Please help me with geometry.

Answer:

D.

Step-by-step explanation:

The formula is Sum(n) = (n -2) 180.

The polygon angle sum theorem states that the sum of the measures of the interior angles of an n-gon is (n-2) 180

A polygon is a geometric figure with a finite number of sides in 2D. A polygon's sides are made up of straight-line segments. They are called as sides. The intersection of two line segments is known as the vertex and an angle is generated as result.

The term n-gon refers to polygon with n sides.

A polygon's interior angle is the angle formed between two adjacent sides of the polygon.

We will take a pentagon(5 sides) and then we will try to generalize it to an n-gon(n sides) with the following steps:

The sum of the interior angles of a triangle is 180°

Now, each triangle has the sum of interior angles of 180°,

so (n-2) triangles will have the sum of interior angles of (n-2)×180°.

Therefore, the sum of the measures of the interior angles of an n-gon is (n-2)×180.

Step-by-step explanation:

ANSWER

13.5

EXPLANATION

It was given that, y varies directly as x.

Therefore, the variation equation is of the form:

[tex]y = kx[/tex]

If y is 4.5 when x is 3, then we can substitute to find the constant of variation.

[tex]4.5 = 3k[/tex]

Divide both sides by 3;

[tex]k = \frac{4.5}{3} [/tex]

[tex]k = \frac{3}{2} [/tex]

Hence the equation becomes:

[tex]y = \frac{3}{2} x[/tex]

When x=9,

[tex]y = \frac{3}{2} \times 9 = 13.5[/tex]

Set A represents a function because each element of its domain is paired with a unique element in the range. Set B does not represent a function because it has repeated first elements without unique corresponding second elements.

The question asks which set of ordered pairs represents a function. A function is a special type of relation where each element of the domain (the first element in each ordered pair) is paired with a unique element in the range (the second element in each ordered pair). Analyzing option A, we see that each first element in the set A = {(1, −2), (3, −5), (5, 2), (7, 5)} is unique, which means it represents a function. However, for option B, we have repeated first elements in the set B = {(4, 2), (4, −2), (9, 3), (9, −3)}, which means it does not meet the criteria for a function as the first element, which belongs to the domain, is not mapped to a unique value in the range.

Set up hypotheses as:

[tex]H-0: p=0.60\\H_a: p >0.60[/tex]

(Right tailed test)

Sample proportion p = favourable/total = [tex]\frac{640}{1000} =0.64[/tex]

p difference [tex]=0.64-0.60 =0.04[/tex]

Sample std error = [tex]\sqrt{\frac{pq}{n} } =\sqrt{\frac{0.64(0.36)}{1000} } \\=0.0152[/tex]

Critical value for95% = 1.96

Margin of error = [tex]1.96(0.0152)\\= 0.0298[/tex]

Confidence interval for proportions

=[tex](0.64-0.0298, 0.64+0.0298)\\=(0.6102,0.6698)[/tex]

Since confidence interval does not contain 0.60 we reject null hypothesis.

At 5% significance level we can accept thta proportion >0.60

For this case, we must represent the numbers that are included between -4 and 6. Let "x" be the variable that represents these numbers, then we have:

[tex]-4 <x <6[/tex]

If the set includes -4 and 6 then we have:

[tex]-4\leq x\leq 6[/tex]

Answer:

[tex]{x | -4 <x <6}[/tex] or

[tex]{x | -4\leq x\leq 6}[/tex]

Answer: 18

Step-by-step explanation:

Per a.p.e.x

The area of a triangle can be found using the formula: Area = (base × height) / 2.

The area of a triangle can be found using the formula: Area = (base × height) / 2. To find the area of the triangle shown below, you need to know the length of the base and the height. Once you have those values, you can plug them into the formula to calculate the area.

The range of (w.r)(x) is all real numbers.

The range of (w.r)(x) can be found by substituting the value of x from w(x) into r(x). So, we have:

(w.r)(x) = r(w(x)) = 2 - (x - 2)^2 = 2 - (x^2 - 4x + 4) = 6 - x^2 + 4x.

Therefore, the range of (w.r)(x) is all real numbers.

Student attendance numbers were the same during which two weeks of the workshop? B. weeks 2 and 4

A histogram is the graphical display of data by using bars of different heights. Histograms provide a visual interpretation of numerical data by indicating the number of data points that lie within a range of values. Histogram was first introduced by Karl Pearson in 1891.

Some histograms presented with the independent variable along the vertical axis and dependent variable along the horizontal axis.  The histogram attached below shows the weekly attendance of participants in a school's study skills program. In the histogram the x axis is number of weeks and y axis is number of students in attendance.

According to the histogram attached we can see that in week 1 the Student attendance was 8, in week 2 the Student attendance was 12, in week 3 the Student attendance was 15, in week 4 the Student attendance was 12, in week 5 the Student attendance was 18, in week 6 the Student attendance was 16. Hence the Student attendance numbers are the same during week 2 and 4 of the workshop. Therefore the correct option is B

Student attendance numbers were the same in week 2 and 4

A histogram is a graphical representation of data that uses bars of various heights. By showing how many data points fall inside a certain range of values, histograms provide numerical data a visual interpretation. Karl Pearson initially described the histogram in 1891.

In some histograms, the dependent variable is displayed along the horizontal axis and the independent variable is given along the vertical axis. Participants in a school's study skills program's weekly attendance are depicted in the histogram below. The number of weeks is on the histogram's x-axis and the number of students present is on the y-axis.

GIVEN

The histogram that is attached shows that the student attendance for the first week was 8, for the second week was 12, for the third week was 15, for the fourth week was 12, for the fifth week was 18, and for the sixth week was 16. Thus, the student attendance figures for weeks two and four of the program are identical.
