Answer:

The confidence level is 0.98 and the significance is
and
and the critical value using the table is:

And replacing we got:

Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
the sample size
represent the sample mean
We want to find the margin of error for the confidence interval for the population mean and we know that is given by:

The confidence level is 0.98 and the significance is
and
and the critical value using the table is:

And replacing we got:

Answer:2
Step-by-step explanation:
So you're gonna take add 1 to both sides and add aw to both sides also
y+1=2w+aw
then you factorize the w
y+1=w(2+a)
divide 2+a in both sides
y+1/2+a=w
the answer is
y+1/2+a=w
Answer:
={6,7,8,9,10}.
Step-by-step explanation:
We have an empty set: M={} and the set N={6,7,8,9,10}.
The union of these two sets are elements in M or N or both.
Since the M is a null set, 
Therefore:
={6,7,8,9,10}.
The union for the given sets is {6,7,8,9,10}.
