Answers
Answer:
The first such year is 2002.
Step-by-step explanation:
For them to be the same upside down as right side up, the first and last digit have to be the same.
Since we are in the 21st century, and the years begin with 2, then have to end with 2. So
2xx2.
Numbers that look the same upside down as right side up are: 0,1,2,5,8. So, the first possible year is:

Answer:
y = 3/2x + 1
Step-by-step explanation:
The equation of a line that is perpendicular to the line y-4 = -(x-6) and passes through the point (-2, −2) is y = 3x/2 - 1
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given is an equation of a line y-4 = -(x-6), we need to find the equation of a line that is perpendicular to the line y-4 = -(x-6) and passes through the point (-2, −2),
We know that the slopes of perpendicular lines are negative reciprocal of each other,
Slope intercept form = y = mx + b
m = slope of the line = -2/3
y = -2/3x + b
Plug in (-2, -2) and the perpendicular line is
y = 3/2x - 1
Hence, the equation of a line that is perpendicular to the line y-4 = -(x-6) and passes through the point (-2, −2) is y = 3x/2 - 1

The time spent higher than 26 meters above the ground is 0.42 minutes. Answer: 0.42
A Ferris wheel is 30 meters in diameter and boarded from a platform that is 4 meters above the ground.
The six o'clock position on the Ferris wheel is level with the loading platform.
The wheel completes 1 full revolution in 2 minutes.
We have to find how many minutes of the ride are spent higher than 26 meters above the ground.
So, let's start with some given data,Consider the height of a person at the six o'clock position = 4 meters
So, the height of a person at the highest point = 4 + 15 = 19 meters (since the diameter is 30 meters, the radius will be 15 meters)
Also, the height of a person at the lowest point = 4 - 15 = -11 meters
Therefore, the Ferris wheel completes one cycle from the lowest point to the highest point and back to the lowest point.
So, the total distance travelled will be = 19 + 11 = 30 meters.
Also, we are given that the wheel completes 1 full revolution in 2 minutes.
We need to calculate the time spent higher than 26 meters above the ground.
So, the angle between the 6 o'clock position and 2 o'clock position will be equal to the angle between the 6 o'clock position and the highest point.
This angle can be calculated as follows:
Angle = Distance travelled by the Ferris wheel / Circumference of the Ferris wheel * 360 degrees
Angle = 30 / (pi * 30) * 360 degrees
Angle = 360 degrees / pi
= 114.59 degrees
So, the total angle between the 6 o'clock position and the highest point is 114.59 degrees.
Now, we need to find out how much time is spent at an angle greater than 114.59 degrees.
This can be calculated as follows:
Time = (Angle greater than 114.59 degrees / Total angle of the Ferris wheel) * Total time taken
Time = (180 - 114.59) / 360 * 2 minutes
Time = 0.42 minutes

The bus that is the most consistent, given the data collected on travel times to school from two groups of students is C Bus 18, with a range of 10
How to find the consistent bus ?To determine which bus is the most consistent, we should use the interquartile range (IQR) as the measure of variability. The IQR measures the spread of the middle 50% of the data, which makes it less sensitive to outliers compared to the range.
Bus 47:
Median (Q2): 16
Q1: 10
Q3: 22
IQR = Q3 - Q1 = 22 - 10 = 12
Bus 18:
Median (Q2): 12
Q1: 8
Q3: 18
IQR = Q3 - Q1 = 18 - 8 = 10
Bus 18 has a smaller IQR than Bus 47 (10 vs. 12), which means the travel times for Bus 18 are more consistent.
Note: Figures might be different due to options being for different variant but Bus 18 is the most consistent.

