In a study of reaction times of dogs to a specific stimulus, an animal trainer obtained the following data, given in seconds. 3.9 8.2 6.3 8.3 5.2 4.9 7.5 6.9 5.0 7.1 7.0 7.4 5.5 4.6 6.4 6.7 8.5 6.6 7.3 4.3 5.1 8.5 2.5 6.6 6.2 7.9 7.3 3.3 7.2 7.9 7.5 7.7 5.0 5.3 4.1 7.2 8.7 6.6 6.0 3.7 6.3 9.0 7.2 9.5 2.1 3.1 7.2 8.5 4.5 7 8 8.1 4.9 3.5 5.2 6.0 2.8 8.0 8.6 6.1 8.7 7.3 9.4 7.3 4.3 4.8 4.4 4.8 4.4 4.8 4.4 (i) Estimate the number of classes and class width using the Surges’ Rule and corrected to one decimal place (ii) Construct a grouped frequency distribution for the given data. (iii) Compute the mean, median, mode and the standard deviation. (iv) Compute the coefficients of variation

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
