The outlier of the data is 14.16 gram
What is Outlier?An outlier is a data point in statistics that dramatically deviates from other observations. An outlier may reflect measurement variability or it may point to an experimental error; the latter is occasionally removed from the data set. In statistical analyses, an outlier can result in significant issues.
Given:
Weights of the samples are 13 g, 14 g, 23 g, 11 g, 15 g, 14 g, 14 g, 12 g, 13 g, 15 g, 14 g, and 12 g.
So, the outlier is
= 13 x 2 + 14 x 4 + 12 x 2 + 11 + 15 x 2+ 13 / 12
= 170 gram /12
= 14.16 gram.
Hence, the outlier of the data is 14.16 gram

The figure shows right triangle MPR on the coordinate plane. Line segment MQ is
a median of the triangle.
What are the coordinates of point Q? Explain your answer. Using the information in the figure, show that the length of the median MQ is half the length of the hypotenuse of MRP. Provide an argument supported by valid mathematical
reasoning and/or calculations.
Answer:
see explanation
Step-by-step explanation:
the median is a segment that goes from the vertex of a triangle to the midpoint of the opposite side.
Then Q is the midpoint of PR
given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint M is
M = ( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ) ← midpoint formula
use this formula to find the coordinates of Q
with (x₁, y₁ ) = R (0, 2b ) and (x₂, y₂ ) = P (2a, 0 )
Q = ( [tex]\frac{0+2a}{2}[/tex] , [tex]\frac{2b+0}{2}[/tex] ) = ( [tex]\frac{2a}{2}[/tex] , [tex]\frac{2b}{2}[/tex] ) = (a, b )
---------------------------------------------------
use the distance formula to find the lengths of median MQ and hypotenuse PR of Δ MRP
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = M (0, 0 ) and (x₂, y₂ ) = Q (a, b )
MQ = [tex]\sqrt{(a-0)^2+(b-0)^2}[/tex] = [tex]\sqrt{a^2+b^2}[/tex]
repeat with (x₁, y₁ ) = P (2a, 0 ) and (x₂, y₂ ) = R (0, 2b )
PR = [tex]\sqrt{(0-2a)^2+(2b-0)^2}[/tex]
= [tex]\sqrt{(-2a)^2+(2b)^2}[/tex]
= [tex]\sqrt{4a^2+4b^2}[/tex]
= [tex]\sqrt{4(a^2+b^2)}[/tex]
= 2[tex]\sqrt{a^2+b^2}[/tex]
then MQ is half PR

A company hired 20 new graduates. The mean salary of the newly hired employees is 38 in thousands of dollars, where Σ(x - 38)² = 64. Which is the population variance of the given data ?
The population variance of the given data is 3.2.
Given Σ(x - 38)² = 64 .
We know that the population variance of the data is the square of the standard deviation.
Now the standard deviation for the population is given by
σ =√(Σ(x - 38)² / N)
Again variance = σ ²
Let us first calculate σ .
σ = √(64/20) = √3.2
variance
= σ ²
= (√3.2)²
= 3.2
Therefore the variance of the population is 3.2
In probability theory and statistics, variance is the predicted squared variation of a random variable from its population mean or sample mean. Dispersion, or how far apart from the mean a set of data are from one another, is measured by variance.
A few ideas that use variance include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and Monte Carlo sampling.

What is identity and contradiction?
An identity is an equation that can be solved using any integer that can replace the variable in the equation in a meaningful way. A conditional equation is one that is met by some numbers but not by others, such as 2x = 4. A contradiction is an equation, such as x = x + 1, that cannot be solved.
We know that,
An equation having infinitely many solutions is called an identity equation.
An equation that having no solution is called a contradiction.

Combining like terms
x = 30
Therefore, The value of x is equal to 30 and the equation has one solution and it is neither identity nor contradiction.
(ii) 25 - 4x = 15 - 3x +10 - x
Combining like terms
0 = 0
It means, The equation is true for all values of x.
Therefore, This equation has infinite number of solutions and it is an identity.

since the exterior angles are also congruent, we can extend lines BC and AD as you see there in green and run an exterior angle at vertices A and C, since those two exterior angles are congruent and are also alternate interior ones, voila! it must be that BC || AD.

Two identical rectangles linked at one corner are drawn on coordinate axes. Give the coordinates of point A and point B
The coordinates of the vertices of the points A and B are;
A(9, 7), B(15, 9)
What is the location of a point on the coordinate plane?A point on the coordinate plane is described by a pair of points known as an ordered pair.
The coordinates of the vertices of the identical rectangles are; (3, 5), (9, 5), (9, 9)
The length of (9 5) from A is the same as the length from (9, 9) to A.
The coordinate of the point A is therefore;
x-coordinate = 9
y-coordinate = 5 + (9 - 5)/2 = 7
The coordinate of point A is (9, 7)
The length of the sides of the rectangle are;
Length = 9 - 3 = 6
Width = 9 - 7 = 2
The coordinates of the point B are;
x-coordinate = 9 + 6 = 15
y-coordinate = 9

Answer:
$382.20 ≤ t ≤ $764.40
Step-by-step explanation:
Hello, so first we would need to convert bi-weekly pay to monthly income.
First we would times $1,764.00 by 26
1764.00 × 26 = 45864
Then we would divide 45864 by 12
45864 ÷ 12 = 3822.
Then we calculate how much the worker can spend if their monthly budget for food is in between 10% and 20%
3822 × 10% = 382.20
3822 × 20% = 764.40
So, we can see the correct answer is $382.20 ≤ t ≤ $764.40.

The sinusoidal equation for the graph in terms of Y, the temperature in degrees Celsius) and the time, T in hours is; Y = 3·sin((π/12)·(T + 6)) + 15
What is a sinusoidal equation?A sinusoidal equation or function is an oscillating and periodic function that is based on the sine of an angle.
The required form of the response is y = a·sin(b·(t - h)) + kThe function of the graph is a sinusoidal function with the parts;
a = The amplitude
b = The frequency = 1/T
T = The period of the function
k = The vertical shift of the function
h = The horizontal shift of the function
From the graph, we have;
The minimum point on the graph of the function = (1, 12)
The maximum point on the graph of the function = (13, 18)
The amplitude of the graph a is therefore; a = (18 - 12)÷2 = 3
The period of the graph = 1/b
1 cycle is completed in 24 hours, which indicates that the frequency of the function is; f = 2·π/24 = π/12 = b
The vertical shift, k from the parent function, y = sin(x) which is the distance the midline of the graph is raised above the x-axis is; k = 15
sin((π/12)·(0 - h)) = -1
((π/12)·(0 - h)) = -π/2
-h = 6
h = -6
The function, y = a·sin(b·(t - h)) + k, is therefore;
