Chicken A: Standard deviation of A is 4.6 grams; 68% of the eggs fall between 50.9 grams and 60.1 grams.
Chicken B: Standard deviation of B is 4.9 grams; 68% of the eggs fall between 51.9 grams and 61.7 grams.
The difference between the mean weight of Chicken B’s eggs and the mean weight of Chicken A’s eggs to the nearest tenth is...?
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs to the nearest tenth is 1.8 grams.
A normaldistribution is a probability distribution that is symmetric around the mean, with most of the data points falling close to the mean and fewer data points falling farther away from it.
The shape of a normal distribution is often referred to as a bellcurve because when the distribution is graphed, the resulting curve resembles a bell
We have,
Since both datasets follow a normaldistribution, we can use the empirical rule (also known as the 68-95-99.7 rule) to find the mean weight of each chicken's eggs.
For Chicken A, we know that 68% of the eggs fall between 50.9 grams and 60.1 grams. This means that the mean weight of Chicken A's eggs is the average of these two values:
Mean of A = (50.9 + 60.1) / 2 = 55.0 grams
For Chicken B, we know that 68% of the eggs fall between 51.9 grams and 61.7 grams. This means that the mean weight of Chicken B's eggs is the average of these two values:
Mean of B = (51.9 + 61.7) / 2 = 56.8 grams
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs is:
Difference = Mean of B - Mean of A
= 56.8 - 55.0
= 1.8 grams
Therefore,
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs to the nearest tenth is 1.8 grams.

The number of boxes of tiles is 6. The correct option is A.
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called as the area of the circle.
Given that a circular playground for a daycare centre is to be covered with square tiles that are 9 inches on each side. The circle has a diameter of 12 ft. The tiles are packaged in boxes of 25 tiles.
The area of the circle is,
A = π x r²
A = π x 6²
A = 113 square ft
The area in square inches is,
A = 113 x 12 = 1356 square inches
The number of tiles will be,
Number = 1356 / 9
Number = 150
The number of boxes,
N = 150 / 25
N = 6 boxes
Therefore, the number of boxes will be 6.

6+12-20=-2
-2ft
She descends 2ft below ground.
Is there a mistake in the problem?
Answer:
-2 ft
Step-by-step explanation:
So first we do 6 + 12, which is 18, then we do 20 - 18 which is -2. If you dont have an answer like -2 then pick 2 if its a selection.
