A spinner marked off in seven equal-sized regions, numbered 1, 2, 3, 4, 5, 6, and 7, is spun twice. Let the random variable X be the nonnegative difference between the numbers of the regions where the pointer stops, and define a probability mass function g(x)=P(X=x). a) State the range of X. b) Write g as a set of ordered pairs. c) Draw a probability distribution as a histogram. d) Find g(5), and explain what this number represents. e) Find μ, and explain what this number represents.
Answers
Step-by-step explanation:
To find - a) State the range of X.
b) Write g as a set of ordered pairs.
c) Draw a probability distribution as a histogram.
d) Find g(5), and explain what this number represents.
e) Find μ, and explain what this number represents.
Proof -
a.)
Range of X = { 0, 1, 2, 3, 4, 5, 6 }
b.)
(0, 7/49), (1, 12/49), (2, 10/49), (3, 8/49), (4, 6/49), (5, 4/49), (6, 2/49)
c.)
The graph is as follows :
d.)
The value of g(5) is 6/49
It represents the probability of the difference of the two spins is 5.
e.)
mean, μ = 2.29
It represents the average value of the spins

[tex] - 3 \leqslant x < 2[/tex]T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released. The average rate of change in T(d) for the interval d = 4 and d = 10 is 0. Which statement must be true?The same number of tickets was sold on the fourth day and tenth day.No tickets were sold on the fourth day and tenth day.Fewer tickets were sold on the fourth day than on the tenth day.More tickets were sold on the fourth day than on the tenth day.
Answers
Answer:
The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
Given, T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released.
The average rate of change in a function with respect to the independent variable gives the value of change in a particular period.
If average rate of change in T(d) for the interval d = 4 and d = 10 is is 0 , that means nothing has been changed in the number of tickets sold on 4th day and 10th day after the film release.
Hence, the correct statement is "The same number of tickets was sold on the fourth day and tenth day."
Answer:
In simpler terms, for the edge answer;
A. The same number of tickets was sold on the fourth day and tenth day.

Slope is 1 and (-2, -1) is on the line.
Answers
Answer:
You can’t find the slope of a line if only given one point. If you had a visual representation of the line such as a graph or a table you could find a second point and then use the formula for slope, y = (y2-y1) / (x2-x1).
Imagine a single point on the xy graph. You could take a random point elsewhere from an infinite number of points and would be able to draw a line and find the slope. This means there could be an infinite number of different slopes for one point. One point on an unknown line is not enough information to determine the slope of its line without a graph or a table.

Thomas, a waiter at a local restaurant, is paid $ 4 an hour plus tips. His friend Marie works at a local bookstore for $12 an hour. Marie and Thomas worked the same number of hours. If Thomas made $120 in tips and both made the same amount of money, how many hours
Please just write the equation out.
Answers
Let x be the tips
Let t be Thomas
Let m be Marie’s pay
t=4h+x
(plug in 120 for x)
t=4h+120
——————————————
m=12h
(They made same amount of money working the same amount of hours)
4h+120=12h
120=8h

Need help on #9 and #10 please ASAP. Was busy with a family emergency and missed my class on this.
Answers
Answer:
#9
given, angle BOD = 95 degree
and angle COD = 35 degree
assume that, angle BOC = x degree
so, angle BOC + angle COD = angle BOD
or, x + 35 degree = 95 degree
so, x = 95 degree - 35 degree = 60 degree
so, angle BOC = 60 degree
#10
given, angle AOC = right angle = 90 degree
and angle AOB = 30 degree
assume that, angle BOC = y degree
so, angle AOB + angle BOC = angle AOC
or, 30 degree + y = 90 degree
so, y = 90 degree - 30 degree = 60 degree
so, angle BOC = 60 degree

A jar has 20 marbles: 3 green, 12 blue, 5 red.
What is the probability of randomly choosing a red and then a green marble (keep the red marble when you choose it)?
Answers
Probability is defined as the likelihood or the certainty that an event is going to occur or happen.
The probability of randomly choosing a red and then a green marble is [tex]3/76[/tex].
The total number of marbles = 20
The number of green marbles= 3
The number of blue marbles = 12
The number of red marbles = 5
The probability of choosing a red marble = Number of red marbles / Total number of marbles
= 5/20
In simplest fraction form = [tex]\frac{1}{4}[/tex]
We are told in the question that you keep the red marble you choose, So this means the total number of marbles left reduces to 19
The probability of choosing a green marble is = Number of green marbles / New total number of marbles
= 3/19
Therefore, the probability of randomly choosing a red and then a green marble is
P (Red) x P(Green)
= 1/4 x 3/19
= [tex]3/76[/tex]
