Swap the domain and range from the original question
The first digit could be any of these: 1, 2, 3, 4, 5, 6, 7, 8, 9
There are 9 choices, and only one is 1, so, the probability is 1/9
The second digit could be these(because the number is even): 2, 4, 6, 8
There are 4 choices, and only one is 8, so the probability is 1/4
Multiply the fractions:
1/9*1/4=1/36
The probability of his house number being 18 is 1/36
Good luck!
Answer is C hope this helps
She should have
nickles: 6 . =30
dimes: 30 . = 300
=330 . or $3.30
x is the number od doubling periods ( which is given as every 7 years)
28 years / 7 = 4 doubling periods in 28 years
so x = 4
so you now have:
f(x) = 8000 * 2^4
2^4 = 16
so 8000 * 16 = $128,000 would be the answer
