Answer:
C) 0.45
Step-by-step explanation:
Given that a population mean is 0.45, standard deviation is 0.001 and margin of error stands at 0.5% we have the following
0.45 + 0.001 = 0.451
Population mean with standard deviation is 0.451.
0.451 * 0.5% = 0.448745
We now reduce the number to two decimals and get the final marigin of error
0.45 as result

Answer:

Step-by-step explanation:
If x varies directly as the product of p and m, and inversely with y, the relation can be written ...
x = k(pm)/y . . . . where k is the constant of proportionality
__
This can be solved for k:
k = xy/pm
For the given values, the value of k is ...
k = (2)(4)/((0.5)(2)) = 8
Then the relation between the variables can be written ...
(xy)/(pm) = 8
