What is meant by the phrase a consistent method of measurement?
measurements are taken in a way that is the same every time. - apex
What is a time series in maths?
Time series is a method of using past data to predict future values. It is based on the assumption that there is an undelying trend to the data. To predict future values, we use the concept of moving averages.
How can we quickly order data and at the same time reveal the distribution shape?
A bar graph of frequency against category, value or range of values is the best method.
Is there anywhere to get answer key for 3-2-1 code it workbook by michelle a green?
Only someone teaching a class using the book can purchase the book. My instructor because she is a fill in is having a hard time purchasing the book.
How do you solve an equation by factoring?
In the special case when a =1, the factoring method results in finding 2 NUMBERS knowing their sum and their product. The process is simple. However, when the constants a, b, c are large numbers, and contain themselves many factors, then the factoring method becomes complicated and takes long time in the process. For examples, solving these equations by the factoring method will take lot of time because of the high number of permutations: (6x^2 - 11x - 35 = 0) ; (45x^2 + 74x - 55 = 0) ; (45x^2 - 152x - 36 = 0); (12x^2 + 5x - 72 = 0) There is a new method, called Diagonal Sum Method, that can quickly and directly give the 2 roots, WITHOUT HAVING TO FACTOR THE EQUATION. The innovative concept of the new method is finding 2 FRACTIONS knowing their sum (-b/a) and their product (c/a). It is faster, more convenient than the factoring method since it requires fewer permutations by using the rule of signs for real roots. It is applicable whenever the equation can be factored. So, I advise you to proceed solving any quadratic equation in 2 steps. First step, use the Diagonal Sum method to solve it. It usually takes fewer than 3 trials. If it fails, then the quadratic formula must be used in second step. See book title:" New method for solving quadratic equations and inequalities" (Trafford Publishing 2009)
