Answer:
$2.65
Step-by-step explanation:
to get a weighted mean
divide the total revenue by the number of books
Revenue
(1.55 * 40) + (4.85 * 20)
$159
weighted mean
159/60
$2.65
Answer:
Choice C

Step-by-step explanation:
The quadrant in which an angle lies determines the signs of the trigonometric functions sin, cos and tan
If an angle Θ lies in quadrant IV, cos(Θ) is positive and both sin(Θ) and tan(Θ) are negative
Two of the trigonometric identities we can use are
1.
and
2. 
Using identity 1, we can solve for cos(s) and cos(t)


Since both angles lie in quadrant IV, both cos(s) and cos(t) must be positive so we only consider the positive signs of both values
Using identity 2, we can solve for cos(s-t)

Multiplying numerator and denominator of the first term by
gives us the final expression as
