1. Factor a trinomial whose leading coefficient is 1. Pick any one of the problems and solve the trinomial. If the trinomial is prime, state this and explain why. a. x2+8x+15 b. x2–4x –5 c. x2–14x+45 2.
The first section in the book is about factors and multiples. In this section McKellar discusses prime numbers and prime factorization. She covers the definition of a factor, a prime number, and a prime factor. She also shows two techniques for factoring factor trees and EZ divisibility tricks. EZ divisibility tricks were something that was new to me so, I was really interested in them they are ways to test numbers to see what their factors may be.
Practice Test 4 –Bus 2023 Directions: For each question find the answer that is the best solution provided. There is only one correct answer. 1. For a sample size of 30, changing from using the standard normal distribution to using the t distribution in a hypothesis test, a. will result in the rejection region being smaller b. will result in the rejection region being larger c. would have no effect on the rejection region d. Not enough information is given to answer this question. ANSWER: a -recall that all the t-values are larger than the z-values so it makes it more difficult to reject the null.
Of course, the serious Scrabbler will be more likely to recognize AA as an indispensable vowel-dump, and the very first word in the Official Scrabble Dictionary. It is also the least interesting palindrome I know. BANNS npl. A formal proclamation announcing intent to marry. This word jumped out at me when I was watching the very word-buff-esque documentary Spellbound.
What are you going to do with the outlier? Please provide a rationale for your decision. (0 marks as this question is part of data screening for the writing of the results in Task 10) Participant two’s score was changed to 256, which was one unit higher than the next most extreme score identified. Perform data screening. Was there a normal distribution?
Assignment #2 1) Improve the result from problem 4 of the previous assignment by showing that for every e> 0, no matter how small, given n real numbers x1,...,xn where each xi is a real number in the interval [0, 1], there exists an algorithm that runs in linear time and that will output a permutation of the numbers, say y1, ...., yn, such that ∑ ni=2 |yi - yi-1| < 1 + e. (Hint: use buckets of size smaller than 1/n; you might also need the solution to problem 3 from the first assignment!) 2) To evaluate FFT(a0,a1,a2,a3,a4,a5,a6,a7) we apply recursively FFT and obtain FFT( a0,a2,a4,a6) and FFT(a1,a3,a5,a7). Proceeding further with recursion, we obtain FFT(a0,a4) and FFT(a2,a6) as well as FFT(a1,a5) and FFT(a3,a7). Thus, from bottom up, FFT(a0,a1,a2,a3,a4,a5,a6,a7)
There are many people in this world do jobs they don't like, but have to do it because they don't have any other ways of income. What come in your mind when you see an average joe win a million dollar using his skill and doing the thing he loves. This will take us back to the picture that I used to present in the class. It was a stage photo of Joseph Cada the World Series Of Poker Main Event champion. The picture was taken few minutes later after he won his 8.5 million dollar first prize in the event.
Radicals Tips 1. Make sure that one of the two factors of the radicand (expression under the radical) is the largest perfect square: Example: Simplify 72 Correct 72 = 36 ∙ 2 = 62 Incorrect 72 = 9 ∙ 8 = 38 2. To be able to add or subtract radicals, the radicands must be the same. Example 1: Add 32 + 52 Answer: Since radicands are the same, (3 + 5)2 = 82 Example 2: Subtract 73 - 3 Answer: (7 – 1)3 = 63 Example 3: 318 - 52 (Must simplify first) 39 2 - 52 3 ∙ 3 ∙ 2 - 52 92 - 520 Answer: 42
Assessment 01.03 Module One Quiz. 1. Splott and Fizzle were solving for 2x+4=-3x+14. Both of them made some errors like when 2x+4=-3x+14 what they should have done was change the sign from -3x to +3x and moved it to the other side with the 2x, put both variables together, which would have been (2x+3x) +4= (+3x where the –3x was which is canceled out) +14, when solved it would have been 5x+4=14, then you would do the opposite of +4 to -4 to its original (the variable number is on one side with the equal sign) and subtracted from the 14 so It would come out to 5x=14-4 you solve 5x=10, divide by 5, x=10 over 5 solve for x, it would be 2 2. The function I created would be f(x) = 6x+11 3.
