Answer:

100π - 192 or 122.159....

Step-by-step explanation:

In order to find the diameter we much first split the rectangle diagonally and find the hypotenuse using Pythagorean theorem.

a^2 + b^2 = c^2

16^2 + 12^2 = c^2

400 = c^2

c = 20

If the diameter of the rectangle is 20, the radius is just half of that which is 10. Then you just need to a do a basic calculation for area of a circle and then subtract out the area of the rectangle.

Area of circle = πr^2 = π(10^2) = 100π (keeping it in exact value since π is infinite)

Area of rectangle = lw = (16)(12) = 192

Area of shaded area = 100π - 192 (exact) = 122.159 (estimate)

Suppose you bought 45 shares of a telecommunications company 4 years ago at a price of $63.00 per share. You just sold it at $71.50 per share. How much money did you make? OOOO $377.50 $382.50 $387.50 $392.50 I don't know One attempt​

Answers

You made a profit of $382.50 from selling the 45 shares of the telecommunications company.

How to calculate the profit you made from selling the 45 shares of the telecommunications company

First we need to determine the total cost of purchasing those shares, and then subtract that from the total revenue from selling them.

The total cost of purchasing the 45 shares at a price of $63.00 per share is:

45 shares x $63.00 per share = $2,835.00

The total revenue from selling the 45 shares at a price of $71.50 per share is:

45 shares x $71.50 per share = $3,217.50

To calculate the profit, we subtract the cost from the revenue:

Profit = Revenue - Cost

Profit = $3,217.50 - $2,835.00

Profit = $382.50

Therefore, you made a profit of $382.50 from selling the 45 shares of the telecommunications company.

How many bundles of strip flooring are needed to cover a rectangular floor area 16 ft by 14 ft 6 in size if a bundle of strip flooring contains 25 sq​ ft, and if 30 ​% extra must be allowed for side and end​ matching?

Answers

If a bundle of strip flooring has 25 sq ft and 30% extra is provided for side and end matching, 12.2 bundles of strip flooring are required to cover a rectangle floor space 16 ft by 14 ft 6 in size.

How do you find the area of the rectangle?

Once the length and breadth of a rectangle are determined, the area is computed. The area of a rectangle may be calculated by multiplying its length and width.

In this question, because the rectangular floor has an area of 16 ft by 14 ft 6 in, we can compute the total area of the floor by multiplying 16 ft by 14 ft 6 in, which is 234 [tex]ft^{2}[/tex]. We also know that a strip flooring bundle comprises 25 square feet. As a result, we must determine how many bundles of strip flooring are required to cover the floor.

We must account for side and end matching, which is computed by increasing the total floor area by 30%. To determine the extra space required for side and end matching, multiply 234 ft2 by 0.3. This equates to 70.2 [tex]ft^{2}[/tex].

We can now compute the total area required to cover the floor. This is 234 [tex]ft^{2}[/tex] + 70.2 [tex]ft^{2}[/tex] = 304.2 [tex]ft^{2}[/tex].

Because each strip flooring bundle includes 25 square feet, we can divide 304.2 [tex]ft^{2}[/tex] by 25 to determine the total number of bundles required to cover the floor.

This corresponds to 12.2 bundles.

Therefore, 12.2 bundles of strip flooring are needed to cover a rectangular floor area 16 ft by 14 ft 6 in size, with 30% extra for side and end​ matching.

The solution for x in the trapezoid is x = 12

How to solve for x in the trapezoid?

The midsegment of a trapezoid is a line segment that connects the midpoints of the parallel sides of the trapezoid.

The midsegment of a trapezoid is parallel to the bases of the trapezoid and is equal in length to half the sum of the lengths of the two bases. That is:

DE = 1/2 * (KL + JM)

On a level field a telephone pole 24 feet tall casts a shadow 6 feet long. At the same time of day, another nearby telephone pole casts a shadow 18 feel long. How many feet tall is the second telephone pole?.

Answers

The second telephone pole is 72 feet tall. Since the ratio of the height of the first telephone pole to the length of its shadow is 24/6 = 4.

We can use this ratio to find the height of the second telephone pole.

If the second telephone pole casts a shadow of 18 feet at the same time of day, we can set up the following proportion:

height of second pole / length of shadow of second pole = height of first pole / length of shadow of first pole

Letting x be the height of the second pole, we can plug in the values we know and solve for x:

x / 18 = 24 / 6

Multiplying both sides by 18, we get:

x = 72

Therefore, the second telephone pole is 72 feet tall.

The answer is (e) 72.

Percentage of change in the stock's price since the beginning of the year is: 12.32%

What is stock's price?

The price at which a stock's share is currently trading on the market is referred to as the stock price. Every publicly listed company issues its shares at a price, which is an estimation of their value that, ideally, corresponds to the worth of the firm itself.

The market forces of supply and demand govern a company's share price once it becomes public and its shares begin trading on a stock exchange. Price increases will occur if there is a large demand for its shares. A stock's price might be reduced by sellers if the company's prospects for future growth appear uncertain.

Given that,

Closing price today = $21.20

Closing price on the previous trading day= $28.83

Difference between closing price today and closing price on the previous trading day= $21.20 - $28.83

= $7.63

What is complex plane?

The complex plane in mathematics is the plane made up of complex numbers, with real and imaginary numbers making up the x-axis (also known as the real axis) and the y-axis (also known as the imaginary axis) of the Cartesian coordinate system.

Complex numbers can be geometrically interpreted using the complex plane. They add like vectors when addition is applied. Polar coordinates make it simpler to represent the product of two complex numbers, whose magnitude or modulus is the sum of their absolute values.

