A computer password consists of six characters.a. How many different passwords are possible if each character may be any lowerca
Citrus2011 [14]

Answer:

a) 6.04661760*10^8

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

6.04661760*10^8

b)

By the <em>Fundamental Rule of Counting</em>, there would be  

36^6

different combinations of 6 characters, but only the number computed in a) are valid combinations, so the probability of generating a valid password is

\displaystyle\frac{10*36^5}{36^6}=\displaystyle\frac{10}{36}=0.27778

Simplify this expression.<br> 20.25 – 9 + 11<br> о<br> 1<br> 4<br> 0 18.75<br> 0<br> 21?<br> 0 40.75
Greeley [361]

Answer:

21\frac{3}{4}

Step-by-step explanation:

Step 1: Add the numbers.

20.25 can also be expressed as 20\frac{1}{4}, because \frac{2025}{100} = \frac{81}{4} = 20\frac{1}{4}. So if we add 20\frac{1}{4} and 11, we would get 31\frac{1}{4}

Step 2: Solve

31\frac{1}{4} -9\frac{1}{2}

  • Subtract the whole numbers

31-9=21

  • Combine the fractions

This means addition. Also, since our denominators are not the same value, we have to find the LCM (Least Common Denominator): What do 2 and 4 have in common that they can divide themselves by? 4. We know this because 2 divided by 4 is 2, and 4 divided by 4 is 1, so they can both divide themselves by 4.

\frac{5}{4}-\frac{1}{2}

LCM

\frac{5}{4}-\frac{2}{4} =\frac{3}{4}

Therefore, the simplified expression to this is 21\frac{3}{4}.
