Answer:
a. False
b. False
Step-by-step explanation:
a. The experimental probability or relative frequency is based on actual results from an experiment and may differ from the theoretical probability of an event occurring.
This statement is false because, both the experimental and theoretical probability must agree for the probability of the event occurring to the true.
If both do not agree, that means we have two different probabilities for a s ingle event, which cannot be true. So, the statement is false.
b. The Experimental Probability will be almost the same as the Theoretical Probability as the number of trials of an experiment is very small
This statement is also false because, the experimental and theoretical probabilities only agree when the number of trials of an experiment become large. For small number of trials, both the experimental and theoretical probabilities might not agree.

Step-by-step explanation:
write the equation of the line in slope intercept form that passes through the points (4,6) and (10,0)
Answer:
y = -x + 10
Step-by-step explanation:
Find the slope:
0 - 6 / 10 - 4 = -6/6 = -1.
Put it in point-slope form:
y - 0 = -1(x - 10)

point B is the image of the point A when A is rotated 90° counterclockwise around the origin
point B must be the same ________ from the origin as point A
Answer:
distance
Step-by-step explanation:
Point B must be the same distance from the origin as point A.
What is Rotation?Rotation is a kind of geometric transformation where a figure or point is rotated by a certain degrees about a given point.
Given that,
Point B is the image of the point A when A is rotated 90° counterclockwise around the origin.
A point P(x, y) after the rotation of 90°counterclockwise around the origin is P'(-y, x).
So the x coordinate changes to the negative of y coordinate and y coordinate changes to x coordinate.
Distance between P(x, y) from origin (0, 0) is √(x² + y²)
Similarly the distance P'(-y, x) from origin (0, 0) is √((-y)² + x²) = √(x² + y²)
Hence they are at the same distance.

Simplify the inequalities and match them with the graphs that represent them.
(look at the screen shot)
Answers:
Graph A matches with 7x < 42Graph B matches with x+1 < 8Graph C matches with 3x > 15Graph D matches with 2x > 12===================================================
Explanation:
For each inequality given, we need to isolate x. We'll solve for x in pretty much the same way we solve an equation. So if we wanted to solve 2x = 12, we would divide both sides by 2 to get x = 6.
Similarly, solving 2x > 12 would lead to x > 6. The inequality sign does not flip. It only flips if you divide both sides by a negative number.
The graph of x > 6 has an open hole at 6 and shading to the right. So that matches with graph D.
---------------------
Solving 7x < 42 leads to x < 6 when we divide both sides by 7. The graph has the open hole at the same endpoint of 6, but now the shading is to the left. This shows all values smaller than 6. Therefore 7x < 42 matches with graph A.
---------------------
We have 3x > 15 match with graph C because that inequality is the same as x > 5, after we divide both sides by 3. We have an open hole at 5 and shading to the right.
---------------------
Lastly, the inequality x+1 < 8 solves to x < 7. We'll have an open hole at 7 and shading to the left. This describes graph B.
Any time you see an open hole, it means "do not include this value as part of the solution set". For instance, with x < 7, we have x = 7 as the open hole. This is because 7 < 7 is a false statement. A number cannot be smaller than itself.

How to depict the figure?From the complete information, the triangle ABC is reflected over the y axis.
The vertices of the triangle are A(1, 1), B(3, 4) and C(3, 1). The vertices of the images are A(1, 1) = A'(-1, 1). B(3, 4) = B(-3, 4) ans C(3, 1) = C'(-3, 1).
In conclusion, the figure that shows a reflection of pre-image ABC over the y-axis is the third figure.

PLEASE HELP!! A circle is divided into three central angles that have measures in the ratio 2:13:15. find the measure of the largest angle.
Answer:
First angle = 24'
Second angle = 156'
Third angle = 180'
Step-by-step explanation:
Given:
Ratio of circles angle = 2:13:15
Find:
All three angle
Computation:
Sum of all angle from center = 360'
So,
First angle = 360[2/(2+13+15)]
First angle = 360[2/(30)]
First angle = 24'
Second angle = 360[13/(2+13+15)]
Second angle = 360[13/(30)]
Second angle = 156'
Third angle = 360[15/(2+13+15)]
Third angle = 360[15/(30)]
Third angle = 180'
