Consider the reaction below at 25°C for which ΔS = 16.1 J/K. Show your work.
CH4(g) + N2(g) = HCN(g) + NH3(g)
At what temperature will this reaction be spontaneous?
The average pre-school cost for tuition fees last year was ₱14,200. The following year, 20
institutions had a mean of ₱13,100 and a standard deviation of ₱2,250. Is there sufficient evidence
at 𝛼= 0.10 level of significance to conclude that the mean cost has increased?

Tammy has a circular garden with a diameter of 36 feet. She will create 4 stone
pathways in the garden that will form an inscribed quadrilateral in her circular
garden. Tammy wants the straight-line distance between one pair of opposite
vertices to be 36 feet. She also wants two consecutive pathways to have
lengths of 24 feet and 12 feet. Tammy will plant marigolds along the shorter edge of
the garden that is cutoff by the pathways of lengths 24 feet and 12 feet.
What length, to the nearest tenth of a foot, of the edge of the garden will be planted
with marigolds?
what's the probability of Rolling an even number on a die and then flipping a coin that lands on heads give your answer as a reduced fraction
A 2.65 g sample of a gas occupies a volume of 650 mL at 100°C and 753 torr. What is the molecular weight of the gas? [R = 0.0821 L-atm/mol-K]
Write a program to take input for n number of employee records and write records of all employees in a file named: “record1”. Also write records of all those employees in another file named: “record2” who are taking salary more than 50,000. After writing records in both files, merge their contents in another file: “finalrecord” and read all records of “finalrecord” file and display on screen. [Attributes of employee: emp_id, emp_name, emp_experience, emp_salary]
A population consist of numbers 2 5 6 8 and 9, construct the sampling distribution of sample mean with sample size of 3. make a histogram of the distribution.
A bus is moving at 5.0 m/s when a passenger walks forward at 1.5 m/s relative to the bus. How fast is this passenger moving as seen and measured by (a) a person waiting at the bus stop and (b) the driver of the bus?
Write a program that reads a list of integers, and outputs whether the list contains all multiples of 10, no multiples of 10, or mixed values. Define a function named IsVectorMult10 that takes a vector as a parameter, representing the list, and returns a boolean that represents whether the list contains all multiples of ten. Define a function named IsVectorNoMult10 that takes a vector as a parameter, representing the list, and returns a boolean that represents whether the list contains no multiples of ten.
Then, write a main program that takes an integer, representing the size of the list, followed by the list values. The first integer is not in the list.
The program must define and call the following two functions. IsVectorMult10 returns true if all integers in the vector are multiples of 10 and false otherwise. IsVectorNoMult10 returns true if no integers in the vector are multiples of 10 and false otherwise.
bool IsVectorMult10(vector<int> myVec)
bool IsVectorNoMult10(vector<int> myVec)
3. Here We Go Again
by CodeChum Admin
This one’s probably one of the most popular recursion problems in programming. Your task is to create a recursive function that prints out the the first up to the nth number in the Fibonacci sequence by going through the numbers using recursion.
In case you forgot, here is the definition of a Fibonacci sequence:
- fib(n) = 1 if n = 1 or n = 2
- fib(n) = fib(n-1) + fib(n-2) when n > 2
Instructions:
- In the code editor, you are provided with an initial code with a main() that asks the user for an integer n, which represents the number of elements in the Fibonacci sequence to be printed out.
- In addition, you are also provided with an initial displayFibonacci() function which contains the code to supposedly display the first n elements in the Fibonacci sequence. However, it is not working as expected.
- Your task is to find where the error is and fix the displayFibonacci() function.
