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 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
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".learn more on python here: https://brainly.com/question/13437928

negative interrogative simple sentence9.11: Array Expander
Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is twice the size of the argument array. The function should copy the contents of the argument array to the new array, and initialize the unused elements of the second array with 0. The function should return a pointer to the new array. Demonstrate the function by using it in a main program that reads an integer N (that is not more than 50) from standard input and then reads N integers from a file named data into an array. The program then passes the array to your array expander function, and prints the values of the new expanded array on standard output, one value per line. You may assume that the file data has at least N values.
Prompts And Output Labels. There are no prompts for the integer and no labels for the reversed array that is printed out.
Input Validation. If the integer read in from standard input exceeds 50 or is less than 0 the program terminates silently.

You have been asked to write a loop that outputs values in a database column ranging between 10 and 100. Any number that is not divisible by 5, and any value that is not an integer, should be ignored. When the value in the loop hits 95, break the loop prematurely. One of your team members has advised the use of break, continue, and pass statements.
Answers
Explanation:
This is going to depend on the language you're working in heavily.
First you will want to verify your number is an integer rather than a floating point which will completely depend on the language and whether you care if the floating point is 1.0 for example, which could still be converted a valid integer value.
After you've determined if it is an integer you can use modulo to check if the integer is evenly divisible by 5. In C-like languages you would write this as `x % 5`. Any result other than zero would mean it is not evenly divisible.
You also need to check if the integer is >= 10 and <= 100.
Read up on for/while loops and break/continue in those loops to understand that concept, it is pretty universal to all languages.

12.2 E-Z LOAN
A loan obtained from a lending institution is typically paid off over time using equal monthly payments over a term of many months. For each payment, a portion goes toward interest and the remaining amount is deducted from the balance. This process is repeated until the balance is zero. Interest is calculated by multiplying the current balance by the monthly interest rate, which is usually expressed in terms of an Annual Percentage Rate (APR). This process produces an Amortization Schedule where the amount applied to interest is gradually reduced each month and the amount applied to the balance grows. For example, the following amortization schedule is for a loan of $ 10.000 at an APR of 3.9% over a term of 30 months:3 will match months 12, 24, and 30 respectively.
Answers
Following an amortization schedule, the monthly payments will be $350.39 and the total payment in 30 months will be $10511.7.
How much should be paid monthly to complete loan payment in 30 months?The loan payment follows an amortization schedule where the amount applied to interest is gradually reduced each month and the amount applied to the balance grows.
The amounts to be paid is calculated using the amortization formula:
P = a ÷ {{[(1 + r/n)^nt] - 1} ÷ [r/n(1 + r/n)^nt]}where
P is monthly paymenta is credit amountr is the interest ratet is the time in yearsn is number of times the interest is compoundedFor the loan of $10000;
a = $10000r = 3.9% = 0.039nt = 30 monthsHence,
P = $10000 ÷ {{[(1 + 0.039/12)^60] - 1} ÷ [0.039/12(1 + 0.0.039/12)^60]}
P = $350.39 per month
Total payment in 30 months = $350.39 × 30 = $10511.7
Therefore, the monthly payments will be $350.39 and the total payment in 30 months will be $10511.7.

Write a value-returning function that receives an array of integer values and the array size as parameters and returns a count of the number of elements that are less than 60.
Answers
Answer:
The c++ function for reversing an array is given. The function is declared void since it returns no value.
void reverse( int arr[], int len )
{
int temp[len];
for( int k = 0; k < len; k++ )
{
temp[k] = arr[k];
}
for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )
{
arr[k] = temp[j];
}
}
Explanation:
The reverse function uses another array to reverse the elements of the original array.
An integer array is declared, temp[len], having the same length as the input array.
int temp[len];
To begin with, the elements of the input array are copied in the temp array.
for(int k = 0; k < len; k++ )
{
temp[k] = arr[k];
}
Next, the elements of the input array are given new value.
The temp array, in reverse order, is copied into the input array.
for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )
{
arr[k] = temp[j];
}
The above for loop makes use of two variables simultaneously.
While the array, arr is proceeding from first element to the next, the array temp begins with the last element and goes down to the previous element.
Now, the input array, arr, contains the elements in reverse order.
The complete program is given.
#include <iostream>
using namespace std;
void reverse( int arr[], int len );
void reverse( int arr[], int len )
{
int temp[len];
for(int k = 0; k < len; k++ )

temp[k] = arr[k];
}
for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )
{
arr[k] = temp[j];
}
}
int main()
{
int len = 5;
int arri[len];
for( int l = 0; l < len; l++ )
{
arri[l] = l;
