The mean marks obtained by 9 students of class 6 in an exam is 50 among them the marks obtained by 8 students are 60, 40, 50,30,80,40,45 and 40 what is the marks of remaining one student?

Question 5 spring semester final exam math evaluate

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

15/16 as a decimal rounded to the nearest hundredth
