4. (Prime Numbers) An integer is said to be prime if it is divisible by only 1 and itself. For example, 2, 3, 5 and 7
are prime, but 4, 6, 8 and 9 are not.
Write a function called isPrime that receives an integer and determines whether the integer is prime or not.
Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000.
Display 10 numbers per line.
(Count the letters in a string) Write a function that counts the number of letters in a string using the following header: def countLetters(s) : Write a test program that prompts the user to enter a string and displays the number of letters in the string.
the answer should be in python.
5.
(Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve the
following 2 X 2 system of linear equation:
ax + by = e
cx + dy = f
●
x =
ed - bf
bc
ad
y =
af - ec
ad
bc
-
Write a program that prompts the user to enter a, b, c, d, e, and f and display the
result. If ad- bc is 0, report that The equation has no solution.
Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0 Enter
x is -2.0 and y is 3.0
Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0 Enter
The equation has no solution

The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forward(Bar-Chart Printing Program) One interesting application of computers is drawing graphsand bar charts. Write a program that reads five numbers (each between 1 and 30). For each numberread, your program should print a line containing that number of adjacent asterisks. For example,if your program reads the number seven, it should print *******.arrow_forward
- Q3. (Dice Rolling) Write a program that simulates the rolling of two dice. The program should use rand to roll the first die and should use rand again to roll the second die. The sum of the two values should then be calculated. [Note: Each die can show an integer value from 1 to 6, so the sum of the two values will vary from 2 to 12, with 7 being the most frequent sum and 2 and 12 being the least frequent sums.] Figure 7.26 shows the 36 possible combinations of the two dice. Your program should roll the two dice 10,000 times. Use a one-dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals are reasonable (i.e., there are six ways to roll a 7, so approximately one-sixth of all the rolls should be 7). 1 2 3 4 5 1 2 4 6 7 3 4 6 7 3 4 5 7 8 9 4 7 8 9 10 7 8 10 11 7 10 11 12 Row\Col 3.arrow_forwardQ2) (Perfect Numbers) An integer number is said to be a perfect number if its factors, including 1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 = 1 + 2 + 3. Write a function perfect that determines if parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect. Challenge the power of your computer by testing numbers much larger than 1000.arrow_forwardplease quickly thanks !! use Pythonarrow_forward

Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight. Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart: When does the worker typically take lunch? Did the worker do work on the weekend?
