Four years ago. Sherman bought 150 shares of Boca-Cola stock for $15 a share. He received a dividend of $0.30 per share each year. If the stock price has increased to $50 per share, what would be his total return?
Answers
Sherman's total return on his investment in Boca-Cola stock is $5,430.
The formula for the total return on an investment is as follows:
total return = capital gain + dividend yield
Initially, Sherman bought 150 shares of Boca-Cola stock for $15 a share.
Therefore, the initial investment (also known as the initial cost) is:
$15 x 150 = $2,250
Four years later, the stock price of Boca-Cola is $50 per share.
The capital gain is calculated as follows:
capital gain = final share price - initial share price
capital gain = $50 - $15
capital gain = $35
Therefore, the capital gain on Sherman's 150 shares is:
$35 x 150 = $5,250
Next, we need to calculate the total amount of dividends that Sherman received over the 4 years. The dividend per share is $0.30. Therefore, the total amount of dividends received is:
total dividends = dividend per share x number of shares x number of years
Sherman received dividends for 4 years, so:
total dividends = $0.30 x 150 x 4
total dividends = $180
The dividend yield is calculated as follows:
dividend yield = total dividends / initial cost
dividend yield = $180 / $2,250
dividend yield = 0.08 or 8%
Finally, we can calculate the total return:
total return = capital gain + dividend yield
total return = $5,250 + $180
total return = $5,430
Therefore, Sherman's total return on his investment in Boca-Cola stock is $5,430.

Using a standard deck of 52 cards, what is the probability that a
randomly dealt 5-card hand contains 2 kings and 3 cards that aren't
kings?
Answers
The probability that a randomly dealt 5-card hand contains 2 kings and 3 cards that aren't
kings is approximately 0.0399 or 3.99%.
To find the probability of randomly dealing a 5-card hand containing 2 kings and 3 cards that aren't kings, we need to calculate the number of favorable outcomes and divide it by the total number of possible outcomes.
The number of ways to choose 2 kings from the 4 available kings is given by the combination formula:
C(4, 2) = 4! / (2! * (4-2)!) = 6
Similarly, the number of ways to choose 3 non-king cards from the remaining 48 cards (52 cards total - 4 kings) is:
C(48, 3) = 48! / (3! * (48-3)!) = 17,296
Therefore, the number of favorable outcomes (hands with 2 kings and 3 non-king cards) is:
6 * 17,296 = 103,776
The total number of possible 5-card hands that can be dealt from a standard deck of 52 cards is:
C(52, 5) = 52! / (5! * (52-5)!) = 2,598,960
So, the probability of randomly dealing a 5-card hand containing 2 kings and 3 cards that aren't kings is:
P(2 kings and 3 non-kings) = favorable outcomes / total outcomes = 103,776 / 2,598,960 ≈ 0.0399
Therefore, the probability is approximately 0.0399 or 3.99%.

The number of cellular phones in use in the United States is increasing exponentially The number, N, in millions, in use is given by the exponential function N(t) -0.05(1.32), where "q" is the number of years after 1990. (Source: Cellular Telecommunications and Internet Association) Find N(30) and explain its meaning in the context of the scenario, b. Find t when N(O) = 420 and explain its meaning in the context of the scenario, c. Explain the meaning of the value 1.32 (from the equation) in the context of the scenario. 4. Use your calculator's graphing feature to solve 3' = 4x+5. Explain how you used your calculator and reproduce any tables or graphs produced by your calculator. Include detailed graph for points too please.
Answers
The number of cellular phones in the US is projected to grow exponentially, reaching 5.071 million in 30 years and 420 million in 13.955 years. The growth factor is 1.32, which suggests that the number of cellular phones is increasing by approximately 32% each year.
a. To find N(30), we substitute t = 30 into the given exponential function:
[tex]\[N(t) = 0.05 * (1.32)^t\][/tex]
N(30) = 0.05 * (1.32)³⁰
You can calculate this value using a calculator or a computer software. The result is approximately 5.071 million.
In the context of the scenario, N(30) represents the estimated number of cellular phones in use in the United States, in millions, 30 years after 1990. It indicates the projected growth in the number of cellular phones over time based on the given exponential function.
b. To find t when N(0) = 420, we set N(t) equal to 420 and solve for t:
[tex]\[420 = 0.05 * (1.32)^t\][/tex]
Dividing both sides by 0.05:
[tex]\begin{equation}8400 = (1.32)^t[/tex]
To solve this equation for t, we can take the logarithm of both sides using the base 1.32:
log(8400) = t * log(1.32)
Now, solve for t by dividing both sides by log(1.32):
[tex]\begin{equation}t = \log(8400) / \log(1.32)[/tex]
You can calculate this value using a calculator or a computer software. The result is approximately 13.955 years.
In the context of the scenario, t represents the number of years after 1990 when the number of cellular phones in use in the United States reaches 420 million. It indicates the time it takes for the number of cellular phones to reach a specific value based on the given exponential function.
c. The value 1.32 in the equation N(t) = 0.05 * (1.32)^t represents the growth factor or the rate of exponential growth of the number of cellular phones. It indicates how much the number of cellular phones is multiplied by each unit of time (in this case, each year). In this scenario, the value 1.32 suggests that the number of cellular phones is increasing by approximately 32% each year.

