The form of the partial fraction decomposition of the given function is:

[tex]\frac{A}{x+5}+\frac{B}{x-4}[/tex]

To find the form of the partial fraction:

The rational expression given is: [tex]\frac{x-20}{x^2+x-20}[/tex]

Factor the provided rational expression's denominator:

[tex]\begin{aligned}\frac{x-20}{x^2+x-20} &=\frac{x-20}{x^2+5 x-4 x-20} \\&=\frac{x-20}{x(x+5)-4(x+5)} \\&=\frac{x-20}{(x+5)(x-4)}\end{aligned}[/tex]

Apply the partial fraction decomposition method now:

[tex]\begin{aligned}\frac{x-20}{x^2+x-20} &=\frac{x-20}{(x+5)(x-4)} \\&=\frac{A}{x+5}+\frac{B}{x-4}\end{aligned}[/tex]

Therefore, the form of the partial fraction decomposition of the given function is:

[tex]\frac{A}{x+5}+\frac{B}{x-4}[/tex]

There are 20 possible combinations are there for spring formal committees.

Combination:

The process of determining the number of ways in which r objects can be selected from n distinct objects without regard to the order in which they are selected. Such selections are called combinations.

[tex]^nC_r=\frac{n!}{(n-r)!r!}[/tex]

Where

n refers the total number of ways

r refers the selected one

Given,

There are six members on a student council.

Three of these members will serve on a spring formal committee.

Here we need to find the possible number of members in spring formal committees.

We know that the value of,

n = 6

and r = 3

So, apply the values on the formula,

Then we get,

[tex]^6C_3=\frac{6!}{(6-3)!3!}[/tex]

[tex]^6C_3=\frac{6!}{3!3!}[/tex]

⁶C₃ = 720/36

⁶C₃ = 20

Therefore, the resulting value is 20.

Therefore, there are 20 possible combinations are there for spring formal committees.

Answer:

$4.60

Step by Step:

First, you have to subtract $20 from $6.20 which is the change you got back. Once you remove that, you will get $13.80, the actual amount of all three pairs of socks. Now, you have to figure out how much each pair of socks is. So you need to divide 13.80 by 3 which is $4.60. So each pair of socks was $4.60

Answer:

$7.95

Step-by-step explanation:

The equation c = 7.95b represents the total cost of the boxed lunches

c represents the total cost

b represents the number of boxed lunches

To find the total cost of multiple items, you generally multiply the cost of a single item by the number of items there are.

Using this, we can find the cost per item is 7.95 dollars, or 7 dollars and 95 cents.

The probability is 1/4 that the winners will be wearing numbers 2, 4, and 7.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We have been given that a group of 12 dance competition contestants is wearing the numbers 1 through 12.

To determine the probability that the winners will be wearing numbers 2, 4 and 7

Here are favorable outcomes that the contestants wearing numbers 2, 4, and 7

So the number of favorable outcomes = 3

And there is a total number of outcomes = 12

Required probability = 3/12

Required probability = 1/4.

Thus, the probability is 1/4 that the winners will be wearing numbers 2, 4, and 7.

Subtracting the maximum sodium intake from the intake of the cereal bar, you can eat amounts of sodium less than 2,175 mg of sodium the rest of the day.

From the text, the intake has to be less than 2300 mg. From the table, each cereal bar has 125 mg of sodium.

You eat one cereal bar, hence:

2300 - 125 = 2,175.

You can eat amounts of sodium less than 2,175 mg of sodium the rest of the day.

The sample mean of snowfalls in the 18 midwestern cities of the United States is 24. This is calculated by applying the formula of arithmetic mean or average to the given sample of data.

What is arithmetic mean?

An arithmetic mean is examined as very similar to an average. Mathematically, it is obtained by dividing the sum of all objects by the total number of objects.

Calculation of the sample mean for given data

Given the total number of cities = 18

The total amount of snow falls = 20 + 40 + 31 + 7 + 15 + 29 + 25 + 20 + 17 + 32 + 28 + 12 + 34 + 29 + 20 + 17 + 33 + 23

The sample mean = total amount of snowfalls / total number of cities

= 432 / 18

= 24

Hence, the sample mean of the given data is 24.

For the given graph, we have that:

a) It is not a function.

b) The function is discrete.

c) The domain is {-5,2} and the range is all real values.

A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.

For this problem, we can see that it is not a function, as the values of x = -5 and x = 2 are mapped to multiple values of y.

For this problem, the function is defined only for x = -5 and x = 2, which are integer values, hence it is a discrete function.

Thus, the domain is {-5,2} and the range is all real values.

Student's mean score of the class is 80.6.

Mean:

Mean or the average of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

Given,

A student receives test scores of 62, 83, and 91. the student's term project score is 88 and her homework score is 76. each test is worth 20% of the final grade, the term project is 25% of the final grade, and the homework grade is 15% of the final grade.

Here we need to find the student's mean score in the class.

First, we have to convert the percentage into decimal,

Then

=> 20% = 0.20

=> 25% = 0.25

=> 15% = 0.15

Then we have to find the scores from it,

Test A is 0.20 of the total and scores 62.

Test B is 0.20 of the total and scores 83.

Test C is 0.20 of the total and scores 91.

Project F is 0.25 of the total and scores 88.

Work H is 0.15 of the total and scores 76.

Multiply across:

=> A = (0.2 * 62) = 12.4

=> B = (0.2 * 83) = 16.6

=> C = (0.2 * 91) = 18.2

=> F = (0.25 * 88) = 22

=> H = (0.15 * 76) = 11.4

Now we have to add all these values to find the mean,

=> A + B + C + F + H

=> 12.4 + 16.6 + 18.2 + 22 + 11.4

=> 80.6

Therefore, the mean of that student is 80.6

To solve the inequality, multiply both sides by -7 and flip the inequality direction. The solution is n  ≤  -21 or (∞, -21]

Tips to solve linear inequalities:

Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis (  or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.

Example:  x ≥ 2 can be written as [2, ∞), while

                x > 0 is written as (2, ∞)

The given problem:

-n/7 ≥ 3

Multiply both sides by -7. Since we multiply it by a negative number, flip the inequality.

-n/7 . (-7) ≤ 3 . (-7)

n  ≤  -21

Using the interval notation, the solution is (∞, -21]

AB = 15, AC   = 14, BC = 8  

PQ = 8 , QR = 24,  PR = 8

The perimeter is the distance around the object. For example, your house has a fenced yard. The perimeter is the length of the fence. If the yard is 50 ft × 50 ft your fence is 200 ft long.

Perimeter of Δ ABC = Length of AB + Length of BC + Length of AC.

Perimeter of ΔABC = (2x + 7) + (2x) + (2x + 6) = 6x + 13

Perimeter of ΔPQR = (2x) + (3x + 9) + (2x) = 7x + 9

So, 6x + 13 = 7x + 9

 Therefore, x = 4

AB = 2(4) + 7 = 15             PQ = 2(4) = 8

AC = 2(4)+6     = 14          QR = 3(5) + 9 = 24

27/31 ounce of red paint should she really have to make 3 fluid ounces of purple paint.

Any arithmetic operation involving two or more fractions, such as addition or subtraction, is achievable if the denominators of both fractions are equal. This is referred to as the common denominator. A common denominator is an integer that has at least one element in common with both denominators other than 1.

Given:

3 /10 red + 11 /15 blue  makes 1 1/30 purple

Get a common denominator of 30

3/10 * 3/3 = 9/30  red

11/15 *2/2 = 22/ 30  blue

1  1/30 = 31/30   purple

the amount of paint required to make 3 fluid ounce of purple color of paints:
