Calculate for the mean/ average of the given numbers:
μ = (1 + 2 + 3 + 4 + 5) / 5 = 3
Then, we calculate for the summation of the squares of differences of these numbers from the mean, S
S = (1 - 3)² + (2 - 3)² + (3 - 3)² + (4 - 3)² + (5 - 3)²
S = 10
Divide this summation by the number of items and take the square root of the result to get the standard deviation.
SD = sqrt (10 / 5) = sqrt 2
SD = 1.41
Thus, the standard deviation of the given is equal to 1.41.
25% is also equal to 1/4. One fourth of 8 is 2. Now, check your answer: 2 times 4 is 8. Hope that helps. :)
The answer would be 14...
1 sack = 21 cups.
so 2 sacks would equal 42 cups because 21x2= 42
and it takes 3 cups of flour to make ONE batch of cookies. So 42 divided by 3 is 14. And that’s how you get your answer.