In the past few years, many small businesses have been faced with difficulty keeping their doors open, and in many cases large corporations with cash on hand have come in to take over the companies and their real estate. In such case, a large restaurant chain purchased a small corner tavern with plans to use the name to build a local franchise. The cost of buying the franchise naming rights was four times the cost of buying the physical property. If the total purchase price was $1,250,000, how much did the restaurant chain pay for each individual element of the sale ( naming rights and physical property)?
Answers
The restaurant chain paid $625,000 for the physical property and $2,500,000 for the franchise naming rights, for a total purchase price of $1,250,000.
What is sale?Sale refers to the transfer of ownership of goods or services from one person to another in exchange for money or other consideration.
The total purchase price of the franchise naming rights and physical property was $1,250,000.
To calculate the amount paid for each individual element of the sale, the total purchase price must be divided by the two elements.
The total purchase price of $1,250,000 divided by two elements equals $625,000.
This means that the restaurant chain paid $625,000 for the franchise naming rights and $625,000 for the physical property.
The amount of money paid for the franchise naming rights (four times the cost of buying the physical property) can be calculated by multiplying the cost of the physical property, which is
$625,000/4 .
When the cost of the physical property is multiplied by four, the result is $2,500,000.
This means that the restaurant chain paid $2,500,000 for the franchise naming rights.
In summary, the restaurant chain paid $625,000 for the physical property and $2,500,000 for the franchise naming rights, for a total purchase price of $1,250,000.

Answers
Answer:
75% of all students have GPAs between 1.5 and 3.5
Step-by-step explanation:
11% of all students at this high school have GPA of 3.5 of higher:
This means that a GPA of 3.5 is in the 100 - 11 = 89th percentile, that is, a student that gets a GPA of 3.5 has a higher GPA than 89% of students.
14% have GPAs of 1.5 or lower.
This means that a GPA os 1.5 is in the 14th percentile, that is, a student that gets a GPA of 1.5 has a higher GPA than 14% of students.
What percentage of all students have GPAs between 1.5 and 3.5?

The events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.
What is probability?The probability is defined as the chances of happening any event. Mutually exclusive events are those in which the one event is independent of the other event.
The condition for the mutually exclusive event will be:
\(P(A|B)=\dfrac{P(A) \ and P(B)}{P(A)}=P(A)\)
We have the data
red, 0.28
black, 0.30
white, 0.22
other 0.20
Here we will check the mutually exclusive event:-
(1)The events red and black
\(P(R|B)=\dfrac{P(R\ and\ B)}{P(B)}\)
\(P(R|B)=\dfrac{0.28\times 0.30}{0.30}=0.28 =P(R)\)
Hence the event is exclusive.
(2)The events white and other
\(P(W|O)=\dfrac{P(W\ and\ O)}{P(O)}=P(W)\)
\(P(W|O)=\dfrac{ 0.22\times 0.20}{0.20}=0.22=P(W)\)
Hence the event is exclusive.
(3) The events red and other
\(P(R|O)=\dfrac{P(R\ and\ O)}{P(O)}=P(R)\)
\(P(R|O)=\dfrac{ 0.28\times 0.20}{0.20}=0.28=P(R)\)
Hence the event is exclusive.
Hence the events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.

you're valuing horn of plenty mining, inc.'s, stock in order to compare its value to its market price. you believe that the company will pay total dividends of $1.45 in 2015 and $1.56 in 2016. you also believe the company's stock price will be $35.80 at the end of 2016. if the appropriate discount rate is 12 percent, what's the value of horn of plenty mining's stock? a. $39.22 b. $38.31 c. $36.87 d. $37.43
Answers
Step 1: Calculate the present value of each dividend payment.
PV(2015) = $1.45 / (1 + 0.12)^1 = $1.29
PV(2016) = $1.56 / (1 + 0.12)^2 = $1.22
Step 2: Calculate the present value of the expected stock price at the end of 2016.
PV(2016 stock price) = $35.80 / (1 + 0.12)^2 = $28.33
Step 3: Add up the present values of the dividend payments and stock price to get the total stock value.
Stock value = PV(2015) + PV(2016) + PV(2016 stock price) = $1.29 + $1.22 + $28.33 = $30.84
Therefore, the value of Horn of Plenty Mining's stock is $30.84, which means that the correct option is e) None of the above.

