The retail selling price of the keyboard is $43.75.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
To find the retail selling price of the keyboard, we need to add the markup to the cost of the keyboard.
The markup of 150% means that the retailer is adding 150% of the cost to the selling price.
To calculate this, we can first find the dollar amount of the markup:
Markup = 150% of $25
Markup = 0.5 * 150 * $25
Markup = $18.75
This means that the retailer is adding $18.75 to the cost of the keyboard to get the selling price. To find the selling price, we can add the markup to the cost:
Selling price = Cost + Markup
Selling price = $25 + $18.75
Selling price = $43.75
Therefore, the retail selling price of the keyboard is $43.75.

Find the value of x, y, and z in the rhombus below.
The value of x, y, and z in the rhombus below x = 20, y = -7, z = -11
How to find the values of x, y and z?Recall that a rhombus is an equilateral parallelogram with both pairs of opposite sides parallel and all sides the same length.
Sum of interior angles of a rhombus = 360°
The opposite angles of a rhombus are equal to each other.
The adjacent angles are supplementary (add up to 180°)
Therefore,
66 + (6x - 6) = 180
⇒ 66 + 6x - 6 = 180
⇒ 6x = 180 - 66 + 6
⇒ 6x = 120
⇒ x = 120 ÷ 6
⇒ x = 20
66 + (-10z + 4) = 180
⇒ 66 - 10z + 4 = 180
⇒ -10z= 180 - 66 - 4
⇒ -10z = 110
⇒ z = 110 ÷ -10
⇒ z = -11
(6x - 6) + (-10y - 4) = 180
⇒ 6x - 6 - 10y - 4 = 180
⇒ 120 - 6 - 10y - 4 = 180
⇒ -10y = 180 - 120 + 6 + 4
⇒ -10y = 70
⇒ y = 70 ÷ -10
⇒ y = -7

What is the different in the texting rate of these two students?
what is student A's rate ?
Student B's rate ?
what is
Answer:
To compare the texting rates of Student A and Student B, we need to calculate their respective rates of change.
For Student A, we can use the formula for the slope of a line:
slope = (change in y) / (change in x)
In this case, the "y" variable represents the number of texts sent, and the "x" variable represents the number of tests sent. Looking at the table, we can see that Student A sent 10.5 texts after sending 1 test, and 10 texts after sending 2 tests. So the change in y is -0.5 (10.5 - 10), and the change in x is 1. Therefore:
slope = (-0.5) / 1 = -0.5
So Student A's texting rate is -0.5 texts per test.
For Student B, we can look at the graph and find the slope of the line connecting any two points. Let's choose the points (2, 15) and (5, 23) because they are easy to read off the graph. The change in y is 8 (23 - 15), and the change in x is 3 (5 - 2). Therefore:
slope = 8 / 3 = 2.67
So Student B's texting rate is 2.67 texts per minute.
To find the difference in their texting rates, we simply subtract:
difference = Student B's rate - Student A's rate
difference = 2.67 - (-0.5) = 3.17
So the difference in their texting rates is 3.17 texts per test.

How many possible winning number combinations a bettor may opt to select in a 6/42 Lottery? And based on this, what is the probability a bettor may win the lottery jackpot prize?
There are 5,245,786 possible winning number combinations in a 6/42 lottery, and for every ticket purchased, there is a 1 in 5,245,786 chance of winning the jackpot prize.
What is the combinations?
Combinations refer to the different ways of selecting a subset of items from a larger set without regard to the order in which the items are selected. In other words, combinations are the different ways of choosing a group of items without taking into account their arrangement or order.
In a 6/42 lottery, there are 6 numbers drawn from a pool of 42 numbers. To determine the number of possible winning number combinations, we can use the formula for combinations:
C(n,r) = n! / (r! * (n-r)!)
where n is the total number of items in the set and r is the number of items being chosen.
In this case, we have 42 numbers in the pool and we need to choose 6 numbers, so the formula becomes:
C(42,6) = 42! / (6! * (42-6)!)
which simplifies to:
C(42,6) = 5,245,786
Therefore, there are 5,245,786 possible winning number combinations in a 6/42 lottery.
To calculate the probability of winning the jackpot prize, we need to divide the number of ways to win by the total number of possible outcomes. Since there is only one winning combination, the probability of winning the jackpot is:
1 / 5,245,786
which simplifies to approximately:
0.000019% or 1 in 5,245,786.
This means that for every ticket purchased, there is a 1 in 5,245,786 chance of winning the jackpot prize.
hence, there are 5,245,786 possible winning number combinations in a 6/42 lottery, and for every ticket purchased, there is a 1 in 5,245,786 chance of winning the jackpot prize.

