Answer:
B. global
Explanation:
A global variable lives on even when a function returns.
Answer:
The answer is "Option A".
Explanation:
In the given code an integer array "x" is defined, that stores some elements and another integer variable "a" is declared, that holds a value that is "10". In this code a conditional statement is defined, which checks array element value, in if block element of array that position is 2 is greater then the element of array that position is 5.if this condition is true, so variable a value is change that is equal to 5. In else block if the above condition is not true so the value of a variable is equal to 8, and another options is wrong that can be described as follows:
- In option B, The given condition is not false, that's why it is not correct.
- In option C, The value of variable a is changed when condition is true or false, that's why it is not correct.
- In option D, It is wrong because we can compare array elements.
By looking at your code, it seems like you're trying to let the user enter positive numbers until the user enters a negative number. To achieve this, you need to indent int(input("Enter a number, negative to stop")) inside the loop.
The second answer choice is correct.
Answer:
4.24
Explanation:
First you find the mean of the data set, which is 7. Then to find standard deviation you have to follow the formula which tells you to subtract the mean from each number under the square root : √(2 - 7)^2 + (9 - 7)^2 + (10 - 7)^2 + (4 - 7)^2 + (8 - 7)^2 + (4 - 7)^2 + (12 - 7). Once you solve the parenthesis you square it, once you square it the negatives won't matter. That will leave you with this : √(25 + 4 + 9 + 9 + 25). The formula tells you to find the sum of those numbers (which is 72) then subtract one from how many numbers there are, 5 - 1 = 4, and divide your sum by that number. So 72 / 4 = 18. Then you find the square root of 18 and that becomes your answer.
