Answer:
Hour 3
4 * 2 = 8
Hour 4
8 * 2 = 16
Hour 6
32 * 2 = 64
Hour 7
64 * 2 = 128
Hour 12
2048 * 2 = 4096
Step-by-step explanation:
We are told that initially there is a bacterium that doubles every hour, so let's calculate what happens in the first 12 hours every hour.
Hour 0
one
Hour 1
1 * 2 = 2
Hour 2
2 * 2 = 4
Hour 3
4 * 2 = 8
Hour 4
8 * 2 = 16
Hour 5
16 * 2 = 32
Hour 6
32 * 2 = 64
Hour 7
64 * 2 = 128
Hour 8
128 * 2 = 256
Hour 9
256 * 2 = 512
Hour 10
512 * 2 = 1024
Hour 11
1024 * 2 = 2048
Hour 12
2048 * 2 = 4096
We can deduce that the growth of the bacteria is:
2 ^ n
where n is the # of time that has passed
Answer:
Step-by-step explanation:
a) No of outcomes= 7
total no of outcomes= 10
probability = no of outcomes/total no of outcomes
=7/10
b) 4/10 ( since the outcomes could be 1,2,3,4)
c) no 1 to 10 has 5 odd numbers
so, probability = 5/10 = 1/2
d) multiples of 3 from 1 to 10 are :-
3,6,9= 3 no's
so probability = 3/10
He would have to take out at least 16 coins.
Taking any less could result in having fewer quarters since even 15 could result in <span>12 dimes and 3 quarters. This way it will always be at least 4 quarters.</span>
