What will the dividend income be on W number of shares of XYZ stock if XYZ distributes a $Y per share dividend?
Answer:
In general, the dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend.
Step-by-step explanation:
The dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend. This is because the dividend income is calculated by multiplying the number of shares that an investor owns by the amount of the dividend per share.
For example, if an investor owns W = 100 shares of XYZ stock and XYZ distributes a $Y = 5 per share dividend, then the investor's dividend income will be 100 * 5 = 500 dollars.
In general, the dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend.

the graph shoes the value a stock( to the nearest dollar) over an 8-hour period. FInd the average rate of change in the stock from hour 3 to hour 7. Round to the nearest cent if necessary.
The average rate of change in the stock from hour 1 to hour 6 is -$0.20/hr.
What is average rate of change in stock?
By subtracting the price of a security at time B from the price of the same security at time A and dividing the result by the price at time A, the price rate of change can be calculated. The indicator is a technical analysis tool that measures unbounded velocity versus a zero-level middle.We need to find the average rate of change of stock from 1 hour to 6 hours.
The value of stock was $11 in hour 1 and $10 in hour 6.
Average rate of change = Δy/ Δx
= $10 - $11 / 6-1
= - $1/5
= -$0.20 /hr
Hence, the average rate of change in the stock from hour 1 to hour 6 is -$0.20/hr.

You have two instruments with which to measure the height of a tower. If the true height is 100 meters, measurements with the first instrument vary with mean 100 meters and standard deviation 1. 2 meters. Measurements with the second instrument vary with mean 100 meters and standard deviation 0. 85 meter. You make one measurement with each instrument. Your results are X1 for the first and X2 for the second, and are independent. A) To combine two measurements, you might average them, Y=(X1+X2)/2. What are the mean and standard deviation of Y? b) It makes sense to give more weight to the less variable measurement because it is more likely to be close to the truth. Statistical Theory says that to make the standard deviation as small as possible you should weight X2 is very close to half the variance of X1, so X2 should get twice the weight of X1. That is, use W=1/3X1 + 2/3X2 What are the mean and standard deviation of W?
(a) The mean of Y is 100 meters, and the standard deviation of W is approximately 0.7348 meters.
(b) The mean of W is 100 meters, and the standard deviation of W is approximately 0.6935 meters.
a) To find the mean and standard deviation of Y, where Y = (X₁ + X₂) / 2, we use the properties of the mean and variance of a sum of independent random variables.
Mean of Y:
The mean of Y is simply the average of the means of X₁ and X₂, as the measurements are independent and have the same true height of 100 meters.
Mean(Y) = (Mean(X₁) + Mean(X₂)) / 2 = (100 + 100) / 2 = 100 meters
The standard deviation of Y:
When adding or subtracting independent random variables, the variances add up. Since the measurements are independent, we can use the formula:
Var(Y) = Var((X₁ + X₂) / 2) = (Var(X₁) + Var(X₂)) / 4
Now, calculate the variance of Y:
Var(Y) = (1.2² + 0.85²) / 4 ≈ 0.54
Standard deviation(Y) = √Var(Y)
≈ √0.54
≈ 0.7348 feet
b) Now, let's find the mean and standard deviation of W, where W = (1/3)X₁ + (2/3)X₂.
Mean of W:
Mean(W) = (1/3) * Mean(X₁) + (2/3) * Mean(X₂)
= (1/3) * 100 + (2/3) * 100
= 100 meters
The standard deviation of W:
To calculate the standard deviation of W, we need to find the variance of W and then take its square root.
Var(W) = (1/3)² * Var(X₁) + (2/3)² * Var(X₂)
= (1/9) * 1.2² + (4/9) * 0.85²
Now, calculate the variance of W:
Var(W) = 0.0181 + 0.1956 =0.481
Standard deviation(W) = √Var(W)
≈ √0.481
≈ 0.6935 meters
So, the mean of W is 100 meters, and the standard deviation of W is approximately 0.6935 meters.

The volume of a cylinder having height one and half of the radius is 12,936 m3 what minimum square cm of paper is needed to cover the curved surface area of the cylinder? The answer should be 1848m2. please solve my question.
Answer:
Lateral Surface Area = 1848 m^2 (does not include the top and bottom)
Step-by-step explanation:
Vol Cylinder = pi*r^2 *h
h = (3/2)r
Vol = pi*r^2((3/2)r) [We are told that the volume is 12,936 m^3]
pi*r^2((3/2)r) = 12,936 m^3
pi*(3/2)*(r^3) = 12,936 m^3
pi*r^3 = (12,936 m^3)*(2/3)
pi*r^3 = 8,624 m
r^3 = (8,624 m)/(3.14)
r^3 = 2745.1
r = 14.0 m
Lateral Surface = 2*(pi)*r*h [Lateral is just the curved portion of the right cylinder.
Lateral Surface Area = 2*(3.14)*(14.0)(21.0)
Lateral Surface Area = 1848 m^2

The number of beads in a jar is 50 to the nearest ten.
(a) What is the minimum possible number of beads in the jar?
(b) What is the maximum possible number of beads in the iar?
Answer:
a) 45
b) 54
Step-by-step explanation:
a) To be able to round up to the nearest 10, the number in the "ones column" needs to be 5 at the minimum.
You could argue it could be a decimal point however, you shouldn't really have a decimal of a bead ( it's possible but it over complicates the answer ) and, it's to the nearest 10, not nearest one decimal point for example.
Therefore, the min is 45 beads
b) ( The above poster was correct oops, I made a silly mistake )
The max is 54 beads as if anything in the ones column is under 4, you can't round up to the nearest 10. Hence it remains as 50 when rounding
Therefore, the max is 54 beads

Answer:

4 = 41
5 = 71
6 = 109
Step-by-step explanation:
This may seem tricky at first, but if you follow the order of the numbers, you can find them fairly quickly using the values already given.
For angle 1:
The angle above it of 45 degrees is similar to angle 1, so that it automatically going to be 45
For angle 2:
The same concept for angle 1 applies for angle 2, so it will be 75 degrees.
For angle 3:
All triangles add up to 180 degrees. So, since we have angles 1, and 2, solve to find 3:
180 - 45 - 75 = 60
For angle 4:
All straight lines add up to 180 degrees. So solve to find angle 4 using the value we found for angle 3:
180 - 60 - 79 = 41
For angle 5:
Angle 5 is part of another triangle and we have two of the angles already. So solve to find angle 5 using the logic used to find angle 3:
180 - 41 - 68 = 71
For angle 6:
angles 5 and 6 are part of a straight line, so use the same logic for angle 4 and solve for angle 6:
180 - 71 = 109