Use convolution notation with and set up the integral to write the final answer of the following initial value ODE. There is no need to evaluate the integral. x" - 8x' + 12x = f(t) with f(t)
Answers
The integral representation of the solution to the initial value ordinary differential equation (ODE) x'' - 8x' + 12x = f(t) with f(t) is given by x(t) = x₀ * δ(t) + x₁ * δ'(t) + ∫[a,b] G(t - τ) * f(τ) dτ.
The given ODE is a linear homogeneous second-order ODE with constant coefficients. To find the integral representation of the solution, we introduce the Dirac delta function, δ(t), and its derivative, δ'(t), as the basis for the particular solution.
To set up the integral representation for the solution of the initial value ODE x'' - 8x' + 12x = f(t), we first define the Green's function G(t - τ). The Green's function satisfies the homogeneous equation with the right-hand side equal to zero:
G''(t - τ) - 8G'(t - τ) + 12G(t - τ) = 0.
Next, we set up the integral representation as follows:
x(t) = x₀ * δ(t) + x₁ * δ'(t) + ∫[a,b] G(t - τ) * f(τ) dτ,
The integral represents the convolution of the forcing function f(τ) with the Green's function G(t - τ).

Starting a business is a risky, but sometimes very profitable decision. Last year, a financial analyst tracked business startups in the IT industry and found that 65% of these businesses generated a profit in their first year. The analyst decides to track 50 new IT businesses this year. Assuming a binomial distribution, a. What is the probability that exactly 32 of them will generate a profit in the next year? b. What is the probability that at most 30 will generate a profit in the next year? c. What is the probability that at least 35 of them will generate a profit in the next year?
Answers
(a) The probability of success is 65% or 0.65, and the number of trials is 50.
(b) The probability as follows:
P(X ≤ 30) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 30)
(C) The probability as follows:
P(X ≥ 35) = P(X = 35) + P(X = 36) + P(X = 37) + ... + P(X = 50)
a. The probability of exactly 32 of the 50 IT businesses generating a profit in the next year can be calculated using the binomial distribution formula. In this case, the probability of success (a business generating a profit) is 65% or 0.65, and the number of trials is 50. Using the formula, we can calculate the probability as follows:
P(X = 32) = C(50, 32) * (0.65)^32 * (1 - 0.65)^(50 - 32)
where C(n, k) represents the binomial coefficient, equal to n! / (k! * (n - k)!). Calculating this expression gives us the probability that exactly 32 businesses will generate a profit.
b. To calculate the probability that at most 30 businesses will generate a profit, we need to find the cumulative probability from 0 to 30. We can calculate the probability as follows:
P(X ≤ 30) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 30)
The problem involves determining the probability that at most 30 out of 50 IT businesses will generate a profit in their first year. We can use the binomial distribution formula to calculate this probability. The formula is given by:
P(X ≤ k) = Σ (nCk * p^k * q^(n-k))
Where:
P(X ≤ k) is the probability of having at most k successes,
n is the number of trials (50 businesses),
k is the number of successes (profitable businesses),
p is the probability of success (65% or 0.65),
q is the probability of failure (35% or 0.35),
nCk is the combination formula (n choose k).
To find the probability that at most 30 businesses will generate a profit, we need to calculate the cumulative probability from 0 to 30. Using the binomial distribution formula, we can find the probability of each possible outcome (0, 1, 2, ..., 30) and sum them up. The cumulative probability can be calculated using software or statistical tables.
c. To calculate the probability that at least 35 businesses will generate a profit, we need to find the cumulative probability from 35 to 50. We can calculate the probability as follows:
P(X ≥ 35) = P(X = 35) + P(X = 36) + P(X = 37) + ... + P(X = 50)
These calculations can be performed using a statistical software package, spreadsheet software, or using statistical tables for the binomial distribution.

