Round 18.7356 to two decimal place would use the pseudocode?

• ROUND(18.7356, 2)

• ROUND(Distance, 2)

• ROUND(18.7356, 1)

• ROUND(18.7356, 0)

What is the pseudocode to carry out the following? Round 18.7356 to one decimal place

• ROUND(18.7356, 0)

• ROUND(18.7356, 3)

• ROUND(18.7356, 2)

• ROUND(18.7356, 1)

How could you create a random integer between 0 and 100?

• ROUND(RANDOM() * 100, 3)

• ROUND(RANDOM() * 100, 2)

• ROUND(RANDOM() * 100, 0)

• ROUND(RANDOM() * 100, 1)

Explain what the following algorithm does: import statistics ages = [18,2,14,6] a = min(Ages) b = max(Ages) c = sum(Ages) d = statistics.mean(ages) ages.sort() print(ages) print(a,b,c,d) if 14 in ages: print("14 present")

• Prints the sorted ages and their minimum, maximum, sum, and mean. Then checks if 14 is present in the ages.

• Prints the sorted ages and their maximum, minimum, sum, and mean. Then checks if 14 is present in the ages.

• Prints the sorted ages and their sum, minimum, maximum, and mean. Then checks if 14 is present in the ages.

• Prints the sorted ages and their mean, maximum, minimum, sum. Then checks if 14 is present in the ages.

What would the pseudocode be to convert the floating point number stored in totalBill to two decimal places?

• ROUND(totalBill, 3)

• ROUND(totalBill, 1)

• ROUND(totalBill, 2)

• ROUND(totalBill, 0)

How could you simulate the throw of a dice?

• import random dice = random.randint(1, 5) print(dice)

• import random dice = random.randint(0, 5) print(dice)

• import random dice = random.randint(1, 6) print(dice)

• import random dice = random.randint(0, 6) print(dice)

A random number between 0 and 100 can be generated with a statement such as

• RANDOM() * 102

• RANDOM() * 99

• RANDOM() * 101

• RANDOM() * 100

What is an algorithm for finding the minimum number from an array of numbers?

• Iterate through the array and sum all the numbers.

• Iterate through the array and compare each number with the current maximum.

• Iterate through the array and compare each number with the current minimum.

• Iterate through the array and count the number of elements.

What is the pseudocode to carry out the following? Round a variable Distance (in metres) to the nearest cm

• ROUND(Distance, 2)

• ROUND(Distance, 1)

• ROUND(Distance, -1)

• ROUND(Distance, 0)

What is the result of the following library routines that are written in pseudocode? RANDOM()

• A random number between 0 and 1

• A random number between 1 and 10

• A random integer between 0 and 100

• A random integer between 1 and 100
