Answer:
62.29%
Step-by-step explanation:
The probability of Aya being offered a coupon on at least one of the six days she visits the website is 100% minus the probability that she is not offered a coupon on any of the six days, which is described by a binomial probability with zero successes in six trials with a probability of succes p = 0.15.

The probability that Aya will be offered a coupon on at least one of the days she visits the website is 62.29%.
The expression ...
... (x+1)/(x²+2x-24)
will have a zero denominator when
... x² +2x -24 = 0
... (x +6)(x -4) = 0 . . . . . factored form
... x = -6, x = 4 . . . . . . . values of x that make the factors zero
The rational expression will be undefined when x = -6 or x = 4.

Step-by-step explanation:
Answer:
At 2:00 there will be 38,400 bacteria.
Step-by-step explanation:
600/150 = 4
2400/600 = 4
So, the bacteria quadruples every half hour.
At 1:30, there will be 2400*4 = 9600.
At 2:00, there will be 9600*4= 38400
