A teetotum is a spinning top that has an equal probability of landing on each side. The expected value of one

Mathematics

Probabilities are used to determine the chances of events

The true statement is (c) the teetotum could land on the number 10

<h3>How to determine the true statement</h3>

From the question, we understand that the spinning top is divided into 12 equal segments

This means that the possible outcomes of the spin is from 1 to 12

Hence, the true statement is (c) the teetotum could land on the number 10

First we distribute \frac{1}{5} into n and -\frac{1}{7}.

\frac{1}{5} * n =  \frac{1}{5} n
\frac{1}{5}  *  -\frac{1}{7}  = - \frac{1}{35}

That makes the left side of the equation 

\frac{1}{5} n -  \frac{1}{35} =  \frac{1}{6} n

Now we subtract \frac{1}{5}n from \frac{1}{6} n, which makes \frac{1}{30}

Now the equation is 

-\frac{1}{35} =  -\frac{1}{30n}

Our goal is to isolate n, so we both sides by 30

30* -\frac{1}{35} = - \frac{1}{30}n * 30 

That will make the equation 

- \frac{30}{35} = -n

We multiply -1 on both sides of the equation:

\frac{30}{35} = n

Finally we simplify \frac{30}{35}, which makes \frac{6}{7}

So the answer is n =  \frac{6}{7}

Point A(–4, 2) is reflected over the line x = 3 to create the point A'. What are the coordinates of A'?
iragen [17]
A ( - 4, 2)
Reflected over x = 3.
x = 3 is a vertical line, the point (-4, 2) is 7 units on the left side of the vertical line. When you reflect across the line to the right side we need to be 7 units away from the vertical line on the right side. 3 + 7 = 10
The x value would be 10. (10, 2)

What are line segments?
laiz [17]

Answer:

In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints
