Answer:
Roughly 16 million bacteria.
Step-by-step explanation:
Multiply the rate of the bacteria going through mitosis times the amount of daughter cells per hour, for this case.
<em>r x (m)ms x hr</em> <em>= </em>bacteria in one day
Hope this helps!
<em>note: ms and hr are millisecond and hour</em>
Answer:

Step-by-step explanation:
Answer: 9/17
Reason
The reciprocal is simply flipping the denominator and numerator of a fraction.
1-8/9 as a mixed fraction is 17/9
So the reciprocal would be to flip it,
Giving you 9/17 which is in its simplest form
Answer: 2172
Step-by-step explanation:
Formula to find the sample size n , if the prior estimate of the population proportion(p) is known:
, where E= margin of error and z* = Critical z-value.
Let p be the population proportion of adults have consulted fortune tellers.
As per given , we have
p= 0.20
E= 0.02
From z-table , the z-value corresponding to 98% confidence interval = z*=2.33
Then, the required sample size will be :
Hence, the required sample size = 2172
