deviation

data: 1, 1, 3, 5, 5, 6, 8, 11

The **mean absolute **deviation is 2.5.

The **average** **distance between **each **data **value and the **mean **is known as the mean **absolute deviation **(MAD) of a data collection. A **measure **of **variance **in a **data** **collection **is the mean absolute deviation. We may determine how "**spread** **out**" the **values **in a **data **collection are by looking at the mean absolute deviation.

How to calculate the **mean deviation** from the **mean**:

Given **data**:1, 1, 3, 5, 5, 6, 8, 11

So, **mean** of the **data **is

= 1+ 1 +3 +5 +5+ 6+ 8 +11 / 8

= 40 /8=

5

Now, Mean **absolute** **deviation **is

= | 1-5| + |1-5| + |3-5 | + |5-5| + |5-5| + |6-5| + |8-5| + |11-5|/ 8

= 4 + 4 + 2+ 0 + 0+ 1 + 3 +6 /8

= 20/8

=2.5

Hence, the **mean absolute** **deviation **is is 2.5.

Write a function and use a table and graph to predict when the population will reach 20,000

The formula for exponential growth is expressed as

y = a(1 + r)^t

where

y is the population after t years

ais the initial population

r is the growth rate

t is the number of years

From the information given,

a = 350

r = 14% = 14/100 = 0.14

By substituting these values into the equation, the function to model th growth rate is

y = 350(1 + 0.14)^t

**y = 350(1.14)^t**

We would substitute values of t into the equation to determine corresponding values of y. We have

For t = 2, y = 350(1.14)^2 = 454.86

For t = 6, y = 350(1.14)^6 = 768.24

For t = 10, y = 350(1.14)^10 = 1297.52

We would plot these values of y on the y axis and the corresponding values of t on the x axis. The graph is shown below

The time when the population will reach 20000 would be the value of x at the point where y = 20000 on the graph. It is around y = 30.87

Thus, **the population will reach 20000 in approximately 31 years**

We can confirm this by solving the equation. We have

20000 = 350(1.14)^t

20000/350 = 1.14^t

57.14 = 1.14^t

Taking natural log of both sides, we have

ln 57.14 = ln1.14^t = tln1.14

t = ln 57.14/ln1.14

**t = 30.87505**

This is called **matrix multiplication**.

Now consider the **matrixes** of the form A = [tex]\left[\begin{array}{cc}0&x\\0&0\end{array}\right][/tex]

Then A² = [tex]\left[\begin{array}{cc}0&x\\0&0\end{array}\right][/tex] x [tex]\left[\begin{array}{cc}0&x\\0&0\end{array}\right][/tex]

The line is given by 3x + 6y = 8

To find the slope and the y-intercept, we must rewrite the equation in the form y = ax + b, where a is the slope and b is the y-intercept.

The first step is subtract 3x from both sides of the equation:

3x + 6y - 3x = -3x + 8

6y = -3x + 8

Then, we divide both sides by 6:

6y/6 = (-3x + 8)/6

y = -x/2 + 4/3

Therefore, the slope is -1/2 and the y-intercept is 4/3

A **parabola** is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line. The vertex form of a quadratic equation is y = a (x h) 2 + k as opposed to the regular quadratic form, which is an x 2 + b x + c = y. In both cases, the variables that indicate whether the parabola is facing up (+ a) or down ( a) are y, the y-coordinate, x, and a.

Given Data

The costs of repairing iPads in UAE are normally distributed with a standard deviation 73 Dhs. If 8% of the costs exceed 279 Dhs, find the mean of the costs. Round your answer to the nearest diham.

The costs of repairing** iPads in UAE** are normally distributed with a standard deviation of 73 Dhs. If 8% of the costs exceed 279 Dhs, then the** mean of the costs **is** 1.405072**

The mean of the Costs stands for the typical **sum of money **spent on a product's production. Depending on how many units are made, this amount may change.

Let X be the price of fixing** iPads** in the UAE (in Dhs)

X ~ N (μ, σ = 73)

if 8% of the costs are greater than 297 Dhs.

P (X > 297) = 8%

P(X > 297) = 0.08

We must determine the **mean value (μ)**

P (X > 297) = 0.08

P [(X - μ) / σ > (297 - μ) / 73] = 0.08

P [Z < (297 - μ) / 73] = 0.08

P [Z < (297 - μ) / 73] = 1 - 0.08

P [Z < (297 - μ) / 73] = 0.92

(297 - μ) / 73 = Z⁻¹(0.92)

(297 - μ) / 73 = 1.405072 (Using R software)

297 - μ = 73 * 1.405072

μ = 297 - (73 * 1.405072)

μ = 297 - 102.5702

μ = 194.4298

**μ ≅ 194**

Therefore, the **mean of the cost (μ) = 194 dhs.**

**What is polygon?**

A **polygon** is a form of planar figure in geometry and is defined as a **closed polygonal** chain made up of a finite number of straight line segments. A region that is enclosed by a **bounding plane, a bounding circuit, or both is referred to as a polygon**. The portions of a polygonal circuit are referred to as its **edges or sides**.

