Step-by-step explanation:
214x12=2568
Divide the y-value by the x-value.
(1/2) / (2/5) = 1/2 x 5/2 = 5/4

Step-by-step explanation:
So 10% said they lived in city
60 said they lived in city
60=10%
remember that 100%=all
60=10%
remember th fact that 10 times 10=100
60 times 10=10 times 10%
600=100%
600 people surveyed
It has been given that exactly 0.1 of the radioactive nuclei in a sample decay each hour. Thus, after n hours, the fraction of nuclei is given by the model expression: .
Now, to find the value of n equal to one half-life, all that we need to do is to equate the above expression to half or 0.500 (to the indicated places of decimal) and solve for n.
Thus, we will get:
Taking the log to the base 10 on both sides, we get: (Please note that we can take the log to any base)
Dividing both sides by log(0.900), we get:
hours
Therefore the value of n equal to one half-life is 6.579 hours.
