Yesterday 160 guest at a hotel called for room service, and 240 guest did not called for room service. What is the percentage of the guest at this hotel called for room service yesterday?

Options

A: 60%
B: 33%
C: 40%
D: 67%

Please help!

Answer: -50

Step-by-step explanation:

5 - 6 / 5p = 125 degrees

1/2p = ?

First, subtract 5 from both sides, that way, the 5 on the left side will cancel out.

-6/5p = 125-5 degrees

-6/5p = 120 degrees

now, multiply 5p on both sides.

-6 = 120 * 5p degrees

-6 = 600p degrees

divide 600 on both sides

-6/600 = p degrees

-0.01 = p degrees

p = -0.01

1/2p = 1 / -0.02 = -50

The initial value problem, 2y″ + y = f(t), y(0) = 0, y′(0) = −1, where f(t) is defined as {2, 0 < t ≤ 2, 0, t > 2}, can be solved using Laplace transforms.

To solve the initial value problem using Laplace transforms, we first take the Laplace transform of the given differential equation. Applying the Laplace transform to the equation, we get 2s²Y(s) + Y(s) = F(s), where Y(s) and F(s) are the Laplace transforms of y(t) and f(t) respectively.

Next, we substitute the initial conditions y(0) = 0 and y′(0) = −1 into the transformed equation. Using the Laplace transform property for initial value conditions, we have Y(s) = Y(s) - 1/s.

Simplifying the equation, we can express Y(s) in terms of F(s) as Y(s) = F(s) / (2s² + 1) + 1/s.

Finally, we need to take the inverse Laplace transform of Y(s) to obtain the solution y(t). The inverse Laplace transform of F(s) / (2s² + 1) can be determined using partial fraction decomposition, and the inverse Laplace transform of 1/s is simply a ramp function.

Thus, by taking the inverse Laplace transform of Y(s), we can obtain the solution y(t) for the given initial value problem.

Answer:

y = 38

x = 18

Step-by-step explanation:

Equation 1. x + y = 56

Equation 2. x + 2y = 94​

We can use substitution

Let's create equation 3: 56 - y = x

Now using equation 3, substitute equation 2.

Equation 2 is now written as:

56 - y + 2y = 94

56 + y = 94

y = 38

Given the value of y, substitute equation 1 and find x

x + 38 = 56

x = 18

The correcting answer is - Since 5/6 is a repeating decimal, Miguel should convert the decimal -0.6 to a fraction and multiply the fractions.

Fractions represent the parts of a whole or collection of objects.

A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.

Now the given mixed fraction is,

-0.6(5/6)

Now since 5/6 is a repeating decimal,

Therefore converting 0.6 into fraction, we get

0.6 = 6/10

Therefore, -0.6(5/6) = -(6/10)*(5/6)

Rearranging we get,

-0.6(5/6) = -(6/6)*(5/10)

⇒ -0.6(5/6) = -1*(5/10)

or, -0.6(5/6) = -(5/10)

simplifying 5/10 we get,

-0.6(5/6) = -(1/2)

Thus, the correcting answer is - Since 5/6 is a repeating decimal, Miguel should convert the decimal -0.6 to a fraction and multiply the fractions.

You need to have a password with 5 letters followed by 3 odd digits between 0 and 9, inclusive, then the 473,616,000 choices are used.

It is clear from mathematical and statistical logic that the question was written incorrectly and that some of the digits were repeated. Thus, the appropriate query is:

"You need to have a password with 5 letters followed by 3 odd digits between 0 and 9, inclusive. If the characters and digits cannot be used more than once, how many choices do you have for your password?"

So,

We can write,

We all know that there are 26 letters available in the alphabet and there are just 5 numbers between 0 and 9.

We are now given the situation of how many passwords can we make out of the criteria of having 5 letters that cannot be repeated and 3 odd digits from 0-9.

We cannot repeat the numbers and letters, thus our password will look something like this, LLLLLNNNN, where L is a letter and N is a number. Let us note that  we cannot use the characters and digits more than once.

This is how we will solve the probable number of passwords.

= 26 x 25 x 24 x 23 x 22 x 5 x 4 x 3

5 letters from 26 with no repetition => 26*25*24*23*22 different choices.

Odd digits are 1, 3, 5, 7 and 9 => 5 different digits to choose

3 digits from 5 with no repetition => 5*4*3 = 60

Then, the total number of choices is: 26*25*24*23*22*60 = 473,616,000

Therefore,

You need to have a password with 5 letters followed by 3 odd digits between 0 and 9, inclusive, then the used choices are = 473,616,000

If the mean is greater than the median, the data is likely Right-skewed.

In mathematics, the mean is the average of a set of data, which is calculated by adding all the numbers together and then dividing the result by the total number of numbers. Right-skewed distributions have long right tails and are characterized by having a mean that is greater than the median. There are two different sorts of means that may be calculated: the arithmetic mean and the geometric mean. The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of integers in the set.

Therefore, the answer is right-skewed. A data set that is skewed to the right is one where the tail to the right of the data clusters is longer than the tail to the left of the data clusters. This means that the data set will have a mean value that is greater than the median.

Approximately 28.81% of callers are on hold for at least 5.4 minutes.

The percentage of callers who are on hold for at least 5.4 minutes can be determined by calculating the z-score and finding the area under the normal curve to the right of that z-score.

First, we need to calculate the z-score for a caller who is on hold for 5.4 minutes:

z = (5.4 - 4.9) / 0.9 = 0.56

Next, we can use a standard normal distribution table or calculator to find the area under the curve to the right of the z-score. The area to the right of 0.56 is 0.2881.

Therefore, approximately 28.81% of callers are on hold for at least 5.4 minutes.

Bond

Step-by-step explanation:

A promissory note or a promise to repay a certain amount of money at some point in the future is basically a bond.

A bond is a debt security that represents a loan made by an investor to a borrower, which is usually a corporation or government agency. It is a fixed-income investment, meaning that the borrower promises to pay a specific amount of interest over a set period of time and return the principal amount of the loan on the date of maturity. Bonds are issued for various purposes, such as raising capital, funding new projects, or refinancing debt.

CD (Certificate of Deposit) is a savings instrument issued by a bank or credit union that generally pays a fixed rate of interest over a set term. Mutual fund is an investment vehicle that pools money from multiple investors to purchase a portfolio of securities, such as stocks, bonds, or both. Stock is an ownership share in a company that represents a claim on part of the company's assets and earnings.

The result after synthetic division is 2x³ - 5x² - 4x + 2 and the remainder is -26/(x - 6).

When the divisor is a linear factor, the synthetic division is used to perform the division operation on polynomials.

To perform synthetic division, we set up the following table:

 6 | 2  -17  26  26  -2

    |    12  -30  -24

    |-----------------

    2  -5   -4   2  -26

Therefore, when we divide 2x⁴− 17x³ + 26x²+ 26x − 2 by x − 6 using synthetic division, we get:

2x³ - 5x^2 - 4x + 2 - 26/(x - 6)

So the quotient is 2x³ - 5x² - 4x + 2 and the remainder is -26/(x - 6).

No, (x - 2) is not a factor of f(x) = x³ - 2x² + 2x + 3.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ f (x) = x³ - 2x² + 2x + 3

And, The factor is (x - 2)

Now, If (x - 2) is factor of function then x = 2 satisfy the function.

Hence, We can check as,

⇒ f (x) = x³ - 2x² + 2x + 3

Put x = 2

⇒ f (2) = 2³ - 2 (2)² + 2 × 2 + 3

⇒ f (2) = 8 - 8 + 4 + 3
