If the part is 18 and the whole is 25 whats the percent?

1 answer:

6 0

First you would have to convert the number to a decimal. To convert a fraction to a decimal, divide the denominator by the numerator. So 18/25=0.72

Next to convert a decimal to a percent, move the decimal point over two places then add a percent sign.

so .72 becomes 72%

18/25 as a percent is 72%

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:

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

$6.04661760*10^8$

By the Fundamental Rule of Counting, 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

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