The length of the rectangle is 7 cm and the width is 5 cm.

The whole distance covered by the rectangle's borders or its sides is known as its perimeter. As we know the rectangle will have 4 sides then the perimeter of the rectangle will be equal to the total of its four sides. And the unit will be in meters, centimeters, inches, feet, etc.        

The formula for the Perimeter of the rectangle is given by

Here we have

The length of a rectangle is 2cm greater than the width of the rectangle

And perimeter of the rectangle = 24 cm

Let x be the width of the rectangle

From the given data,

Length of the rectangle = (x + 2) cm  

As we know Perimeter of rectangle = 2(Length+width)

=> Perimeter of rectangle = 2(x+2 + x) = 2(2x +2)

From the given data,

Perimeter of rectangle =  24cm

=> 2(2x +2) = 24 cm

=> (2x +2) = 12     [ Divided by 2 into both sides ]

=>  2x = 12 - 2

=>  2x = 10

=>   x = 5         [ divided by 2 into both sides ]  

Length of rectangle, (x+2) = 5 + 2 = 7 cm

Therefore,

The length of the rectangle is 7 cm and the width is 5 cm.

Sin A = 2(Cos A)

Sin B = Cos A

Given,

We have ΔABC,

∠C is right angle

If Sin A = 2(Sin B)

We have to find Sin A and Sin B.

Trigonometric theorem

Sin θ = (opposite side / hypotenuse)

Cos θ = (adjacent side / hypotenuse)

Tan θ = (opposite side / adjacent side)

Here,

For Sin A, BC is opposite side and AB is hypotenuse.

For Sin B, AC is opposite side and AB is hypotenuse.

Then,

Sin A = 2(Sin B)

(BC / AB) = 2(AC / AB)

Cancel AB from both sides.

Then we get,

(BC / AC) = 2    -----------(1)

Let's find Tan A

Tan A = (opposite side / adjacent side)

For Tan A BC is opposite side and AC is adjacent side.

Tan A = (BC / AC)

From (1)

(BC / AC) = 2, That is Tan A = 2

Tan A = (Sin A / Cos A) = 2

Sin A / Cos A = 2

∴ Sin A = 2(Cos A)

Sin A = 2(Sin B)

So,

2(Sin B) = 2(Cos A)

Sin B = 2(Cos A) / 2

Sin B = Cos A

That is,

Sin A = 2(Cos A)

Sin B = Cos A

The probability that Chris's guess ends up being exactly 4 less than the result is approximately 0.5. So, the correct option is c).

The possible values of X are 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. The expected value of X can be calculated as

E(X) = (1/6) x 2 + (1/6) x 3 + (1/6) x 4 + (1/6) x 5 + (1/6) x 6 + (1/6) x 7 + (1/6) x 8 + (1/6) x 9 + (1/6) x 10 + (1/6) x 11 + (1/6) x 12

E(X) = 7

To be 4 less than the result, Chris's guess must be X - 4. Therefore, Chris's guess can be 2, 3, 4, 5, 6, 7, 8, 9, or 10.

The probability that Chris's guess ends up being exactly 4 less than the result can be calculated by finding the sum of the probabilities of getting X = 6, 7, or 8, since these are the only values of X that satisfy the condition that X - 4 is one of Chris's possible guesses

P(X = 6) = 5/36

P(X = 7) = 6/36

P(X = 8) = 5/36

P(Chris's guess is X - 4) = P(X = 6) + P(X = 7) + P(X = 8)

P(Chris's guess is X - 4) = 16/36

P(Chris's guess is X - 4) ≈ 0.44

Congress

The US congress is a combination of 2 components called the House of Representatives and the Senate.

Legislative Branch

The US government is made up of 3 branches. Both parts of Congress are a part of the legislative branch. The purpose of the legislative branch is to create laws. The houses of congress create bills and then vote on them to become laws. If a bill passes both the Senate and the House of Representatives, then it is eligible to become a law in the United States.