What is the x and y-intercept of 10x 2y 20?; How do you find x intercepts and y intercepts?; How do you find the x and y intercepts of a function?; What is the slope of a line perpendicular to 10x 4y 20?
Answers
The x-intercept = 2 and y-intercept = 10 of the given line 10x + 2y = 20. The slope of the line perpendicular to 10x + 4y = 20 is 2/5.
a. To find the x- and y-intercept of the line 10x + 2y = 20
we will put x=0 to get the y-intercept, which is given by 2y = 20 i.e. y = 10.
similarly, we will put y = 0 to get the x-intercept, which is given by 10x= 20 i.e. x=2.
Hence, we have x-intercept = 2 and y-intercept = 10.
b. To To find the x- and y-intercept of the line.
We will first put x=0 in the given equation of the line to find the y-intercept of the line and then put y=0 in the given equation of the line to find the x-intercept of the line.
c. We have to find the slope of a line perpendicular to 10x + 4y = 20.
let us convert the given line equation in the slope-intercept form i.e. y = mx+ b
hence, 10x + 4y = 20
4y = -10x + 20 -------- ( subtracting 10x on both sides )
y = -10x/4 + 20/4 -------- ( dividing both sides by 4 )
y = -(5/2)x + 5
This is the required slope-intercept form, where -5/2 =m which represents the slope of the line.
The slope of a line perpendicular to the given line is calculated by taking the negative reciprocal of the slope of the given line.
So, the negative reciprocal -5/2 is 2/5.
the negative reciprocal of the slope of the given line will be 2/5.
Hence, the slope of the line perpendicular to 10x + 4y = 20 is 2/5.

The impact on Carns’s income from eliminating the Small Tools Division would be: Multiple Choice
Answers
The impact on Carns Company's income from eliminating the Small Tools Division would be a decrease of $1,209,000.
To determine the impact on Carns Company's income from eliminating the Small Tools Division, we need to consider the avoidable costs associated with the division.
The avoidable costs include all of the variable costs of the division and a portion of the fixed costs that are specifically related to the Small Tools Division. In this case, the variable costs of the division are $1,295,000, and $119,000 of the fixed costs are avoidable.
To calculate the impact on income, we subtract the avoidable costs from the loss reported by the division:
Impact on income = Loss - Avoidable costs
Impact on income = $205,000 - ($1,295,000 + $119,000)
Impact on income = $205,000 - $1,414,000
Impact on income = -$1,209,000
The negative sign indicates a decrease in income.

Step-by-step explanation:

Suppose a discrete random variable X has the following probability mass function
fX(x) = (1 − γ)γx, x = 0, 1, 2, 3...where γ is a fixed parameter and 0 < γ < 1.
Find: (a) the mgf of X; (b) the mean and the variance.
Answers
(a) the mgf of X is M_X(t) = (1 - γ) / (1 - γe^t).
(b) the mean and the variance is E[X] = γ / (1 - γ) and Var(X) = γ / (1 - γ), respectively.
The moment generating function (mgf) of a random variable X is defined as M_X(t) = E[e^(tX)], where t is a real number and E[X] denotes the expected value of X.
To find the mgf of X, we can first calculate the expected value of e^(tX) for each possible value of X:
E[e^(tX)] = (1 - γ)e^(t0) + γe^(t1) + (1 - γ)e^(t2) + γe^(t3) + ...
This infinite series can be simplified using the geometric series formula:
E[e^(tX)] = (1 - γ) + γe^t + (1 - γ)e^(2t) + γe^(3t) + ...
= (1 - γ) / (1 - γe^t)
Thus, the mgf of X is M_X(t) = (1 - γ) / (1 - γe^t).
To find the mean and variance of X, we can use the following formulas:
Mean of X: E[X] = ΣxP(X=x) = ΣxfX(x)
= 0(1 - γ) + 1γ + 2(1 - γ) + 3γ + ...
= γ / (1 - γ)
Variance of X: Var(X) = E[X^2] - (E[X])^2
= Σx^2fX(x) - (E[X])^2
= 0^2(1 - γ) + 1^2γ + 2^2(1 - γ) + 3^2γ + ... - (γ / (1 - γ))^2
= γ / (1 - γ)^2 - (γ / (1 - γ))^2
= γ / (1 - γ)
