You bought 100 shares of stock at $15 per share. You sold your 100 shares at $21. 75 per share. Calculate your percentage of gain.
The percentage gain is 45%
To calculate the percentage gain on your investment, you need to find the difference between the selling price and the buying price, divide that difference by the buying price, and then multiply by 100 to get the percentage.
The difference between the selling price and the buying price is:
$21.75 - $15 = $ 6.75
So the gain on the investment is $ 6.75 per share.
To find the percentage gain, you divide the gain by the buying price:
$6.75 ÷ $15 = 0.45
Then, multiply by 100 to convert this into a percentage :
0.45 x 100% = 45%

Point W is the midpoint of Segment TY. Find the coordinates of Point Y
The coordinates of point Y are (10 - x1, 4y1 - 10), where (x1, y1) are the coordinates of point T.
If W is the midpoint of segment TY, then the coordinates of W are the average of the coordinates of T and Y. Using the midpoint formula, we can find the coordinates of Y:
Let the coordinates of T be (x1, y1) and the coordinates of Y be (x2, y2).
x-coordinate of W = (x-coordinate of T + x-coordinate of Y) / 2
y-coordinate of W = (y-coordinate of T + y-coordinate of Y) / 2
Putting in the coordinates of W and T, we get: 5 = (x1 + x2) / 2
y-coordinate of Y = 2y1 - y-coordinate of W
y-coordinate of Y = 2y1 - (y1 + y2) / 2
Simplifying these equations, we get:
x1 + x2 = 10
y2 = 4y1 - 10
From the first equation, we can solve for x2: x2 = 10 - x1
Putting this into the second equation, we get: y2 = 4y1 - 10

How much would you have to deposit now to be able to withdraw $650 at the end year for 20 years from an account that earns 11% compounded annually?
Please solve this step by step
You would need to deposit approximately $47.83 now to be able to withdraw $650 at the end of each year for 20 years, assuming an annual interest rate of 11% compounded annually.
Describe Interest rate?It is typically expressed as an annual percentage rate (APR). Interest rates can be fixed, meaning they remain the same for the entire term of the loan, or variable, meaning they can change over time based on market conditions or other factors. The interest rate is an important factor to consider when borrowing money, as it affects the overall cost of the loan. It is also a key factor in investment decisions, as it determines the return on an investment.
To calculate the present value of an investment that will yield a future value of $650 for 20 years at 11% annual interest, we can use the formula for present value of an annuity:
PV = FV / (1 + r)ⁿ
where PV is the present value, FV is the future value, r is the interest rate per period, and n is the number of periods.
In this case, we want to find the present value of a 20-year annuity that pays $650 at the end of each year, with an annual interest rate of 11%. Plugging in the values, we get:
PV = $650 / (1 + 0.11)²⁰
PV = $650 / 13.584
PV = $47.83 (rounded to the nearest cent)
Therefore, you would need to deposit approximately $47.83 now to be able to withdraw $650 at the end of each year for 20 years, assuming an annual interest rate of 11% compounded annually.

Suppose John has a torn tendon and is facing surgery to repair it. The surgeon explains the risks to John; infection occurs in 3% of operations, the repair fails in 14% of operations, and both infection AND failure occur together in 0. 57% of operations. What percentage, P, of these operations succeed and are free from infection?
Round to the nearest two decimal places
P = 83.57% after rounding to the closest two decimal places.
As a result, roughly 83.57% of these procedures are successful and infection-free.
We must deduct the percentage of operations that fail, are infected, or both from 100% in order to get the proportion of operations that are successful and free of infection.
Let P represent the proportion of procedures that are both successful and infection-free.
We are aware that 14% of surgeries fail due to repair failure, and 3% of operations result in infection. Hence, 3% + 14% - 0.57% = 16.43% of surgeries have either an infection or a failure, or both.
Hence, 100% - 16.43% = 83.57% is the proportion of surgeries that are successful and free of infection.
P = 83.57% after rounding to the closest two decimal places.
As a result, roughly 83.57% of these procedures are successful and infection-free.

