After solving the linear programming problem, we get the answer as 250.

What is linear programming?

When a linear function is exposed to multiple restrictions, linear programming maximizes or minimizes the function. This method determines the best way to use the resources that are currently available and aids managers in using the process to make decisions about the most efficient use of scarce resources, such as money, time, materials, and machinery. Linear programming has been useful for guiding quantitative decisions in business planning, industrial engineering, and—to a lesser extent—in the social and physical sciences.

Solution explained:

[tex]\left \{ {{2x + y = 12} \atop {x + y = 7}} \right.[/tex]            x=3, y=4    P(3,4)       Coordinates of the solution point

[tex]\left \{ {{x + y = 7} \atop {x + 2y = 10}} \right.[/tex]            x=4, y=3    Q(4,3)      

                                                           Coordinates of the simultaneous eqs.

[tex]\left \{ {{2x + y = 12} \atop {x + 2y = 10}} \right.[/tex]            x=14/3, y=8/3

Putting the values of x and y in the equation P = 30x + 40y and calculating we get

P(P) = 250, P(Q) = 240, P(R) = 246.67

So, the answer is 250

Booker's father amount of commission earned is 668.31 dollars.

Sophia needs to make sells of 16744 dollars in order to earn at least 1800 dollars in commission.

Booker's father sells computer software and earns a 4.25% commission on every software package he sells.

The amount of commission he will earn after selling a software package of $15, 725 can be calculated as follows:

amount of commission earned = 4.25% of 15725

amount of commission earned =  4.25 / 100 × 15725

amount of commission earned = 66831.25 / 100

Therefore,

amount of commission earned = 668.3125

amount of commission earned = 668.31 dollars

Sophia needs to earn at least 1800 dollars each month to cover her living expenses.

The minimum she needs to sell in order to earn at least 1800 dollars if she earns 10.75% commission can be calculated as follows:

let

x = amount she needs to sell

Therefore,

10.75% of x ≥ 1800

10.75 / 100 x ≥  1800

multiply both sides by 100

10.75x ≥ 180000

divide both sides by 10.75

x ≥ 16744.1860465

x ≥ 16744

Therefore, she needs to sell 16744 dollars worth of goods.

1. It will take 5 hours for the five-gallon tank full of water to become empty at the drainage rate of 1/(1 + t) gallons per hour.

2. A correct setup of the equation problem above in terms of function is D. None of these will give the correct solution.

An equation is a mathematical statement that shows that two or more mathematical expressions share equality or are equivalent.

Functions, which are mathematical expressions involving one or more variables known as domain (or the independent variable) and range (or the dependent variable), using the equation symbol to show that two expressions are equal.

Drainage rate per hour = 1/(1 + t) gallons

t = 0

The capacity of the tank = 5 gallons

1/(1 + t) gallons

= 1/(1 + 0) gallons

= 1/1 gallons

= 1 gallon per hour

Since the tank is 5 gallons, it will take = 5 hours (5/1)

Thus, based on the drainage equation rate, the five-gallon tank will empty in 5 hours.

The total number of people in the 18-21 age bracket is 93. The number of people in this bracket who responded is 79. The number of people in this bracket who refuse to respond is 14. The total number of people in the 22-29 age bracket is 251. The number of people in this bracket who responded is 219. The number of people in this bracket who refuse to respond is 32.

A person is randomly selected from all the people surveyed. We need to find out the probability of getting someone in the 18-21 age bracket or someone who responds. Let the variables E1 and E2 represent the events.

E1 is the event of getting a person from the 18-21 age bracket.

E2 is the event of getting a person who responds.

P(E1∪E2) = P(E1) + P(E2) - P(E1∩E2)

P(E1∪E2) = (93/344) + [(79 + 219)/344] - (79/93)

P(E1∪E2) = 0.27035 + 0.86628 - 0.84946

P(E1∪E2) = 0.28717

Hence, the probability of getting someone in the 18-21 age bracket or someone who responds is 28.7%.

The lengths of the base of the triangle are 31cm while the height of the triangle is 39cm

A triangle is a polygon that has 3 sides, three angles and three vertices whose sum of angles equal to 180 degrees.

How to find the lengths and height of a triangle?

from the statement,

A=1/2bh

A=1/2 xbx(8+b)

cross multiplying,

713 = 8b+b²

rearrange the function

b²+8b-713=0

Simplyfying the equation,

(b²+23b)-(31b-713)=0

b(b+23)-31(b+23)=0

b-31=0 or b+23 =0

b=31 or b=-23

length cannot be negative. therefore base = 31cm

Line plot , because a small number of scores are reported individually

What is a line plot?

A line plot is a graph that shows data as points or check marks above a number line, indicating the frequency of each value.

