200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.

Forecasted values are as follows: 1,500 and 1,400

Values in actuality: 1,200 and 1,500

Absolute differences:

|1,500 - 1,200| = 300

|1,400 - 1,500| = 100

Now, we calculate the MAD:

MAD = (300 + 100) / 2 = 400 / 2 = 200

Therefore, 200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

The reliability of the given system is 0.4033.

To calculate the reliability of a system, we need to multiply the reliability values of all the components in the system. In this case, we have a system composed of three components with the following reliability values:

Component 1: 0.90

Component 2: 0.90 0.90 0.85

Component 3: 0.85 0.85 0.92

To find the overall system reliability, we multiply these values together:

System reliability = Component 1 reliability x Component 2 reliability x Component 3 reliability

System reliability = 0.90 x (0.90 x 0.90 x 0.85) x (0.85 x 0.85 *x 0.92)

System reliability ≈ 0.90 x 0.6831 x 0.6528 ≈ 0.4033

Answer:

Step-by-step explanation:

y - 5 = 0(x + 2)

y - 5 = 0

y = 5

For the given function f(x), x-intercepts are 1,2 and 6 and the y-intercept is -12

Given :

\(f(x) = x^{3} -9x^{2} +20x -12 \\\)

One of the factors of f(x) is (x-6)

Dividing f(x) by (x-6), we get :
\(\frac{x^{3} -9x^{2} +20x -12 \\}{x-6} = x^{2} -3x +2\)

Now expanding, \(x^{2} -3x +2\)

\(x^{2} -3x +2 = x^{2} -2x -x +2 =x(x-2) -(x-2) = (x-2)(x-1)\)

Hence, \(x^{3} -9x^{2} +20x -12 = (x-6)(x-1)(x-2)\)

For x-intercept, f(x) = 0 . Then

(x-6)(x-1)(x-2) =0

x = 1,2 and 6

For y-intercept, x=0 in f(x)

f(0) = -12

Hence, the x-intercepts are 1,2, and 6 and the y-intercept is -12.

The senate has 4+22 = 26 members this year.

Let x be the number of Democrat members in the senate.

Last year, the number of Republican members was x+20

This year, the number of Republican members is (x+20) - 2 = x+18

This year, the number of members in the senate is 2/3*(x+18) = 2/3*x+12

So the number of members in the senate this year is x+12

To find the value of x, we can use the fact that the number of members in the senate this year is the same as last year.

x + (x + 20) = x + 12

x+x+20 = x + 12

2x = 8

x = 4

So the senate has 4 Democrat members and x+18 = 4+18 = 22 Republican members.

Step-by-step explanation:

So the final expression is: (change in y/y) = n (change in a/a).

We can start by taking the natural logarithm of both sides of the equation:

ln(y) = ln(aⁿ)

Using the rule that ln(aⁿ) = n ln(a), we can simplify this to:

ln(y) = n ln(a)

Next, we can take the derivative of both sides with respect to a:

d/d(a) ln(y) = d/d(a) (n ln(a))

Using the chain rule, we can simplify the right-hand side to:

d/d(a) ln(y) = n (1/a)

Now, we can multiply both sides by a/y:

a/y * d/d(a) y = n(a/y) * (1/a)

Latanya can use up to 5 gigabytes while staying within her budget.

To determine the number of gigabytes Latanya can use while staying within her budget, we need to write an inequality that represents her monthly cell phone bill.

Let x be the number of gigabytes she uses. Then, her monthly bill can be represented as:

35 + 4x < 55

This inequality represents her monthly bill, which is the flat cost plus the cost per gigabyte, being less than $55.

To calculate the value of x, we'll isolate x on one side of the inequality:

35 -35 + 4x < 55 -35

4x/4 < 20/4

x < 5

So, Latanya can use up to 5 gigabytes while staying within her budget.

