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

What is a histogram?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.

The polygon angle sum theorem states that the sum of the measures of the interior angles of an n-gon is
n-2/180
(n-1) 180
180/n-1
(n-2) 180
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
What is a polygon or an n-gon?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.
What are the interior angles of a Polygon or an n-gon?A polygon's interior angle is the angle formed between two adjacent sides of the polygon.
How to find the sum of the measures of the interior angles of an n-gon?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:
In the figure let's take the vertex B and connect all the other vertices to it.Now, look there are a total of 3 triangles formed inside the pentagon.So, now we can say if we add connect all the vertices of an n-gon from a random vertex it will produce a total of (n-2) triangles in it.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.

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.
Explanation: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.

Answer:
1. The number zero (0) is the additive identity for real numbers as adding it to any real number doesn't change the number.
2. a(b+c) = ab + ac or a(b-c) = ab-ac is the distributive property as a is distributed to b and then c.
3. An Equation with more than one variables is called literal equation. The variables are known in literal equations. These kind of equations are usually used to represent time, distance etc.
4. The number 1 is the multiplicative identity for real numbers as multiplying any real number with 1, other than zero, doesn't change the number.
5. The reciprocal of a number such that x is a number other than zero and 1/x is the reciprocal and the product of x and 1/x is equal to 1 then 1/x is called the multiplicative inverse of x.
PLEASE HELP ASAP !!!! Drag each interval to a box to show if the function is increasing,decreasing,or neither over that interval. -9<×<-6, -6<×<-4, -4<×<-1, -13<×<-12, -12<×<-9. Increasing, Decreasing, Neither Increasing or Decreasing
Answer:
[tex]-13 <x <-12[/tex] Neither Increasing or Decreasing
[tex]-12 <x <-9[/tex] Increasing
[tex]-9 <x <-6[/tex] Decreasing
[tex]-6 <x <-4[/tex] Increasing
[tex]-4 <x <-1[/tex] Neither Increasing or Decreasing
Step-by-step explanation:
To know if the graph of a function is growing or decreasing you must use the graph to verify what happens when x increases.
If when x increases y decreases, then the function is decreasing.
If when x increases y increases, then the function is growing.
Let's look at the
First interval.
[tex]-13 <x <-12[/tex] Note that the value of y is always equal in this interval, therefore the function is not increasing or decreasing.
Second interval
[tex]-12 <x <-9[/tex]
Note that when x increases from -12 to -10, the value of y increases from y = 1 to y = 3.
Then the function is increasing in this interval
Third interval
[tex]-9 <x <-6[/tex]
Note that when x = -9 y= 8, but when x approaches -6 then y approaches 7.
Therefore in this interval the function is decreasing.
Fourth interval
[tex]-6 <x <-4[/tex]
When x = -6 y = 7 and at the end of the interval when x = -4 then y = 11
The function is increasing.
Fifth interval
[tex]-4 <x <-1[/tex]
The value of y remains constant throughout the interval. So the function is not increasing and it is not decreasing
Consider the quadratic function f(x) = –2x2 + 4x – 2. Find the y-intercept and the equation of the axis of symmetry.
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = - 2x² + 4x - 2
To find the y- intercept set x = 0
f(0) = 0 + 0 - 2 = - 2 ← y- intercept
The equation of the axis of symmetry is of the form x = c
where c is the value of the x- coordinate the line goes through.
Given the equation in standard form
with a = - 2, b = 4 then the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex] = - [tex]\frac{4}{-4}[/tex] = 1
Equation of axis of symmetry is x = 1
Answer:
The y-intercept is -2
The equation of the axis of symmetry is x = 1
Step-by-step explanation:
* Lets revise the general form of the quadratic function
- The general form of the quadratic function is f(x) = ax² + bx + c,
where a, b , c are constant
# a is the coefficient of x²
# b is the coefficient of x
# c is the y-intercept
- The meaning of y-intercept is the graph of the function intersects
the y-axis at point (0 , c)
- The axis of symmetry of the function is a vertical line
(parallel to the y-axis) and passing through the vertex of the curve
- We can find the vertex (h , k) of the curve from a and b, where
h is the x-coordinate of the vertex and k is the y-coordinate of it
# h = -b/a and k = f(h)
- The equation of any vertical line is x = constant
- The axis of symmetry of the quadratic function passing through
the vertex then its equation is x = h
* Now lets solve the problem
∵ f(x) = -2x² + 4x - 2
∴ a = -2 , b = 4 , c = -2
∵ The y-intercept is c
∴ The y-intercept is -2
∵ h = -b/2a
∴ h = -4/2(-2) = -4/-4 = 1
∴ The equation of the axis of symmetry is x = 1

What is the mean weight of the polar bears?
Answer:
410 kilograms
Step-by-step explanation:
The mean is another way to say average.
Add the weights of all the polar bears together
3,280 kilograms total.
Then divide by the total number of bears
3,280 / 8 = 410
Answer:
Mean=410
Step-by-step explanation:
Given that the table shows the weights, in kilograms, of 8 polar bears.
Now we need to find about what is the mean weight of the polar bears.
So we just need to add all the weights then divide the sum by 8 to get the mean weight.
[tex]Mean=\frac{453+553+471+358+467+262+352+364}{8}[/tex]
[tex]Mean=\frac{3280}{8}[/tex]
[tex]Mean=410[/tex]
Hence final answer is Mean=410.

If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w.r) (x)?
The range of (w.r)(x) is all real numbers.
Explanation: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.