I disagree with Brian's assertion that there is less fluctuation in the number of mystery novels simply because the mean number of mystery books is fewer than the mean number of adventure books.
The mean is merely one measure of central tendency and provides no information about the data's dispersion or variability. We would need to look at a measure of dispersion such as the range, variance, or standard deviation to see whether there is less variety in the quantity of mystery novels. If the range or standard deviation of the number of mystery books is less than that of adventure novels, we may claim that the number of mystery books is less variable. If, however, the If the range or standard deviation of the number of mystery novels is greater than that of adventure books, Brian's statement is false.

Answer:
To show how x² + 6x + 5 is equivalent to (x + 5)(x + 1), we can use the FOIL method, which stands for First, Outer, Inner, and Last.
First, we multiply the first term of each factor: x and x, which gives x².
Next, we multiply the outer terms of each factor: x and 1, which gives x.
Then, we multiply the inner terms of each factor: 5 and x, which gives 5x.
Finally, we multiply the last term of each factor: 5 and 1, which gives 5.
Adding up these terms, we get:
x² + x + 5x + 5
Simplifying by combining like terms, we get:
x² + 6x + 5
This is the same as the original expression. Therefore, we have shown that:
x² + 6x + 5 = (x + 5)(x + 1)

Create a rational expression that simplifies to 2x/(x+1)
and that has the following restrictions on x:
x ≠ −1, 0, 2, 3. Write your expression here.
Answer:
One possible rational expression that simplifies to 2x/(x+1) and meets the given restrictions is:
(4x^2 - 2x - 3) / [(x + 1)(x - 3)(x - 2)]
To see why this expression simplifies to 2x/(x+1), we can simplify the numerator and denominator separately:
Numerator:
2x(2x-1) = 4x^2 - 2x
Denominator:
(x+1)(x-3)(x-2)
Multiplying the numerator and denominator by -1 gives:
(-2x)(2x-1) / [(3-x)(2-x)(1+x)]
Then, we can rearrange the factors in the denominator to get:
(-2x)(2x-1) / [(x+1)(x-2)(x-3)]
Now we have the desired rational expression that simplifies to 2x/(x+1) and has the given restrictions on x.

b) How cool are the coldest 10% of the days (days with lowest average high temperature) during June in LA? Round your answer to 1 decimal place.
The probability of observing an 84°F temperature or higher in LA during a randomly chosen day in June is 0.1151 and the temperature of the coldest 10% of the days (days with lowest average high temperature) during June in LA is approximately 71.6°F.
Let X be the random variable that represents the average daily high temperature in LA in June. Then X ~ N(μ = 78, σ = 5). The probability of observing an 84°F temperature or higher in LA during a randomly chosen day in June is given by: P(X > 84) = P(Z > (84 - 78) / 5) = P(Z > 1.2) = 0.1151 (rounded to 4 decimal places)
To find the temperature of the coldest 10% of the days (days with lowest average high temperature) during June in LA, we need to find the 10th percentile of the distribution. Using a z-score table, we can find the z-score corresponding to the 10th percentile: z = -1.28. Thus, the temperature of the coldest 10% of the days during June in LA is given by: x = μ + zσ= 78 + (-1.28)(5)≈ 71.6°F (rounded to 1 decimal place)

