The common ratio for the geometric sequence is :
<span>32</span>
Explanation:
<span>16,24,36,54</span>
We calculate the common ratio r:
r is obtained by dividing a term by its preceding term
1) <span><span>2416</span>=<span>32</span></span>
2) <span><span>3624</span>=<span>32</span></span>
The common ratio for the geometric sequence is :

The median for city A is 4 and the median for city B is 5.25.
To solve this problem, we make use of the z statistic.
What we have to do here is to find for the z score using the given data and
from the standard probability tables for z, we locate the proportion of the
fish longer than 12 inches.
The formula for calculating the z score is:
z = (x – μ) / σ
where,
x = the sample value = 12 inches
μ = the sample mean = 11 inches
σ = 2 inches
so,
z = (12 – 11) / 2
z = 1 / 2
z = 0.5
Since we are looking for the values greater than 12, so
this is a right tailed test. Using the tables, the value of p at this value of
z is:
p (z = 0.5) = 0.3085
Therefore there is a 30.85% probability that the fish is
longer than 12 inches.
I am not positive for the factoring of each expression but for the distributive property you do 8 TIMES x then 8 times 7 so you would get blank plus blank and so on for the next ones.
