![]() ![]() If we add 5 to each data value, then the mean and standard deviation become ![]() The mean of a data set is equal to 10 and its standard deviation is equal to 1. The number of different orders in which books A, B and E may be arranged is Books C and D are to be arranged first and second starting from the right of the shelf. The number of different committees that can be formed from 5 teachers and 10 students isįive different books (A, B, C, D and E) are to be arranged on a shelf. Therefore, the three solutions of the equation f(2 x) = 0 areĪ school committee consists of 2 teachers and 4 students. The three solutions of the equation f(x) = 0 are - 4, 8, and 11. Therefore, the three solutions of the equation f(x - 2) = 0 are The three solutions of the equation f(x) = 0 are -2, 0, and 3. The graphs of the two equations y = a x 2 + b x + c and y = A x 2 + B x + C, such that a and A have different signs and that the quantities b 2 - 4 a c and B 2 - 4 A C are both negative,įor x greater than or equal to zero and less than or equal to 2 ?, sin x and cos x are both decreasing on the intervals ![]() The graphs of the two linear equations a x + b y = c and b x - a y = c, where none of the coefficients a, b, c is equal to zero, When a parabola represented by the equation y - 2x 2 = 8 x + 5 is translated 3 units to the left and 2 units up, the new parabola has its vertex at If the graph of y = f(x) is transformed into the graph of 2y - 6 = - 4 f(x - 3), point (a, b) on the graph of y = f(x) becomes point (A, B) on the graph of 2y - 6 = - 4 f(x - 3) where A and B are given by The graph of the new function g defined by g(x) = | f(x) | is a reflection of the graph of f The graph of the new function g defined by g(x) = 2 - f(x - 5) has a range defined by the intervalį is a function such that f(x) < 0. If the population of this country was 2 000 000 on December 31, 2003, then the population of this country on January 1, 2000, to the nearest thousand would have beenį is a quadratic function whose graph is a parabola opening upward and has a vertex on the x-axis. The population of a country increased by an average of 2% per year from 2000 to 2003. If Log 4 (x) = 12, then log 2 (x / 4) is equal to If Log x (1 / 8) = - 3 / 2, then x is equal to Detailed explanations and solutions to these questions are also provided. The questions have been designed to test for deep understanding of maths concepts. The answers are provided and are located at the lower part of the page. Math Questions With Answers Math Questions With AnswersĪ set of multiple choice maths questions are presented. If it’s generally, what’s the closest time next to midnight then it would be 12:03am."ĭon't miss the latest news from around Scotland and beyond - sign up to our daily newsletter here. While a second explained further: "Besides D being the answer, if we’re being technical and using to (as in before, so closest time before midnight (12:00am) the it would be A) 11:55am. Very simple but tricky due to the wording." One person wrote: "I can understand the argument of some to say 11:55 am could be the answer due to the fact that the operative word which is “to” is used but the obvious answer is 12:03 am. ![]() Many takers put the confusion down to the wording of the question, specifically the word "to" as it was interpreted differently. Meanwhile, 12.06am is six minutes past and 11.50am is 12 hours and 10 minutes earlier than midnight. ![]()
