License plates on cars are composed of up to 7 characters. The characters can either be a digit (0,1,...,9) or an uppercase lett

er (A,B,...,Z). For example, your license plate could be: AA04R32 or S9332. (Explain your answers for each part.) (a) (3 points) How many possible license plates are there that have at least one even number and at least one vowel? (b) (3 points) Since O’s and 0’s look similar, in some states, a valid license plate cannot have both an O and a 0. How many such 7-character license plates are there? (c) (3 points) How many possible 7-character license plates are there such that the first 3 characters are 3 distinct digits in increasing order and the remaining 4 characters are 4 distinct letters in alphabetical order? (d) (3 points) There is a particular 4-letter word that is not allowed on any license plate. (Let’s pretend that the word is MATH.) How many 7-character license plates avoid the word MATH?

El productor del números es 28. Sabiendo que el primer número es 3 unidades menor que el segundo, calcula los dos número
Rasek [7]

Answer:

Tienes 3 números, "x", "y", "z"

=> El primero es 20 unidades menor que el segundo:

El primero es "x", y el segundo es "y", entonces:

x = y - 20

=> El tercero es igual a la suma de los dos primeros:

El tercero es "z", entonces:

z = x + y

z = (y - 20) + y

z =  2y - 20

=> Entre los tres suman 120

x + y + z = 120

y - 20 + y + 2y - 20 = 120

4y - 40 = 120

4y = 160

y = 40

Si y = 40, entonces:

x = y - 20

x = 20

Además, z = 2y - 20

z= 60

RPTA:

x=20

y=40

z=60

In a retail setting, payroll is often based on projected sales. If your payroll budget is 6% of projected sales of $3500.00 and
Bad White [126]

The maximum number of hours that can be allocated in a day is 21

Data given;

  • Sale = $3500
  • Employee pay = $10.00 per hour
  • Percentage allocated to employee = 6% of sales

<h3>Percentage</h3>

This is the process of finding a fraction of a value multiplied by 100.

Let's find the actual figure allocated to employee pay.

6% of $3500 is;

6/100 = x/ 3500\\x = 0.06*3500\\x = 210

The percentage out of sale allocated for employee pay is $210

Now we know the actual amount allocated to employee pay and it is $210.

Divide the amount allocated to employee pay by $10:00 to find the actual hours we can allocate in a day.

y = 210/10 = 21

The maximum number of hours we can allocate in a day is 21 hours.
