Mary must choose a new password where the first and last choices are possibly repeated lowercase letters; the second and third
Salsk061 [2.6K]

The number of ways she can choose a password is 3986236800

<h3>In how many ways can she choose a password?</h3>

The given parameters and the possible selection of characters are:

First and last choices are possibly repeated lowercase letters;

There are 26 lower characters.

Since the characters can be repeated, then we have

First = 26

Last = 26

The second and third positions must be distinct uppercase letters

There are 26 upper characters.

Since the characters are distinct, then we have

Second = 26

Third = 25

The fourth position must be a # , $, or & symbol;

So, we have

Fourth = 3

The next four positions are distinct nonzero digits.

There are 9 nonzero digits.

Since the digits are distinct, then we have

Next = 9, 8, 7, 6

The number of ways she can choose a password is

Ways = First * Second * Third * Fourth * Next * Last

So, we have

Ways = 26 * 26 * 25 * 3 * 9 * 8 * 7 * 6 * 26

Evaluate the product

Ways = 3986236800

Hence, the number of ways she can choose a password is 3986236800

The distance around the pool is 43.96 m.

Solution:

The distance across the circle is <em>diameter</em>.

The distance around the circle is <em>circumference</em>.

The value of π = 3.14

Diameter of the circle = 14 m

Circumference of the circle = πd

                                              = 3.14 × 14 m

Circumference of the circle = 43.96 m

The distance around the pool is 43.96 m.

It takes 12 painters to paint the walls of a school in 21 days. In how many days the same job will be completed with 14 painters
nikklg [1K]

Answer:

18 days.

Step-by-step explanation:

We have been given that 12 painters paint the wall of a school in 21 days.

So the wall painted by one painter will paint the wall in 21\times 12\text{ days}=252\text{ days}

As one painter will paint the wall in 252 days, so to find the number of days it will take to paint the same wall by 14 painters, we will divide time taken by one painter (252) by 14.

\text{Time take by 14 painters to paint the wall}=\frac{252}{14}

\text{Time take by 14 painters to paint the wall}=18

Therefore, it will take 18 days to paint the same wall by 14 painters.
