What is the standard deviation of 1 2 3 4 5?

Answers

The standard deviation of

{1,2,3,4,5}=[52−112]12

=√2

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists.

The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

Like the variance, if the data points are close to the mean, there is a small variation whereas the data points are highly spread out from the mean, then it has a high variance.

Standard deviation calculates the extent to which the values differ from the average. Standard Deviation, the most widely used measure of dispersion, is based on all values.

Therefore a change in even one value affects the value of standard deviation. It is independent of origin but not of scale.

It is also useful in certain advanced statistical problems.

Let's develop a general formula then as a particular you get standard deviation of

1,2,3,4 and 5

If we have

{1,2,3,....,n}

and we need to find the standard deviation of this numbers.

Note that

Var(X)=1nn∑i=1 x2i−(1nn∑i=1xi)2

⇒Var(X)=1nn∑i=1i2−(1nn∑i=1 i)2

⇒Var(X)=1n⋅n(n+1)(2n+1)6−(1n⋅n(n+1)2)2

⇒Var(X)=(n+1)(2+1)6−(n+12)2

⇒Var(X)=n+12[2n+13−n+12]

⇒Var(X)=n+12⋅n−16

⇒Var(X)=n2−112

So, Standard deviation of

{1,2,3,....,n}

is

[Var(X)]12=[n2−112]12

In particular, your case the standard deviation of

{1,2,3,4,5}

=[52−112]12=√2.

What is the range of Y 3x 1?

Answers

{y | y ∈ ℝ} or (-∞, ∞) is the range of y = 3x + 1

What is range?

To determine the range of a group of observations, firstly arrange them in ascending order. The range may then be determined by comparing the difference between the highest and least numbers.

A function's range includes all conceivable values for y.  y = f(x) is the formula to determine a function's range (x). It is only a function in a relationship if each x value has exactly one y value.

Think about the function y = f(x). The function's range is defined as the range of all y values, from least to maximum. Substitute all possible values of x into the provided expression of y to see if it is positive, negative, or equal to other values.

For, y = 3x + 1

domain is all real numbers

so, {x | x ∈ ℝ} or (-∞, ∞)

range:

y = 3x + 1

or, -3x = -y + 1

or, 3x = y - 1

or, x = (y - 1)/3

The graph of 4x7 40x6 100x5 is a linear graph with a positive slope. The graph starts from the point (4,7) and increases in a linear fashion. At the point (40,6) the value of y is 6 and the value of x is 40. The graph then continues to increase as the value of x increases. At the point (100,5) the value of y is 5 and the value of x is 100. The graph of 4x7 40x6 100x5 is a linear graph with a positive slope, increasing from 4x7 to 100x5, and having a y-intercept of 0.The graph then continues to decrease in slope as x increases and reaches the point (40,6) and finally (100,5). This graph is a linear equation which can be written as

y = mx + b

where m is the slope and b is the y-intercept. . The y-intercept is the point where the graph crosses the y-axis and can be found by substituting 0 for x in the equation.The slope is calculated by subtracting the y-values and dividing by the x-values, which gives us a slope of -1/96. The y-intercept is calculated by substituting 0 for x in the equation, which gives us a y-intercept of 7.

At a local high school, the student population is growing at 12% a year. If the original population was 242 students, how long will it take the population to reach 300 students? Round to the nearest tenth of a year.

A. 0.7 Years
B. 3.2 Years
C. 1.9 Years

Answers

It will take 2 year the population to reach 300 students.

What is rounding to the nearest tenth?

Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5. To the nearest tenth, 4.6, for instance, is 4.624.

Given that, the initial number of students is 242.

The student population is growing at 12% a year.

The number of students that increases is 300 - 242 = 58.

Applying formula

I = PRT

I = The number of students that increased = 58

P = initial number of students = 242

T = Time

R = rate of increasing =12% = 0.12

Therefore,

58 = 242 × T × 0.12

T = 58/(242 × 0.12)

T = 1.997

T = 2.0 years

What is the difference between coefficient of standard deviation and coefficient of variation class 11?

Answers

Coefficient of Standard Deviation vs. Coefficient of Variation: When to Use Each

The standard deviation is most commonly used when we want to know the spread of values in a single dataset.

However, the coefficient of variation is more commonly used when we want to compare the variation between two datasets.

For example, in finance the coefficient of variation is used to compare the mean expected return of an investment relative to the expected standard deviation of the investment.

