The sum of squares of two sides of a triangle is equal to another side of a triangle is called the Pythagorean theorem.
It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
c^2=a^2+b^2--------(1)
Where a,b, and c are sides of a triangle.
To measure the length of the missing side in a right triangle using the Pythagorean theorem:
c^2=a^2+b^2
By using this formula we can find the length of a missing side.
To understand more we have to solve an example:
let A, B, and C are points of a triangle AB, BC, and CA are the sides of the triangle.
Consider BC=3cm CA=4cm AB=?
Use equation(1) to find the length of AB
AB^2=BC^2+CA^2
AB^2=3^2+4^2
AB^2=9+16=25
AB=5cm

what does your work show about the behavior of the standard deviation of a binomial distribution as the probability of a success gets closer to zero?
The probability of a success gets closer to zero is 15.
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?

Given ,
Mean deviation (MD) =12
Here is the inequality to calculate the standard deviation.

Step-by-step explanation:
11. Natalee wanted to write a function which shows a 40% increase in bacteria growth.
There were 100 bacteria to start. She wrote y = 100 (40)* but she felt that she was
wrong because her y-values were extremely high when she graphed it. Identify Natalee's
mistake, and write the actual function for this scenario.
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.

In the given sample mean, there are total 5 elements present.
What is a sample mean?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.

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

Eve knits scarves for her online store. This week she has already knitted 9 scarves. There are 2 days left in the work week. She set a goal for herself to knit at least 15 scarves and at the most 19 scarves this week. Eve wants to know how many scarves she should knit each day to meet her goal.
Which inequality represents the given situation?
• A. 15 ≤ 2x - 9 _> 19
• B. 15 ≤ 2x - 9 ≤ 19
• C. 15 ≤ 2x + 9 ≤ 19
• D. 15 _>2x+9 _>19
Answer: C. 15 ≤ 2x + 9 ≤ 19
Step-by-step explanation:
We know that her goal is to knit at least 12 scarves and, at the most, 19 scarves
So it has to be bigger or equal to 15 and smaller or equal to 19, so it can't be A or D.
We also know that she has already knitted 9, so our equation has to have a +9
So the answer is C. 15 ≤ 2x + 9 ≤ 19

The annual earnings for Walker will be $53223.
How to calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.
In this case, Ciara Walker was earning $47,100 and received a 13% raise.

Arthrogryposis, also called arthrogryposis multiplex congenita (AMC), is a term used to describe a variety of conditions involving multiple joint contractures (or stiffness).
Arthrogryposis is a general or descriptive term for the development of non progressive contractures affecting one or more areas of the body prior to birth (congenitally). A contracture is a condition in which the joint becomes permanently fixed in a bent (flexed) or straightened (extended) position, completely or partially restricting the movement of the affected joint. When congenital contractures occur only in one body area which means it is not referred to as arthrogryposis but rather as an isolated congenital contracture. The most common form of an isolated congenital contracture is clubfoot. When arthrogryposis affects two or more different areas in the body, it may be referred to as arthrogryposis multiplex congenita (AMC).

a square has an area of 121 feet square feet. what is the length of each side
Answer: 11 feet
Step-by-step explanation:
The equation for area of square is
area = s^2
So we just need to take the square root of 121, and we will get the answer is 11 ft!
Answer:
11 ft
Step-by-step explanation:
Since the area of the square is 121 (and squares have all four sides the same length), the sides must be 11 feet. Because
11 × 11 = 121
You could show work by using an equation.
Area = s^2
121 = s^2
Square root both sides.
sqrt121 = sqrt(s^2)
11 = s
The side length is 11 feet.

How to determine the median of the density curveFrom 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
