Wendy's restaurant has been recognized for having the fastest average service time among fast food restaurants. in a benchmark study, wendy's average service time of 2.2 minutes was less than those of burger king, chick-fil-a, krystal, mcdonald's, taco bell, and taco john's (qsr magazine website, december 2014). assume that the service time for wendy's has an exponential distribution.
a. what is the probability that a service time is less than or equal to one minute (to 4 decimals)
b. what is the probability that a service time is between 30 seconds and one minute (to 4 decimals)?
c. suppose a manager of a wendy's is considering instituting a policy such that if the time it takes to serve you exceeds five minutes, your food is free. what is the probability that you will get your food for free (to 4 decimals)?

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
