Here some math for you guys

John makes $10.50 pers hour what expression represens how much he will make if he works h hours

The graph of h(x)= |x-10| +6 is shown. on which interval is this graph increasing

You were told that the amount of time lapsed between consecutive trades on the new york stock exchange followed a normal distribution with a mean of 15 seconds. you were also told that the probability that the time lapsed between two consecutive trades to fall between 16 to 17 seconds was 13%. the probability that the time lapsed between two consecutive trades would fall below 13 seconds was 7%. what is the probability that the time lapsed between two consecutive trades will be between 14 and 15 seconds?
