Standard automobile license plates in a country display 1 numbers, followed by 3 letters, followed by 3 numbers. How many different standard plates are possible in this system? (Assume repetitions of letters and numbers are allowed.)
The counting principle says that we multiply the number of ways for each of these events together to get the total number of ways to get a license plate. Hence, there are \(158184000\) ways to create a license plate.
What is the counting principle?
The fundamental counting principle states that if there are \(p\) ways to do one thing and \(q\) ways to do another thing, then there are \(p\)×\(q\) ways to do both things.
So,
The number of ways to count the first number are \(9\) ways.
The number of ways to count the first letter are \(26\) ways
The number of ways to count the next letter are \(26\) ways
The number of ways to count the third letter are \(26\) ways
The number of ways to count the next number are \(10\) ways
The number of ways to count the next number are \(10\) ways
The number of ways to count the next number are \(10\) ways
So, the total number of ways to get a license plate is:-
\((9).(26).(26).(26).(10).(10).(10)=158184000\).
Hence, there are \(158184000\) ways to create a license plate.

Step-by-step explanation:
A fish descends 4 meters per minute for 2 minutes. Then it ascends 3 meters per minute for 3 minutes. What is the total distance, in meters, the fish traveled?
The fish's total distance traveled is 17 meters in 5 minutes based on multiplication and addition operations.
How is the total distance traveled determined?The total distance the fish traveled can be determined using mathematical operations, especially multiplication and addition.
We know that distance is the product of speed and time, i.e. d = st, where s is speed, t is time, and d is distance.
In this situation, we separately find the distance the fish traveled during its descent and ascent by multiplying time and speed.
The results are added to obtain the total distance the fish traveled for both activities.
The fish's descent speed = 4 meters per minute (MPM)
The total time for the descent = 2
The total distance for the descent = 8 miles (4 x 2)
The fish's ascent speed = 3 meters per minute (MPM)
The total time during ascent = 3 minutes
The total distance for the ascent = 9 miles (3 x 3)
The total distance the fish traveled for descent and ascent = 17 meters (8 + 9)
Thus, we can mathematically conclude that the fish traveled 17 meters.

Rectangles abcd and klmn are similar. If their permitted are 20 and 16, and the area of the larger rectangle is 25, what is the area of the smaller rectangle?
The area of the smaller rectangle (KLMN) is 16.
Since rectangles ABCD and KLMN are similar, their corresponding sides are proportional.
Let's assume the length of side AB in rectangle ABCD is x, and the length of side KL in rectangle KLMN is y.
We can set up the proportion:
(x/y) = (20/16)
To find the area of the smaller rectangle, we need to determine the ratio of their areas.
Since the area of a rectangle is given by the product of its length and width, the ratio of the areas will be equal to the square of the ratio of their sides:
(Area of ABCD)/(Area of KLMN) = (x²)/(y²)
We are given that the area of ABCD is 25, so we have:
25/(Area of KLMN) = (x²)/(y²)
To find the area of KLMN, we need to substitute the values of x and y from the proportion:
25/(Area of KLMN) = (20/16)²
Simplifying the right side:
25/(Area of KLMN) = (5/4)²
25/(Area of KLMN) = 25/16
Cross-multiplying:
25 × 16 = 25 × (Area of KLMN)
400 = 25 × (Area of KLMN)
Dividing both sides by 25:
16 = Area of KLMN
Therefore, the area of the smaller rectangle (KLMN) is 16.

A population is normally distributed with a mean of 56 and a standard deviation of 12.
What is the mean of the sampling distribution for this population?
The calculated value mean of the sampling distribution for this population is 56
Calculating the mean of the sampling distribution for this population?The mean of the sampling distribution for a population with a normal distribution is equal to the population mean.
Therefore, in this case, the mean of the sampling distribution is also 56.
To understand why this is the case, we can consider the central limit theorem, which states that the sampling distribution of the mean of a random sample from a population with any distribution will be approximately normal if the sample size is large enough.
This means that as the sample size increases, the mean of the sampling distribution approaches the population mean.
Therefore, the mean of the sampling distribution for this population is 56.

