Philip owns 100 shares of a stock that is trading at $97. 55 and pays an annual dividend of $2. 74. How much should he receive in quarterly dividends? What's the annual yield on this stock?
Philip should receive $68.50 in quarterly dividends and the annual yield on this stock is about 2.81%.
To calculate the quarterly dividend that Philip need to acquire, we need to first calculate the quarterly dividend per share:
Quarterly dividend in step with share = Annual dividend per percentage / 4
In this situation, the once a year dividend in line with proportion is $2.74, so the quarterly dividend per proportion is:
Quarterly dividend per proportion = $2.74 / 4 = $0.685
For the reason that Philip owns 100 shares, his quarterly dividend should be:
Quarterly dividend = Quarterly dividend per share * number of stocks
Quarterly dividend = $0.685 * 100 = $68.50
Therefore, Philip should receive $68.50 in quarterly dividends.
To calculate the once a year yield on this inventory, we want to divide the yearly dividend in line with proportion by the present day stock price, after which multiply by way of 100 to specific the result as a percentage:
Annual yield = (Annual dividend per share / inventory price) * 100
In this case, the annual dividend per percentage is $2.74, and the inventory charge is $97.55. Plugging those values into the components, we get:
Annual yield = ($2.74 / $97.55) * 100
Annual yield ≈ 2.81%
Therefore, the annual yield on this stock is about 2.81%.

the weekly sales at two movie theaters were recorded for a random sample of 25 weeks. a 95 percent confidence interval for the difference in mean weekly sales for the two movie theaters was calculated as
To calculate the 95% confidence interval for the difference in mean weekly sales for the two movie theaters, follow these steps:
Step 1: Gather the data for the random sample of 25 weeks.
Step 2: Calculate the mean and standard deviation for each movie theater's weekly sales.
Step 3: Calculate the difference in mean weekly sales for the two movie theaters (subtract the mean of theater 2 from the mean of theater 1).
Step 4: Calculate the standard error of the difference by taking the square root of [(standard deviation of theater 1^2 / number of weeks) + (standard deviation of theater 2^2 / number of weeks)].
Step 5: Determine the critical value for a 95% confidence interval using a t-table or calculator (for a two-tailed test with 24 degrees of freedom, the critical value is approximately 2.064).
Step 6: Multiply the critical value by the standard error to get the margin of error.
Step 7: Calculate the lower and upper bounds of the confidence interval by subtracting and adding the margin of error from the difference in mean weekly sales.

The position value, r(t) is equals to the (t³/6)k + 2j and velocity value, v(t) is equals to ( t²/2 )k + 4i , for a(t) = tk, v(0) = 4i, r(0) = 2j.
Acceleration is defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quanty.
a = dv/dt
We have the following informations are available,
Initial velocity, v(0) = 4i
Initial position, r(0) = 2j
Acceleration at any time "t",
a(t) = tk
we have to determine the value of v(t) and r(t).
As we know, a(t) = dv(t)/dt = tk
integrating the above equation ,
v(t) = ∫tk dt = ( t²/2 )k + c
at t = 0 , v(0) = 0 + c = 4i ( since, v(0) = 4i
=> c = 4i
So, v(t) = ( t²/2 )k + 4i
Also, velocity is calculated by derivative of postion (r) with respect to time.
=> v(t) = dr(t) /dt
=> r(t) = ∫ v(t) dt
=> r(t) = ∫ ( t²/2 )k dt
integrating value of the right hand side,
r(t) = ( t³/2×3 )k +d
= (t³/6)k + d
At t = 0, r(0) = (0/6)k + d
=> r(0) = d = 2j
so, r(t) = (t³/6)k + 2j
Hence, the required position and velocity are
(t³/6)k + 2j and ( t²/2 )k + 4i.

In a certain sock drawer, there are 4 pairs of black socks, 3 pairs of gray socks and 2 pairs of orange socks. If socks are removed at random without replacement, what is the minimum number of socks that must be removed in order to ensure that two socks of the same color have been removed
Answer:
4 socks.
Step-by-step explanation:
There are three different colors of socks in the drawer: black, gray and orange.
The worst possible scenario for making a pair would be getting a different color of sock with the first three picks (1 black, 1 gray, 1 orange). Since we now have one of each, the next sock drawn from the drawer will form a pair with one of our three socks. Therefore, the minimum number of socks that must be removed in order to ensure that two socks of the same color have been removed is 4.
how many solutions can be found for the equation −4x − 11 = 2(x − 3x) 13? none one two infinitely many
Answer:
One x = 11/48
Step-by-step explanation:
Solve for x:
-4 x - 11 = 2×13 (x - 3 x)
x - 3 x = -2 x:
-4 x - 11 = 2×13×-2 x
2 (-2) = -4:
-4 x - 11 = -4×13 x
-4×13 = -52:
-4 x - 11 = -52 x
Add 52 x to both sides:
52 x - 4 x - 11 = 52 x - 52 x
52 x - 52 x = 0:
52 x - 4 x - 11 = 0
Grouping like terms, 52 x - 4 x - 11 = (-4 x + 52 x) - 11:
((-4 x + 52 x) - 11) = 0
52 x - 4 x = 48 x:
48 x - 11 = 0
Add 11 to both sides:
48 x + (11 - 11) = 11
11 - 11 = 0:
48 x = 11
Divide both sides of 48 x = 11 by 48:
(48 x)/48 = 11/48
48/48 = 1:

