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:
37,000
Step-by-step explanation:
10,867 rounds to 11,000 and 26,186 to 26,000. 11,000 + 26,000 = 37,000

Answer:
Step-by-step explanation:
In order to solve for "x", we must remember the following properties:
- The Subtraction property of Equality states that:
If , then
- The Division property of Equality states that:
If , then
Therefore, knowing these properties, we can solve for "x" to find its value.
First, we need to subtract from both sides of the equation. Then:
And finally, we can divide both sides of the equation by 6. Then we get:
