What is behavior of the standard deviation ?

The average squared difference between data points and their mean value is called variance, and it is the variance's square root that is used to calculate standard deviation. The symbol for standard deviation can be seen below.

Both the standard deviation and the variance are indicators of dispersion, but the standard deviation is more explicitly the typical distance between a data point and the mean. The majority of the data will be within one standard deviation of the mean. While the variance is not measured in the same units as the actual data, the standard deviation is

If mean deviation is 12, what is its standard deviation?

Lets look the problem .

Given ,

Mean deviation (MD) =12

Here is the inequality to calculate the standard deviation.

6QD=5MD=4SD ,

Where ,QD stands for the Quartile deviation.

SD stands for the standard deviation.

So,

Standard deviation =(5/4)*MD

=(5/4)*12

Natalee's mistake is that she has written the function incorrectly. In her function, she has multiplied the starting number of bacteria, 100, by the growth rate, 40%, to get the final number of bacteria. However, this is not correct because a growth rate of 40% means that the number of bacteria increases by 40% of the starting number, not by 40 itself.

To write the correct function, we can use the fact that a growth rate of 40% means that the final number of bacteria is 1.4 times the starting number. Therefore, the correct function for this scenario is y = 1.4 * 100 = <<1.4*100=140>>140. This function shows that the number of bacteria increases to 140 after experiencing a 40% increase in growth.

Answer:

The actual function for this scenario would be:

y = 100 * 1.40

Step-by-step explanation:

Natalee's mistake was that she didn't add 1 to the value of the increase. When you multiply a number by 1 plus the percentage increase, you get the correct result. In this case, the correct function would be:

y = 100 * 1.40

This function will show a 40% increase in the number of bacteria, starting with 100 bacteria. When graphed, the y-values will not be extremely high.

Step-by-step explanation:

AU is 20 degrees and ∠QPA is 35 degrees and ∠ARU is 40 degrees are the unknown measures.

A triangle is a three-sided polygon that consists of three edges and three vertices.

The incenter of a triangle is the intersection point of all the three interior angle bisectors of the triangle.

In the given triangle A is the incenter for triangle PQR.

By observing figure, AR is angle bisector of angle URK.

So,   ∠ARU = ∠ARK = 40 degree

Since, incenter point is equidistant from the sides of a triangle.

AT = AU = AK = 20

Since, PA is angle bisector of angle QPU.

So,  ∠QPA = ∠UPA

3x + 2 = 4x - 9

Subtract 3x and add 2 on both sides of equation.

4x - 3x = 9 + 2

x = 11

Now plug in x value in ∠QPA=3(11)+2

=33+2=35 degrees.

Hence, Measures ∠ARU is 40 degrees, AU is 20 degrees and ∠QPA is 35 degrees.

The equation y = 10x - 9 is rewritten in standard form as: -10x + y = -9.

A line's equation can be expressed in standard form as Ax + By = C. Here, A, B, and C are integers.

We are given the equation of a line as y = 10x - 9, which is expressed in slope-intercept form. We are asked to rewrite the equation in standard form. Follow the steps below:

y = 10x - 9 [given]

Subtract 10x from both sides of the equation:

y - 10x = 10x - 9 - 10x [subtraction property of equality]

y - 10x = -9

Rearrange the equation to fit the standard form:

Chi-square independence test.

A test that evaluates how well a model matches real observed data is the chi-square (2) statistic.

A chi-square statistic can only be calculated with data that is random, unprocessed, mutually exclusive, obtained from independent variables, and drawn from a sizable enough sample.

The outcomes of a fair coin toss, for instance, satisfy these requirements.

To test hypotheses, chi-square tests are frequently employed.

Given the size of the sample and the number of variables in the relationship, the chi-square statistic examines the size of any discrepancies between the expected results and the actual results.

According to the total number of variables and samples used in the experiment, degrees of freedom are utilized in these tests to assess whether a particular null hypothesis can be rejected. as well.

According to our question-

The independence of two variables, each of which is categorized into a variety of categories or attributes, is also tested using the chi square statistic.

When the cell probabilities rely on the unknown parameters, the goodness of fit test is relevant as long as the unknown parameters are substituted by their estimates and as long as one degree of freedom is subtracted for each estimated parameter.

Answer: y=4x-5     y=4x

Step-by-step explanation:

first we find the slope by using

(y2-y1)/(x2-x1)

(-1-3)/(3-2)

-4/1

-4

so we know the slope is -4

y=4x+b

now we can use either point but ill use (2,3)

we substitute to find b

3=4(2)+b

3=8+b

-5=b

so now we know that the y intercept is -5

so put it together

y=4x-5

if it passes through the origin

it would have the y-intercept of 0

so that equation just be

In the given sample mean, there are total 5 elements present.

An average of a group of data is called a sample mean.

A data set's central tendency, standard deviation, and variance can all be determined using the sample mean.

A population average can be determined using the sample mean, among other things.

Both the sample mean and sample median are helpful statistics for outlining a data set's core tendency.

The sample mean uses all of the data values because it is the arithmetic average.

Extreme values have no impact on the sample median, which simply uses one or two middle values.

So, we have the sample mean:

0 | 3 | 25 | 100 | 5,000

Now, in the given sample mean we can count that the number of values or the elements is 5.

The median of the probability density curve is (c) 14

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

Initial position = 1/12

Suppose we have a set {x₁, ..., xₙ}

The median is the number at the middle.

The difference between a set and a density curve is that the density curve is continuous, so getting the exact middle value can be harder.

In the given graph, we have

Constant density curve that goes from 8 to 20.

Because it is constant, the median will just be equal to the mean,

So, the median is the average between the two extreme values.

The average of two numbers a and b is calculated as

(a + b)/2

So we have

Median = (a + b)/2

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

Median = (20 + 8)/2

Median = 14
