Answer:
You would expect for 35 people to have consumed alcoholic beverages.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they consumed alcoholic beverages, or they did not. The probability of a person having consumed alcoholic beverage is independent of any other person. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
We learned in Exercise 3.25 that about 70% of 18-20 year olds consumed alcoholic beverages in 2008.
This means that 
We now consider a random sample of fifty 18-20 year olds.
This means that 
How many people would you expect to have consumed alcoholic beverages
You would expect for 35 people to have consumed alcoholic beverages.
Answer:
152
Step-by-step explanation:
Given the function :
C(x)=−15x+2304
The least Number of items, x that can be produced so that average cost does not exceed $33
C(x) = less than or equal to 33
33 = - 15x + 2304
33 - 2304 = - 15x
-2271 = - 15x
x = 2271 / 15
x = 151. 4
Hence, the least number of items that can be produced is 152
6x is the answer for the question
The system of equations has infinitely many solutions
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x + 3y = 12 ------- eqn 1
y = x + 4 --------- eqn 2
We have to find the solution to the system of equations
We can use substitution method
Substitute eqn 2 in eqn 1
-3x + 3(x + 4) = 12
-3x + 3x + 12 = 12
-3x + 12 = -3x + 12
If we have terms with same terms on both sides of equal sign, then we have infinitely many solutions
Thus the system of equations has infinitely many solutions
Answer:
-5,5
