Answer:

Step-by-step explanation:

Each domain value (x-value) of a function has exactly one range value (y-value).

A function can have two or more domain (x-value) having the same range (y-value)

Graph A shows the different domain value (x-values) having exactly one range value (y-value). No x-value has two different y-values.

Therefore, graph A is a function.

I am going to graph the situation on an external graphing utility and show you the answer, it will take a

minute, stay with me.

$m\text{ = }\frac{rise\text{ }}{\text{run}}=\frac{change\text{ in y}}{\text{change in x}}=\frac{3}{1}=3$ $y\text{ = mx+b}\rightarrow\text{ b =-1}$

So the equation of the line is.

$y\text{ =3x -1}$ $y\text{ -1 = m(3-0)}$

If Dante spins the spinner below 75 times, how many times should he expect it to land on "U"?

Fed [463]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete; So, I will solve making assumptions

$Spinner = 10\ segments$

$U = 1$

$n=75$

Required

Number of times to land on U

First, calculate the theoretical probability of U

$Pr(U) = \frac{U}{Spinner}$

$Pr(U) = \frac{1}{10}$

The expected number (E) of time to land on U is then calculated as:

$E = Pr(U) * n$

$E = \frac{1}{10} * 75$

$E = 0.10 * 75$

$E = 7.5$

Approximate

$E = 8$

8 times

Follow the above steps, and you will arrive at your answer
