Using the properties of permutation and combination we can calculate that there are possible 3 ,4 ,5 ,6 or 8 people in the group.
A permutation of a set is, broadly speaking, a rearranging of its elements if the set is already ordered, or arranging its members into a sequence or linear order.
The act or procedure of altering the linear order of an ordered set is referred to as a "permutation."A combination is a choice of items from a group of different items where the order of the choices is irrelevant.There are 2 to 10 people in the group.
Lets us consider there are 3 people. Ticket price = 240 / 3= $80
Lets us consider there are 4 people. Ticket price = 240 / 4= $60
Lets us consider there are 5 people. Ticket price = 240 / 5= $48
Lets us consider there are 6 people. Ticket price = 240 / 6= $40
Lets us consider there are 8 people. Ticket price = 240 / 3= $30
Hence from the properties of permutation and combination we can see that there could be 3 ,4,5,6 or 8 people.

0.30 0.20
0.29 0.19
The unit price per ounce at Price-Club is $0.29 per ounce and the unit price per ounce at Shop Mart is $0.21 per ounce.
What is the unit price?The unit price can be determined by dividing the total cost by the total ounce that is purchased.
Division is the process of putting a number into equal groups using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. The result of the division process is known as the quotient. Other mathematical operations include addition, subtraction and multiplication.
Unit price = total cost / total ounce sold
Unit price of Price-Club = $3.44 / 12 = $0.29 per ounce
In order to determine the unit price of Shop Mart, pounds have to be converted to ounces
1 pound = 16 ounces
To convert 2 1/2 pounds to ounces, multiply 2 1/2 by 16. Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

Arnold plants a tree sapling in his yard and measures its height every year. His measurements so far are shown in the scatterplot.
The equation of the scatter plot is y = 5/3x + 2 and the tree will be 18.7 feet in ten years
What are linear equations?Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the height of the tree?The information that completes the question is added as an attachment
From the scatter plot, we have the following points
(x, y) = (0, 2) and (6, 12)
The equation of the line is calculated as
y = (y2 - y1)/(x2 - x1) * (x - x1) + y1
Substitute the known values in the above equation
So, we have
y = (12 - 2)/(6 - 0) * (x - 0) + 2
So, we have
y = 5/3x + 2
In ten years, the value of x is
x = 10
So, we have
y = 5/3 x 10 + 2
Evaluate
y = 18.7
Hence, the height of the tree is 18.7 feet

A house has decreased in value by 35% since it was purchased. If the current value is $78,000, what was the value when it was purchased?
Answer: The value of the house when it was purchased was 120,000
Step-by-step explanation:
1) Set up the equation. Let x be the house.
x-x*35%= 78,000
First, the house decreases 35% of the cost of the original house. It now costs 78,000.
2) Solve the equation.
x-x*0.35 = 78,000
x-0.35x=78,000
0.65x = 78,000

Find the values of a,b and c that would make the statements true.
1) (ax+2)(5x+b)=10x^2+bx+c
The values of a, b and c are a = 2, b = -10 and c = -20
How to determine the values of the variables?The equation is given as
(ax + 2)(5x + b) = 10x^2 + bx + c
Open the brackets
So, we have
5ax^2 + 10x + abx + 2b = 10x^2 + bx + c
By comparing the above equation.
We have the following set of equations
5a = 10
10 + ab = b
2b = c
By solving the equations, we have
a = 2
Substitute a = 2 in 10 + ab = b
10 + 2b = b
So, we have
b = -10
Substitute b = -10 in 2b = c
2(-10) = c
Evaluate
c = -20
Hence, the values of the variables are a = 2, b = -10 and c = -20

If triangle LMN has an obtuse angle at vertex M, which statements could be true? Check all that apply.
Triangle LMN is an obtuse angle then, the angle at vertex L is acute, the angle at vertex N is acute.
The triangle LMN is an obtuse angle at the vertex M. So by the definition of obtuse angle triangle LMN is an obtuse angle.
As ∠M is an obtuse angle
So 90° < m∠M < 180°
By the property of a triangle,
m∠L + m∠M + m∠N = 180°
m∠M = 180° - (m∠L + m∠N)
90° < 180° - (m∠L + m∠N) < 180°
90° - 180° < -(m∠L + m∠N) < 0
-90° < -(m∠L + m∠N) < 0
90° >(m∠L + m∠N) > 0
90° > m∠L and 90° > m∠N
Therefore both angles L and N are acute angles.

