Answer:
$54 would 3 quarts of coffee cost
Step-by-step explanation:
Unit rate defined as the rate are expressed as a quantity as 1 such that 3 miles per hour or 5 meter per second.
Use the conversion:
1 ounce = 0.03125 quarts.
As per the statement: An 8 ounce cup of gourmet coffee costs $ 4.50.
Convert 8 ounces in quarts.
1 ounces = 0.03125 quarts
8 ounces = 0.25 quarts.
We have to find the cost for 3 quarts of coffee.
Substitute the given values we have;
Therefore, $54 would 3 quarts of coffee cost.

Answer:
(a) The value of <em>x</em> is 0.30.
(b) The probability that a reported case of rabies is not a raccoon is 0.45.
(c) The probability that a reported case of rabies is either a bat or a fox is 0.15.
Step-by-step explanation:
Denote the events as follows:
<em>R</em> = reported case of rabies is a raccoon
<em>F</em> = reported case of rabies is a fox
<em>B</em> = reported case of rabies is a bat
<em>O</em> = reported case of rabies is a some other animal.
The data provided is:
P (R) = 0.55
P (F) = 0.11
P (B) = 0.04
P (O) = <em>x</em>.
(a)
A property of a probability distribution is that the sum of all individual properties is 1.
That is,
Compute the value of <em>x</em> as follows:
Thus, the value of <em>x</em> is 0.30.
(b)
The probability of the complement of an event is the probability of its not happening.
Compute the probability that a reported case of rabies is not a raccoon as follows:
Thus, the probability that a reported case of rabies is not a raccoon is 0.45.
(c)
Compute the probability that a reported case of rabies is either a bat or a fox as follows:
Thus, the probability that a reported case of rabies is either a bat or a fox is 0.15.

Step-by-step explanation:
arcsin(−1/2) = -arcsin(1/2)
In the table of common values,
-arcsin of 1/2 = π/6 = -π/6
