Simple probability is the ratio/fraction of the number of outcomes favorable for the event to the total number of possible outcomes. In other words, a measure of the likelihood an event will occur.

Mean Absolute Deviation (MAD) | Math with Mr. J

Make histograms by making groups of all the numbers! Make groups by 10s as in 0-10, 10-20, 20-30, 30-40. But when its up to the number you don't add the maximum number in the group as in you don't add 10 in the first group. After you made your groups you count how many numbers are in each group and you color it on the graph!

Example:  a kid has a bowl of candies 3 are lemon flavored and 5 are orange flavored. so the ratio of lemon flavored candies to orange flavored candies is 3:5

Ratios can be written in three ways ( 3 to 5 |  3:5 |  3/5 )

Equivalent proportions are proportions that are the same although they look a little different.

Exmaples: (1/2 | 2/4 | 3/6) or (2/3 | 4/6)

Rational number is usually expressed in Q. These numbers are subsets of real numbers, which include complete number lines and are usually represented by R. - Jacky

To get MAD, you’ll have to get the mean first. After you’ve got the mean, you have to subtract the mean with all the numbers from the number group. Then add the answers you’ve got. After, divide the answer with the same number you divided the mean with.

Make a Box and whiskers plot by drawing dots or lines on where each number is on the line plot. Start from the minimum value and draw a line until Q1. After draw dots for median and Q3 and join a line. After outline the Q1-Q3 to a box. Last draw a line from Q3 to the maximum value!!!

How to Determine if Two Ratios Form a Proportion Using Equivalent Fractions | Math with Mr. J

# data[].attributes.body
The formula of the rate of change is k = y/x . This is used to determine the rate of change. What is "k = y/x"? First, it can be named as y = kx too. K is the constant of variation in probability constant. X and Y are two variables.

# data[].attributes.body
Mean: The mean is known as the average. You add all the numbers from the group of numbers. Then divide the answer with the amount of number you’ve added.

Median: The median is the middle number of a group of numbers. You firstly order all the numbers from least to greatest. Then take the middle number as the median. If there’s 2 middle numbers, you add those 2 numbers together and divide it by 2

The letter "k" in the equation y = kx represents the constant of proportionality. It is a numerical value that remains the same throughout a proportional relationship. The constant of proportionality determines the exact ratio between the values of the variables.

Finding a Percentage: These questions involve calculating a certain percentage of a given number. For example, "What is 20% of 150?"

# data[].attributes.body
Finding the Percentage Change: These questions involve calculating the percentage increase or decrease between two values. For example, "If the price of a product increased from $50 to $60, what is the percentage increase?"

# data[].attributes.body
Percentage Increase/Decrease: In these questions, you need to find the new value after a certain percentage increase or decrease. For example, "If a salary is increased by 10%, what is the new salary?"

# data[].attributes.body
Discount and Sale Price: These questions involve finding the sale price of an item after a given percentage discount. For example, "If a shirt is discounted by 20%, and the original price is $50, what is the sale price?"

Compound Interest: These questions involve calculating the growth of an investment over time, taking into account the initial amount, interest rate, and compounding period. For example, "If $1,000 is invested at an annual interest rate of 5% compounded annually, what is the value after 5 years?"

In math, percents is a way to express a part of a whole as a percentage. To calculate a percentage, you divide the number of a part by the whole and multiply it by 100. For example, if you want to find out what percentage of a cake you ate, you would divide the number of pieces of cake you ate by the total number of pieces and multiply it by 100. The result would be the percentage of the cake that you ate. Percentages are a useful way to represent information and are commonly used in everyday life, from calculating discounts to evaluating performance.

# data[].attributes.body
So the main point of understanding and solving percentages is that you need to calculation formula: (part/whole) x 100.

Rational number is any number that can be written as a fraction. The numerator (top number) and denominator (bottom number) are integers, and the denominator is not equal to zero. In other words, rational number can be expressed as p/q, where p and q are integers, and q ≠ 0. - Jacky

Mode: When finding mode, you look at a group of numbers and find which number has occurred the most. That is the mode.

Range: Range is where you order the group of numbers from least to greatest. Then subtract the greatest number with the least number.
