A common test for divisibility by 3 is to add the individual digits of an integer. If the resulting sum is divisible by 3 then so is the original number. Program this test. To do this, first define a function: reduce(number) which returns the sum of the digits of the number argument. The sum returned must be < 20 i.e. if the sum is >= 20, the function must add the digits of the resulting sum. It should repeat this procedure until the sum is < 20. Use this function in a python program that inputs an integer from the user and prints out whether or not the integer is divisible by 3.

Answers

Answer 1

The function to test for divisibilty by 3 will accept an input integers and divide it by three to check if its divisible by 3.

The function to test for divisiblity by 3 is as follows:

integer = input("input the integer to check if it's divisible by 3: ")

def reduce(integer):

list1 = []

sum1 = 0

for i in str(integer):

list1 += i

results = list(map(int, list1))

for x in results:

sum1 += x

if sum1 < 20 and sum1%3==0:

return "The integer is divisible by 3"

elif sum1 < 20 and sum1%3 != 0:

return "The integer is not divisible by 3"

else:

while sum1 >= 20:

z = sum(list(map(int, list(str(sum1)))))

if z%3==0:

return "The integer is divisible by 3"

else:

return "The integer is not divisible by 3"

print(reduce(integer))

Code explanationThe integer variable stores the users input.We define a function called "reduce". The reduce function accepts the interger variable as a parameter.The code loop through the integer and check if it is divisible by 3. If the sum of the integer number is greater or equals to 20, we divide the resulting sum by 3 .If the integer is divisible by 3, we return "it is divisble by 3" and if it is not dividible by 3, it will return "it is not divisble by 3".

A zero tolerance policy is one that penalizes every violation of a stated rule. People in positions of authority are prohibited by zero tolerance policies from exercising discretion or changing punishments to fit the circumstances subjectively. They must impose a predetermined punishment regardless of individual guilt, extenuating circumstances, or history.

Zero tolerance policies are studied in criminology and are used in both formal and informal policing systems worldwide. If an employee violates the policy, there will be no tolerance and they will be fired.

Therefore, a zero-tolerance policy means that if the employee violates the policy, they will be fired.

What does the standard deviation of a set of data tell you?
O A. The smallest data value
B. Whether the data are spread out or not
O C. How many data points there are
O D. The maximum value of the data
SU

Answers

Answer: It tells us about how our set of data is spread out as compared to our mean or expected value.

Explanation: Note: Standard deviation is represented by Greek Letter sigma.For example: A teacher in a class of particular students takes a learning ability test from the students. Average or mean marks of students is 52 with +/- 10 marks. Then 1σ (Sigma = standard deviation) it means 1 standard deviation = 68% students will lie in between 52 + 10 =62 marks and 52-10 = 42 marks region. 2σ (2 standard deviation) means among the students 95% of them will lie between 52 + 20 =72 and 52-20= 32 marks region.3σ (3 standard deviation) means 99.7% of the students will lie in the region where 52 + 30 = 82 and 52 – 30 = 22 marks region. So for 3σ (3 Standard Deviations), only 0.3% of the total students deviate +/-30 marks from the average. It means 0.15% students will have marks less than 22 and 0.15% students will have marks greater than 82. In the schematic attached, I have tried to make you understand through a diagram. Please refer to the schematic 1. It tells us about the how our set of data is spread out as compared to our average or mean. And distance from mean can be calculated through number of standard deviations that the data is how much below or above the average.For example:For 1σ 68% students will come under the curve of “Average Learners” and rest of 32% will come under the curve of “Poor Learners” and “Very Talented Learners”.For 2σ 95% of the students will come under the curve of “Average Learners” and rest will come under the curve of “Poor Learners” and “Very Talented Learners”.For 3σ 99.7% of the students will come under the curve of “Average Learners” and rest of 0.3% will come under the curve of “Poor Learners” and “Very Talented Learners”.

A sort function sorts in an ascending or desceding order

The true statement is that the function would sort in decreasing order.

What is a sort function?

A sort function is a code segment that is used to reorder a list in ascending or descending order, when called or evoked

The order of the sort function

The code segment is given as:

if (list[index] < list[index + 1]) {

temp = list [index];

list[ index] = list [index +1];

list[index +1] = temp;

}

In the above code, we can see that the code compares a list element with the next element on the list, and the larger value comes to the front

This means that the sort function sorts in decreasing order

Answer:

Using Someone else's idea without giving him or her credit

Answer:

Explanation:

Consider the following program written in C syntax:
void swap(int a, int b) {
int temp;
temp = a;
a = b;
b = temp;
} void main() { int value = 2, list[5] = {1, 3, 5, 7, 9};
swap(value, list[0]);
swap(list[0], list[1]);
swap(value, list[value]);
}
For each of the following parameter-passing methods, what are all of the
values of the variables value and list after each of the three calls to
swap?
1. Passed by value
2. Passed by reference
3. Passed by value-result
6.

Answers

The values of the variables value and list after each of the three calls to

swap are:

value = 2 and list[5] = {1, 3, 5, 7, 9};value = 2 and list[5] = {3, 1, 5, 7, 9};value = 2 and list[5] = {3, 1, 5, 7, 9};

How to determine the values of variable value and the list?

1. Passed by value

In this case, the values of the actual arguments remain unchanged; So the variable value and the list would retain their initial values

The end result is:

value = 2 and list[5] = {1, 3, 5, 7, 9};

2. Passed by reference

With pass by reference, the arguments are changed.

Given that

value = 2 and list[5] = {1, 3, 5, 7, 9};

The value of variable value is swapped with list[0].

So, we have:

value = 1 and list[5] = {2, 3, 5, 7, 9};

Then list[0] and list[1] are swapped

So, we have:

value = 1 and list[5] = {3, 2, 5, 7, 9};

Lastly, value and list[value] are swapped

So, we have:

value = 2 and list[5] = {3, 1, 5, 7, 9};

The end result is:

value = 2 and list[5] = {3, 1, 5, 7, 9};

3. Passed by value-result

Since there is no loop in the program, the pass by value-result has the same output as the pass by reference.

So, the end result is:

value = 2 and list[5] = {3, 1, 5, 7, 9};
