Ok pretty sure the probability of a 5 is 1/5
The probability of a # greater than 3 is 2/5
And the probability of a 2 or 5 is 2/5
(1/5 is 20% and 2/5 is 40% if you need those)
Well, minusing 8 from every t just moved theh function to the right 8 units
it had no effect on the number of t intercepts (horizontal is t axis instaead of x axis)
originally, it has 1 t intercept at t=0
now it still has 1 t intercept, but now it is at t=8
100 < 50(1.12)t
2 < (1.12)t
ln 2 < t ln (1.12)
0.6931 < t(0.1133)
6.117 < t
I'm pretty sure the answer is D, if not C.
