A.) 7^4x = 10
log base 10 (7^4X) = log base 10 (10)
4x log base 10 (7) = 1
4x (0.8451) = 1
3.3804x = 1
x = 0.2958
b.) ln(2) + ln(4x-1) = 5
ln (2 * 4x-1) = 5
ln (8x-2) = 5
log base (3) (8x-2) = 5
e^5 = 8x-2
e^5+2 = 8x
x = 18.8016
Answer:
4 / 9
Step-by-step explanation:
Solution:-
- Michael bus rental agency has a total of n = 18 buses.
- Out all the available buses he has r = 8 buses with AC in them.
- If we were to randomly select a bus from his agency what is the probability that the bus would have an AC:
P ( Bus with AC ) = Favorable Outcomes / Total outcomes
= Number of bus with AC / Total Buses
= r / n
= 8 / 18
= 4 / 9
