- SOLVING MATH PROBLEMS WITH LEVIBy: Justin GerardoMr DuarteJanuary 21 2022
- Hello my name is Levi!
- Welcome to Toronto!Today you are going to follow me on my adventure to work, but in order to do so we need to do a lot of MATHHH!!
- hmmm? that's odd, the door is locked.
- Ahaaa I know just the trick, a math problem
- COMBINATIONS:There are 7 different candies and you are only able to choose 2. how many different ways can you chose 2 pieces of candy.
- 7!/(7-2)2! = 7!/5!2!5040/240= 21
- Therefore you have 21 different ways you can choose two pieces of candy
- A) 8! / (8-5)!=8! / 3! =(8)(7)(6)(5)(4)(3) / 3!=10,080
- PERMUTATIONS:Now we are on to the next question to move on, Q) what is 8p5
- STATE WETHER THE EVENTS ARE DEPENDANT OR INDEPENDENT:1. Having your power bill payed on time and having your power cut.2. landing on heads when flipping a coin and rolling a pair of dice3. passing the road test and fixing your tires.
- Hmm? I'm pretty sure the first one is dependant and the other two are independent.
- sheesh, I'm finally done with that.Lets check up on Gerald and see if he needs help with anything.
- Whats up Gerald!!
- About time, I was expecting you to visit, I've been really stuck on this problem. Care to help me out
- For sure let me take look at it.
- wow thank you so much Levi, you should always do my work!
- PROBABILITY: What is the probability of Levi eating his favourite cheeseburger and listening to his favourite song on the radio. if the probability of him eating a cheeseburger is 0.35 and the probability of him listening to his favourite dong is 0.20
- OH I GOT IT! So for this question you just need to multiply it so in that case you just multiply (0.35)(0.20) which will give you 0.07
- okay, now that I'm done helping Gerald I really gotta make my way to work before I'm late
- FINALLY, I'M HERE, but we have to go through different questions in order to get to my office and to get through them we need to solve some math problems.
- p=70=0.70q=30=0.30E(x)= q/p = 0.30/0.70=0.43
- GEOMETRIC DISTRIBUTUIONIn Basketball, Sampath has a 30% chance of making free throws. what is the expected waiting time before he misses a free throw.
- alright, last question before I go up
- p(x) 15Cx X 9C4-x/24C4
- HYPERGEOMETRIC DISTRIBUTIONDetermine the probability distribution for the number of shoes on a 4 story rack from 9 slippers and 15 shoes.
- I am very close to my office, couple more questions to go!
- OH man more questions
- (100)(30000)/500=600this means about 600 cars are broken out of the 30,000.
- INDICIES:Q) there was a sample made with 500 cars from 30,000. 100 are found broken. calculate how many are broken out of the 30,000
- MULTIPLICITIVE PRINCIPLE: Q) you are deciding what to wear to go to a party. You have 3 shirts, 5 shorts, 6 pants, 4 socks and 2 pair of shoes, how many outfits can you make with these clothing items.
- Hmmm??? oh I finally got it. what you need to do is multiply all the items you have together to see how many outfits you can make. in this case do (3)(5)(6)(4)(2)=720you can make 720 outfits
- finally, we're in front of my office but to get in I need to solve a question.
- now that I am in my office, one more question and we're done for the day.
- DATA ANALYSIS: analyze the graph and tell me the base year and base valueQ1)What is the base year?Q2)What is the base value??
- A1) The base year was 2011A2) The base value was 25 in 2011
- DATA ANALYSIS: Q1)What is the base year?Q2)What is the base value??
- YESSS!!! we completed all the questions. I hope you enjoyed the adventure and thank you for coming along.