What is monomial representations and symmetric presentations?
Answer: A monomial representation is a way to express a polynomial as a product of powers of its variables, where each power is a non-negative integer. For example, the polynomial 2x^3 + 4x^2 - 6x + 8 can be represented as a monomial representation of (2x^3)(x^2)(-6x)(8).
Symmetric polynomials are polynomials that are invariant under permutation of their variables. A symmetric presentation is a way of expressing a symmetric polynomial as a sum of elementary symmetric polynomials, which are defined as the sum of all possible products of variables taken i at a time, where i ranges from 1 to the number of variables. For example, the symmetric polynomial x^3 + y^3 + z^3 can be expressed as a symmetric presentation of x + y + z.

Give your answer to three decimal places. Margin of Error = _____% b) How many randomly sampled residents do we need to survey if we want the 95% margin of error to be less than 3%? Sample size > _____ People
To find the required sample size for a margin of error less than 3%, we can rearrange the formula for the margin of error:
\(n = (Z^2 * p * (1 - p)) / (E^2)\)
Here, Z represents the critical value, p is the estimated proportion (0.51), and E is the desired margin of error (0.03)
To determine the margin of error for the 95% confidence interval, we need to use the formula:
Margin of Error = Critical value * Standard error
The critical value for a 95% confidence level can be obtained from the standard normal distribution table, which corresponds to 1.96. The standard error can be calculated using the following formula:
Standard error = \(\sqrt{(p * (1 - p) / n)}\)
Given that the proportion of North Carolina residents planning to set off fireworks is estimated to be 51% (0.51) based on the survey, we can substitute the values into the formula. However, the sample size (n) is not provided in the question, so we need to determine it in the next part.

Find the equation of clean pulsations for a
left-mounted beam (for x=0) and simple pressed on the right (for
x=l) Take into account that: (sinx)^2+(cosx)^2=1
(chx)^2-(shx)^2=1
We can conclude that there are no nontrivial clean pulsations for the given left-mounted beam with a simple support on the right.
To find the equation of clean pulsations for a left-mounted beam with a simple support on the right, we can use the differential equation that describes the deflection of the beam. Assuming the beam is subject to a distributed load and has certain boundary conditions, the equation governing the deflection can be written as:
d^2y/dx^2 + (chx)^2 * y = 0
Where:
y(x) is the deflection of the beam at position x,
d^2y/dx^2 is the second derivative of y with respect to x,
ch(x) is the hyperbolic cosine function.
To solve this differential equation, we can assume a solution in the form of y(x) = A * cosh(kx) + B * sinh(kx), where A and B are constants, and k is a constant to be determined.
Substituting this assumed solution into the differential equation, we get:
k^2 * (A * cosh(kx) + B * sinh(kx)) + (chx)^2 * (A * cosh(kx) + B * sinh(kx)) = 0
Simplifying the equation and applying the given identity (chx)^2 - (shx)^2 = 1, we have:
(A + A * chx^2) * cosh(kx) + (B + B * chx^2) * sinh(kx) = 0
For this equation to hold for all values of x, the coefficients of cosh(kx) and sinh(kx) must be zero. Therefore, we get the following equations:
A + A * chx^2 = 0
B + B * chx^2 = 0
Simplifying these equations, we have:
A * (1 + chx^2) = 0
B * (1 + chx^2) = 0
Since we are looking for nontrivial solutions (A and B not equal to zero), the expressions in parentheses must be zero:
1 + chx^2 = 0
Using the identity (sinx)^2 + (cosx)^2 = 1, we can rewrite this equation as:
1 + (1 - (sinx)^2) = 0
Simplifying further, we get:
2 - (sinx)^2 = 0
Solving for (sinx)^2, we find:
(sin x)^2 = 2
Since the square of the sine function cannot be negative, there are no real solutions to this equation. Therefore, we can conclude that there are no nontrivial clean pulsations for the given left-mounted beam with a simple support on the right.
