A study found that the mean amount of time cars spent in drive-throughs of a certain fast-food restaurant was 144.1 seconds. Assuming drive-through times are normally distributed with a standard deviation of 29 seconds, complete parts (a) through (d) below. (a) What is the probability that a randomly selected car will get through the restaurant's drive-through in less than 104 seconds? The probability that a randomly selected car will get through the restaurant's drive-through in less than 104 seconds is nothing. (Round to four decimal places as needed.) (b) What is the probability that a randomly selected car will spend more than 190 seconds in the restaurant's drive-through? The probability that a randomly selected car will spend more than 190 seconds in the restaurant's drive-through is nothing. (Round to four decimal places as needed.) (c) What proportion of cars spend between 2 and 3 minutes in the restaurant's drive-through? The proportion of cars that spend between 2 and 3 minutes in the restaurant's drive-through is nothing. (Round to four decimal places as needed.) (d) Would it be unusual for a car to spend more than 3 minutes in the restaurant's drive-through? Why? The probability that a car spends more than 3 minutes in the restaurant's drive-through is nothing, so it __ would not would be unusual, since the probability is less greater than 0.05. (Round to four decimal places as needed.) Enter your answer in each of the answer boxes.

Lian is deciding which of two gyms to join. each gym charges a monthly rate plus a one-time membership fee. lian correctly wrote and solved a system of linear equations by substitution to compare the costs of the memberships. in her work, she substituted an expression for one variable and solved for the other. this resulted in the equation 75 = 75. what can lian conclude? one gym charges $75 per month. each gym charges $75 per month both gyms charge the same monthly rate and the same membership fee. both gyms charge the same monthly rate, but not the same membership fee.
