The measurement deviates from the mean by more than 100 standard deviations.
What does simple math standard deviation mean?It's a way to gauge how widely apart each data point is from the mean. The standard deviation formula comes in two different forms: Standard deviation for the population When you can measure the entire population or the entire collection of data, you use the population version of the formula. Experts in statistics have determined that measurements that fall within a 2 SD range of the true value are more accurate than those that do not..

If QR = 6x, RS = 10, and QS = 5x + 13, what is QS?
If QR = 6x, RS = 10 and QS = 5x+13, then the length of the line QS is 28 units.
The length of the line QR = 6x
The length of the line RS = 10
The length of the line QS = 5x+13
We know
The length of the line QS = The length of the line QR + The length of the line RS
Substitute the values in the equation
5x+13 = 6x + 10
Move the 6x to the left hand side of the equation and move 13 to the right hand side of the equation
5x-6x = 10-13
Subtract the terms
(5-6)x = 10-13
-1x = -3
x = 3
Then the length of the QS = 5x+13
Substitute the value of x in the equation
The length of the line QS = 5×3+13
= 15+13
= 28 units
Hence, if QR = 6x, RS = 10 and QS = 5x+13, then the length of the line QS is 28 units

What is the Angle Sum Property?According to the triangle's "angle sum property," a triangle's three inner angles can never add up to more than 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180°, regardless of whether it is acute, obtuse, or right.Given angles are:
A = (3x+8)°
B= (6x-2)°
C = 69°
Using the Angle sum property we get,
(3x+8)° + (6x-2)° + 69° = 180°
9x + 75° = 180°
9x = 180°- 75°
x = 11.7

What is proportional relationship?Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. The relationship between two quantities is constant for all values when they are proportional, which indicates that as one quantity rises, the other rises as well. An illustration would be the ratio of a circle's circumference to its diameter, which is equal to pi.

The ratio of men to women working for a company is 4 to 7. If there is 253 employees total, how many men work at the company
Answer:
92 men
Step-by-step explanation:
First, since they give you the total employees, you need to add the ratios together to get a total.
4 + 7 = 11
Next, setup a proportion using men to total employees.
[tex]\frac{4}{11}=\frac{m}{253}[/tex]
The left side is the ratio and the right side is the actual. m will represent the total number of men employed.
Cross multiply then divide.
4 x 253 = 1012
11 x m = 11m
11m = 1012
11m/11 = 1012/11
m = 92

During 712months of hibernation, a black bear experienced a weight loss of 64.5 pounds.
On average, what was the bear’s weight change per month?
On average, the bear's weight change per month was 8.6 pounds.
What is the average?The average is the mean value in a data set.
We compute the average by adding the data values and dividing by the number of items in the data set.
In this scenario, the average weight loss per month offers an idea of the weight change the bear experienced during the 7¹/₂ months.
The number of months during hibernation = 7¹/₂ or 7.5 months
The total weight loss = 64.5 pounds
The average weight change per month = 8.6 pounds (64.5/7.5)
Thus, we can conclude that, on average, the bear experienced a weight loss of 8.6 pounds per month and reduced by a total of 64.5 pounds in 7¹/₂ months.

From the figure shown below , we can see that
∠AOE and ∠BOD are vertically opposite angles ,
the property of vertically opposite angle states that " the vertically opposite angles are equal in measure ."
So,
substituting the values of ∠AOE and ∠BOD from the figure , we get

What is meant by angles?An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The two rays are called the sides of an angle, and the common endpoint is called the vertex.
If CA and CE are opposite rays, CH bisects ∠ GCD, and GC bisects ∠ BGD.
Given: m ∠ BGC = (7x - 2)° and m ∠ CGF = (8x - 8)°,
m ∠ BGC = m ∠ CGF
7x - 8 = 8x - 8
substracting 2 from both sides of the equation, we get
7x - 8 = 8x - 8 - 8
7x - 8 = 8x
simplifying the above equation, we get
x = 6
Therefore, the value of x = 6.

What is an expression?An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
In order to solve this word problem, we would assign a variable to the age of this person and then translate the word problem into algebraic equation as follows:
Let x represent the age.
Translating the word problem into an algebraic equation, we have;
x + 65 = 6(x - 10)
Opening the bracket, we have:
x + 65 = 6x - 60
Re-arranging the equation, we have:
6x - x = 60 + 65
5x = 125
Dividing both sides by 5, we have:
