Answer:
85.55
Step-by-step explanation:
i dont know if im right but
1) i took 12 × $6.79 for the total cost ehich totalled out to 81.48
2) i used calcutator.net and put in the sales tax 5% ($4.07)
3) it gave me $85.55 after adding the tax
Using the binomial distribution, it is found that there is a 0.0231 = 2.31% probability that the first person to say yes will occur with the seventh customer.
For each person, there are only two possible outcomes, either they say yes, or they say no. The probability of a person saying yes is independent of any other person, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- The probability that the seventh person is the first to say yes is P(X = 0) when n = 6(first six say no) multiplied by 0.37(probability the seventh say yes).
- 37% say yes, hence
Then:
0.0231 = 2.31% probability that the first person to say yes will occur with the seventh customer.

Answer:
The average score is 73
Step-by-step explanation:
Your average score is the sum of each of your tests scores multiplied by the weight of the test.
We have that:
You scored 90 on the midterm
The midterm is worth 30%
You scored 60 on the final
The final is worth 50%
You scored 80 on the class project
The class project is 20%
Average score:
A = 90*0.3 + 60*0.5 + 80*0.2 = 73
Answer:6.5%

Answer:
Option C - Perfect square trinomial.
Step-by-step explanation:
Given : Polynomial
To find : What pattern is represented by the polynomial?
Solution :
First we make the polynomial in factor form,
Polynomial
Since, it is not factor clearly so try to make the square.
Taking 4 common,
Identifying the x and y terms in the identity,
Factor the perfect square trinomial,
Therefore, The pattern polynomial represent is perfect square trinomial.
So, Option C is correct.
