number of moving glasses by half. Here is another classical problem similar to the one just described but a little more difficult. There are n things lined up next to another n things like this : XXX.....OOO........ However, we define a different way to "move", where you can only move any pair of neighbouring items to an empty space in a row, and you can't change the left-right order of the items. Then, let we think, it is meaningless when n=1, and when n=2 it is no answer. When n=3,the solution process is as follows. XXXOOO XOOOXX XOO XOX OXOXOX ,it should look like this, and we can move .. So when n > 2,we should at least move n times to solve the problem, could you formulate the solution process for n greater than or equal to 3?
The fourth door is very tricky. It has a 4-number lock to escape consisting of the numbers from 1 to 36. Here are your clues: a. The first number is the sum of the digits in the year that Gottfried Leibniz published his works on Calculus. c. The third number is the sum of the digits of the year that Newton died. d. The last number is the 5th and 6" decimal digits in order of V57.
What if our number had exactly 2 digits to the right of the decimal point? Could I find a number larger than 27.4 that would still round down to 27? What is the largest possible value it could have?
please solve
You’ll want to use nCr or nPr on your calculator for these first three problems. They are very time- consuming to compute by hand. Remember to use nPr when the order matters and nCr when it does not. You will find both commands by pressing the [MATH] key on your calculator and scrolling over to PROB. The factorial (!) is in this list as well. How many different samples of size 35 may be selected from a population of size 120? How many ways can positions 1 through 10 be decided in a 40-car automobile race? A 40-person city council consists of 21 men and 19 women. If the council president randomly selects 10 council members to work on a community outreach project, how likely is she to pick exactly 5 men and 5 women.
Prompt (Dr. James Stewart is the author of Calculus: Single Variable Calculus with Early Transcendentals (8th Edition). The following problem was borrowed from an earlier version of his work.) There is a bit of trivia about the author of the aforementioned textbook, Dr. James Stewart, that few people know. He has an evil twin sister named Shasta. Although he loves his sister dearly, she dislikes him and tries to be different from him in all things. Last winter, they both went on vacation. Dr. Stewart went to Hawaii. Shasta had planned on going to Aruba, but she decided against it. She hates her brother so much that she was afraid there would be a chance that they might be experiencing the same temperature at the same time, and that prospect was distasteful to her. So she decided to vacation in northern Alaska. After a few days, Dr. Stewart received a call: "This is Shasta. I am cold and uncomfortable here. That's good, since you are undoubtedly warm and comfortable, and I want us to be…
The following problem is that of discrete mathematics. Determine whether the statement is true or false. Justify your answer with a proof or a counterexample, as appropriate. The difference of any two odd integers is even.
Please help me in this two problem

The above PERT chart shows the different tasks they need to complete from ideation (A) to commercialization (H), the lengths each will take in months, and the dependencies between tasks. How long is the critical path according to the PERT chart? How long is the shortest path according to the PERT chart? 3 end H
The notation A*B*C is shorthand for “the point B is between point A and point C.” Can I please see the correct proof for the problem taking this notation into account?
is there a shorter way to do this where you don't get decimals in your answer?
