The time until recharge for a battery in a laptop computer under common conditions is normally distributed with mean of 260 minutes and a standard deviation of 50 minutes. a) What is the probability that a battery lasts more than four hours? i (Round the answer to 3 decimal places.) b) What are the quartiles (the 25% and 75% values) of battery life? 25% value = i minutes (Round the answer to the nearest integer.) 75% value = i minutes (Round the answer to the nearest integer.) c) What value of life in minutes is exceeded with 95% probability? i (Round the answer to the nearest integer.)

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
