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:
Let's solve the problem step-by-step:
We are given that the sum of three numbers is 2100. Let's call the first number x and the other two numbers y and z.
From the information given, we know that x = y + z, and y = z (the other two numbers are equal to each other).
Substituting y = z into x = y + z, we have x = 2z.
We are also given that the sum of the three numbers is 2100. So, we can write the equation x + y + z = 2100.
Substituting x = 2z and y = z, we have 2z + z + z = 2100.
Simplifying the equation, we have 4z = 2100.
Dividing both sides of the equation by 4, we find z = 525.
Substituting z = 525 back into y = z, we find y = 525.
Finally, substituting z = 525 and y = 525 back into x = 2z, we find x = 1050.
Therefore, the three numbers are x = 1050, y = 525, and z = 525.
Among the options provided, the correct answer is A) (1050, 525, 525).

The distance between the mountains and her residence is 315 miles.
Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.
Given that Amanda drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 7 hours. when Amanda drove home, there was no traffic and the trip only took 5 hours. if her average rate was 18 miles per hour faster on the trip home.
The distance will be calculated as,
Distance = S x 7
The other distance is,
Distance = 5 ( S + 18 )
7S = 5S + 90
S = 45 miles
Distance = 45 x 7
Distance = 315 miles
