The box plot below shows the total amount of time, in minutes, the students of a class surf the Internet every day:
A box plot is shown. The left-most point on the plot is 20 and the right-most point is 95. The box is labeled 35 on the left edge and 60 on the right edge. A vertical line is drawn inside the rectangle at the point 55.
Part A: List two pieces of information that are provided by the graph and one piece of information that is not provided by the graph. (4 points)
Part B: Calculate the interquartile range of the data, and explain in a sentence or two what it represents. (4 points)
Part C: Explain what affect, if any, there will be if an outlier is present. (2 points)
The information that provided by the graph are median and the range. The information that cannot be gotten from the graph is the mode.
The interquartile range is 25.
The outlier would distort the value of the median and mean.
How can a box plot be interpreted?The information that can be derived from the box plot are the minimum value, maximum value, range, median, first quartile and third quartile.
The interquartile range is the difference between the first quartile and third quartile.
Interquartile range = 60 - 35 = 25

Answer:
PART A: You cannot find the mode from the box plot. However, you can find the mean, median, and the range along with outliers.
PART B: 60-35=25 This is the interquartile range.
PART C: The outliers will cause the mean into increase.

What form do planes perpendicular to the z-axis have in spherical coordinates
The cartesian form of planes perpendicular to the z-axis have in spherical coordinates is z = r cosФ.
What is the spherical coordinate?Spherical coordinates, also known as spherical coordinates, are a type of curvilinear coordinate system that is useful for defining locations on a sphere or spheroid.
The conversion of cartesian coordinate to spherical coordinate will be
x = r cosθ sinФ
y = r sinθ sinФ
z = r cosФ
The cartesian form of planes perpendicular to the z-axis have in spherical coordinates is z = r cosФ.

What is the slope of the line containing the points (-2, 1) and (4, -3)?
Step-by-step explanation:
the slope is always the ratio "y coordinate charge / x coordinate change" when going from one point on the line to another.
so, when going from (-2, 1) to (4, -3)
x changes by +6 (from -2 to 4).
y changes by -4 (from 1 to -3).
therefore, the slope is
-4/+6 = -4/6 = -2/3

6x^2-12x-210
What are the x's
Answer:
in the pictureStep-by-step explanation:
× = 7× = 5
HOPE ITS HELP
Answer:
x = -7 and x = 5
Step-by-step explanation:
First, make the problem easier by taking out the common factor (6).
6x² - 12x - 210 -----> 6(x² - 2x - 35)
What two numbers multiply to -35 and add to -2? These two numbers are -7 and 5. You can now write the factored form of the expression.
6(x² - 2x - 35) -----> 6(x - 7)(x + 5)
Finally, find the x's by making each term with x equal to zero.
x + 7 = 0 -----> x = -7
x - 5 = 0 -----> x = 5
The x's are x = -7 and x = 5

Answer:
a. 57.2
b. scalene
Step-by-step explanation:
The lengths of the sides can be found from the coordinates of the vertices using the distance formula. The perimeter of the triangle is the sum of the side lengths.
__
a.The distance formula is ...
d = √((x2 -x1)² +(y2 -y1)²)
sidesThe length of EF is ...
d = √((24 -28)² +(27 -24)²) = √(16 +9) = √25 = 5
The length of FG is ...
d = √((0 -24)² +(24 -27)²) = √(576 +9) = √585 ≈ 24.2
The points E and G lie on the same horizontal line, so the distance between them is the difference of their x-coordinates:
d = 28 -0 = 28 . . . . length of EG
perimeterThe perimeter is the sum of side lengths:
P = EF +FG +GE
P = 5 +24.2 +28 = 57.2
The perimeter of the figure is about 57.2 units.
__
b.The three sides have three different lengths. This makes the triangle a scalene triangle.

Audrey ran 2 1/6 miles yesterday. Today, she ran 1 3/6 miles. Tomorrow, she plans on running 1 4/6 miles less than yesterday and today combined. How many miles will Audrey run tomorrow?
Answer:

What is the volume of the cuboid?The volume of the cuboid is the product of the length, breadth, and height of the given prism.
Volume of cuboid = (length x width x height)
We have given that
Dimensions of a brick wall is given by
Length = 14.5 feet
Width = 0.5 feet
Height = 5.5 feet
Dimensions of a brick is given by
Length = 6 inch
Width = 4 inch
Height = 2 inch
First of all, we will convert the dimensions of a wall from feet into inches.
1 feet = 12 inch
15 feet = 12*15 inch = 180 inch
6 feet = 12*6 inch = 72 inch
We know that volume of a brick wall will be equal to the volume of 'n' bricks, so we can set an equation;
The volume of a brick wall = the volume of 'n' bricks
180 x 72 x 12 = n x 6 x 4 x 2
155520 = n x 48
n = 3240
Therefore, you will need 3,240 bricks.

Adult tickets to the fall play cost 6 and student tickets cost 3 . The drama class sold 25 more student tickets than adult tickets to the fall play. If the class collected 660 from ticket sales, how many student tickets were sold?
Let x be the total number of student tickets sold.
Then, x - 25 is the number of adult tickets sold.
660 = 3x + 6(x - 25)
660 = 3x + 6x - 150
9x = 810
x = 90
Thus, 90 student tickets were sold.
Which table represents a linear function?
Please help I have to take my final
Answer:
#3
Step-by-step explanation:
You can tell if a table is linear, if the slope is constant within the graph. #3 is the only option that has a constant slope. In the others, if you pick different points from that same table the slope changes. That is how you know that is not a linear function.
A linear equation is an equation in which each term has at max one degree. The table that represents a linear function is Table 3. Thus, the correct option is 3.
A linear equation is an equation in which each term has at max one degree. Linear equations in variables x and y can be written in the form
y = mx + c
Linear equation with two variables, when graphed on a cartesian plane with axes of those variables, gives a straight line.
For the table to represent a linear function, the function must have a constant slope between any two points.
For the third table, the slope between the first two points is,
[tex]m = \dfrac{(- 10 + 2)}{(2 - 1)}[/tex]
[tex]m = - 8[/tex]
The slope between the last two points is,
[tex]m = \dfrac{(- 18 + 10)}{(2 - 1)}[/tex]
[tex]m = - 8[/tex]
Hence, the table that represents a linear function is Table 3. Thus, the correct option is 3.

Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 9) would represent a height of 9 inches after 0 hours.
A function assigns the values. The list of 6 ordered pairs to show the height of the candle inches are (1,8.5), (1,8), (1,7.5), (1,7), (1,6.5), and (1,6).
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The rate at which the candle burns down is 0.5 inches per hour. Now, if we substitute the value of the point (0,9) in the function of a line, and the rate as well, we will get,
y = mx +c
9 = -0.5(0) + c
c = 9
Now, the equation that can represent the height of the candle at any hour after it is lit will be,
y= -0.5x+9
substitute the value of x as 1, 2, 3, 4, 5, and 6 to get the value of y and form ordered pairs.
y=-0.5(1)+9 = 8.5 inches ⇒ (1,8.5)y=-0.5(2)+9 = 8 inches ⇒ (1,8)y=-0.5(3)+9 = 7.5 inches ⇒ (1,7.5)y=-0.5(4)+9 = 7 inches ⇒ (1,7)y=-0.5(5)+9 = 6.5 inches ⇒ (1,6.5)y=-0.5(6)+9 = 6 inches ⇒ (1,6)Hence, the list of 6 ordered pairs to show the height of the candle inches are (1,8.5), (1,8), (1,7.5), (1,7), (1,6.5), and (1,6).