If we need to compare two different groups , a line chart does have one advantage for visualizing frequency distributions

Given data ,

Total number of athletes = 15

The score points of athletes = { 1 , 2 , 3 , 4 , 5 }

The number of athletes = { 1 , 2 , 3 , 4 , 5 }

The best option to plot the line plot because of the data set

The line plot , a data visualization chart that more accurately represents the small data set, is chosen.

And , to begin, unlike a line plot , a histogram involves data ranges or intervals. A line plot uses a dot to represent each observation, whereas a histogram divides the data into intervals, masking the identity of each observation

Furthermore, because line plots are one of the simplest statistical plots, they are better suited to small to moderate-sized data sets. They are more effective than histograms at highlighting clusters and gaps

Answer:D

Step-by-step explanation:

By using the distributive property, we will rewrite the expression as:

2n*(5m -1) = 10*n*m - 2n

The distributive property of the multiplication says that the product:

A*(B + C)

Can be rewritten as:

A*(B + C) = A*B + A*C

So we are "distributing" the product.

In this case, we have the expression:

2n*(5m - 1)

If we apply the distributive property, then we will get:

2n*(5m - 1) = (2n)*(5m) + (2n)*(-1)

Now we can simplify this expression to get:

(2n)*(5m) + (2n)*(-1) = 10*n*m - 2n

That is what we wanted to get.

The number of groups, using the combination formula, for each case, is given as follows:

a) Same number of students from each grade: 1,245,816,000

b) At least two grade nine students: 31,650,886,995.

c) James and Lucy are in it: 2,481,256,778.

The number of groups is obtained for the three cases using the combination formula, as the order in which the students are chosen is not important.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, obtained by the following formula, involving factorials.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

For item a, the same number of students is taken from each class, hence 3 students are taken from each class, as 12 students are taken from 4 classes, hence 12/4 = 3.

Hence the number of groups, considering the number of students in each class, is of:

[tex]C_{10,3}C_{11,3}C_{12,3}C_{13,3} = \frac{10!}{7!3!} \times \frac{11!}{8!3!} \times \frac{12!}{9!3!} \times \frac{13!}{10!3!} = 120 \times 165 \times 220 \times 286 = 1,245,816,000[/tex]

For item b, we use complementary events, first obtaining the total number of students that can be taken, and then removing the combinations that do not have at least two grade nine students.

The total number of groups is obtained as follows:

[tex]C_{46,12} = \frac{46!}{12!34!} = 38,910,617,655[/tex]

(as there are 10 + 11 + 12 + 13 = 46 students, and 12 are taken).

The number of groups with none students from grade 9 is:

[tex]C_{36,12} = \frac{36!}{12!24!} = 1,251,677,700[/tex]

(removing the 10 students from grade 9).

The number of groups with one student from grade 9 is:

[tex]C_{10,1}C_{36,11} = 10 \times \frac{36!}{11!25!} = 6,008,052,960[/tex]

(one from grade 10 and the remaining from the other classes).

This the number of groups with at least two grade 9 students is calculated as follows:

38,910,617,655 - (1,251,677,700 + 6,008,052,960) = 31,650,886,995.

For item c, considering Jamie and Lucy in it, the remaining 10 students are taken from a set containing the 44 remaining students, hence:

60 degrees is he angles which are made by bracket with the wall

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The shelf is perpendicular to the wall.

The shelf makes an angle of 90 degree to the wall because when the shelf is perpendicular then the wall and shelf should be ninety degrees.

From the shelf edge to wall there creates an angle x.

We need to find the angle x.

As it forms a right angle triangle one angle is 90 degrees and the other angles should be 60 degrees and 60 degrees.

Hence 60 degrees is the angles which are made by bracket with the wall

The number of months after which she will be able to vault 11 feet is 30 months.

For a pole-vaulter in training, the height the athlete will be able to pole-vault after t months of training is given by a mathematical formula. The formula is given below.

H(t) = 17 - 11e^(-0.02t)

We need to find the number of months after which she will be able to vault a height equal to 11 feet. We will substitute the value of height in the given equation.

11 = 17 - 11e^(-0.02t)

11e^(-0.02t) = 17 - 11

11e^(-0.02t) = 6

e^(-0.02t) = 6/11

Now, we will take the natural logarithm on both sides of the equation.

-0.02t = -0.606

t = 0.606/0.02

t = 30.3

Thus, she will be able to vault 11 feet in approximately 30 months.

In triangle QRS, ∠S=67⁰ if ∠R =∠S and ∠Q=46⁰

An angle is a figure in Euclidean geometry made up of two rays that share a vertex, or common endpoint, and are referred to as the sides of the angle. Two planes intersecting at an angle also produces an angle.

A measure of an angle or of a rotation is also referred to as an angle. The ratio of a circular arc's length to radius is known as this quantity. When it comes to a geometric angle, the arc's vertex serves as its center and its sides as its boundaries. When there is a rotation, the arc is defined by the rotation's image and any other point other than the rotation's center.

In triangle QRS,

And from the figure,

∠R=∠S

Therefore,
