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)?

what level of math? also i don't need to be paid if i can you.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.

step-by-step explanation:

its payment history because your score is mainly based on how consistent u are with your payment and if there on time. hope this : )

the result can be shown in both exact and decimal forms.

exact form; 76 · 75, 4911, 4935, 711, 735

decimal form: 5700, 4911, 4935, 711, 735
