Answer:
B. volunteer bias.
Explanation:
-Experimenter bias is when the expectations of the experimenter in regards to the outcome are communicated to the participants in any form.
-Volunteer bias refers to a situation in which the people that volunteer to take place in a study doesn't represent the general public.
-Research bias is when the experimenter influence the result to get a specific outcome.
-Social desirability bias is when the people taking part in a study give their responses in a way that is viewed as favorable.
According to this, the answer is that the situation would be an example of volunteer bias.

Explanation:
Required
Express to execute a while loop with the given condition.
The condition in the question is that: the user input must be greater than or equal to 0.
The statement for this is:
( 
) { 
}
Where num is the input variable
Answer:
Float circumference; // Create a float variable
Explanation:
The float datatype is used for storing the decimal point values .The syntax to declaring any float variable is given below.
float variable-name;
float circumference; // create a float variable
circumference=89.9007;; // store the value in circumference
Following are program in c++
#include <iostream> // header file
using namespace std; //namespace
int main() // main function
{
float circumference; // creating variable float
circumference=89.9007; // storing value
cout<<circumference; // display value circumference
return 0;
}
Output:
89.9007
Answer: You would need two loops to iterate through both dimensions
Explanation:
matrix = [[1,2,3,4,5],
[6,7,8,9,10],
[11,12,13,14,15]]
for rows in matrix:
for numbers in rows:
print(numbers)
The first loop cycles through all the immediate subjects in it, which are the three lists. The second loop calls the for loop variable and iterates through each individual subject because they are lists. So the first loop iterates through the 1st dimension (the lists) and the seconds loop iterates through the 2nd dimension (the numbers in the lists).
