Today I am going to teach about the components of a bar graph and why they are useful to use in our everyday lives.
First, I would like everyone to copy the information I have up on the board and take out a piece of graphing paper.
*On Board*
Song # of Students who like the Song
"Drunk in Love" 7
"Energy" 13
"Blurred Lines" 4
Once this table has been copied, I want every to draw a large "L" on their graph paper. The horizontal line will be labeled our "X" and our vertical line will be labeled "Y". The "X" axis is considered our constant value within our data. The constant in this case would be which song each person likes. Our "Y" axis will be our independent variables. In this case, the number of people who like each song.
Now because we know our axis' we are going to label the "X" axis with the names of the three songs and title it "Song".
Next, we're going to label our "Y" axis every other line up to 15 with the proper title.
Our final step is to fill in the graph. Use about two boxes worth to make your bar graph thick enough to tell. You will follow "Drunk in Love" up to the line 7 is labeled. And so fourth with the other two. Once complete, title your graph so the whole chart is complete and the data is clear!

Today I am going to be teaching everyone about combinations.
A combination is a way of selecting several things out of a larger group, where order doesn't matter.
The key thing to remember with combinations is that order DOESN'T matter.
The combination general formula is the number of distinct combinations of "r" items selected (without replacement) from a pool of "n" items, denoted by nCr
The n and r in the formula stand for the total number of objects to choose from and the number of objects in the arrangement.
A combination of items occurs when:
* the items are selected from the same group
*No item is used more than once
*The order of items makes no difference

Combination problems involve situations in which the order of items makes no
difference.
An example to help further explain the combinations formula:
- How many ways can a group of three students be selected from a class of 21 students?
to answer this we would apply the formula:

Linear Growth
Linear Growth can be shown as a graph with a straight line. The reason that this line is straight is because the slope, M, remains constant. To calculate the slope of a line, one takes two different coordinate sets (y1,x1) (y2, x2) then subtracts them like so: (y2-y1)/(x2-x1)=m
sample set: (2,3) & (5,2) :: (5-2)/(2-3) = -3
since the slope is negative, the line will slope downward
after finding the slope, the y intercept, b, becomes the next thing to look for.
equation for linear function: y=mx+b
pick a set that sets x to 0
sample from set above: (0,7)
7=-3(0)+b
7=b
after finding the intercept and slope, you can create a linear function:
sample: y=-3x+7

1. butter causes high cholesterol
2. “I cant believe its not butter” allows you to enjoy the taste of butter without causing high
cholesterol
conclusion: if you want the taste of butter but not get higher cholesterol then you should buy
‘i cant believe its not butter’
3.
4.
this argument is valid and true making the argument sound. the premises guarantee the truth
of the conclusion and according to the ‘I cant believe its not butter’ website “I cant believe its
not butter” has less fat and than real butter but tastes just like real butter.
5.
P:If butter causes higher cholesterol then
Q: you should buy “i cant believe its not butter” so you can enjoy the taste of butter without
getting higher cholesterol
6.
a. The argument is not a tautology but if the premises are true in real life then
the argument does make sense.
b. Truth tables show very clearly premises guarantee all possible truths of the
conclusion.
8. the argument is not a fallacy
9. This experiment did help but I wish i picked a different argument.

Hello my name is Professor Liam. Today I will be teaching you about the math concept, combinations. The definition of combinations is, a joining or merging of different parts or qualities in which the component elements are individually distinct. So an example of this would be a license plate. To see how many combinations you can possibly have on your license plate you would multiply the amount of possible outcomes each letter or number can be. My car is registered under California so I will use that as an example. A California license plate has 7 letters and numbers. It starts out with one number then continues with 3 letters then has 3 other numbers. So to figure out how many combinations I can possibly have for a California license plate I would multiply 10, because I can have 10 possible numbers in the first place, by 26, because of 26 letters in the alphabet, by 26, by 26, by 10, by 10, by 10. The equation would look like this:
10*26*26*26*10*10*10
This gives an answer of 175,760,000 possible combinations for a California license plate.
If license plate could not have repeating numbers and letters than I would have the equation 10 times 26 times 25, because I couldn't use the previous letter, times 24, because I couldn't use both the previous letters, time 9, because I couldn't use the number in the first space, times 8, times 7. This process is called combination without replacement because you are not placing the previous letter or number back into the possible numbers or letter that could be chosen for the next letter or number. The equation for a license plate without replacement would be:
10*26*25*24*9*8*7
This gives an answer of 78,624,000 possible combination for a California license plate without combination.
Thank you for coming to class.

Summary:
Whats up students, I’m professor Jon and I’m going to teach
you all about exponentials growth. Growth is the accumulation of a given unit
so when we consider exponential growth: it takes on a new meaning. Exponential
growth whose rate becomes larger in proportion to the growing total number/
unit/ or size. An example of exponential
growth in the real world is population growth. If your parents were the first
parents of this generation and they
had you and another sibling, and then you and your other sibling both had two
more children, this would be an example of exponential growth because the
number of children is increasing in multiples, not linearly.
How to learn exponential growth:
Take a given number. Lets use 2. You can increase our friend
number 2 by adding exponents to the number. If we add an exponent of 3 to our
good friend 2 it will look like this : 2^3. All this means is you take our friend two and multiply
it by itself three times giving you an answer : 2 x 2 x 2 = 8 so 2^3 = 8.
You can tell if a series of numbers or a graph is
exponential if it shows the same quality as above. For example, if you were
graphing a series of number that looked like this
2
|
8
|
8
|
512
|
512
|
13,369,344
|
You would be able to tell that the numbers are growing
exponentially three times for every new product made because the numbers are
not increasing the same amount every time, the rate of increase is growing

mean, median, mode
1,2,4,6,8,10,10,12
to find the mean for this set of data, first add up all the numbers
1+2+4+6+8+10+10+12=53
next, divide the sum by the amount of data points and quotient is the mean of the data
53/8=6.625 --> mean
to find the median of the data, first write the data points in increasing order
1, 2, 4, 6, 8, 10, 10, 12
next find the middle value
there are eight data points so the median will be the average of the middle two values (6, 8)
so the median of this data is 7
to find the mode, simply locate the value that occurs the most, so in this case, the mode is 10.
