PLEASE SOMEONE HELP ME Participants in a survey were asked whether or not they had a pet and whether their commute to work was longer than 20 minutes
(long commute) or shorter than 20 minutes (short commute). Use the two way frequency table to solve the problem:

To the nearest whole percent, what is the probability that a person selected at random has a short commute and a pet?

Which conjunction is disjunction is equivalent to the given absolute value inequality? |x+2|< 18

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?