The coordinates of the point A are (-3, -2).

If we extend the line from the origin to the point A it forms a right angled triangle with base = 3 and height = 2.

Using the Pythagoras theorem:

c² = a² + b²

Substituting the values:

c² = (2)² + (3)²

c = √13

If you took many random samples of a variable with a VERY SKEWED distribution, the means of your random samples would follow a (normal, uniform, skewed, or bimodal) distribution?

Answers

Answer:

Step-by-step explanation:

If you took many random samples of a variable with a BIMODAL distribution, the means of your random samples would follow a normal distribution.

If you took many random samples of a variable with a VERY SKEWED distribution, the means of your random samples would follow a normal distribution. This is due to the Central Limit Theorem, which states that as the sample size increases, the distribution of the sample means approaches a normal distribution, regardless of the shape of the underlying population distribution.

The Central Limit Theorem (CLT) is a fundamental theorem in statistics that states that, as the sample size increases, the distribution of the sample means approaches a normal distribution, regardless of the shape of the underlying population distribution. This means that even if the original population distribution is skewed, bimodal, or any other shape, the distribution of the sample means will tend towards a normal distribution as the sample size increases.

The reason for this is that the sample means are essentially an average of a number of independent random variables, and the normal distribution is the result of the combination of many independent random variables. When the sample size is large, the distribution of the sample means becomes very close to a normal distribution, even if the underlying population is far from normal.

In the case of a bimodal distribution, the sample means will still approach a normal distribution as the sample size increases, but the distribution may have a different mean and standard deviation than the original population.

In the case of a very skewed distribution, the sample means will also approach a normal distribution as the sample size increases, but the distribution may still be skewed, just less so than the original population.

In conclusion, the Central Limit Theorem states that the distribution of the sample means will tend towards a normal distribution as the sample size increases, regardless of the shape of the underlying population distribution.

Mrs Chong paid for a frying pan that cost $64 with some $10, $5 and $2 notes .If she used a total of 15 notes,how many $5 notes did she use?

Required process!
Thank you

Answers

For every $2 note used, Mrs. Chong used 3/5 of a $5 note. Since she used 15 notes in total, and the number of $2 notes used must be an integer, we can see that she used 10 $2 notes. That means she used 3/5 * 10 = 6 $5 notes.

What is Inequalities?

Inequalities are mathematical statements used to express the comparison between two values. Unlike equalities (e.g., 3 + 4 = 7), which use the "equals" sign (=), inequalities use symbols such as "greater than" (>), "less than" (<), "greater than or equal to" (>=), and "less than or equal to" (<=) to express a relationship between the values.

Let's call the number of $10 notes Mrs. Chong used as "x".

We know the total amount she paid was $64, and the number of notes used was 15, so we can set up an equation:

10x + 5y + 2z = 64

Where "y" is the number of $5 notes used and "z" is the number of $2 notes used. We know that x + y + z = 15 (because this is the total number of notes used).

We can substitute x = 15 - y - z into the first equation:

10(15 - y - z) + 5y + 2z = 64

Expanding the equation:

150 - 10y - 10z + 5y + 2z = 64

Combining like terms:

150 - 5y + 3z = 64

Subtracting 150 from both sides:

-5y + 3z = -86

Dividing both sides by -5:

y - (3/5)z = 17.2

So, for every $2 note used, Mrs. Chong used 3/5 of a $5 note. Since she used 15 notes in total, and the number of $2 notes used must be an integer, we can see that she used 10 $2 notes. That means she used 3/5 * 10 = 6 $5 notes.

Inverse function for the function f(x)= |x+5|, x>-5 is f⁻¹(x) = -5 ± x

What is inverse function?

An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by 'f' or 'F', then the inverse function is denoted by f-1 or F-1.

Given function,

f(x) = |x + 5| , x>-5

It can be written as

y = |x + 5|

Replacing x with y

x = |y + 5|

Solving for y

y + 5 = ± x

y = -5 ± x

Replacing y with f⁻¹(x)

f⁻¹(x) = -5 ± x

Hence, f⁻¹(x) = -5 ± x is the inverse function for function f(x)= |x+5|, x>-5

[tex]L = \displaystyle \lim_{\text{x}\to4}\frac{\text{x}^3-8\text{x}^2+20\text{x}-16}{\text{x}-4}\\\\\\L = \displaystyle \lim_{\text{x}\to4}\frac{(\text{x}-4)(\text{x}-2)^2}{\text{x}-4}\\\\\\L = \displaystyle \lim_{\text{x}\to4}(\text{x}-2)^2\\\\\\L = (4-2)^2\\\\\\L = 4\\\\\\[/tex]

Therefore,

[tex]\displaystyle \lim_{\text{x}\to4}\frac{\text{x}^3-8\text{x}^2+20\text{x}-16}{\text{x}-4}=4\\\\\\[/tex]

You can use graphing software like Desmos or GeoGebra to confirm the answer is correct. WolframAlpha is another good choice.

What work is done by each force? Joule HeatingConsider a metal at uniform temperature in a static uniform electric field E. An electron experiences a collision, and then, after a time t, a second collision. In the Drude model, energy is not conserved in collisions, for the mean speed of an electron emerging from a collision does not depend on the energy that the electron acquired from the field since the time of the preceding collision (assumption 4. Page 6). (a) Show that the average energy lost to ions in the second of two collisions separated by a time t is (eEt)2 2m. (The average is over all directions in which the electron emerged from the first collision. )(b) Show, using the result of Problem 1(b), that the average energy loss to the ions per collision is (eEt)2/m, and hence that the average loss per cubic centimeter per second is (ne2/m)E2=E2.
