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
Amelie has a spinner divided into ninths equal sections that are labeled 1 through 9. she wants to compare the theoretical probability and experimental probability as spending an odd number she spends the spinner 12 times and records the results in this list. Drag and drop the answers into the boxes to correctly complete the sentences.
•Theoretical probability of spinning in on number is equal to (blank). The probability of spinning a number is equal to (blank). Therefore the theoretical probability of being a number is (blank) the experimental probability of spelling and odd number.
Choices- 1/9. 1/2. 5/9. 2/3. greater than. less than.
HURRY PLEASE! THANK YOU GUYS
Using the probability concept, it is found that the sentence that describes this situation is given as follows:
Theoretical probability of spinning in on number is equal to 5/9. The probability of spinning a number is equal to 2/3. Therefore the theoretical probability of being a number is less than the experimental probability of spelling and odd number.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these number of outcomes are taken from previous trials, while for a theoretical probability, they are considered before the trials.
From 1 to 9, there are 5 out of 9 odd numbers, hence the theoretical probability is given by:
pT = 5/9 = 0.5555.
Out of the 12 trials, 8 resulted in an odd number, hence the experimental probability is given by:
pE = 8/12 = 2/3 = 0.666.
Hence the sentence is:
Theoretical probability of spinning in on number is equal to 5/9. The probability of spinning a number is equal to 2/3. Therefore the theoretical probability of being a number is less than the experimental probability of spelling and odd number.

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.

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.

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.

You plan to construct a brick wall measuring 14.5 ft. in length, 5.5 ft. high, and 0.5 ft. in width. If a brick measures 6 in. x 4 in. x 2 in. you will need 3,240 bricks.
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.

Two students created a game of dice. they determined that each roll would add the value of the die if it was an odd number. if the roll was even, it would subtract the value of the die.

The expected value for the given experiment is:
E = -0.5
How to get the expected value?For an experiment with the possible events {x₁, x₂, ..., xₙ}, each with the correspondent probability {p₁, p₂, ..., pₙ}, the expected value is defined as:
E = x₁*p₁ + ... + xₙ*pₙ
In this case, all the probabilities are equal to 1/6 (assuming that the dice is fair), then we have:
E = (1/6)*(1 - 2 + 3 - 4 + 5 - 6) = (1/6)*(-3) = -0.5

Answer:

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
