Your answer would be 17.5 I just took the test I got it right
Given that the geometric series is given by:
f(n)=an=1.2f(n-1) where a1=6, then f(38) will be found as follows:
a2=1.2f(2-1)=1.2f(1)=1.2*6=7.2
a3=1.2f(3-1)=1.2f(2)=8.64
thus the common ratio is r=1.2
but
explicit formula for geometric sequence is:
an=ar^(n-1)
thus plugging our values:
f(38)=6(1.2)^(38-1)
f(38)=5103.3735

The mean is calculated by adding all the values and then dividing by how many numbers there were
We know the mean is 10 and there were 5 values
10 x 5 = 50
We now know the numbers must add up to 50 and have a range of 10 (the difference between the largest and smallest number
Examples of 5 numbers
6, 7, 10, 11, 16
5, 7, 10, 13, 15
4, 7, 11, 14, 14
Answer: There are 1000 different passwords.
Step-by-step explanation:
Given: A password contains three digits.
Number of digits from 0 to 9 = 10
Using fundamental principle of counting,
The number of different passwords = (Number of choices for digits) x (Number of choices for digits) x (Number of choices for digits)
= (10) x (10)x (10)
=1000
Hence, there are 1000 different passwords.
