### How many points?

Problem: How many points? A certain homework help website awards R user points for registration, Q user points for an approved question, A user points for an approved answer, and an additional B user points for an answer that is selected as the Best Answer.    Using an expression involving R, Q, A and B, how many points does a registered user get for posting 10 questions, submitting 50 answers, and having 5 answers selected as Best Answer? (All questions and answered are approved.)    What is the expression for the total number of points awarded for an answer that is selected as Best Answer? Part 1:   P = R + 10Q + 50A + 5B Part 2:   T = A + B Sounds like a website I would be interested in.

### statistic probability

i. All the possible answers in Quiz 1 by chance can be represented by the terms in the expansion of (0.25+0.75)^8, where 0.25 is the probability of a correct choice of answer for each individual question and 0.75 is the probability of an incorrect choice of answer. The binomial expression has a value of 1, which is a probability of 1, i.e., certainty, made up of the sum of all the terms. Let p=0.25 and 1-p is 0.75. The expansion is p^8+... + 8Cr*p^r(1-p)^(8-r), where r indicates the rth term between r=0 and 8 and 8Cr is the combination function nCr for n=8. The value of 8Cr is given by (8*7*...*(8-r+1))/(1*2*...*r). The coefficients are, in order: 1, 8, 28, 56, 70, 56, 28, 8, 1, the 8th row of Pascal's triangle. The binomial terms start with the probability of 8 correct answers, then 7 correct 1 incorrect, 6 correct 2 incorrect, 5 correct 3 incorrect, and so on. The probability of answering incorrectly 3 question is (3/4)^3=27/64, so the probability of answering at least one question in 3 correctly by chance is 1-27/64=37/64, in other words, this is the probability that at most 3 questions are attempted before obtaining a correct answer. This is better than an evens chance (50%), so is more likely than unlikely. ii. In Quiz 2 p=1/5 or 0.20 and n=15. The probability of less than 4 correct answers is the sum of the last four terms of the binomial series for 15, which give all incorrect, 1, 2, 3 correct. The coefficients are respectively 1, 15, 105, 455. The p terms alone are 0.03518, 008796, 0.002199 and 0.0005498. When we multiply by the coefficients and add the terms together we get 0.6482 or 64.82% probability. iii. The probability of 6 or more correct answers in Quiz 1 is 1-(probability of up to 2 incorrect answers)=1-(0.75^8+8*0.75^7*0.25+28*0.75^6*0.25^2)=1-0.6785=0.3215 or 32.15%. This is less than 1/3, so the odds are 2:1 against Siti getting 6 or more correct answers by chance alone, which makes it reasonably unlikely. iv and v. The problem says "before the 8th question", so there need to be 5 correct answers within the first 7 questions. Using p=0.2, the probability of getting 5 correct answers out of 5 is 0.2^5=0.00032; the probability of getting 5 correct out of 6 is 6*0.2^5*0.8=0.001536; and the probability of 5 out of 7 is 21*0.2^5*0.8^2=0.0043008. Therefore the probability of getting 5 correct before the 8th question is the sum of these=0.0061568 or 0.62%, a most unlikely occurrence, less than 1 in 162.

### i need help with finding the answer for the square root of 34

The only step by step way of finding the square root of a number which doesn't radicalise is to use an arithmetic technique as follows: We know that the answer is close to 6 because 6 squared is 36, so there will be decimals. We write digits in pairs thus: | 34 |•00 | 00 | 00 | 00 The answer is in single digits for each pair, so we will be writing the answer over the top. The decimal point is inserted in front of the digit that will go over the first pair of zeroes. I've put in 4 pairs of zeroes so we'll be working out 4 decimal places only. We know the first digit in the answer is 5, because the answer is a little less than 6, so we write 5 over 34. We write the square of 5, i.e., 25, under 34 and subtract it: ..........5...• 8.....3.....0.....9 ...... | 34 |•00 | 00 | 00 | 00 .........25 108 |...900 ...........864 1163 |...3600 .............3489 ................11100 116609 |..1110000 ................1049481 ....................60519 I'm using dots to space out and align the working so that you can see what I'm doing. Now we double 5 to make 10 and we need to guess what digit should follow 10 so that when we multiply by the digit we get a number which is smaller than or equal to the remainder so far, 900. The digit we need to add is 8, so we write 108 and multiply by 8=864, which is a little less than 900. We subtract 864 from 900 leaving 36 and we pull down another pair of zeroes. We write 8 next to the decimal point, so now we have 5.8. The next step is to double the answer we have so far ignoring the decimal point, so we have 116, and again we need to put a digit on the end of this and multiply by the same digit so that the product is as close to 3600 as we can get without exceeding it. Let's guess 3, so we have 1163*3=3489 (note that 4 would be too big). The remainder is 111 and we bring down the next pair of zeroes to make 11100. We carry on. Double the answer so far=1166. What digit are we going to add this time? The smallest is 1, but 11661 is bigger than the remainder 11100, so we have to put zero in the answer and bring down the next pair of zeroes. Double the answer 11660. Now we can add a digit, which is going to be high, so we'll pick 9 and multiply it to give 116609*9=1049481. We could carry on repeating the same process, bringing down pairs of zeroes as necessary. There are other ways of finding square roots, but I find this one fairly straightforward and it doesn't require a calculator. I think this method is based on Newton's method.

### How do I find the answer to (10/11)² - 1/11 • 1 1/12 ? No matter how I work it I'm told my answer is wrong.

How do I find the answer to (10/11)² - 1/11 • 1 1/12= ? No matter how I work it I'm told my answer is wrong. Note: 99 119/132 isn't the answer. I got that by (10/11)² = 100/121, 1/11 • 1 1/12= 13/132, so 100/121 - 13/132 = 99 119/132 Please note that your last computation, 100/121 - 13/132 = 99 119/132 is where you went wrong. You final result, 99 119/132, you would get from, 100 - 13/132 = 99 119/132. It looks as though you simply forgot to divide by 121! The answer is: 100/121 - 13/132 = (100*132 – 13*121) / (121 * 132) 100/121 - 13/132 = (13200 – 1573) / (15,972) 100/121 - 13/132 = (11,627) / (15,972) = 1057/1452  (take out a factor of 11, top and bottom) Answer: 1057/1452

### What are the points for in this website?

A registered user usually gets 40 points for each answer accepted (but not necessarily correct). The points accumulate and this determines what level the user has reached. Users are promoted to the next level as the points pass a boundary determined by the people that control the site. There is no money or other material reward for the points. Points can be adjusted by people promoted to Administrator, who are also granted other privileges not available to other users. Points enable users' performance and activity to be compared, but the longer you have been a registered and active user, the more likely it is that you will accumulate points. If you click on Users in the menu bar, you can see a list of "top users", who have gained sufficient points to be listed. You can also pick a user and see their profile, recent activity, their questions and answers, etc. Remember that points don't always mean that users have answered questions correctly, and there are a lot of wrong answers as well as a lot of right answers! If you see a lot of answers to a particular question, you may be able to work out which answers are correct by examining and comparing answers. If everyone that uses the site asks and answers questions honestly, concisely and clearly, the site will be beneficial to everyone.

### In a mathematics emathematics, each correct answergets 2 marks and a wrong answer attract -1, ola got a total of 19 in aquiz with 20 questions. How many correct answers did he get?

If we call the number of right answers R and the number of wrong answers W, 2R-W=19. Also we know W+R=20. Add the two equations: 3R=39 so R=13, 13 correct answers. 13 correct answers gains 26 points; 7 incorrect answers loses 7 points and 26-7=19.
