Answer:
a) $1056.33 b) 23 years
Step-by-step explanation:
a) 10000(1+1.85/100)^3=10565.33 (2d.p.)
b) let x be the no. of years
15000 = 10000(1+1.85/100)^x
1.5 = 1.0185^x
ln both sides
ln 1.5 = x ln 1.0185
x = ln 1.5/ln 1.0185
=22.11
=23 years (rounded up)
The average is (0.76+0.88) / 2 = 1.64 / 2 = 0.82
Answer:
1/24
Step-by-step explanation:
This is a mutually exclusive event.
There are four possible floors and four people.
The probability that the first floor is selected is 1/4
The same probability exists for the second floor and the third and the fourth.
So, the probability of all four people choosing different floors is 1/4 * 1/4 * 1/4 * 1/4 = 1/24
