please write the code in C format avoid using (<<count>>)

Assume that you work for a travel agency. Write a C program that performs 7 different tasks described below
for this company. The flights have the following
daily departure and arrival times:

a) Based on the time entered by the customer, the closest departure time is displayed using 12- hour format.

b)the customer is asked if they would like a hotel and for how many days. hotel cost is mentioned above. Calculate the total cost (before taxes) and display it (flight + hotel for n number of days +ride).

c) now there is 2 types of discount:
Discount1: If the total fee is a multiple of 11, then the
customer gets a 6% discount.
Discount2: An additional discount of 7% is given to those customers whose subtotal
after discount1 is a multiple of the sum of digits of the customer’s day of birth.
Three examples are given below for your convenience. See Sample Input / output
for more clarification.
• Ex1: If the day of birth entered is 3, the customer will get an additional 7%
discount if the sub-total of their purchase after discount1 is a multiple of 3.
• Ex 2: If the day of birth entered is 12, the customer will get an additional 7%
discount if their purchase after discount1 is a multiple of 3 (since sum of digits of
day of birth (12) is 3).

c)13% tax is applied to the total cost and the final bill is?

Almost all U.S. light-rail systems use electric cars that run on tracks built at street level. The Federal Transit Administration claims light-rail is one of the safest modes of travel, with an accident rate of .99 accidents per million passenger miles as compared to 2.29 for buses. The following data show the miles of track and the weekday ridership in thousands of passengers for six light-rail systems.

1. Use these data to develop an estimated regression equation that could be used to predict the ridership given the miles of track.
   
   Compute b₀ and b₁ (to 2 decimals).
   b₁  
   b₀  
   
   Complete the estimated regression equation (to 2 decimals).
   =  +  x
   
2. Compute the following (to 1 decimal):

   SSE
   SST
   SSR
   MSE

   
   
3. What is the coefficient of determination (to 3 decimals)? Note: report r² between 0 and 1.
   
   
   Does the estimated regression equation provide a good fit?
   SelectYes, it even provides an excellent fitYes, it provides a good fitNo, it does not provide a good fitItem 10
   
4. Develop a 95% confidence interval for the mean weekday ridership for all light-rail systems with 30 miles of track (to 1 decimal).
   (  ,  )
   
5. Suppose that Charlotte is considering construction of a light-rail system with 30 miles of track. Develop a 95% prediction interval for the weekday ridership for the Charlotte system (to 1 decimal).
   (  ,  )
   
   Do you think that the prediction interval you developed would be of value to Charlotte planners in anticipating the number of weekday riders for their new light-rail system?
   SelectYes, because this interval has high accuracyYes, because this interval has high confidenceYes, because this interval has both high accuracy and high confidenceNo, because this interval is too wideNo, because this interval has low confidence

3. Suppose that the production function is CobbDouglas with parameter α = 0.3.

a. What fractions of income do capital and labour receive?

b. Suppose that immigration raises the labour force by 10 percent. What happens to total output (in percent)? The rental price of capital? The real wage?

c. Suppose that a gift of capital from abroad raises the capital stock by 10 percent. What happens to total output (in percent)? The rental price of capital? The real wage?

please explain it like how to they get digits from suddenly out of no where

d. Suppose that a technological advance raises the value of the parameter A by 10 percent. What happens to total output (in percent)? The rental price of capital? The real wage?

String is wrapped around an object of mass M = 0.3 kg and moment of inertia I = 0.01 kg·m2. You pull the string with your hand straight up with some constant force F such that the center of the object does not move up or down, but the object spins faster and faster (see the figure). This is like a yo-yo; nothing but the vertical string touches the object. When your hand is a height y0 = 0.26 m above the floor, the object has an angular speed 0 = 14 radians/s. When your hand has risen to a height y = 0.66 m above the floor, what is the angular speed of the object? Your answer must be numeric and not contain the symbol F.

What is the role of the central limit theorem in solving this problem?

The CO2 content of the air in a 5000 cu ft room is 0.3 percent. Fresh air containing 0.1 percent CO2 is pumped into the room at teh rate of 1000 ft^3/min . A) find the percentage of CO2 in the room after 30 min. When will the CO2 content be 0.2 percent?   ANS) 0.10 percent and 3.47 minutes

Given the following data, use exponential smoothing with a = 0.3 and α =.5 to develop a demand forecasts for period 7.  Assume that the forecast for week 1= 19. Use the Mean Absolute Percent Error to determine which forecasts are more accurate.
