Scientific notation
The Scientific notation of [tex]$0.09 \cdot\left(9 \times 10^{-4}\right)$[/tex] be 0.000081.
What is meant by Scientific notation?Very big or very small numbers can be written using scientific notation. Once a number between 1 and 10 has been multiplied by a power of 10, it is then expressed in scientific notation.
Simple numerical writing is what scientific notation is. Because it is shorter and more efficient and indicates magnitude very easily, it is particularly helpful for expressing very large or very small values. Every real number can be expressed as the product of two parts: an integer power of ten and a decimal part.
Let the equation be [tex]$0.09 \cdot\left(9 \times 10^{-4}\right)$[/tex]
Apply exponent rule: [tex]$\quad a^{-b}=\frac{1}{a^b}$[/tex]
[tex]$=9 \times 0.09 \times \frac{1}{10^4}$$[/tex]
Multiply fractions: [tex]$\quad a \times \frac{b}{c}=\frac{a \times b}{c}$[/tex]
[tex]$=0.09 \times \frac{1 \times 9}{10^4}[/tex]
[tex]$& \frac{1 \times 9}{10^4}=\frac{9}{10000} \\[/tex]
simplifying the above equation, we get
= 0.09 × 9/10000
Multiply fractions: [tex]$\quad a \times \frac{b}{c}=\frac{a \times b}{c}$[/tex]
= 9 × 0.09/10000
= 0.81/10000
Divide the numbers: 0.81/10000 = 0.000081
= 0.000081
Therefore, the Scientific notation of [tex]$0.09 \cdot\left(9 \times 10^{-4}\right)$[/tex] be 0.000081.

The way the outlier affects the mean, median, and mode is:
It does not affect the mode It will increase the mean. It will not affect the medianWhat are the effects of outliers ?The outlier will increase the mean, as it will significantly increase the sum of the values. The presence of an outlier will not affect the median, as it only changes the position of the middle value.
The mode is the value that occurs most frequently in a data set. In this case, the mode will not be affected because the outlier is not the most frequent in the data set and only appears once.

In addition, he will receive Rs. 3,50,000 one year from today and Rs. 5,50,000 two years from today. He plans on saving all of this money and investing it for her retirement. If Parag can earn an average of 12% on her investments, how much will he have in his account if he retires 26 years from today (at t=26)?
Answer:
Parag will have Rs. 44,68,802 in his account if he retires 26 years from today. This can be calculated by using the formula A = P (1+r)n, where A is the future value of the investment, P is the present value, r is the interest rate, and n is the number of years until retirement. In this case, P = 10,50,000, r = 12%, and n = 26, so A = 10,50,000 (1+0.12)26 = Rs. 44,68,802.

What is average?In mathematics, the middle value—which is determined by dividing the sum of all the values by the total number of values—is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.
According to question:As you have calculated average students in a year is 53.So, we can say students are increasing by 53 each year.
4) in 2003, number of students are 1389 and in three year students increase by 53* 3 = 159
in 2000,
Students = 1389 - 159
= 1230
5) We have 1230 students in 2000, and students will increase by 53 each year.
So, for t years equation will be
Students = 1230 + 53t
6) There is 15 years to come 2015, using our equation;
Students = 1230 + 53t
Students = 1230 + 53(15)
Students = 1230 + 795
= 2025 students.

The statement that proves that there is a unique element x such that P(x) is true is: c) 3x(P(x) & Ay(P(y) --> x = y)).
What is probability?The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms.
Here,
In this statement, the quantifier "3x" says that for every element x, and the condition "P(x)" says that x satisfies a certain property. The statement "Ay(P(y) --> x = y)" says that for every other element y, if y also satisfies the property, then it must be equal to x. Hence, if there is a unique element x such that P(x) is true, then this statement is true.
Option (a) says that for every element y, P(y) is equivalent to y = x, but this statement alone does not imply that there is only one element that satisfies P(x).
Option (b) says that for every element x, if P(x) is true, then there is no other element y that also satisfies P(y) and is not equal to x. However, this statement alone does not imply that there exists an element x that satisfies P(x).

using the following data on the observations 10, 13, 4, and 20, confirm that the complete linkage distance between the cluster containing {10, 13} and the cluster containing {4, 20} is 2.577 units as displayed in the dendrogram.
According to the dendrogram, the complete linkage distance between the cluster containing {10, 13} and the cluster containing {4, 20} is 2.577 units.
A dendrogram is a type of diagram that is used to represent the structure of a set of objects, where the objects are linked together in a hierarchy.
Now, let's take a closer look at the dendrogram that displays the complete linkage distance between the cluster containing {10, 13} and the cluster containing {4, 20}.
In this case, the maximum distance is
=> 20 - 4 = 16 units.
Next, we need to normalize the distance by dividing it by the square root of the number of data points in the two clusters. In this case, there are 4 data points in total, so the normalized distance is
=> 16 / √4 = 4.
Finally, we can use the formula for the complete linkage distance, which is given by
D = √2 * (1 - x),
where x is the normalized distance. Plugging in our values, we get
D = √2 * (1 - 4) = √2 * -3 = -2.236 units.

the following are two points in a data set, find the euclidean distance between them. (1.0, 6.1) and (3.3, 8.7) round your answer to 1 decimal place.
The Euclidean distance between (1.0, 6.1) and (3.3, 8.7) is 3.48, rounded to 1 decimal place.
The Euclidean distance formula is used to calculate the distance between two points in a two-dimensional plane. The formula for Euclidean distance between two points (x1, y1) and (x2, y2) is given by:
[tex]d = √(x2-x1)2 + (y2-y1)2[/tex]
For our two points, (1.0, 6.1) and (3.3, 8.7), the Euclidean distance is:
[tex]d = √(3.3-1.0)2 + (8.7-6.1)2 \\ = √(2.3)2 + (2.6)2 \\ = √5.29 + 6.76 \\ = √12.05 \\ = 3.48[/tex]

What exactly is a matrix?A collection of integers organised in rows and columns to form a rectangular array. The numbers are referred to as matrix elements or entries. Matrices are widely used in engineering, physics, economics, and statistics, as well as in many disciplines of mathematics. Matrices have also found usage in computer graphics, where they have been utilised to represent picture rotations and other transformations.
If there are m rows and n columns, the matrix is said to be an “m by n” matrix, written “m × n.” For example,
[tex]\left[\begin{array}{ccc}1&2&3\\4&5&6\end{array}\right][/tex] its a 2×3 matrix.
The proof of the theorem proves that the columns, say, A and B must be independent.
In the matrix, there is linearity and the trivial solution would be [ 0, 0 , 0 , 0] for the matrix to exist. In other words, all the unknowns must be zero.
This establishes the fact that the matrix T needs to be independent for the matrix function, say T (x) to be one-to-one.
By definition, one-to-one is ker (T) = {0}
Thus, the null space is occupied only by the zero vector.
Note: if there was no linear independence in the vectors, the solution would not be zero in the vector.

You want a system of equations and their solution for the number of shots of each type if the total number is 52 and the points from 1- and 2-point shots total 89.
SetupLet x and y represent the numbers of 1- and 2-point shots, respectively. The problem description tells of two relations:
x + y = 52 . . . . . . . total of shots is 52
x + 2y = 89 . . . . . . total of points is 89
SolutionSubtracting the first equation from the second, we get ...
(x +2y) -(x +y) - (89) -(52)
y = 37
Then the first equation tells us ...
x = 52 -y = 52 -37 = 15
The team made 15 1-point shots and 37 2-point shots.
