Answer:
B) 0.287
Step-by-step explanation:
For each Coffeeton resident, there are only two possible outcomes. Either they recognize the brand name, or they do not. The probability of a resident recognizing the brand name is independent of other residents. So we use the binomial probability distribution 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.
53% recognition rate in the town of Coffeeton.
This means that 
Find the probability that exactly 4 of the 7 Coffeeton residents recognize the brand name.
This is P(X = 4) when n = 7. So
So the anwer is:
B) 0.287
Answer and Step-by-step explanation:
<u>Add together the hours, then divide the amount earned by the total amount of hours.</u>
<u />
3 + 5 = 8
105 ÷ 8 = <u>$13.125 (which would round up to 13.13) [About $13.13] is earned per hour.</u>

If you divide the fraction you will see
Answer:
16>2.3b
Step-by-step explanation:
1.5+0.8=2.3
Substitute b as 1. Which would still keep it as 2.3.
Given :
Raffle tickets were sold for a school fundraiser to parents, teachers, and students. 563 tickets were sold to teachers. 888 more tickets were sold to students than to teachers. 904 tickets were sold to parents.
To Find :
How many tickets were sold to students.
Solution :
Ticket sold to teachers, T = 563 .
Ticket sold to parents, P = 904 .
Let, ticket sold to students are S.
Now, it is given that :
S = T + 904
S = 563 + 904
S = 1467 students
Therefore, tickets sold to students are 1467 .
Hence, this is the required solution.
