According to the table, the average number of pools sold per month during this period is 14 (to the nearest tenth)

It is defined as the ratio of summation of all the data to the number of units present in the list. It can also be the middle value, calculated by dividing the total of all the values by the number of values.

The average can also be defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.

It is represented mathematically as;

Average = Sum of Values/Number of Values

Average = total swimming pools sold in six months / number of months

Average = (11 + 10 + 12 + 16 + 15 + 18) / 6

Average = 82/6

Step-by-step explanation:dwd

The initial polynomial result will include several terms, but after simplification, there may only be one or two terms left.

Each polynomial must be considered to be in standard form. The initial multiplication will result in a total of m and n terms since each of the m terms of the first polynomial will be multiplied by each of the n terms of the second.

When the sum is simplified, some of those elements may be combined, resulting in a final product with only one or two terms.

1. 2 × b = 2b . . . . . each has 1 term; the result has 1 term.

2. (x -a)(x +a)  = x² -ax + ax -a² (2×2=4 terms) = x² -a² . . . . the results has 2 terms.

so x3=(9-5)/2=2, y3=(-5/2-3/2)/2=-2.

the coordinates is (2, -2).

The equation of the line that passes through the points (- 6, - 3) and (4, 5) is y = (4 / 5) · x.

In this question we have the knowledge of two points, of which we must derive the equation of a line, whose definition is shown below:

y = m · x + b

Where:

The slope of the line can be determined by secant line formula:

m = Δy / Δx

Where:

First, determine the slope of the line:

m = [5 - (- 3)] / [4 - (- 6)]

m = 8 / 10

m = 4 / 5

Second, determine the intercept of the line:

b = y - m · x

Therefore , the solution of the given problem of trigonometry comes out to be x = nπ where nЄ Z (where n is an integer).

The mathematical field of trigonometry investigates relationships between triangle sides and angles. Because every straight-sided form may be reduced to a collection of triangles, trigonometry is a fundamental concept in all of geometry. The relationships between trigonometry and other branches of mathematics, particularly calculus, real or complex, infinite series, logarithms, and infinite series, are astonishingly intricate.

Here,

In[tex]e^{sinx}[/tex]= In 1

sin x = 0

And when x = "0, 0", "2", we would have that sin x = 0 in [0, 2"]. In general, we would then have that x = n, where n Z, because of the periodicity of sin (where n is an integer).

The value of x on the line segment and the triangle is 17.3 units

From the question, we have the following parameters that can be used in our computation:

A triangle (see attachment for the triangle)

Also from the question, we understand that:

BD bisects ∠ABC

Using the bisector theorem, we have

x/13 = 20/15

Multiply both sides of the equation by 13

So, we have the following representation

13 * x/13 = 20/15 * 13

Evaluate the products

So, we have the following representation

x = 20/15 * 13

Evaluate the other products

So, we have the following representation

x = 52/3

Answer:7 7/8. pounds.

Step-by-step explanation:

Answer: A total of 8 1/3 yards of fabric is needed for both pieces.

Step-by-step explanation: First, you must subtract 1/6 from 4 1/4 to figure out how many yards of fabric is needed for the matching jacket. To do this, you have to find common denominators for each fraction. Since the fractions have a least common denominator of 12, change each fraction to satisfy this new denominator: 1/6 changes to 2/12 and 4 1/4 changes to 4 3/12. Now, you must subtract: 4 3/12 - 2/12 = 4 1/12. Therefore, the matching jacket requires 4 1/12 yards of fabric. Next, add the amount of fabric for the dress (4 3/12) to the amount of fabric for the matching jacket (4 1/12): 4 3/12 + 4 1/12 = 8 4/12. Simplify 8 4/12 to get a final answer of 8 1/3 yards of fabric in total.

A particular dress requires 25/3 yards of fabric for manufacturing is needed for both pieces.

Arithmetic operations are a set of four basic operations to be performed to add, subtract, multiply or divide two or more quantities.

According to the question

A particular dress requires 4 1/4 yards of fabric for manufacturing.

If the matching jacket requires 1/6 yards less fabric.

Jacket need = [tex]4\frac{1}{4} -\frac{1}{6}[/tex]

= [tex]\frac{17}{4} -\frac{1}{6}[/tex]

= [tex]\frac{49}{12}[/tex]

Add the Jacket fabric and dress fabric

Together we need = [tex]\frac{17}{4} +\frac{49}{12}[/tex]

= [tex]\frac{100}{12}[/tex]

= [tex]\frac{25}{3}[/tex]

10.625 pounds of peanuts mixed with almonds priced $5.35 perpound

Weight is measured in pounds. 16 ounces or 0.453592 kilos make up one pound.

Let's name the weight in pounds of almonds and peanuts that we need x.

We are aware that our ultimate goal is to produce 20 pounds of the mixture, which will sell for $4.50 each pound. The mixture will therefore cost 20 * $4.50, or $90, in total.

Additionally, we are aware that peanuts cost $3.75 per pound and almonds cost $5.35 per pound.

As a result, the price of the almonds we use is 5.35x, while the price of the peanuts we use is 3.75(20 - x) = 75 - 3.75x.

We may create an equation since our goal is to produce a mixture that costs $90 in total:

5.35x + (75 - 3.75x) = 90

When we simplify this equation, we get:

1.6x + 75 = 90

75 is subtracted from both sides to produced

1.6x = 15

By multiplying both sides by 1.6, we get:

x = 9.375

To create a mixture that will sell for $4.50 per pound, we must combine around 9.375 pounds of almonds with (20 - 9.375) = 10.625 pounds of peanuts
