The number of bags that are probably taken as samples is = 25 bags.
A normal distribution usually appears like a bell shape in a graph whereby the mean is centrally placed.
In the normal distribution of candies per bag;
The standard deviation =3
The mean = 50
Therefore candies per bag = 47 - 53
Using the empirical method, the percentage to the right of the line of normal distribution can be calculated as:
50 + 64/2 = 84%.
That means that 100 - 84 = 16% of the data is below 4.
If 16% = 4
100% =X
Make X the subject of formula,
X = 100× 4/16
X = 400/16
X= 25 bags.
Therefore, the number of bags that are probably taken as samples is = 25 bags.

Answer:
30
Step-by-step explanation:
Square root of a number k will turn it into a number n such that n * n = k.
The square root of 100 is 10 because 10 * 10 = 100, and the square root of 400 because 20 * 20 = 400.
Now, we just need to sum 10 and 20: 10 + 20 = 30.
Thus, the answer is 30.
Hope this helps!
