There are 19958400 ways if 9 people are selected for positions and if Amy does not want to play then the number of ways will be 1814400 if done through permutations.
Given there are 11 people and nine positions.
We have to find the number of ways in which arrangement can be done if there are 11 people and 9 positions and the number of ways to arrange if Amy doe not want to play assuming the pitcher has already been chosen.
Permutations helps us to know the number of ways an object can be arranged. It is denoted by n[tex]P_{r}[/tex]=n!/(n-r)!
where n is the number of choices available,
r is the choices.
Given that the team has 11 players while there are only 9 positions available, the number of ways is 11[tex]P_{9}[/tex]=11!/(11-9)!
=11!/2!
=19958400
Now Amy does not want to play, therefore the number of ways the remaining people can be arranged in the place of pitcher is 10. Also the positions has also decreased from 9 to 8.
Thus the number of ways in which remaining people can be arranged are: 10[tex]P_{8}[/tex]=10!/(10-8)!
=10!/2!
=1814400
Hence the number of ways in which 11 people are arranged is 19958400 and the number of ways in which the remaining players are arranged is 1814400.

What is the quotient of this equation
Answer:
30
Step-by-step explanation:
First Convert Mixed Number to Improper
[tex]6\frac{2}{3} = \frac{2+3*6}{3} = \frac{2+18}{3} = \frac{20}{3}\\\\\frac{20}{3} \div \frac{2}{9}\\[/tex]
Next, we know that when dividing fractions, there is a certain pattern to follow.
It goes like this:
[tex]\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} = \frac{ad}{bc}\\\\[/tex]

WORK FOR SOLUTION
[tex]\frac{20}{3}\times\frac{9}{2} \\\\\frac{180}{6}\\\\\ =30[/tex]
Answer:
Hello! the answer to this question is 30.
Step-by-step explanation:
To solve for the quotient, we have to convert the mixed number to an improper fraction:
[tex]6\frac{2}{3} = \frac{6*3 + 2}{3} = \frac{20}{3}[/tex]
When dividing fractions, we have to flip the divisor to its reciprocal. When doing so, the divisor [tex]\frac{2}{9}[/tex] becomes [tex]\frac{9}{2}[/tex].
Now that we have the reciprocal, the operation will change from division to multiplication. We can take the final steps to solve the problem:
[tex]\frac{20}{3} * \frac{9}{2}[/tex]
This leaves you with a result [tex]\frac{180}{6}[/tex]. This can further be simplified by doing 180 ÷ 6 to get 30.
Therefore, the quotient is 30.
Casper has some whipping cream that is 18% butterfat and some milk that is 4% butterfat. He wants to make 500 ML of them that is 12%, percent butterfat.
Here's a graph that shows a system of equations for this scenario where x is the volume of whipping cream he uses and y is the volume of milk he uses.
See Correct Answer attached!
The solution to the system of equations from the graph is x = 285.7 and y = 214.3
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the the volume of milk he uses and x the volume of whipping cream he uses. Hence:
x + y = 500 (1)
Also:

Marvin will receive a scholarship each semester for $958.35 money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items is mathematically given as
$4512.6
How much money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items?Savings with Marvin = $2,595.9
Scholarship amount = $958.35
Total Scholarship amount received in 2 semesters = $958.35 X 2 = $ 1916.7
Now total money that Paolo have = (Savings with Marvin) + (Total Scholarship amount received in both semesters) = $2,595.9 + $1916.7 = $ 4512.6
Tuition & books cost = $2000
Tuition & books cost for 2 semesters = $2000 X 2 = $4000
Housing cost for 2 semester contract =$1,000
Total expenses in books and housing = $4000+ $1000 = $5000
Money left with Marvin after Total expenses in books and housing = $ 4512.6 - $5000 = −487.4
This means he has overspent.

Which of the following functions are continuous?
Answer:
B. I, II, and III
Step-by-step explanation:
A function is continuous if it is defined everywhere and its graph can be drawn without lifting the pencil. That is, at every point, the limit from the left and the limit from the right must equal each other and the function definition at the point.
Looking at choicesAll polynomial functions with real coefficients are continuous everywhere. (Choices I and II.) They have no discontinuities.
Rational functions will have a discontinuity wherever the denominator is zero. Here, the one rational function has a denominator of x^2+1, which is always positive (never zero). The given rational function is continuous everywhere (Choice III.)
All of the functions in the problem statement are continuous: I, II, and III.

D. 8.55
Answer:

Step-by-step explanation:
to find the average of multiple numbers, we add them together and divide by the number of values we combined
for example: the average of 1, 2, and 3:
1 + 2 + 3 = 6
6 / 3 (because there were 3 numbers) = 2
so, this average would be 2.
Let's add the weights (I have changed these into a denominator of 20, so that they can be easily added. Let me know if you need clarification on how I did so)
1 1/2 pounds, 4 3/4 pounds, 2 3/10pounds
1 1/2 = 1 10/20
4 3/4 = 4 15/20
2 3/10 = 2 6/20
1 10/20 + 4 15/20 + 2 6/20 = 7 31/20
7 31/20 = 8 11/20
8 11/20 = 8.55
8.55 / 3 = 2.85
so, the average weight of these packages is 2.85 [pounds]

Two equations are given below:
m + 5n = 20
m = n − 4
What is the solution to the set of equations in the form (m, n)?
(3, 7)
(0, 4)
(5, 1)
(2, 6)
Answer:
(0,4)
Step-by-step explanation:
Because the problem gives you the value of what m would equal in terms of n you would substitute n - 4 for m in the equation above, resulting in:
n - 4 + 5n = 20
6n - 4 = 20
6n = 24
n = 4
Now that you know n = 4, you already can see that the answer would be (0,4), however to check you can substitute 4 for n into the second equation.
m = 4 - 4
m = 0
Because this results in m = 0, that tells you that (0,4) is the right answer.
Answer:
(0, 4)
Step-by-step explanation:
So you can solve the equation by substitution. The solution of a systems of equations, is when they both intersect, or when the (x, y) values are exactly equal, which is why I can substitute the m of the second equation into the first equation, because I'm looking for when they're equal, and that is when m is going to be equal in both equations, as well as the n value.
original equation:
m + 5n = 20
substitute n-4 as m in the equation
(n-4) + 5n = 20
simplify:
6n-4 = 20
add 4 to both equations
6n = 24
divide both sides by 6
n = 4
Now to find m, simply substitute 4 as n in either equation:
Original equation:
m = n - 4
substitute 4 as n
m = 4-4
m=0
so m=0, and n=4, so the solution in the form (m, n) = (0, 4)
