There is a number written on the board. One student increased the number by 23, but another student decreased the same number by 1. The first student’s result was 7 times greater than the result of the second student. What is the number written on the board?

Airline passengers arrive randomly and independently at the passenger-screening facility at a major international airport. the mean arrival rate is 10 passengers per minutes. compute the following probabilities. p(x = 4) p(x > 11)

Which is the graph of f(x) = (4)x? image for option 1 image for option 2 image for option 3 image for option 4

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.)
