Answer:
So the answer for this case would be n=737 rounded up to the nearest integer
Step-by-step explanation:
We have the following info given:
the sample mean
the sample deviation
represent the sample size
The degrees of freedom are given by:

The margin of error is given by this formula:
(a)
And on this case we have that ME =0.25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(5)
The confidence level is 95% and the critical value for this case would be given by
, replacing into formula (5) we got:
So the answer for this case would be n=737 rounded up to the nearest integer
Let's assume a the age of Joe
b the age of James
a=b+10 (1)
2*(a+8)=3(b+8) (2)
==> 2*(b+10+8)=3b+24
==>2b+36=3b+24
==>b=12
==>a=12+10=22
Joe is 22 years's old
James is 12 years's old.

Answer:
1/9, 2/8, 3/7, 4/6
Step-by-step explanation:
The fraction will be proper when the numerator is less than the denominator. That means numerators can be less than 10/2 = 5. The fractions that satisfy the requirement are ...
1/9, 2/8, 3/7, 4/6
Those with even numerators can be reduced. So the reduced fractions are ...
1/9, 3/7