For example, suppose an investor is considering investing in the following two mutual funds:

Mutual Fund A: mean = 9%, standard deviation = 12.4%

Mutual Fund B: mean = 5%, standard deviation = 8.2%

The investor can calculate the coefficient of variation for each fund:

CV for Mutual Fund A = 12.4% / 9% = 1.38

CV for Mutual Fund B = 8.2% / 5% = 1.64

Since Mutual Fund A has a lower coefficient of variation, it offers a better mean return relative to the standard deviation.

Here’s a brief summary of the main points in this article:

Both the standard deviation and the coefficient of variation measure the spread of values in a dataset.

The standard deviation measures how far the average value lies from the mean.

The coefficient of variation measures the ratio of the standard deviation to the mean.

The standard deviation is used more often when we want to measure the spread of values in a single dataset.

The coefficient of variation is used more often when we want to compare the variation between two different datasets.

Answers

We can find the missing value of a triangle on a calculator in the following way,

If the value is a side of a triangle and the triangle is a right-angle triangle, we apply the Pythagoras Theorem. The formula of this theorem is a²+ b²= h², where h is the hypotenuse of the triangle, and a and b are the remaining two sides.

If the triangle is any other triangle, we use the law of sine, which is:

a/sin(A)= b/sin(B)= c/sin(C), where a, b, and c are sides of the triangle and A, B, and C are the angles opposite to the respective sides.

If the value is an angle of the triangle, we use the formula

x=180-(y+z), where x is the missing angle, and y and z are the remaining two angles of the triangle.

find the coefficient of the term containing x^11 in the expansion of the binomial (x-3)^12

Answers

The coefficient of x^11 in the binomial expansion of (x - 3)^12 is -36.

What is binomial expansion?

The binomial theorem in basic algebra explains how a binomial's powers can be expanded algebraically.

Exponents of x and y added together always equal n. The binomial coefficients that are equally spaced from the start and end are equal, i.e., nC0 = nCn, nC1 = nCn-1, nC2 = nCn-2, etc.

Consider, the given expression (x - 3)^12

We have to find the coefficient of x^11 in the expansion of (x - 3)^12.

Applying the binomial theorem,

(a + b)^n =  Σ(i = 0 to n) nCi a^(n- i)b^i

Here a = x, b = -3.

⇒ (x - 3)^12 =  Σ(i = 0 to 12) 12Ci x^(12 - i)(-3)^i

[tex](x -3)^1^2 = x^ 1^2-36^1^1+59x^1^0 - 5940x^9 + 40095x^8 - 192456x^7+ 673596x^6 - 1732104x^5 + 3267695x^4-4330260x^3 + 3897234x^2- 2125764x+531441[/tex]

Hence, the coefficient of x^11 in the binomial expansion of (x - 3)^12 is -36.

Which is an expression for the derivative of P(x)=f(x)/1-f(x)?

Answers

Here the correct expression for the derivative of P(x) is: option B

What is mean by derivative?

The fact that the initial function f implies a second, distinct function f′(x) gives origin to the name "derivative" (x). As a result, we have deduced one from another. When we deduce one from the other, the terms differential, etc. pertain more to the real mathematics that is taking place.

The definition of a derivative in mathematics is a technique for displaying the simultaneous rate of change. The amount by which the provided function is changing at a certain instant is thus represented by it.

The following are some uses for derivatives: to ascertain the pace at which one item is changing in relation to another. The saddle points of a function are used to calculate maximum and minimum. to establish a function's concavity and convexity.

P(x) = [tex]\frac{f(x)}{1-f(x)}[/tex]

or, [tex]\frac{d}{dx} P(x) =[/tex] [tex]\frac{d}{dx} \frac{f(x)}{1-f(x)}[/tex]

How to determine the algebraic expression to represent this situation

From the question, we have the following parameters that can be used in our computation:

Number of baskets = 8

Pears in each basket = 11

The total number of pear is calculated as

The total number of pear = Number of baskets * Pears in each basket

Substitute the known values in the above equation, so, we have the following representation

The total number of pear = 8 * 11

Evaluate

The total number of pear = 88

Represent the students with x

What is the proportion method formula?

Answers

Two ratios are referred to as being in proportion if they are the same. If the four elements are a, b, c, and d in that order, then a : b :: c : d = a/b = c/d.

Describe the method of proportion?When two ratios are equal, they are in proportion, based on the definition of proportion. When determining if two ratios and fractions are equivalent, this proportion formula is performed.

The following formulas also relate to proportion:

a : b :: c : d = a/b = c/d

In which,

a, d = Extreme termsb, c = Mean terms

The ratio of averages to extremes is 1:1. You can write this as ad = bc.

Two additional proportional formulas that depend on either direct or indirect variation are available. If two numbers x and y are all in direct proportion, y = kx, and when they are in indirect proportion, y = k/x, with k serving as the proportionality constant in both cases.
