Answer:

And the value for n rounded up would be n = 174
Step-by-step explanation:
We have the following info given:
previous estimation for the deviation
the margin of error desired
represent the confidence
The Margin of error is given by:

If we solve for the value of n we got:

For this problem we know that the confidence is 98% so then the significance level would be
and the critical value would be:

And replacing we got:

And the value for n rounded up would be n = 174
Both angles have to be 90 so if you find the value for x for one you get the other one ahmatically answer is 22 btw :)

Can l get sum more deatal
Step-by-step explanation:
The task consists it form ordered pairs, this is pairs of this form (x,y) where the two numbers are paired because some relation.
In this case the relations is the " in month x it had a profit y"
Then the ordered pairs are: (April, 2000) , (May, 3000), (June, 5000).
If you use the number of the month to identifiy it, then you can write the ordered pairs as:
(4,2000), (5,3000), (6,5000)
Both ways are correct forms of ordered pairs.
