Alexis is a 14-year-old gymnast. Her days are
extremely busy. She wakes up at 7:00 AM and needs to be at school
by 7:30 AM. Breakfast is usually eaten in the car on the way to
school; lunch is purchased in the school cafeteria. The school day
lasts until 3:00 PM, after which she heads to the gym. Practice
runs from 3:30 PM until 7:00 PM. After her parents pick her up from
the gym, they typically go to a casual dining or fast-food
restaurant for dinner. Once Alexis arrives at home, she has 1–2
hours to complete her homework and prepare for the next day. She is
frustrated by always eating on the run. Alexis is also concerned
that her convenience food diet is not fueling her body properly for
gymnastics.
Questions: Provide two options for quick, healthy meals/snacks for
each of the following: breakfast, lunch, afternoon snack, and
dinner. Nutrition recommendations should be appropriate for the
sport of gymnastics. Suggestions can be given to both Alexis and
her parents.

Hw questions
1. Write a single C++ statement that will:
Print the string “C++” using the variable: string s = “Introduction to C++”.
2. Change the letter ‘c’ to ‘C in the following string:
Reprint the string with “C” given the code and using the string: string greeting = “Introduction to c++”
3. Write the C++ statement or statements that will:
Print the answer for regular division of the real numbers a / b + c and print the answer for integer division of the same values for integer numbers d / e + f.
For example, given float a=13, b=3, c = 10, the statements would print :
Regular division result = 14.3333
Integer division result = 14
4. Write the C++ statement or statements that will generate a random number between 100 and 110:
5. Write a C++ statement or statements that will:
Print the first two digits and the last two digits of any 4 digit number stored in an integer variable n.
For example, given int n = 5623, print
56 23.
6. Write C++ statements that will align the following three lines as printed in two 20 character columns.
Name Years President
Abraham Lincoln 1860-1865
Thomas Jefferson 1801-1809
7. Write a C++ statement or statements that will Output if a string has a length greater than 10, equal to 10 or less than 10.
Examples :
string str1 = “Four Score and Seven Years Ago” would output “String Length > 10”
string str2 = “Good Day” would output “String Length < 10”
string str3 = 0123456789” would output “String Length = 10”
8. Create a truth table and determine the results for the following equation and values
Equation : bool b = ((a+4< 7) || ((b-a > 10) && !(c*a == 8)))
Values : a = 2; b = 8; c = 4
9. Write a program using Atom and submit via Blackboard.
a. Request an integer whole dollar amount from the console.
b. Using the least amount of bills ($50,$20,$10,$5,$1) necessary, calculate how many of each bill type you will need to get to that value.
Output Example 1 (input is bold and italicized)
Enter a whole dollar amount as n integer: 633
You will need:
12 $50 bill(s).
1 $20 bill(s).
1 $10 bill(s).
0 $5 bills(s).
3 $1 bill(s).
Output Example 2 (input is bold and italicized)
Enter a whole dollar amount as an integer: 364
You will need:
7 $50 bill(s).
0 $20 bill(s).
1 $1 bill(s).
0 $5 bills(s).
4 $1 bills(s).

Inter State Moving and Storage Company is setting up a control chart to monitor the proportion of residential moves that result in written complaints due to late delivery, lost items, or damaged items. A sample of 60 moves is selected for each of the last 12 months. The number of written complaints in each sample is 8, 9, 3, 6, 1, 5, 10, 7, 7, 8, 8, and 10.
1. Insert the mean proportion defective, UCL, and LCL. (Round your intermediate calculations and final answers to 2 decimal places.)

2. Does it appear that the number of complaints is out of control
for any of the months? Yes or No?
Thank you!

During the last shot in a curling match, you attempt a take-out to win the game. The two curling rocks are of equal mass, one red and the other blue, and collide in a glancing collision. The blue rock is initially at rest and is struck by the red rock moving initially East at 4.60 m/s. After the collision, the red rock moves in a direction that makes an angle of 38.0° North of East, while the blue rock makes an angle of 52.0° South of East. Determine the speed of each rock after the collision.

Below is an English algorithm for determining the day of the week (Sunday, Monday, etc.) given the date (day, month and year).
Take the last two digits of the year.
Divide by 4, discarding any fraction. (keep quotient;
ignore remainder)
Add the day of the month.
Add the month's key value: JFM AMJ JAS OND 144 025 036
146
[eg, Jan = 1; Feb = 4; March =4; etc] & see note [a]
Subtract 1 for January or February of a leap
year.
For a Gregorian date, add 0 for 1900's, 6 for 2000's,
4 for 1700's, 2 for 1800's; for other years, add or subtract
multiples of 400.
see note[c]
For a Julian date, add 1 for 1700's, and 1 for every
additional century you go back.
see note [b]
Add the last two digits of the year.
Divide by 7 and take the remainder.
Now, 1 is Sunday, the first day of the week, 2 is Monday, and so
on.
You have been put in charge of planning the New Year’s Eve party for the Computer Science Department. Your initial task is to determine which day of the week New Year’s Eve will fall on for any given year. To do so, implement the above algorithm in Python with the following abstractions (simplifications):
Assume that the date to be evaluated will always be
December 31st (in step 4, you will always add
6)
Assume that the date will always be Gregorian (you
will always ignore step 7)
Assume that the year will always be in the 2000s (in
step 6, you will always add 6)
Bonus: If you are an experienced coder, feel free to modify
the program to calculate the day of the week for any date, not just
December 31. This will require the use of conditionals for step 4
and step 6.
Submit your code (as a .py file or a plain .txt. file) here on Blackboard. Ensure that your code runs before you submit, and ensure the indentation is preserved in the file.
Hints: start by following the steps manually to ensure you understand the algorithm
create three variables (with appropriate names) and assigning them the numeric values of the day, month, and year (last two digits); use another variable (or more) to hold the intermediate results
remember that remainder is determined using the modulo operation (%).

A pharmaceutical company will spend $1,500,000 each year for 3 years to develop a new drug (years 0, 1, 2). After that (starting year 3), they will earn $900,000 in profits per year for 8 years before thepatent runs out. No extra profits after the patent is gone. If future payments are discounted using a 10% interest rate (compounded annually), is this new drug a profitable venture? Should you lease or buy equipment?
