What is error?

Error is the difference between an actual value and an estimate, or approximate, representation of that value in applied mathematics. The discrepancy between the population's average and the average of a sample taken from that population is a frequent example in statistics. The discrepancy between an irrational number's true value and the values of rational expressions like 22/7, 355/113, 3.14, or 3.14159 serves as an example of round-off error in numerical analysis. A truncation error happens when an infinite series is ignored for all but a small number of terms. For instance, the sum of the infinite series can be used to express the exponential function ex.

df-error = (df-within treatment) - (df-subjects)

df-subjects = n - 1 = 5 - 1 = 4 {n is the no of subjects}

df-within treatment = 12

df-error = 12 - 4 = 8

Akash estimate of 700cm of plastic trim is not sensible because he needs more than that.

The diagram of the question is below.

The window is made of a semi circle and a rectangular. More like a composite figure.

Composite figure are 2 dimensional figures that combines two or more two dimensional figures. Therefore, the part the plastic trim was applied are those sharp line region. It's like finding the perimeter of the whole shaded region.

He estimate he will need 700 cm of plastic trim in total. Therefore, let check if his estimate is sensible.

Therefore,

radius = 59 cm

perimeter of the rectangle = 2(113) + 2(118) = 462 cm

perimeter of the semi circle = 3.14 × 59 = 185.26 cm

Two radius = 2(59) = 118 cm

Therefore,

whole perimeter where plastic trim will be applied  = 462 + 185.26 + 118 =  765.26 cm.

Answer:

The radius of the circle is 5 cm

Step-by-step explanation:

The given parameters are;

The distance of the point P from the center of the circle = 13 cm

The length of the tangent from the point P to the circle = 12 cm

The circle diagram is created with Microsoft Visio, from which we have;

The line drawn from the center to the point P, the tangent line from P to the circle and the radius of the circle form a right triangle

The length of the radius of the circle, r, is given by Pythagoras theorem as, follows;

r = √((13 cm)² - (12 cm)²) = 5  cm

Therefore, the radius of the circle = r = 5 cm.

Answer:

B. -113 inches

Step-by-step explanation:

First you have to find the radius of the two pizzas. The radius is half of the diameter. So, the first pizza would have a radius of 8 inches, since 8 is half of 16. The second pizza would have a radius of 10 inches, since 10 is half of 20. Then you would use the area formula to find the area of the two pizzas. The area formula is A=3.14R^2. The area of the first pizza is 201.06. The area of the second pizza is 314.16. Then you subtract those two numbers to get -113.1. The answer is -113 inches.

Answer:

B

Step-by-step explanation:

The average rate of change in the closed interval [ a, b ] is

\(\frac{f(b)-f(a)}{b-a}\)

Here [ a , b ] = [ 15, 35 ]

and f(b) = f(35) = 400 ← from graph

f(a) = f(15) = 200 ← from graph

Then average rate of change is

\(\frac{400-200}{35-15}\) = \(\frac{200}{20}\) = 10 m/ s → B

The UCL (Upper Control Limit) using sigma = 3 for this process would be 30. The UCL utilizing sigma=3 for this process would be 28.036.

In statistical process control, the upper control limit (UCL) is utilized as a device to identify when to stop a process due to a high variation.

A process that exceeds its UCL will result in defective or inconsistent items, which should be avoided.

Marble Inc. produces high-end countertops from a variety of materials. The company employs the process of randomly selecting one countertop to count the number of blemishes as a means of monitoring the quality of its production processes.

The formula for calculating UCL is as follows: UCL = average of blemishes + 3 × standard deviation For ten samples with a different number of blemishes in each sample, the UCL is determined.

Using the given formula for UCL using sigma= 3: UCL = (2+3+4+5+6+7+8+9+10+17)/10 + 3 × √[(2-9.1)² + (3-9.1)² + (4-9.1)² + (5-9.1)² + (6-9.1)² + (7-9.1)² + (8-9.1)² + (9-9.1)² + (10-9.1)² + (17-9.1)²]/10UCL = 28.036

Inference is referred to as all the data collected in a particular study.

Etymologically, the word "infer" means to "carry ahead." Inferences are stages in reasoning that connect premises to logical conclusions. The dichotomy between deduction and induction in inference theory, which dates at least to Aristotle in Europe, is a classic one (300s BCE). Deduction is inference that results in logical conclusions from premises that are known to be true or that are presumed to be true, while the logic of correct inference is investigated. A universal conclusion is inferred by induction from specific evidence. Contradistinguishing abduction from induction, Charles Sanders Peirce is credited with identifying a third sort of inference. Researchers in the domains of logic, argumentation studies, and cognitive psychology traditionally study human inference (i.e., how people draw conclusions); artificial intelligence researchers create automated inference systems to mimic human inference.