To check the polygon EFGH is a square or not, first to find the length of each side of polygon.

If the length of each side is equal then the polygon EFGH is a square.

(Since length of each side of square is equal).

We know,

[tex]d \sqrt{(x_2-x_1)^2 + (y_2 - y_1)^2}[/tex]

where,

d = distance

[tex](x_1, x_2)[/tex] = Coordinates of the first point.

[tex](x_2, y_2)[/tex]* = *Coordinates of the second point.

So,

[tex]EF = \sqrt{(3-(-2))^2 + (3.5-3.5)^2} = \sqrt{25 + 0} = 5[/tex]

[tex]FG = \sqrt{(3-3)^2 + (-1.5-3.5)^2 } = \sqrt{0 + 25} = 5[/tex]

[tex]GH = \sqrt{(-2-3)^2 + (-1.5-(-1.5))^2} = \sqrt{25 + 0} = 5[/tex]

[tex]EH = \sqrt{(-2-(-2))^2 + (-1.5-3.5)^2} = \sqrt{0 + 25} = 5[/tex]

A map state where your friend lives have a scale 1/2 inch: 10 miles.

Your friend measured the distance between her town and the state capital on the map. Her measurements were 4 1/2 inches. Based on your friend's measurement, what is the actual distance in miles between her town and the state capital?

The actual **distance** is 90 miles between the **town** and the state **capital** based on the scale of the map

1/2 inch on the **map** = 10 miles

So, 1 inch = 20 miles

Distance between the town and **state** capital = 4 1/2 inches

The mathematical relationship between a small unit of measurement on a map, such as an inch or centimetre, and the corresponding real-world unit of distance, such as a kilometre or a mile, is known as a map **scale**.

The actual distance in miles between the town and the state capital is given by:

Distance between town and state capital* Scale of the map

= 4.5*20

= 90 miles

An architect is standing 250 feet from the base of a building and would like to know the height of the building. If he measures the angle of elevation to be 55°, what is the approximate height of the building? Round any intermediate calculations if needed to know less than six decimal places and round the final answer to the nearest 10th of a foot

see the figure below to better understand the problem

we have that

[tex]\begin{gathered} tan55^o=\frac{h}{250}---->\text{ by TOA} \\ \\ solve\text{ for h} \\ h=250*tan55^o \\ h=357.0\text{ ft} \end{gathered}[/tex]The answer is 357.0 feetOutcomeAnswer the following. Round your answers to the nearest thousandths.Number of SpinsExplanationCheckRed(a) From Donna's results, compute the experimental probability of landing on yellow.394аYellowJ420(b) Assuming that the spinner is fair, compute the theoretical probability of landing on yellow.(c) Assuming that the spinner is fair, choose the statement below that is true.O With a large number of spins, there might be a difference between the experimental andtheoretical probabilities, but the difference i need help with this math problem

**ANSWERS**

**(a) 0.420**

**(b) 0.400**

**(c) With a large number of spins, there might be a difference between the experimental and theoretical probabilities, but the difference should be small**

**EXPLANATION**

**(a)** The experimental probability is given by,

In this case, Donna spun the dial 1000 times and 420 times it landed on yellow,

[tex]P_{exp}=\frac{420}{1000}=0.420[/tex]Hence, **the ****experimental**** probability of landing on yellow is ****0.420**.

**(b)** The theoretical probability is given by the geometry of the spinner and, if it is fair, the number of yellow sections,

In this case, the spinner is divided into 10 equally sized slices, and 4 of them are yellow,

[tex]P_{th}=\frac{4}{10}=0.400[/tex]Hence, **the ****theoretical**** probability of landing on yellow is ****0.400**.

**(c)** As we can see in parts a and b, for 1000 trials, the experimental and theoretical probabilities are almost the same - i.e. there is a small difference. This is known as the **law of large numbers** which states that if the number of trials of an experiment is large, the experimental probability of each event should be close to the theoretical probability.

Hence, **the ****true**** statement is the first one: ****with a large number of spins, there might be a difference between the experimental and theoretical probabilities, but the difference should be small**.
