In this question, it is given that
A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.
And we have to find number of bacterias on day *.
For that we use the following formula
Substituting these values in the formula, we will get
THerefore on day 8, number of bacterias are 1579.
Answer:
0.1151
Step-by-step explanation:
Given that a laptop company claims up to 10.1 hours of wireless web usage for its newest laptop battery life. However, reviews on this laptop shows many complaints about low battery life. A survey on battery life reported by customers shows that it follows a normal distribution with mean 9.5 hours and standard deviation 30 minutes.
If X is the battery life then X is N(9.5, 0.5)
(we convert into one unit for calculations purpose here hours)
a) the probability that the battery life is at least 10.1 hours
=
we get the probability that the battery life is at least 10.1 hours is 0.1151
