3x+2(3x-3)=2
9x-6=2
9x=8
X=8/9
Solution:
formula : an=a1(r)^n-1
n - number of term that is unknown
a1 - first term
r - second term divided by the first term
a1=-6
a2=24
a3=?
a4=384
a5=-1536
a3=-6(24÷-6)^3-1
a3=-6(-4)^2
a3=-96
therefore the 3rd term is -96 (c)

Answer:
We have to find the 90% confidence interval for the mean
Given sample size
Sample mean
Population standard deviation
Here the confidence level is 90% then
And
The 90% confidence interval is
Here is the critical value at 0.05
From the tables
Now the 90% confidence interval is =
=
=(3840.44, 4133.56)
Hence the 90% confidence interval for the mean is (3840.44, 4133.56)
