Suppose that the format for license plates in a certain state is two letters followed by four numbers. (a) How many different pl
Ymorist [56]

Answer:

(a) 6,760,000 plates

(b) 3,407,040 plates

(c) 6,084,000 plates

Explanation:

The very first thing to note about this question is the number of characters involved in the license plate format (6 characters in this case; 2 letters and 4 numbers). The letters come first and then the numbers follow.

There are a total of 26 possible letters (A-Z) and 10 possible numbers (0 - 9) that can be chosen. We can then proceed to the first question;

(a) Here, the total number of possible plates is to be determined. This is done as follows:

Character 1 (Letter): There are 26 possible letters

Character 2 (Letter): There are 26 possible letters

Character 3 (number): There are 10 possible numbers

Character 4 (number): There are 10 possible numbers

Character 5 (number): There are 10 possible numbers

Character 6 (number): There are 10 possible numbers

So, total number of different plates will be obtained by multiplying all the possibilities: 26 × 26 × 10 × 10 × 10 × 10 = 6,760,000 plates

(b) This second part puts a constraint on the usage of the numbers, unlike the question (a), where there was no constraint at all.

Since there is no constraint on the letters, we can write that:

Character 1 (Letter): There are 26 possible letters

Character 2 (Letter): There are 26 possible letters

For the first number as well, we can write:

Character 3 (number): There are 10 possible numbers

However, for the remaining characters, the possibilities will continually reduce by a value of 1, since we can not use a number that has been used before. So,

Character 4 (number): There are 9 possible numbers

Character 5 (number): There are 8 possible numbers

Character 6 (number): There are 7 possible numbers

So, total number of different plates will be: 26 × 26 × 10 × 9 × 8 × 7 = 3,407,040 plates

(c) Here, repetitions are allowed as in questions (a), but there can not be four zeros. This implies that the maximum number of zeros in any plate will be three. Thus, there will be maximum possibilities on all characters until the last one which will be constrained.

Character 1 (Letter): There are 26 possible letters

Character 2 (Letter): There are 26 possible letters

Character 3 (number): There are 10 possible numbers

Character 4 (number): There are 10 possible numbers

Character 5 (number): There are 10 possible numbers

Character 6 (number): There are 9 possible numbers

Total number of plates will therefore be: 26 × 26 × 10 × 10 × 10 × 9 = 6,084,000 plates.

4.22 lab*: program: automobile service invoice(1) output a menu of automotive services and the corresponding cost of each servic
azamat

To write the code for this exercise, we must be familiar with Python's computational language.

The attachment contains the code.

As a result, the Python code can be written as follows:

0 service1 cost

0 service2 cost

print("Services at Davey's Auto Shop")

print("Oil change: $35; Tire rotation: $19; Car wash: $7; Car wax: $12;"

input = service1 ("Select first service: ")

product2 = input ("Select second service: ")

If "Oil change" is service 1, then

35 service1 cost

Tire rotation: elif service1 == true

cost1 service1 = 19

"Car wash," if service1 is true:

cost service1 = 7

"Car wax" if service1 is true:

cost service1 = 12

if (service1) == "-":

service 1 equals "No service"

0 service1 cost

When service2 equals "Oil change,"

35 service2 cost

Tire rotation: elif service2 == true

cost2 service2 = 19

"Car wash" if service2 is true:

cost2 service2 = 7

"Car wax" if service2 is true:

cost2 service2 = 12

Which is needed for the specific task of inserting a chart into a report?
Arturiano [62]

To add charts in Access to reports, click the “Create” tab in the Ribbon. Then click the “Report Design” button in the “Reports” button group. Unlike other report controls, the chart control uses its own data source to show its data. Therefore, you can insert it into a blank, unassociated report, if desired
