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

A zoologist studied the wild cat population of two islands during a four year span - Meow Island and Purr Island. She collected the following data about the population.
1. How would you describe the growth of each island ?
2. Which do you think will be modeled by a linear function ?
Answers
Answer:
Meow Island has a linear function.
Step-by-step explanation:
Meow Island increases by multiply the input by 3 for each coordinate. On the other hand, Purr Island increases by adding 4. Linear functions increase with multiplication, not by addition, and so Meow Island increases linearly.

Repent while there’s still time. Love while you still can. Give till there’s nothing left. Serve with all you’ve got. Go while you’re still able. Share all that you have. Follow hard after God. Live with no regrets. Time is of the essence. If we only have today, there’s still time. Don’t miss this time. Look yourself in the mirror and ask your self - If I died today, would the Lord judge me worthy of eternal life? If the answer is no, then ask him for forgivness. As long as you are really sorry, he will forgive you. If you want to talk, I am here. If you need time alone, then I will leave you alone. If you need a Bible, I can get you one. Follow your heart and never stop doing good. Thank you for reading this, and have a great day. May the good Lord bless you, your family, and the world.

A spherical cantaloupe is cut in half. The visible cross-section has an area of 5252 in2. The volume of the cantaloupe is _____ cm3. Round your answer to the tenths place.
Answers
Answer:
V = 286319.465 cm3
Step-by-step explanation:
First, you have to find the radius to be able to find the volume of a sphere.
The equation for the area of a circle is pi r^2 so you have to so some algebra.
5252 = pi r ^2
5252/pi = r^2
1671.76352 = r^2
sqrt(1671.76352) = r
r = 40.8872048
then you do the equation for the volume of a circle which is 4/3 pi r^3
4/3 pi (40.8872048)^3
4/3 pi 68353.7373
4/3 214739.599
286319.465
V = 286319.465 cm3

Given : Beth owes 17,000 on her car loan. The interest rate on her loan is 4.25% She will be paying this loan off for 4 years.
To find : How much will she pay altogether?
Solution :
Using compound interest formula,
A = P(1 + r)
Where A is the amount
P is the principle P=17,000
P is the rate r=4.25%=0.0425
t is the time t= 4 years
Substitute the value,
Therefore, She has to pay $20078.7 amount.

50% of 152 = 76

75% of 152 = 114
Sorry if im wrong
Answer:
76
38
114
Step-by-step explanation:
50% of 152
= ( 50 / 100 ) x 152
= ( 1 / 2 ) x 152
= 152 / 2
= 76
25% of 152
= ( 25 / 100 ) x 152
= ( 1 / 4 ) x 152
= 152 / 4
= 38
75% of 152
= ( 75 / 100 ) x 152
= ( 3 / 4 ) x 152
= ( 3 x 152 ) / 4
= 3 x 38
= 114