What is Integration ?
In calculus, integration is the inverse operation of differentiation. It is a mathematical technique used to find the integral of a function. The integral of a function f(x) is another function F(x), which gives the area under the curve of f(x) from a certain point to another.
To perform the integration of the given function:
∫(2x-1)÷([tex]x^{2}[/tex]-x-6)dx
First, we need to factor the denominator:
[tex]x^{2}[/tex]- x - 6 = (x-3)(x+2)
So we can rewrite the integral as:
∫(2x-1)÷[(x-3)(x+2)]dx
Next, we need to decompose the fraction into partial fractions:
(2x-1)÷[(x-3)(x+2)] = A÷(x-3) + B÷(x+2)
Multiplying both sides by (x-3)(x+2), we get:
2x-1 = A(x+2) + B(x-3)
Substituting x=3, we get:
5A = 5
A = 1
Substituting x=-2, we get:
-5B = -5
B = 1
So we have:
(2x-1)÷[(x-3)(x+2)] = 1÷(x-3) + 1÷(x+2)
Substituting this back into the integral, we get:
∫(2x-1)÷[(x-3)(x+2)]dx = ∫[1÷(x-3) + 1÷(x+2)]dx
Using the first rule of integration, we get:
∫[1÷(x-3) + 1÷(x+2)]dx = ln|x-3| + ln|x+2| + C
where C is the constant of integration.
Therefore, the final answer is: ∫(2x-1)/[(x-3)(x+2)]dx = ln|x-3| + ln|x+2| + C

[tex] = \displaystyle \int \rm \: \dfrac{2x - 1}{ x(x - 3) + 2(x - 3) } dx[/tex]
[tex] = \displaystyle \int \rm \: \dfrac{2x - 1}{ (x + 2) (x - 3)} dx[/tex]
[tex] \rm \: Let : \displaystyle \rm \: \dfrac{2x - 1}{ (x + 2) (x - 3) } = \dfrac{A }{x + 2} + \dfrac{B}{x - 3} [/tex]
[tex]\rm\implies\displaystyle \rm \: \dfrac{2x - 1}{ (x + 2) (x - 3) } = \dfrac{A(x - 3) + B(x + 2) }{(x + 2)(x - 3)} \\ [/tex]
[tex] \rm \implies\displaystyle \rm \: {2x - 1}{ } = {A(x - 3) + B(x + 2) } \\ [/tex]
Put x = 3 , we get
[tex] \rm \implies\displaystyle \rm \: {6 - 1}{ } = {A(3- 3) + B(3 + 2) } \\ [/tex]
[tex] \rm \implies\displaystyle \rm \: {5}{ } = 5 B \\ [/tex]
[tex] \implies \rm \: B = 1[/tex]
Again
put put x = -2
[tex] \rm \implies\displaystyle \rm \: { - 4- 1}{ } = {A( - 2- 3) + B( - 2 + 2) } \\ [/tex]
[tex] \rm \implies\displaystyle \rm \: { - 5}{ } = {A( - 5) } \\ [/tex]
[tex] \rm \implies\displaystyle \rm A = 1 \\ [/tex]
Thus ,
[tex] \displaystyle \int \rm \: \dfrac{2x - 1}{ (x + 2) (x - 3)} dx = \int\dfrac{1}{x + 2} dx + \int \dfrac{1}{x - 3} dx[/tex]
[tex] \rm = ln |x + 2| + ln |x - 3| + C[/tex]

. Maya went sledding down two hills. The first hill was 24 feet long. The second
hill was 432 inches long. How many feet in all did Maya sled on the two hills?
Remember to show your work.
Using the conversion factor we know that Maya sled down a total of 60 ft of both hills.
What is the conversion factor?A conversion factor is a number that is used to multiply or divide one set of units into another.
If a conversion is required, it must be done using the correct conversion factor to get an identical value.
For instance, 12 inches equals one foot when converting between inches and feet.
Conversion factors' function in the Medicare fee structure.
Every year, the CF is calculated using the CF from the year before, with the Medical Economic Index, the Update Adjustment Factor, Legislative Change, and Budget Neutrality factors are taken into account.
So, we know that:
1 inch = 0.0833333 ft
Then,
432 inches = 36 ft
Then, total ft Maya sled down:
= 24 ft + 36 ft
= 60 ft
Therefore, using the conversion factor we know that Maya sled down a total of 60 ft of both hills.