Note that this solution is in terms of the number of gigabytes and not the total bill amount. The total bill amount would be 35 + 4x, which should be less than or equal to 55.

The true statements about nonregular languages are as follows:Option 3. Only A, B, and C are true.

The statement A says that there exists an FA that accepts the nonregular language {a^n b^n+1 where n ≥ 3}. It is a true statement. Because the language {a^n b^n+1 where n ≥ 3} is not a regular language. It can be proved by using the pumping lemma. Hence the statement A is true.

The statement B says that the nonregular language {a^n b^n where n ≥ 3} can be written as the regular expression a*b*. This statement is false because the language {a^n b^n where n ≥ 3} is not a regular language and it can not be written as the regular expression a*b*. Hence statement B is false.

The statement C says that the language accepted by an FA can be a nonregular language. It is a true statement. Because there exists a nonregular language that can be accepted by an FA. For example, the language {a^n b^n where n ≥ 0} is not a regular language. But it can be accepted by an FA. Hence statement C is true.

The statement D says that the reductio ad absurdum approach can be used to prove that a language is not regular. It is a true statement. Because the reductio ad absurdum approach is one of the methods to prove that a language is not regular. Hence statement D is true.

Step-by-step explanation:

Optically active compounds can rotate plane-polarized light in

A - Clockwise rotation

B - Counterclockwise rotation

C - Dextrorotatory

D - Levorotatory

Optically active compounds can rotate the plane of polarization of light, which can be either clockwise or counterclockwise. The direction of rotation is usually expressed as either dextrorotatory (abbreviated as +) or levorotatory (abbreviated as -), depending on whether the compound rotates the plane of polarization to the right or left, respectively.

For example, a compound that rotates the plane of polarization to the right (clockwise) is said to be dextrorotatory (+), while a compound that rotates the plane of polarization to the left (counterclockwise) is said to be levorotatory (-).

Therefore, A corresponds to clockwise rotation, B corresponds to counterclockwise rotation, C corresponds to dextrorotatory, and D corresponds to levorotatory.

Answer: Length = (15x + 20) / 5

Step-by-step explanation:

The area of a rectangle is calculated as length × width. Since the area of the rectangle is expressed as (15x + 20) square feet while the width of the rectangle is 5 feet, then the expression to represent the length of the rectangle will be:

Area = length × width

(15x + 20) = length × 5

Length = (15x + 20) / 5

Therefore, the expression is Length = (15x + 20) / 5.

Solving further, the length will be:

The percent increase in the flight increase is \(18.35\)%

Definition of percentages.

A percentage is a ratio of some value out of a hundred.

With this definition in mind, if \(20\)% of \(200\) students have a test tomorrow, then a total of \(40\) students have a test tomorrow.

Percentage Increase Calculation Example #1

For the first example, we find the percentage increase for the following scenario:

If your total savings of $\(60\) at the beginning of the week grew to $\(90\) by the end of the week, what is the percentage increase?

This is where our three-step process comes in:

Step 1: Find the difference in values ​​by subtracting the initial value from the final value.

In this case, the final value minus the initial value can be calculated as follows:

\(90 -60 = 30\)

So in this example, the difference between the two values ​​would be \(30\). Remember that when calculating the percentage increase, you will always subtract the smaller value from the larger value.

Step 2:Divide the difference by the initial number

The next step is to take the difference (\(30\) in this example) and divide it by the starting number (\(60\) in this example) like this:

\(30/60 = 0.50\)

Always express your answer as a decimal (this will make your life a lot easier when you get to step three).

Step 3: Multiply by \(100\)

The last step is to multiply the decimal result from step two by one hundred and express the final result as a percentage.

\(0.50 * 100 = 50\)

Final answer: 50% increase

That is all! Using three steps, you can conclude that there was a \(50\)% increase in the money you had from the beginning of the week to the end of the week.

Hence percent increase can be found as follows:

=$\((432-365)/365*100\)

=\(18.35\)%
