Answer:

$3 for 1 book

Step-by-step explanation:

if 3 books are $9, then to find out how much only one of them costs you have to divide the money by the number of things you're buying. So if you divide 9 by 3 you get 3, so 1 book costs $3.

This also checks because if you buy one book for $3 but want to buy 3 books, you have to pay thrice the amount for the books, so you would have to pay $9 because 3 times 3 is 9

lozanna [386]

Answer:

12.37

Step-by-step explanation:

I attached a picture of the work but a few notes on it

1. I did use a calculator for the square root

2. the square root symbol was in the way and a bit distracting  so I had to drop it (temporarily) but to do that I squared both sides but that's kinda optional. and I wrote it on the paper

Suppose there is no outcome common to all three of the events A, B, and C.
mina [271]

Answer:

Yes, the event are mutually exclusive...

Step-by-step explanation:

Event are mutually exclusive if those event cannot occur at the same time. That is the definition of mutually exclusive for instance in a football match, a certain team canot score 0 and 2goals in a match, it is either he scored 2goals or zero goals... In a throw of a coin we cannot have head and tail at the same time, it is either we have a head or a tail, all the event are mutually exclusive.

Now if we have a dealer selling blue car and two doors car. Let say 20% are blue and 10% have two doors. Then, this are not mutually exclusive because we can have a car that is blue and have two doors.

Mutually exclusive events are like disjoint set in SET theory, where A intersection B intersection C is equal to empty set.

Where A n B n C= {} empty set

How do I find the horizontal asymptote of h(x)=x+6/x^2-64 ?
SashulF [63]

I assume the equation described is:

( x + 6 ) / ( x^2 - 64 )

You can compare the degree of the numerator and denominator in a function that takes the form of this type of rational equation.

Here are the three rules

#1 (Correct Answer): When the degree of the numerator is smaller then the denominator the horizontal asymptote is y = 0

#2 If the degree of the numerator and denominator is the same, then you take the leading coefficient of the numerator (n) and denominator (d) to create the answer y = n / d in this equations case it would be 1 / 1 since variables technically have an invisible 1 in front of them since anything multiplied by 1 is its self, 1x = x

#3 When the degree of the numerator is greater then the degree of the denominator then this means that it does not have a horizontal asymptote.

Again the final answer is that the horizontal asymptote is y = 0
