Consider an automobile assembly line in which each car undergoes two types of service: painting, then engine installation. Each hour, an average of 22.4 unpainted chassis arrive at the assembly line. It takes an average of 2.4 minutes to paint a car and an average of 3.75 minutes to install an engine

Question

Consider an automobile assembly line in which each car undergoes two types
of service: painting, then engine installation. Each hour, an average of 22.4
unpainted chassis arrive at the assembly line. It takes an average of 2.4
minutes to paint a car and an average of 3.75 minutes to install an engine.
The assembly line has one painter ant two engine installers. Assume that
interarrival times and service times are exponential
a. On average, how many painted cars without completely installed engines
will be in the facility?
b. On average, how long will a painted car have to wait before installation of
its engine begins?

The value of all goods and services produced in a nation during a specific period of time, as compared to an earlier period, is called the economic growth rate. It measures the change in a nation's gross domestic product (GDP). The United States had an economic growth rate of approximately 2.9%and GDP of approximately $20.58 trillion in 2018. If the economic growth rate is expected to stay the same for the next 3 years, what is the projected GDP for the year 2021? a $21.96 trillion b $23.15 trillion c $22.42 trillion d $22.31 trillion

A popular social media platform has begun offering stock shares to the public. In the past 2 years, the price of the stock has generally increased. An investment specialist gathers data on the stock price during the past 2 years and creates an exponential model for estimating the stock price based on the number of weeks after the first public offering. Based on the scatterplot and computer output, a reasonable estimate for the stock price for week 95 is: O $2.27 because y 0.0022(95) + 2.0583 = 2.2673.
