Answer:
The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Add some parenthesis any where you like!.
The Commutative property states that order does not matter. Multiplication and addition are commutative.

Answer:
46.08 students said that chicken is their favorite food.
Step-by-step explanation:
Let <em>X </em>denote the number of students who liked chicken.
The proportion of students who liked chicken is, <em>p</em> = 0.08.
About <em>n</em> = 576 students were surveyed about their favorite food.
Every student's answer was independent of the others.
Thus, the random variable <em>X</em> follows a binomial distribution with parameters <em>n</em> = 576 and <em>p</em> = 0.08.
The probability mass function of <em>X</em> is:
Then expected number of students who said that chicken is their favorite food is:
Thus, 46.08 students said that chicken is their favorite food.
Answer:
The best estimate for the solution of the system of equations is the ordered pair (7, 0.5)
Step-by-step explanation:
The way to solve this problem is to take a deep look into the picture, where we can see that the interception between the lines occurs right in x=7. thus, eliminating the first choice.
Next, we can see that the interception is somewhere far from the 'x' axis, hence 'y' variable can not be zero in this point.
Thus, we have our possible solution, without knowing anything else, the ordered pair (7, 0.5).
Remember, a system of equation has a solution when an interception occurs between its equations
