Which function represents the graph of f(x)=|x+2| after it is translated 4 units to the right?
1 answer:
Answer:
Step-by-step explanation:
The vertex form of an absolute function is
.... (1)
where, (h,k) is vertex.
The given function is
The vertex of the function is (-2,0).
It is given that graph of f(x) is translated 4 units to the right. So, the vertex of the function after translation is (2,0).
Substitute h=2 and k=0 in function (1).
Therefore, the required function is .

Answer:
0.82 = 82% probability that at least one party will not order drinks
Step-by-step explanation:
For each party, there are only two possible outcomes. Either they will order drinks with their meal, or they will not. The probability of a party ordering drinks with their meal is independent of other parties. So the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
When Ryan is serving at a restaurant, there is a 0.75 probability that each party will order drinks with their meal.
This means that
During one hour, Ryan served 6 parties. Assuming that each party is equally likely to order drinks, what is the probability that at least one party will not order drinks?
6 parties, so n = 6.
Either all parties will order drinks, or at least one will not. The sum of the probabilities of these events is decimal 1. So
We want P(X < 6). So
In which
0.82 = 82% probability that at least one party will not order drinks
