C. (-1, 2) and (4, 7)
Step-by-step explanation:
It may be simplest just to try the answer choices.
We notice that y = x+3 is not satisfied by the points in choices A or D, so those can be eliminated.
__
The second equation can be written in vertex form as ...
y = (x -1)^2 -2
This equation is not satisfied by the points of choice B.
Using (-1, 4) (from choice B), we get 4 = (-1-1)^2 -2 = 4-2 = 2 . . . FALSE.
However it is a good match for the points of choice C.
Using (-1, 2) (from choice C), we get 2 = (-1-1)^2 -2 = 4 -2 = 2 . . . True
The appropriate choice is ...

Tanya wants to test the theory that the exterior angles of a
triangle add up to 360°. She draws triangle ABC and finds all
the angles in the triangle.
PLEASE HELP!!
Answers
Answer:
[tex]f + e + d = 360^o[/tex]
Step-by-step explanation:
The question is incomplete, as what is required is not stated and the triangle is not given.
So, I will solve generally.
The proof is as follows (see attachment for triangle)
From the attachment, we have:
[tex]a + f = 180[/tex]
[tex]b + e = 180[/tex]
[tex]c + d = 180[/tex]
Make f, e and d the subject
[tex]f = 180 - a[/tex]
[tex]e = 180 - b[/tex]
[tex]d = 180 - c[/tex]
Add up the equations
[tex]f + e + d = 180 -a + 180 - b + 180- c[/tex]
Collect like terms
[tex]f + e + d = 180 + 180+ 180-a- b - c[/tex]
[tex]f + e + d = 540-a- b - c[/tex]
We have:
[tex]f + e + d = 540-(a+ b + c)[/tex]
[tex]a + b + c \to 180[/tex] --- angles in a triangle
So, we have:
[tex]f + e + d = 540-180[/tex]
[tex]f + e + d = 360^o[/tex] --- proved

The table shows the probability distribution of siblings of students in a high school with 1500 students. What is the expected value for the number of siblings of a randomly chosen student?
A. 2.5
B. 1.29
C. 1.08
D. 1.11
Answers
The expected value for the number of siblings of a randomly chosen student is 1.11.
What is expected value mean?"In a probability distribution, the weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value".
For the given situation,
The table shows the probability distribution of siblings of students in a high school with 1500 students.
For number of siblings = 0, Probability = 0.18.
For number of siblings = 1, Probability = 0.65.
For number of siblings = 2, Probability = 0.09.
For number of siblings = 3, Probability = 0.05.
For number of siblings = 4, Probability = 0.02.
For number of siblings = 5, Probability = 0.01.
The formula for expected value mean, E(x) = ΣxP(x)
[tex]E(x)=(0)(0.18)+(1)(0.65)+(2)(0.09)+(3)(0.05)+(4)(0.02)+(5)(0.01)[/tex]
⇒ [tex]E(x)=1.11[/tex]
Hence we can conclude that the expected value for the number of siblings of a randomly chosen student is 1.11.

the slope is 33-15/ -6-(-2)= 18/-4=-9/2
equation is y=mx+b where m is slope and b is y intercept
so plugging values in we get

Lalasa and Yasmin are designing a triangular banner to hang in the school gymnasium. They first draw the design on paper. The triangle has a base of 5 inches and a height of 7 inches. If 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, what will the area of the actual banner be? A 52.5 ft2 B 17.5 ft2 39.375 ft2 D 78.75 ft2
Answers
Find the actual Dimensions of the triangle.
Multiply the size of the triangle on paper by 1.5 feet per inch:
Width = 5 x 1.5 = 7.5 feet.
Height= 7 x 1.5 =10.5 feet
Area of a triangle is 1/2 x base x height:
Area = 1/2 x 7.5 x 10.5 = 39.375 square feet.
Answer: 39.375 square feet.
The area of the actual banner is 39.375 feet²
What is scaling?
Scaling is used to increase or decrease the size of a figure so as to create an image.
Given that 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, hence:
Base = 5 in * 1.5 feet per in = 7.5 feet
Height = 7 in * 1.5 feet per in = 10.5 feet
Area of the actual banner = (1/2) * 7.5 * 10.5 = 39.375 feet²
The area of the actual banner is 39.375 feet²

The volume of both of these trapezoidal prisms is 24 cubic units. Their heights are 6 and 8 units, as labeled. What is the area of a trapezoidal base of the prism with a height of 6 units?
Answers
Answer:
area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively
Step-by-step explanation:
Let us first be aware of formula of volume for any regular geometrical figure.
Fundamental formula for volume for any regular geometrical figure is.
volume = area of cross section of object* height of object (A)
In the problem stated area of cross section of object will be area of a trapezoidal base.
Given in the question is
Volume of both the trapezoidal prisms = 24 cubic units
*************************************************************************************
For prism with height 6 unit
Substituting the value of height and volume in formula for trapezoidal prisms
24 = 6 * area of a trapezoidal base
=> area of a trapezoidal base = 24/6 = 4 square units
*************************************************************************************
For prism with height 8 unit
Substituting the value of height and volume in formula for trapezoidal prisms
24 = 8 * area of a trapezoidal base
=> area of a trapezoidal base = 24/8 = 3 square units
*************************************************************************************
Therefore area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively.
