Math Question Help!!!?
a) The student is picking one class from each area, so you just multiply the number of classes in each area: 2 * 3 * 2 * 2 * 1. If these are all your classes to choose from: History 1 Science 1 Philosophy 1 Math 1 English 1 History 2 Science 2 Philosophy 2 Math 2 ............... Science 3 And you start listing out all the possible combinations of picking one item from each area, you can see how many possible selections there are: History 1 - Science 1 - Philosophy 1 - Math 1 - English 1 History 1 - Science 2 - Philosophy 1 - Math 1 - English 1 History 1 - Science 3 - Philosophy 1 - Math 1 - English 1 History 2 - Science 1 - Philosophy 1 - Math 1 - English 1 History 2 - Science 2 - Philosophy 1 - Math 1 - English 1 History 2 - Science 3 - Philosophy 1 - Math 1 - English 1 History 1 - Science 1 - Philosophy 2 - Math 1 - English 1 History 2 - Science 2 - Philosophy 2 - Math 1 - English 1 History 1 - Science 3 - Philosophy 2 - Math 1 - English 1 etc etc etc... b) The student is only picking one class out of ALL the areas, so you add up the total number of classes: 2 + 3 + 2 + 2 + 1 History 1 Science 1 Philosophy 1 Math 1 English 1 History 2 Science 2 Philosophy 1 Math 1 ............... Science 3
SAT MAth question ?
Alright so you know that there are 30 books but you do know if they are all history, you only know that they are books. So 23 of the books are history. p are hard cover books and x is hard cover history books. The trick is to read the question carefully because hard cover history books are different from just hard cover books. So hardcover books ( p ) minus the leftover amount of books ( 7 ) will be the amount of hard cover history books
Probability math history question?
scenario payoff probability HHH....... 8........1/8 HHT........4.........1/8 HTH........4.........1/8 THH........4.........1/8 HTT........2..........1/8 THT........2..........1/8 TTH........2..........1/8 TTT........1...........1/8 E(x) = sum payoff * probability +8/8 + 4*3/8 + 2*3/8 + 1/8 = 27/8 Coin flipping follows a binomial distribuion. The probability of getting n head in m tries with a fair coin... P(n out of m) = (1/2)^m * combin(m,n)
How many questions can you get wrong on SAT US history 2 and still score an 800?
You can get around 5 wrong answers and leave 2 blank answers. This varies for each test, but the leniency is around the same each year.That being said, if you are interested in applying to a top school and getting personal advice from me, a friend and I are running a site where we give feedback for students at Applihood.com
A student is taking two courses, history and math.......?
The probability he will pass the history course is .60 and the probability of passing the math course is .70. The probability of passing both is .50. What is the probability of passing at least one of the courses?:
Do I need to know history of Math?
If you approach math history with the "I have to" burden - waste of time I would think. But it helps enormously. Just that (my opinion) you have to know and feel much of math before. But do not approach it as a separate, "have to be done systematically" subject. You work in a concrete field, on a concrete problem? You started to feel reasonably comfortable? Then go to the library, dust off some paper by the very first pioneers - chances are you will get the insight you did not have before.
How would you study for History of Mathematics midterms and final exam?
Be sure to review previous midterms and finals to see what kinds of questions were asked. The exact same questions probably won’t appear on your exams, but at least you’ll know the format of the test and the kinds of questions that will be asked. (Of course, this advice applies to other courses, not just to history of mathematics.)It’s best to do this some time before the test comes up since it will help you to focus on what to study as the course progresses.
