Using a system of equations, it is found that:
- There are 8 chickens in the yard.
- There are 16 pigs in the yard.
-----------------------------------------
This question is solved using a system of equations. I am going to say that:
- x is the number of chickens.
-----------------------------------------
- A chicken has 1 head, as do a pig.
- There are 24 heads.
Thus:
-----------------------------------------
- A chicken has 2 feet.
- A pig has 4 feet.
- In total, there are 80 feet.
Thus:
-----------------------------------------
Number of chicken:
Since 
There are 8 chickens in the yard.
-----------------------------------------
Number of pigs:
There are 16 pigs in the yard.

Answer:
5
Step-by-step explanation:
6 x 3 = 18
90 / 18 = 5
You take 92,000 and times it by 3 then divide by 2. hope this helps :)
Answer: The statements that describe a normal distribution are;
a. The density curve is symmetric and bell-shaped.
b. The normal distribution is a continuous distribution.
Step-by-step explanation: The normal distribution is the most commonly used and important statistic tool. It is referred to as the "Bell Curve" because of its bell-shape and the the fact that it is symmetric density curve. A continuous distribution defines the possibilities of a continuous random variable and a prime example of a continuous distribution is the Normal distribution.
The normal distribution is not a discrete distribution because it does not have discrete variables. The normal distribution is not a flat line that extends from a minimum to a maximum but it is a continuous distribution that extends in a bell shape from one minimum value going up to a maximum value before descending back to another minimum value.
68% of a normal distribution curve falls with one standard deviation from the mean not 32%.
The two parameters that define a normal distribution is the mean and the standard deviation.
Answer: 13
Step-by-step explanation: The range of a group of numbers is the difference between the largest and smallest numbers. First, we can order these numbers from least to greatest.
32 - 33 - 34 - 37 - 40 - 45
Next, we can subtract the smallest number from our largest number.
<u>Smallest number = 32</u>
<u>Largest number = 45</u>
45 - 32 = 13
Therefore, the range of these numbers is 13.
