If A, B, C, and D are collinear, then
they lie in the same plane. A, B, C,
and D lie in the same plane.
If BD bisects ABC, then D lies in
the interior of ABC. D lies in the
interior of ABC.
The hypothesis of both statements are false.
How to Interpret Collinear Points?1) Collinear points are the points that lie on the same straight line or in a single line. If two or more than two points lie on a line close to or far from each other, then they are said to be collinear,
Thus, if A, B, C, and D are collinear, then they cannot lie in the same plane.
Thus, the hypothesis is not true.
2) When we bisect an angle, it is possible that one of the endpoints of the line may be outside the interior of the bisected angle. Thus, the hypothesis is Not true.

Find the midpoint of FG given F(2, -6) and G(-8, 10)
the midpoint of FG given F(2, -6) and G(-8, 10) = (-3,2)
Solution :
The midpoint calculator will take two coordinates in the Cartesian coordinate system and find the point directly in-between both of them. This point is often useful in geometry.
1. Label the coordinates(x₁,y₁) and (x₂,y₂).
2. Input the values into the formula.
3. Add the values in the parentheses and divide each result by 2.
4. The new values form the new coordinates of the midpoint.
f we have coordinates (x₁,y₁) and (x₂,y₂), then the midpoint of these coordinates is determined by (x₁ + x₂)/2, (y₁ + y₂)/2. This forms a new coordinate you can call (x,y).
Given :
F(2, -6) and G(-8, 10)
FG= (-8+2)/2,(-6+10)/2
FG= (-6/2,4/2)
FG=(-3,2)
the midpoint of FG given F(2, -6) and G(-8, 10) = (-3,2)

Solve for x.
(x+40)°
(3x-17)
(2x-5)
Answer:
x = 27
Step-by-step explanation:
All angles in a triangle add up to 180 degrees
180 = (3x - 17) + (x + 40) + (2x - 5)
Combine like terms.
180 = 6x + 18
Subtract 18 from both sides.
162 = 6x
Divide both sides by 6.
x = 27
Assuming a 5-point difference between the two sample means, which set of sample characteristics is most likely to produce a significant value for the independent-measures t statistic?
A large mean difference and small sample variances. The correct option is B.
What are sample statistics?A statistical measure known as the effect size () assesses the magnitude of the link (numerically) between two variables. The difference between the weights of male and female candidates, for instance, is known as the effect size. If we obtain information on the weights of male and female candidates and discover that men are, on average, heavier than women, for example.
The weight difference between men and women will increase as the effect size increases. Statistic effect size aids in determining whether a difference is real or the result of changing variables. Effect size, power, sample size, and critical significance level are all related to hypothesis testing.
Therefore, a large mean difference and small sample variances. The correct option is B.
The complete options are given below:-
a. A small mean difference and small sample variances
b. A large mean difference and small sample variances
c. A small mean difference and large sample variances
d. A large mean difference and large sample variances

A student believes there is a correlation between the number of texts sent during class and GPA. The student collected data and found that the line of fit can be modeled by the equation ŷ = 3.6 − 0.3x.
Identify and interpret the slope in this scenario.
The slope is −0.3. Starting at 3.6, the GPA will increase by 0.3 for every text sent in class.
The slope is −0.3. Starting at 3.6, the GPA will decrease by 0.3 for every text sent in class.
The slope is 3.6. Starting at 0.3, the GPA will increase by 3.6 for every text sent in class.
The slope is 3.6. Starting at 0.3, the GP will decrease by 3.6 for every text sent in class.
Using linear function concepts, the correct option is given by:
The slope is −0.3. Starting at 3.6, the GPA will decrease by 0.3 for every text sent in class.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, the function is:
y = 3.6 - 0.3x.
The function has a initial GPA of 3.6(student who sends 0 texts), then for each text the student sends, the GPA falls by 0.3(slope of -0.3), hence the correct option is:
The slope is −0.3. Starting at 3.6, the GPA will decrease by 0.3 for every text sent in class.

From the question, the first table is not a function while the other two tables are functions.
How to Identify a Function?
A function is a correspondence or mapping from a first set of numbers, called the domain of the function, to a second set of numbers, called the range of the function, such that for each member of the domain there is exactly one member of the range.
A function is said to be one-to-one if every y value has exactly one x value mapped onto it, and many-to-one if there are y values that have more than one x value mapped onto them. This graph shows a many-to-one function.
4) We see that all the y-values are the same or equal. Thus, we can say that it is not a function because it doesn't match the definition above.
5) Yes the table describes a function because all input values produces a unique output y-value.

Therefore, conclusion can be made that the given relation isn't a function.
Answer:
Not a function.
Step-by-step explanation:
Functions
A function is a special type of relation where each input (x-value) has a single output (y-value).
One-to-one: Each value in the range (y-values) corresponds to exactly one value in the domain (x-values).Many-to-one: Some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).The given function is not a function as the input value of x = -1 has multiple output values of y = 2 and y = -1.

If the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400. how many books on average does each student have?
The number of books taken by each student is 6.
What is an average?Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.
Given that the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400.
The average is calculated by dividing the sum of the total number of items by the total counts of the items.
Average = 14400 / 2400
Average = 6
Therefore, the number of books taken by each student is 6.

Distance that she wants to ride this week = 55.5 miles
Distance she has already ridden so far = 19 miles
Now, we are told that she will ride 5 more days.
If m is the average number of miles she has to ride to meet her goal, then we can say that;
5m + 19 = 55.5
Making m the subject by, we have;
m = (55.5 - 19)/5

The area of an animal pen is 30 square feet. what are the legnths of the pen's sides if the pen has each given shape?
L = 1.3245 is the legnths of the pen's sides .
What is area and perimeter?
Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.
The equation for perimeter is 2L + W = 30 ( I'm assuming that the shed takes up one of the Widths, but you can use the Length if you want, it doesn't matter.)
So W = 30 - 2L.
Area = L x W = L (30 - 2L) = 30L - 2L^2.
This is a quadratic equation, easily graphed as a parabola, with a maximum point at L = 1.3245 .

Answer:
15. x = 4
17. AB = 9
Step-by-step explanation:
15.
Since B is in the middle of AC, AB + BC = AC
So,
x + 5 + 2x - 4 = 13
3x + 1 = 13
3x = 12
x = 4
17.
Since B is in the middle of AC, AB + BC = AC
So,
x + 16 + x + 17 = 19
2x + 33 = 19
2x = -14
x = -7
Going back to the question, it says to find the length of AB.
