bearing in mind that, the geometric sequence is "convergent" only when |r|<1, or namely "r" is a fraction between 0 and 1.
Is there any graph to this problem
Both sides are the same so they are equal so...
4x+13=5x-15
x=28
Answer:
The 99% confidence interval for the true mean number of hours a union member is absent per month is (0 hours, 16.5125 hours).
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find M as such

In which s is the standard deviation of the sample.
So

The lower end of the interval is the mean subtracted by M. So it is 7.5 - 9.0125 = -...
There is not a negative number of hours. So the lower end of the interval is 0 hours.
The upper end of the interval is the mean added to M. So it is 7.5 + 9.0125 = 16.5125 hours.
The 99% confidence interval for the true mean number of hours a union member is absent per month is (0 hours, 16.5125 hours).
Answer:
1) b would be easier because it’s 1/2bh and since the base of 10 is easily divisible by 2 you don’t have to deal with fractions.
D=sqrt (x2-x1)^2+(y2-y1)^2
D=10
