Consider a small ferry that can accommodate cars and buses. The toll for cars is $3, and the toll for buses is $10. Let X and Y denote the number of cars and buses, respectively, carried on a single trip. Suppose the joint distribution of X and Y is as given in the table below.
y
p(x,y) 0 1 2
x 0 0.025 0.015 0.010
1 0.050 0.030 0.020

3 0.150 0.090 0.060
4 0.100 0.060 0.040
Compute the expected revenue from a single trip. (Round your answer to two decimal places.)
Answers
Answer:
Expected revenue from the single trip is $ 13.14
Step-by-step explanation:

1 0.050 0.030 0.020 0.1

h(y) 0.325 0.27 0.18
E (x+Y) = E(X) +E(Y)
E(X)= ∑ xi g(x)i
= ( 0*0.05) + (1*0.1) + (2* 0.24) + (3*0.3) + (4*0.2)
= 0 + 0.1+ 0.48 + 0.9+0.8
=2.28
E(Y)= ∑yi h(y)
= (0* 0.325) + (1*0.27) + (2*0.18)
= 0 +0.27+ 0.36
= 0.63
E (x+Y) = E(X) +E(Y)
= 2.28 + 0.63
= 2.91
But the equation is 3x+ 10y
E(3x+ 10y)= 3E(x) + 10 E(y)
= 3(2.28) + 10 (0.63)
= 6.84 +6.3
= 13.14

Al functions have an independent variable.
0 The range ofa function includes its domain
DA vertical line is an example ofa functional relationship.
O A horizontal line is an example of a functional relationship.
O Each output value of a function can correspond to only one input value.
Answers
Answer:
A horizontal line is an example of a functional relationship.
All functions have an independent variable.
All functions have a dependent variable (At least).
Step-by-step explanation:
By description, a relation is a purpose if each input condition has one and only one output value.
A function has at least a secondary variable and an autonomous variable. For instance, given a function:
Y=X
The secondary variable is "y" and the autonomous variable is "x".
The Field of the role is the collection of potential input values and the Range is the collection of potential output values,
Vertical lines have an irregular slope. Since the value of "x" never varies, an upward line is not an illustration of a functional relationship.
In the matter of Horizontal lines, for any x-value, you get the equivalent y-value. These are described as Constant functions.

52% of all Americans are home owners. If 45 Americans are randomly selected, find the probability that a. Exactly 21 of them are are home owners. b. At most 24 of them are are home owners. c. At least 23 of them are home owners. d. Between 20 and 24 (including 20 and 24) of them are home owners.
Answers
Answer:
0.0918 ; 0.6277 ; 0.6064; 0.5055
Step-by-step explanation:
Given that :
Proportion of home owners : p = 0.52
Number of trials = 45
Using binomial distribution formula :
P(x =x) = nCr * p^x * (1 - p)^(n-x)
A.) probability that exactly 21 are homeowners :
P(x = 21) = 45C21 * 0.52^21 * (1 - 0.52)^(45 - 21)
P(x = 21) = 45C21 * 0.52^21 * 0.48^24
P(x = 21) = 3773655750150 * 0.52^21 * 0.48^24
P(x = 21) = 0.0918
b. At most 24 of them are are home
Using the binomial probability to save computation time.
P(x ≤ 24) = p(0) + p(1) +.... + p(24)
P(x ≤ 24) = 0.6277
C.) At least 23 of them are home owners.
P(x ≥ 23) = p(23) + p(24) +... + p(45)
P(x ≥ 23) = 0.6064
d. Between 20 and 24 (including 20 and 24) of them are home owners.
P(20 ≤ x ≤ 24) = p(20) + p(21) + p(22) + p(23) + p(24)
P(20 ≤ x ≤ 24) = 0.0711 + 0.0918 + 0.1084 + 0.1175 + 0.1167
P(20 ≤ x ≤ 24) = 0.5055
Patty’s dog Socks eats 15 ounces of dry dog food a day. How many days will a 30-pound bag last? Is this more or less than a month? Explain. Remember, there are 16 ounces in a pound.
Answers
Answer: 32 days. This is more than a month.
Step-by-step explanation:
First, convert the 30 pound bag into ounces. To do this you just need to multiply 30 by 16. You will get 480 ounces (so one bag has 480 ounces of food in it. Then, just divide that by the ounces eaten by Socks in a day. 480/15 is 32. So one bag of food lasts 32 days. At the most, one month can have 31 days in it so this bag will last for more than a month. Hope this helps!

An insurance company charges Ted E. Bear $1400 per year for insurance on his home. The company has predicted that there is a 10% chance that Ted will make a claim on the policy of $5000. Create a probability distribution and determine what the insurance company can expect to make on this policy, on average?
Answers
Answer:
$900
Step-by-step explanation:
The given parameters are;
The amount Ted pays per year for insurance on his home = $1,400
The value of the insurance policy = $5000
The chance that Ted will make a claim on the policy = 10%
The expected value is given as follows
Incidence Probability(p) Value(v) v × p
A claim is made 0.1 $5,000 - $1,400 = -$3,600 -$360
No claim 0.9 $1,400 $1260
Expected value is $1,260 - $360 = $900
The value the insurance company can be expected to make on average on the policy is $900

Aaron can paint a door in 6 h, and Ana can do the same job in 3 h. Working together, how many hours will it take them to paint a door?
h
Answers
Answer:
4.5
Step-by-step explanation:
that is
their rates =1/6, 1/3 respectively
total =1/2
if 1/2=9
1= 9/2
= 4.5
We want to find the rate at which Aaron and Ana work together, we will find that when working together they can paint 1 door in 2 hours.
Working with rates:
We know that Aaron can paint a door in 6 hours and Ana can paint the same door in 3 hours. The rates are just defined as the number of doors painted over time, so we get:
Aaron's rate = (1 door/ 6h)Ana's rate = (1 door/ 3h)When they work together the rates just add up, so we get:
R = (1 door/ 6h) + (1 door/ 3h) = (1 door/ 6h) + (2 door/ 6h)
= (3 doors/6 hours) = (1 door/ 2 hours)
This means that, working together, they can paint 1 door in 2 hours.