Exercise 6.2.8: Solve ′′′ + = 3( − 1) for initial conditions (0) = 1 and ′(0) = 0, ′′(0) = 0.
Answer:
Step-by-step explanation:
To solve the differential equation:
y′′′ + y = 3(y′ − 1)
we first find the characteristic equation:
r^3 + 1 = 0
The roots of this equation are:
r = -1, 0 ± i
So, the general solution of the homogeneous equation (y′′′ + y = 0) is:
y_h(t) = c1 e^(-t) + c2 cos(t) + c3 sin(t)
To find a particular solution of the non-homogeneous equation (3(y′ − 1)), we assume a solution of the form:
y_p(t) = a t + b
Taking the first, second and third derivatives of y_p(t), we get:
y′_p(t) = a
y′′_p(t) = 0
y′′′_p(t) = 0
Substituting these into the differential equation, we get:
0 + (a t + b) = 3(a - 1)
Solving for a and b, we get:
a = 1
b = 2
Therefore, the particular solution of the non-homogeneous equation is:
y_p(t) = t + 2
So, the general solution of the non-homogeneous equation is:
y(t) = y_h(t) + y_p(t) = c1 e^(-t) + c2 cos(t) + c3 sin(t) + t + 2
To find the values of c1, c2 and c3, we use the initial conditions:
y(0) = c1 + c2 + 2 = 1
y′(0) = -c1 + c2 + c3 = 0
y′′(0) = c1 - c2 = 0
Solving these equations simultaneously, we get:
c1 = c2 = 1/2
c3 = -1/2
So, the solution of the differential equation with initial conditions (0) = 1, ′(0) = 0, ′′(0) = 0 is:
y(t) = 1/2 e^(-t) + 1/2 cos(t) - 1/2 sin(t) + t + 2

The second option is to issue new preferred stock at a market price of $56,000, with a $5.00 annual dividend. The net proceeds per share after paying flotation costs are $51.50.
The cost of capital for the second option, issuing new preferred stock, is 0.00356, or 0.356%. This means that for every dollar of capital raised through issuing preferred stock, the company will need to pay 0.356 cents in annual interest or dividend payments.
To calculate the cost of capital for the second option, we need to first calculate the cost of the preferred stock. The cost of preferred stock is the dividend yield, or the annual dividend divided by the market price of the stock. In this case, the annual dividend is $5.00 and the market price is $56,000.
Cost of preferred stock = Annual dividend / Market price of stock
Cost of preferred stock = $5.00 / $56,000
Cost of preferred stock = 0.000089
To calculate the cost of capital, we need to weight the cost of preferred stock with the proportion of capital that is financed by preferred stock. Let's assume that the preferred stock will finance 40% of the total capital.
Cost of capital = Cost of preferred stock * Proportion of capital financed by preferred stock
Cost of capital = 0.000089 * 0.40
Cost of capital = 0.0000356

a mean of 589 grams with standard deviation of 16 grams . if you pick 23 fruits at random then 14% of the time their mean weight will be greater than how many grams?
14% of the time the mean weight of 23 fruits will be greater than approximately 594.33 grams.
What is the Central Limit Theorem (CLT)?
According to the CLT, the distribution of sample means from a population with mean μ and standard deviation σ, will be approximately normal with mean μ and standard deviation σ/√n, where n is the sample size.
In this case, the population mean is 589 grams and the population standard deviation is 16 grams. We are picking a sample of 23 fruits at random, so the standard deviation of the sample means will be:
σ/√n = 16/√23 ≈ 3.33
To find the value of x such that 14% of the time the sample mean will be greater than x, we need to find the z-score that corresponds to the 86th percentile of the standard normal distribution. We can use a table or a calculator to find that z-score:
z = invNorm(0.86) ≈ 1.08
The sample mean is normally distributed with a mean of 589 grams and a standard deviation of 3.33 grams. Using the formula for z-score:
z = (x - μ) / (σ / √n)
We can solve for x:
x = z × (σ / √n) + μ
x = 1.08 × (16 / √23) + 589
x ≈ 594.33 grams
Therefore, 14% of the time the mean weight of 23 fruits will be greater than approximately 594.33 grams.

The height of the Zeta Tower as a percentage of the height of the Delta tower is the 94.72%
How to find the the height of the Zeta Tower as a percentage of the height of the Delta tower?Here we know that:
height of the Delta tower = 55mThe epsilon tower is 23% taller than the delta one, then the height is:
H = 55m*(1 + 0.23) = 67.65 m
And we know that the Zeta tower is 23 short than the epsilon one, then the height of this twoer is.
H' = 67.65m*(1 - 0.23) = 52.0905 m
The height of the delta tower is 55m, this is our 100%.
Then the height of the zeta tower written as a percentage will be:
(52.0905 m/55m)*100% = 94.72%