the total price of the dinner including tax is $37.26.the sales tax rate is 8%. how much did the dinner cost not including sales tax HELP PLSS
A 13.75
B 75.00
C 83.75
D 139.28
The required cost of the dinner not including sales tax was $34.28.
What is sale tax?A sales tax is a fee that is paid to the government when specified goods and services are sold. Typically, laws permit the vendor to charge the customer the tax at the time of purchase. Use taxes are typically used to describe taxes on goods and services that consumers pay directly to a governing authority.
According to question:
To find out how much the dinner cost before sales tax, we need to subtract the sales tax amount from the total cost.
We know that the sales tax rate is 8%. To find the sales tax amount, we can multiply the total cost by 8% (or 0.08):
Sales tax = 0.08 * $37.26 = $2.98
To find the cost of the dinner before sales tax, we can subtract the sales tax amount from the total cost:
Cost before sales tax = $37.26 - $2.98 = $34.28
Therefore, the cost of the dinner not including sales tax was $34.28.

After a 4% reduction, you purchase a new suit for $288. What was the original price of the suit?
Answer:
$300
Step-by-step explanation:
Let \(x\) be the original price.
\(x \times (1-0.04)=288\)
\(0.96x=288\)
\(x=\frac{288}{0.96}\)
\(x=300\)
Answer:
$300
Step-by-step explanation:
If it was a 4% reduction then we get:
\(x*0.96=288\\\)
Divide both sides by 0.96
\(x=300\)
The original suit price was $300

Find the approximate area of the shaded region. Use 3.14 for pi
The area of the shaded region of the rectangle is approximately 573.92 square feet.
What is the area of the shaded region?The figure in the image is that of a rectangle with a semi-circle inscribed in it.
The area of rectangle is expressed as:
Area = Length × Width
The area of semi-circle is expressed as:
Area = 1/2 × πr²
To determine the area of the shaded region, we simply subtract the area of the semi-circle from the area of the rectangle.
Area of shaded region = area of rectangle - area of semi-circle
Area of shaded region = ( Length × Width ) - ( 1/2 × πr² )
From the image:
Length = 40 ft
Width = 20 ft
Radius r = 12 ft
Plug the values into the above formula:
Area of shaded region = ( Length × Width ) - ( 1/2 × πr² )
Area of shaded region = ( 40 × 20 ) - ( 1/2 × 3.14 × 12² )
Area of shaded region = ( 800 ) - ( 226.08 )
Area of shaded region = 573.92 ft²
Therefore, the area is approximately 573.92 square feet.

hile watching a car move down the street, you close your eyes and count off 15 seconds. When you open your eyes again, the car is 144 feet further down the road from when you last saw it.WHAT IF the car traveled at a constant speed while your eyes were closed - how fast would it have had to travel?a. What constant speed would allow the car to travel exactly 144 feet in exactly 15 seconds?Select an answer second ft/sec feetb. If a car traveled at this speed for tt seconds, what formula would model its distance dd (in feet) from the starting point in terms of the time elapsed, tt (in seconds)? Recall that this does not necessarilly represent the actual relationship between the distance traveled and time elapsed for the real car. This represents the relationship for an imaginary car traveling at a constant speed.s = d/t
Answer:
below
Step-by-step explanation:
A. To find the constant speed that allows the car to travel exactly 144 feet in exactly 15 seconds, we can use the formula: speed = distance / time.
So, speed = 144 feet / 15 seconds = 9.6 feet/second.
B. If a car traveled at a constant speed of 9.6 feet/second for t seconds, the formula for its distance dd (in feet) from the starting point in terms of the time elapsed, tt (in seconds) would be:
dd = 9.6 feet/second * t seconds = 9.6t feet.

\(\log 0.3 &=\log \frac{3}{10} \\ \\ =\log 3-\log 10 \\=y-1\)
Answer (3)
\(\log 10.5& \\ =\log \frac{21}{2} \\=\log 21-\log 2\\ \\ \log 10.5& \\ =\log 3\times 7-\log 2\\=\log 3+\log 7-\log 2\\=y+z-x\)
