chromosomes are of two in human x and y but the mother has only x chromosomes when xand x meet then baby girl is born and when x and y meet then baby boy is born.Genes is the properties which are present in all living organisms.The full form of DNA is deoxy ribonucleic acid.It is the properties which carries the similarities of both mother and father to a new generation.
Answer:
26.6 mi^2
Step-by-step explanation:
Answer:
X = 55
Step-by-step explanation:
If the angel is 90:
75 + 90 = 165
165 divided by 3 = 55
Answer:
36.58% probability that one of the devices fail
Step-by-step explanation:
For each device, there are only two possible outcomes. Either it fails, or it does not fail. The probability of a device failling is independent of other devices. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
A total of 15 devices will be used.
This means that 
Assume that each device has a probability of 0.05 of failure during the course of the monitoring period.
This means that 
What is the probability that one of the devices fail?
This is 


36.58% probability that one of the devices fail
