Answer:
D. The number of phone calls made daily from an office

Explanation:
A continuous random variable is defined as a variable where the data can have an infinite number of possibilities.

Let's check the given options:
1- Option A:
The number of employees in an office is fixed. It will not change from one day to another. Therefore, the variable does not have infinite possibilities
............> This option is incorrect

2- Option B:
The salaries of employees in an office are fixed. They will not change from one day to another. Therefore, the variable does not have infinite possibilities
............> This option is incorrect

3- Option C:
The number of printers in an office is fixed. It will not change from one day to another. Therefore, the variable does not have infinite possibilities
............> This option is incorrect

4- Option D:
The number of phone calls made daily from an office is not fixed. They could be any number and can change daily. Therefore, the variable has infinite possibilities
............> This option is correct

Students in a class are asked to stand in ascending order according to their heights for the annual class photograph. Determine

horrorfan [7]

Answer:

The function in Python is as follows:

def heightChecker(heights):

expected = []

count = 0

for i in range(len(heights)):

expected.append(heights[i])

expected.sort()

for i in range(len(heights)):

if expected[i] != heights[i]:

count+=1

return count

Step-by-step explanation:

Required

Function to return the number of out of position students

See comment for complete question

This defines the function. It receives the heights as a parameter, from the main

def heightChecker(heights):

This initializes a list, (expected list)

expected = []

This initializes the count of out of position students

count = 0

This iterates through the original list

for i in range(len(heights)):

The list item is then appended to the expected list

expected.append(heights[i])

This sorts the expected list in ascending order

expected.sort()

This iterates through the original and the expected lists

for i in range(len(heights)):

If list elements at the same index are not the same, count is incremented by 1

if expected[i] != heights[i]:

count+=1

This returns count

return count
