Ellen wants to purchase a book that is regularly priced at $18. The book is discounted 15%. She also needs to pay a 6% sales tax on the discounted price.
What is the total amount Ellen will pay for the book?
Answer:
$16.22
Step-by-step explanation:
When 18 dollars is discounted by 15%, we first need to find what 15% of 18 is. 18 times .15 is 2.7, and 18-2.7 is 15.3.
Then, we need to find the sales tax, which applies to the discounted price. 15.3 times 0.06 is 0.918. Add that to 15.3 and you get 16.218, or about $16.22. Hope this helped! :D

Which system of equations is represented by lines s and t?
Answer:
a
Step-by-step explanation:
The system of equations is represented by lines s and t will be,3x + 5y = - 18 and 5x - 9y = 25.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
For S,
x ⇒ -5 2 4
y ⇒ 4 10 22
For T,
x⇒ -4 0 5
y⇒ 14 6 -4
Since the equation represented by lines s and t will be verified by the given value for the x and y.As a result, the equation given in option C satisfies all the given points.
Thus, the system of equations is represented by lines s and t will be,3x + 5y = - 18 and 5x - 9y = 25.

What is the product of (3a + 2)(4a2 – 2a + 9)? 12a3 − 2a + 18 12a3 + 6a + 9 12a3 − 6a2 + 23a + 18 12a3 + 2a2 + 23a + 18
Answer:
12a3 + 2a2 + 23a + 18
Step-by-step explanation:
Vertical multiplication works well when you have a binomial times a trinomial.
Multiply 2 times the trinomial and get 8a2 - 4a + 18 then multiply 3a times the trinomial to get 12a3. -6a2 + 27a
Then combine like terms.
The product of the givens expressions is 12a³ + 2a² + 23a + 18.
Product of the given expressionsThe product of the givens expressions is obtained by multiplying all the variables in the bracket as shown below.
(3a + 2)(4a² – 2a + 9) = 3a(4a² – 2a + 9) + 2(4a² – 2a + 9)
= 12a³ - 6a² + 27a + 8a² - 4a + 18
simplify by collecting similar terms together
= 12a³ + 2a² + 23a + 18
Thus, the product of the givens expressions is 12a³ + 2a² + 23a + 18.

∠2 = 75
Step-by-step explanation:
In the given triangle two sides are equal and so it is an isosceles triangle. So, the angles opposite to equal sides are equal
11x + 9 + 11x + 9 + 30 = 180 {Angle sum property of triangle}
11x + 11x + 9 +9 +30 = 180
22x + 48 = 180
22x = 180 - 48
22x = 132
x = 132/22
x = 6
∠2 = 11*6 + 9 = 66 +9 = 75
Solve for x.

x=16/3
Step-by-step explanation:
5x−2(x+1)=14
Distribute
5x -2x -2 =14
Combine like terms
3x -2 =14
Add 2 to each side
3x-2+2 =14+2
3x=16
Divide each side by 3
3x/3 = 16/3
x=16/3
Answer:
x = 16/3
Step-by-step explanation:
5x - 2(x + 1) = 14
~Simplify
5x - 2x - 2 = 14
~Combine like terms
3x - 2 = 14
~Add 2 to both sides
3x = 16
~Divide 3 to both sides
x = 16/3

When Val checks her cable bill, she is shocked by her movie-rental bill for the month. Renting movies costs $2.99 for each movie. She could pay $7.99 a month that allows her to watch unlimited movies, but she doesn't have a lot of time to watch movies and she doesn't want to waste her money if it's not worth it. She creates the following probability distribution for the number of movies she typically watches each month: Should Val buy the monthly plan for unlimited movies or should she continue to pay $2.99 per movie? Explain your choice thoroughly. *
Answer:
She should buy the monthly plan for the unlimited movies rather than pay $2.99 per movie. This is because, the more she pay that amount for each movie, the higher her expenses would become at the end of each month.
For example, let assume, in a month, she 8 free days (Saturday and Sunday). She paying for each movie each of those days would supersede the amount she could have spent assuming she did the unlimited monthly plan of $7.99.
That notwithstanding other days which will feel like watching movies or the public holidays which she would be free to relax.

Find P(3) when µ = 4
there wasn't any prior information.
It was added
====================================================
Explanation:
The Poisson PDF value is given by the function
P(x) = ( e^(-mu)*mu^x )/(x!)
where the exclamation mark indicates a factorial
In this case, mu = 4, so we can update the equation into
P(x) = ( e^(-4)*4^x )/(x!)
Now plug in x = 3 to finish off the problem
P(x) = ( e^(-4)*4^x )/(x!)
P(3) = ( e^(-4)*4^3 )/(3!)
P(3) = 0.1953668148129
P(3) = 0.20

How would knowing the type of symmetry help you graph a function?
A graph is said to be symmetric about the y -axis if whenever (a,b) is on the graph then so is (−a,b) . Here is a sketch of a graph that is symmetric about the y -axis. A graph is said to be symmetric about the origin if whenever (a,b) is on the graph then so is (−a,−b) .
hope this helped u <3
Answer: How do you describe the symmetry?
If f (-x), then the graph of f(x) is symmetrical with respect to. A function symmetrical with respect to the y-axis is called an even function. A function that is symmetrical with respect to the origin is called an odd function.