Differences between the Senate and House of Representative

While both the Senate and House are in Congress, they have slight differences. One of the main differences is the size of the bodies. The senate has 100 senators. Each state in America gets 2 senators. On the other hand, there are 435 representatives in the House. Representation in the House is based on the population of each state.

Answer:

x=10

Step-by-step explanation:

If an account has $32,000 and earns 11% interest compounded yearly, it will be worth $81,384.95 after 10 years.

This is calculated using the formula A = P(1 + r/n)^(nt),

where A is the final amount,

P is the initial amount,

r is the interest rate,

n is the number of times the interest is compounded per year, and t is the number of years.

In this case, P = $32,000, r = 0.11, n = 1 (compounded yearly), and t = 10.

Plugging these values into the formula,

we get A = $32,000(1 + 0.11/1)^(1*10) = $81,384.95.

Therefore, after 10 years, the account will be worth $81,384.95 with 2 decimal places due to the given information. It is important to note that compounded yearly typically results in higher returns compared to other compounding periods.

A mean of a normal distribution's upper bound of a 95% confidence interval is 58.11.

For the given question,

The confidence bound's upper limit (UCB) is determined as follows:

UCB =  μ + z(α/2)×σ/√n

Now, α/2 = (1 - 0.95)/2

α/2 = 0.025

z(α/2) = 1.96  (obtain from t-distribution table for degree of freedom)

1)The expected value for how much money John gets each day $6.25 and variance is $18.96.

This can be calculated as:

(0.5 * $5) + (0.35 * $10) + (0.15 * $20) = $6.25

The variance can be calculated as:

[(0.5 * ($5 - $6.25)^2) + (0.35 * ($10 - $6.25)^2) + (0.15 * ($20 - $6.25)^2)] = $18.96

2)The probability of saving more than $1000 over 100 days P(Z > 9.28) ≈ 0

To find the probability of saving more than $1000 over 100 days, we need to find the distribution of the total amount of money saved. The mean of this distribution would be

00 * $6.25 = $625, and the variance would be 100 * $18.96 = $1896.

The distribution of the total amount saved would be approximately normal by the central limit theorem. Using the normal distribution, we can calculate the probability of saving more than $1000 as:

P(Z > (1000 - 625) / sqrt(1896)) = P(Z > 9.28) ≈ 0

3) Probability of saving less than $400 is  P(Z < -14.14) ≈ 0

The expected amount of money John spends each day is $4. The total amount he spends over 100 days is 100 * $4 = $400. The standard deviation of the amount he spends each day is $0.75. Using the normal distribution, we can calculate the probability of saving less than $400 as:

P(Z < (400 - 625) / sqrt(100 * 0.75^2)) = P(Z < -14.14) ≈ 0

Step-by-step explanation:

A M function file 'tconvert.m', which can convert coordinates (x, y) into Polar from Cartesian coordinates. is:
"```matlab
function [theta, r] = tconvert(x, y)
```"

To create the M function file 'tconvert.m' that converts Cartesian coordinates (x, y) into Polar coordinates, follow these steps:

1. Open the MATLAB Editor or any text editor and create a new file named 'tconvert.m'.

2. In the file, start with the function declaration line: `function [theta, r] = tconvert(x, y)`.

3. Inside the function, write the conversion code using MATLAB's built-in functions:

  - Calculate the angle theta using `atan2(y, x)`, which returns the angle in radians.

  - Calculate the radius r using `sqrt(x^2 + y^2)`, which gives the distance from the origin.

4. End the function with the `end` keyword.

5. Save the file in a directory accessible by MATLAB.

The function 'tconvert' takes the Cartesian coordinates (x, y) as input and returns the corresponding Polar coordinates (theta, r). The angle theta represents the direction in radians, and the radius r represents the distance from the origin.

The function can be called from the MATLAB command window or from another script or function file.