Answer:

The rate "20 pounds per 4 feet", doesn't belong with the other three because you get "5 pounds per foot" for the unit rate and for the other three, you get "4 pound per foot" for the unit rate.

Step-by-step explanation:

Unit rate = How much of something per 1 unit of something else

We write this as a ratio with a denominator of one

In this case, we are using "pound per foot"

1. "8 pounds for every 2 feet"

You can find the unit rate by dividing the first term of the ratio by the second term

\(\mathrm{\dfrac{ 8\:pounds }{ 2\:feet }}\)

Simplify

\(\mathrm{4\:pounds}\)

Unit rate = 4 pounds per foot

2. "12 pounds per 3 feet"

First, write the rate as a fraction

\(\mathrm{\dfrac{ 12\:pounds }{ 3\:feet }}\)

Next, divide the numerator and denominator by 3

\(\mathrm{\dfrac{ 12\:pounds \div 3 }{ 3\:feet \div 3 }}\)

Lastly, simplify and turn the denominator equal to 1

\(\mathrm{\dfrac{ 4\:pounds }{ 1\:foot }}\)

Unit rate = 4 pounds per foot

3. "20 pounds per 4 feet"

First, write the rate as a fraction

\(\mathrm{\dfrac{ 20\:pounds }{ 4\:feet }}\)

Next, divide the numerator and denominator by 4

\(\mathrm{\dfrac{ 20\:pounds \div 4 }{ 4\:feet \div 4 }}\)

Lastly, simplify and turn the denominator equal to 1

\(\mathrm{\dfrac{ 5\:pounds }{ 1\:foot }}\)

Unit rate = 5 pounds per foot

4. "24 pounds for every 6 feet"

You can find the unit rate by dividing the first term of the ratio by the second term

\(\mathrm{\dfrac{ 24\:pounds }{ 6\:feet }}\)

Simplify

\(\mathrm{4\:pounds}\)

Unit rate = 4 pounds per foot

The rate that doesn't belong is "20 pounds per 4 feet"

The points on the graph where y equals zero represent the solutions to the original equation.

However, please note that the equation you provided,

\(x^3 - 2x^2 - 11x + 12 = x^3 - 13x - 12\), simplifies to \(-2x^2 + x + 24 = 0\). The original equation \(x^3 - 2x^2 - 11x + 12 = x^3 - 13x - 12\) does not have any variable x terms on the right side, which results in the elimination of all x terms in the simplified equation.

To graph the system of equations that can be used to solve the equation \(x^3 - 2x^2 - 11x + 12 = x^3 - 13x - 12,\)

we need to rewrite the equation in a form that represents a system of equations.

Rearranging the equation, we get:

\(x^3 - 2x^2 - 11x + 12 - (x^3 - 13x - 12) = 0\)

Simplifying:

\(-2x^2 + 2x - x + 24 = 0\)

Combining like terms:

\(-2x^2 + x + 24 = 0\)

Now, let's represent this equation as a system of equations by setting the left side of the equation equal to y:

\(y = -2x^2 + x + 24\)

We can then graph this equation using a coordinate plane. The x-axis represents the values of x, and the y-axis represents the corresponding values of y.

By plotting points on the graph  values based on various of x, we can obtain the graph of the equation\(y = -2x^2 + x + 24.\)

The number of rabbits that must be sold if they want to be fed for 15 more days is 150 rabbits.

In a farm, there is food to feed 300 rabbits for 60 days.

Let x be the number of rabbits that must be sold if they want to be fed for 15 more days.

From the given data, we have the following equation:

300 * 60 = (300 - x) * 75

The equation represents the amount of food for 300 rabbits that can last 60 days is equal to the amount of food for 300 - x rabbits that can last 75 days.

Solving for x, we get:

x = 150 rabbits

Hence, the number of rabbits that must be sold if they want to be fed for 15 more days is 150 rabbits.

Step-by-step explanation:

The probability of both events occurring is P(A ∩ B) = P(A)P(B) = 0.16^2 = 0.0256.

The event of getting a "2" and the event of getting a "5" on the first roll of a die are mutually exclusive events because they cannot both occur in the same trial. The probability of either of these events occurring is P(A) = 0.16, and the probability of both events occurring at the same time is P(A ∩ B) = 0.00.

The event of getting a "2" on the first roll and the event of getting a "5" on the second roll of a die are independent events. This can be confirmed using the formula P(A ∩ B) = P(A)P(B). The probability of getting a "2" on the first roll is P(A) = 0.16 and the probability of getting a "5" on the second roll is P(B) = 0.16. Thus, the probability of both events occurring is P(A ∩ B) = P(A)P(B) = 0.16^2 = 0.0256.
