A long year-end status report for work is 130 pages long. You need to print 17 copies for a meeting next week. How much is the p
Nikitich [7]
The first thing you should do in this case is to know how much paper you need to print for the 17 copies.
 We have then:
 (17) * (130) = 2210
 Then, you must calculate the number of reams you need:
 n = (2210) / (500) = 4.42
 You need 4 full reams and 42% of a fifth ream. So, the cost will be
 C = (4.42) * (3.44) = 15.2048 $
 The unit cost of each paper is:
 Cu = (15.2048) / (2210) = 0.00688 $
 answer
 the paper is going to cost 0.00688 $ for those reports

Samples of rejuvenated mitochondria are mutated (defective) in 3% of cases. Suppose 15 samples are studied, and they can be cons
stiks02 [169]

Answer:

C) At most one sample is mutated

Step-by-step explanation:

If there are 15 samples, it means that 15 is the total (100%) of samples. Then, if we know that there is a chance that 3% are mutated, then we calculate the 3% of 15:

Mutated= \frac{3. 15}{100} = 0.45

This means that at most one sample is mutated, as this result is not zero (we discard answer A), and 0.45 is not more than half of the samples.
