Answer:
And rounded up we have that n=8068
Step-by-step explanation:
The margin of error for the proportion interval is given by this:
(a)
We want for this case a 95% of confidence desired, our significance level would be given by
and
. And the critical value would be given by:
The margin of error for this case is
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The estimated proportion for this case is
. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=8068
Answer:
Step-by-step explanation:
Finding the domain:
The domain of a function is the set of possible input values for which the function is real and defined.
Given the function

The function has no undefined points nor domain constraints. Hence, the domain is

i.e.

Finding the range:
The range of a function is the set of possible output values (dependent variable y values) for which a function is defined.
The range of polynomials with odd degree is all the real numbers.
Hence, the domain is

i.e.

2/x ^6-3 you do the opposite of everything
Answer:
9/32
Step-by-step explanation:
3 5/9
=> (27+5)/9
=> 32/9
Reciprocal of 32/9 is,
=> 9/32