A simple random sample of size n = 49 is obtained from a population that is skewed right with µ = 81 and σ = 14. (a) Describe the sampling distribution of x. (b) What is P (x>84.9)? (c) What is P (x≤76.7)? (d) What is P (78.1
Answers
The sampling distribution of x is N (µx = µ = 81, σx = 2.00).The probability of x > 84.9 is:P(x > 84.9) = P(z > 1.75) = 0.0401.The probability of 78.1 < x < 81 is:P(78.1 < x < 81) = P(-0.95 < z < 0) = 0.3289.
a)Sampling distribution of x
The sampling distribution of x is the probability distribution of all the possible sample means that can be drawn from a population under the same sampling method.
It represents the relative frequency of different values of x (sample mean) that can be obtained when samples of size n are taken from the population.
The sampling distribution of x is approximately normal when the sample size is sufficiently large, i.e. n ≥ 30. In this case, n = 49, which is sufficiently large to assume normality of sampling distribution of x.
The mean of the sampling distribution of x is µx = µ = 81, and the standard deviation is: σx = σ / √n = 14 / √49 = 2.00.
Hence, the sampling distribution of x is N (µx = µ = 81, σx = 2.00).
b)P(x > 84.9)
The z-score is:z = (x - µx) / σx = (84.9 - 81) / 2.00 = 1.75.
Using the standard normal distribution table, the probability of z > 1.75 is 0.0401.
Hence, the probability of x > 84.9 is:P(x > 84.9) = P(z > 1.75) = 0.0401
c)P(x ≤ 76.7)
The z-score is:z = (x - µx) / σx = (76.7 - 81) / 2.00 = -2.15
Using the standard normal distribution table, the probability of z ≤ -2.15 is 0.0150.
Hence, the probability of x ≤ 76.7 is:P(x ≤ 76.7) = P(z ≤ -2.15) = 0.0150d)P(78.1 < x < 81)
The z-score for x = 78.1 is:z1 = (x1 - µx) / σx = (78.1 - 81) / 2.00 = -0.95
The z-score for x = 81 is:z2 = (x2 - µx) / σx = (81 - 81) / 2.00 = 0
Using the standard normal distribution table, the probability of z1 < z < z2 is:P(z1 < z < z2) = P(-0.95 < z < 0) = P(z < 0) - P(z < -0.95) = 0.5000 - 0.1711 = 0.3289.
Hence, the probability of 78.1 < x < 81 is:P(78.1 < x < 81) = P(-0.95 < z < 0) = 0.3289.

Answers
In Exhibit 34-1, the opportunity cost of one unit of Y in Country B is 2 units of X.
Opportunity cost refers to the value of the next best alternative that is forgone when making a choice. In this case, the opportunity cost of one unit of Y in Country B is being compared to the amount of X that could be produced instead.
The given information states that the opportunity cost of one unit of Y in Country B is 2 units of X. This means that for every unit of Y that Country B produces, it must give up the production of 2 units of X. In other words, the resources and efforts that could have been used to produce 2 units of X are instead allocated to producing one unit of Y.
This relationship indicates the relative trade-off between the production of X and Y in Country B. By sacrificing the production of 2 units of X, Country B can produce one unit of Y. The opportunity cost of producing Y is therefore 2 units of X.

Answers
The equation of the sphere in standard form, one of whose diameters have (-5, 2, 9) and (3, 6, 1) as endpoints, is [tex]x^2 + y^2 + z^2 - 8x - 4y - 10z + 48 = 0[/tex]. Therefore, the correct option is (d) [tex]x^2 + y^2 + 7 + 2x + 8y - 10z - 6 = 0[/tex].
To find the equation, we start by finding the center of the sphere. The center of the sphere is the midpoint of the line segment connecting the given endpoints. Using the midpoint formula, we find the center to be [tex]((-5 + 3)/2,(2 + 6)/2,(9 + 1)/2) = (-1, 4, 5)[/tex].
Next, we find the radius of the sphere. The radius is half the length of the diameter, which is the distance between the two endpoints. Using the distance formula, we find the radius to be [tex]\sqrt{(-5 - 3)^2 + (2 - 6)^2 + (9 - 1)^2} = \sqrt{64 + 16 + 64} = \sqrt{144} = 12[/tex].
Finally, we substitute the center and radius into the equation of a sphere: [tex](x - h)^2 + (y - k)^2 + (z - l)^2 = r^2[/tex], where (h, k, l) is the center and r is the radius. Plugging in the values, we get [tex](x + 1)^2 + (y - 4)^2 + (z - 5)^2 = 12^2[/tex].
Expanding and simplifying, we arrive at the equation for sphere's standard form, [tex]x^2 + y^2 + z^2 - 8x - 4y - 10z + 48 = 0[/tex].
Therefore, the correct option is (d) [tex]x^2 + y^2 + 7 + 2x + 8y - 10z - 6 = 0[/tex].

The volume of a triangular prism with a base 8 cm and height of 4 cm, length of 20 cm = 0.32 liters.
To calculate the volume of a triangular prism, you multiply the area of the base triangle by the length of the prism. Given that the base triangle has a side length of 8 cm and a height of 4 cm, its area can be calculated as (1/2) * base * height = (1/2) * 8 cm * 4 cm = 16 cm².
Multiplying this by the length of the prism, which is 20 cm, we get the volume:
Volume = Base Area * Length = 16 cm² * 20 cm = 320 cm³.
To convert this volume to liters, we know that 1 liter is equal to 1000 cm³. Therefore, we can divide the volume in cm³ by 1000 to obtain the volume in liters:
Volume in liters = 320 cm³ / 1000 = 0.32 liters.
So, the volume of the triangular prism is 0.32 liters.
