A proportional relationship is used to illustrate linear equations.
The constant of proportionality is 3
From the table, we have the following points:
(x,y) = (2,6) (3,9)
The constant of proportionality is calculated using:
So, we have:
Subtract
Divide
Hence, the constant of proportionality is 3

Answer:
a)
b) 0.27778
Step-by-step explanation:
a)
There are 26 lowercase letters and 10 digits.
The character that must be a digit can be generated in 10 different ways and the others, in 26+10=36 different ways.
Since the password is 6 characters long, by the Fundamental Rule of Counting there are
10*36*36*36*36*36 = 604,661,760
In scientific notation this number can be expressed as
b)
By the <em>Fundamental Rule of Counting</em>, there would be
different combinations of 6 characters, but only the number computed in a) are valid combinations, so the probability of generating a valid password is