Use the intersect method to solve the equation. x^2 - 3x = x^2 -1
The coordinate that represent the solution of the equation -
x² - 3x = x² - 1 is (0.333, -0.8889).
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given is the following equation -
x² - 3x = x² - 1
In order to solve it using intersect method, we will plot the graphs of both functions and find the point of intersection of graphs of both the equations.
Assume -
f(x) = x² - 3x
g(x) = x² - 1
Now, the point of intersection of both the graphs will be the solution to the equation given by -
f(x) = g(x)
It can be seen from the graph that, both the graphs intersect at the coordinate (0.333, -0.8889). This coordinate will be the solution set of the equation -
f(x) = g(x)
Therefore, the coordinate that represent the solution of the equation -

A store has two types of animal feed available. Type A contains 3 pounds of oats and 3 pounds of corn per bag. Type B contains 1 pound of oats and 7 pounds of
corn per bag. A farmer wants to combine the two types so that the resulting mixture has at least 18 pounds of oats and at least 54 pounds of corn. The store
only has 11 bags of type A feed and 12 bags of type B feed in stock. Type A costs $4 per bag, and type B costs $1 per bag. How many bags of each type should
the farmer buy to minimize her cost?
Note that the ALEKS graphing calculator can be used to make computations easier.
Type A feed:
Type B feed:
bag(s)
bag(s)
The farmer will purchase five bags of kind A and six bags of type B.
Per bag, Type A includes 9 pounds of oats and 3 pounds of maize.
Per bag, Type B includes 2 pounds of oats and 10 pounds of maize.
The farmer is looking for a blend that comprises at least 57 pounds of oats and 75 pounds of maize.
Allow the farmer to mix type A feed = x pounds.
and feed type B = y pounds
(9x + 2y) pounds of oats when blended
Corn amount when combined: (3x + 10y) pounds
Oats equation: 9x + 2y = 57 ———— (1)
Corn equation: 3x + 10y = 75 ————- (2)
Subtract equation (2) from equation (2) by multiplying it by three (1)
3(3x + 10y) - (9x + 2y) = 75×3 - 57
9x + 30y - 9x - 2y = 225 - 57
28y = 168
y = 6 bags
derived from the equation (1)
9x + 2×6 = 57
9x + 12 = 57
9x = 57 - 12
9x = 45
x = 5 bags
Because the business has 15 bags of each sort, each bag costs $4.
As a result, the cost of 5 bags of type A and 6 bags of type B is = (54) + (64)
= 20 + 24
= $44
The farmer intends to buy five bags of kind A and six bags of type B.

How do I solve number 4 and 5 to get the correct answer?
Answer:
4. (d)
5. (b)
Step-by-step explanation:
You want to apply the secant and chord rules to the circles given in the diagram.
The secant rule is "the product of distances from the point of intersection of secants to the two points of intersection of the secant with the circle is the same for both secants." A tangent can be considered to be a secant that has both points of intersection with the circle in the same place.
The chord rule is similar to the secant rule: "The product of distances from the point of intersection of the chords to their intersection with the circle is the same for both chords."
4.The diagram shows a tangent of length 12, so the product of distances to the two points of intersection with the circle is 12(12).
The secant has length 8 to the near point of intersection, and (x+8) to the far point of intersection. That product is the same as for the tangent:
8(x +8) = 12(12) . . . . . . matches choice D
5.One chord has lengths of 14 and x, so the product of those is 14x.
The other chord has lengths of 12 and 21, so the product of those is 12(21).
The product is the same for both chords, meaning ...
14x = 12(21) . . . . . . matches choice B

Additional comment
We have purposely tried to write the rules in "parallel" fashion, because we find them easier to remember that way. Considering a tangent to be a secant with the points of intersection with the circle merged means the same rule can be used for all three cases:
