Original Price
-------------------------------------------------------
Original Price = $325.50
-------------------------------------------------------
Discount
-------------------------------------------------------
Discount = 30%
Discount = 0.3 x 325.5 = $97.65
-------------------------------------------------------
Selling Price
-------------------------------------------------------
Selling Price = $325.50 - $97.65
Selling Price = $227.85
-------------------------------------------------------
Answer: $227.85

Answer: (-infty, infty)
Step-by-step explanation:
The domain of a quadratic function is the set of real numbers.
Answer:
The greatest number of the books that could have been borrowed during the week is 36
Step-by-step explanation:
Let's create an equation which represent this problem, where will rest the book borrow and add the book returned to the 40 initial amount of book on Monday, to get the 22 book in the shelf on Saturday morning
40 (book on the shelf on Monday) - x (book borrowed) + 0.5 * x (50 % of the book was returned before Saturday) = 22 (books in the shelf on Saturday morning)
40 - x + 0.5 * x = 22
40 - 0.5*x = 22
18 = 0.5 * x
18/0.5 = x
36 = x
The amount of borrowed books is 36
A binomial is an expression that has two terms.
(1) Has a single term
(2) Has two terms
(3) Has three terms
(4) Has a single term
So the only binomial out of the answers is (3)
Answer:
•Lower confidence limit = $155.2109
•Upper confidence limit ,= $174.5891
Step-by-step explanation:
We are given:
U = 17
x' = $165.40
S.d = $21.70
a = 10℅ (90℅ confidence interval)
For s.d(x'), we have:
S/√u = 
= 5.2630
Therefore, S.E (x') = $5.2630
At a= 0.10 (90℅ confidence level)
and degree of freedom = 16 (17-1)
90℅ confidence interval all around sample mean, will be:
(x' ± 
; a S.E (x')
= (165.4±(174.6)(5.2630)
(165.5±9.189)
($156.2109, $175.5891)
