the mean of 2,10,9 is what
Answer:
7.
Step-by-step explanation:
Mean = (2+10+9)/3
= 21/3
= 7.
Answer:
the mean is 7
Brief explanation:
To find the Mean of a set we add all the numbers first.
Remember that the Mean relies on a sum.
So we just add up 2 + 10 + 9 = 21
Then divide 21 by 3 (3 because there are 3 numbers in this set) :
21 : 3 = 7
so how do we find the Mean?We take all the numbers in the set, and divide by how many numbers we have in this set.

1+1+1-5+2+2+2+4-8 x 100 +1
Answer:
-792
Step-by-step explanation:
According to PEMDAS, you would multiply 8 x 100 first making the equation
1+1+1-5+2+2+2+4-800+1
then combine like terms, 8-800+1
Since 8 is smaller than 800, you would get a negative number, -792
then you add 1, making your answer -792
560/17 participate in a football tournament if each team plays against every other team ones, how many matches will be played tota
According to the information, it can be inferred that the total matches that would be played in total are 160,461.
What is a mathematical combination?A combination is a term to refer to an arrangement of elements in no particular order. For example:
When we put together a sandwich with salami, ham and turkey. The order in which the deli meats are placed does not matter as long as they are in a sandwich. There is only one way to stack the meat on the sandwich when the order doesn't matter.
How to calculate how many matches will be played in total?To calculate how many matches will be played in total we have to perform the following procedure:
[tex]= ^{567} C_{2} \\= \frac{(567)!}{2!565!} \\= \frac{567 * 566 * (565)!}{2 * (565)!} \\= 567 * 283\\= 160,461\\\\[/tex]
As we can see after the combination, the number of games that would be played in this tournament would be 160,461.

a) For each matrix, describe the transformation that is
achieved.
b)
A further transformation matrix D is required which combines
the effects of matrices A and B. Explain why care must be
taken in the ordering of transformation matrices.
This could result in an unexpected transformation. Therefore, the order of the matrices must be taken into account when combining them.
What is matrix?Matrix is a mathematical entity composed of elements arranged in rows and columns. It is used to represent and manipulate various types of data and is commonly used in scientific and engineering applications. Matrices are useful for representing linear equations and transformations of vector spaces, such as scaling and rotation. They can also be used to store data and perform calculations on that data.
Matrix A is a scaling matrix which is used to change the size of an object. This transformation is achieved by multiplying each component of the vector by a value, resulting in a larger or smaller object.
Matrix B is a rotation matrix which is used to rotate an object. This transformation is achieved by multiplying each component of the vector by a coefficient which is then added to the other components, resulting in a rotated object.
Matrix D is a combination of matrices A and B, where the effects of matrix A are applied first and then the effects of matrix B are applied. Care must be taken when combining the two matrices because the order of the transformations matters; applying the effects of matrix B first would result in a different transformation than applying the effects of matrix A first. If matrix B is applied first, it will rotate the object before it is scaled, meaning that the scaling will be applied to the already-rotated object. This could result in an unexpected transformation. Therefore, the order of the matrices must be taken into account when combining them.

If the social security tax is 6.2% and the Medicare tax is 1.45% and Murr annual salary is 57,285.50 then what is murrs annual social security deduction
Answer: Murr's annual social security deduction is the amount of money he pays in social security taxes. Social security tax is 6.2% of Murr's annual salary. To find the annual social security deduction, we can multiply Murr's annual salary by the social security tax rate:
57,285.50 x 6.2% = 3,541.829
Murr's annual social security deduction is 3,541.829
Note that Medicare tax is 1.45% and it's calculated separately, if you want to calculate it you can use the same formula:
57,285.50 x 1.45% = 829.4078
So the total Social security and Medicare tax is 3,541.829 + 829.4078 = 4,371.2368
It's important to note that these are the federal Social Security and Medicare taxes, there might be additional state taxes or deductions that are not included.

Answer:
a = 6 , b = 17
Step-by-step explanation:
using Pythagoras' identity.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
using right triangle ABD , then
a² + 8² = 10²
a² + 64 = 100 ( subtract 64 from both sides )
a² = 36 ( take square root of both sides )
a = [tex]\sqrt{36}[/tex] = 6
using right triangle ABC
note that BC = a + 9 = 6 + 9 = 15
b² = 8² + 15² = 64 + 225 = 289 ( take square root of both sides )
b = [tex]\sqrt{289}[/tex] = 17

On the unit circle, how many radians would the point (-1,0) pass if rotated counterclockwise until it first reaches (root3/2,-1/2)?
The radians that the point (-1,0) would pass if rotated counterclockwise until it first reaches (√3/2,-1/2) is 2π/3.
How do we get the radians?When a point on the unit circle is rotated counterclockwise, it traces out an angle in radians. To find the number of radians that the point (-1,0) would pass if rotated counterclockwise until it first reaches (√3/2,-1/2), we can use the fact that the point (-1,0) corresponds to an angle of π radians on the unit circle, and the point (√3/2,-1/2) corresponds to an angle of 5π/3 radians on the unit circle.
To find the number of radians passed, we need to subtract the initial angle (π) from the final angle (5π/3), so (5π/3 - π) = 2π/3 radians.
Therefore, the point (-1,0) will pass 2π/3 radians when it is rotated counterclockwise until it first reaches (√3/2,-1/2)

(a) A basis for a subspace is a set of linearly independent vectors that span the subspace. To find a basis for this subspace, we can use the following steps:
Write the given set of vectors as the rows of a matrix, with each vector as a row.
Use row-reduction (Gaussian elimination) to put the matrix in row-echelon form.
The non-zero rows of the row-echelon form matrix form a basis for the subspace.
So, we get the matrix:
| 6a - 2c | -5b - 5c | -6a + 5b + 2c | -6a + 2c |
Using row-reduction, we can simplify the matrix to:
| 1 - 1/3 | 0 | 1/3 | -1/3 |
The non-zero rows are {[ 1 - 1/3 0 1/3 -1/3 ]}
So, a basis for the subspace is:
{[ 1 - 1/3 0 1/3 -1/3 ]}

First man travels 1 sec + 2 sec = 3 sec

Second man travels 2 sec
d = (1/2)(9.81 m/s²)(2 s)² = 19.62 m
Distance between the 2 men:
