Suppose you randomly draw a single card from a standard deck of cards.
a) What's the probability you will draw a six of diamonds?
b) What's the probability you will draw a club?
c) What's the probability you will draw a face card?
d) What's the probability you will draw a red card?

Step-by-step explanation:

a. p=1/52

b. P=13/52=1/4

c. P=16/52=4/13

d.  P=26/52=1/2

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

a≈380.13mi² would be your answer if the radius was 11 miles
