In the game of scrabble, each player begins by drawing 7 tiles from a bag containing 100 tiles. there are 42 vowels, 56 consonants, and 2 blank tiles in the bag. cait chooses her 7 tiles and is surprised to discover that all of them are vowels. we can use a simulation to see if this result is likely to happen by chance. in 1000 repetitions of the simulation, there were 2 times when all 7 tiles were vowels. what conclusion would you draw?

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

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).
