An average of 20 cars per hour arrive at the drive-in window of a fast food restaurant, where the interarrival times are exponentially distributed. Assume that the service time for each car is exponentially distributed with a mean of 2 minutes. Due to concerns about safety, the restaurant management is considering implementation of a rule to limit the queue length to three cars. (That is, if three cars are in the waiting line for service, another car cannot enter the waiting line until the queue length is 2 or fewer.) If such a rule is instituted, what is the (long-run) percentage of time that cars will be unable to enter the queue

the thermometer is precise but not accurate

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
