On the distant planet cowabunga, the weights of cows have a normal distribution with a mean of 453 pounds and a standard deviation of 73 pounds. the cow transport truck holds 6 cows and can hold a maximum weight of 3018. if 6 cows are randomly selected from the very large herd to go on the truck, what is the probability their total weight will be over the maximum allowed of 3018? (this is the same as asking what is the probability that their mean weight is over 503.)

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?
