As per the concept of probability,
a) There are 1757600 number of possible license plates can there be in this state if repetition of letters and numbers is permitted
b) There are 1404000 number of possible license plates can there be in this state if repetition of letters and numbers is not permitted.
Probability:
Probability refer the possible way of occurring the particular event.
Given,
License plates in a particular state are to consist of 2 digits followed by 3 uppercase letters.
Here we need to determine the number of possible license plates for both repetition phase and non repetition phase.
Here we know that, license plates consist of 3 letters followed by 2 digits.
Let us consider the numbers on license plates be N
Let us consider the letters on license plates be L
Then the license plate consisting of 3 letters and 2 digits will be writen as,
=> LLLNN.
We know that the letters can be anything from A to Z.
There are 26 letter combinations for the first letter.
Again second and third letters can be anything from the 26 letters.
So, combination for letters = 26 × 26 × 26 = 17576
Similarly, the numbers can be anything from 0 to 9.
There are 10 combinations for both places.
Then the combination for numbers = 10 × 10 = 100
Therefore, the total number of combination for letters and numbers
=> 17576 × 100 = 1757600.
Therefore, there are 1757600 license plates can be made with repetition.
Similarly, for non repetition mode,
The number of letters for each place is reduced before,
So, the combination for the letter is,
=> 26 x 25 x 24 = 15600
Similarly, the combination of numbers is,
=> 10 x 9 = 90
Therefore, the total number of combination is,
=> 15600 x 90 = 1404000

find the difference between the mode and median of the distribution of data
Step 1: Rewrite the dot plot in tabular form
Step : Compute the mode
From the table, we can see that the numer appears most ( that is the number with the highest frequence, f) is 4.
Therefore,
mode = 4
Step 3: Find the median
First arrange the data in ascending order. In this case, the data is already in ascending order.
If ∑f is odd, the median is the middle value which is at position
[tex]\frac{\sum f+1}{2}[/tex]If ∑f is even, the median is the average of the two values at positions
[tex]\frac{\sum f}{2}\text{ and }\frac{\sum f}{2}+1[/tex]In this case, ∑f = 12 is even.
Therefore, the median is the average of the numbers at position 6 and 7
number at position 6 is 3
number at position 7 is 4

A bird flying over water drops a crab from a height of 10 feet. The distance
the crab is from the water as it falls can be represented by d in the equation
d equals negative t to the power of 2 end exponent plus 10, where t is time in seconds. To catch the crab as it falls, a different
bird flies along a path represented by the equation d equals 5 t plus 5. In how many
seconds will the second bird catch the crab before it hits the water?
Solving a quadratic equation we can see that the second bird catches the crab after 0.85 seconds.
In how many seconds the second bird catches the crab?
The equation that describes the height of the crab is:
d = -t^2 + 10
The equation that represents the path of the second bird is:
d' = 5t + 5
The bird will be able to catch the crab when both are at the same height, this happens when:
-t^2 + 10 = 5t + 5
We need to solve this for t.
-t^2 + 10 - 5t - 5 = 0
-t^2 - 5t + 5 = 0
Using the quadratic formula we will get:
t = (5 ± √( (-5)^2 - 4*(-1)*5))/(2*-1)
t = (5 ± 6.7)/(-2)
We only care for the positive solution, which is:
t = (5 - 6.7)/(-2) = 0.85
So the bird catches the crab after 0.85 seconds.

In a bake sale, you recorded the number of muffins sold and the amount of sales in a table as shown. a. What is a function that relates the sales and the number of muffins?b. How many muffins would you have to sell to make at least $175.000 in sales?a. Write the function.s= ______. (Type and expression using m as the variable.)
The function is S = N*1.75. The number of muffins that must be sold to earn $175 is 100.
The number of muffins sold and the amount of sales in a bake sale are shown in the given table. The number of muffins sold is 12, 14, 17, and 18. The amount of the sale is $21, $24.5, $29.75, and $31.5. We can write these in the form of coordinates as (12, 21), (14, 24.5), (17, 29.75), and (18, 31.5).
We should first determine if the ratio is constant. The ratio is the division of the sales amount by the respective number of muffins sold. We find that the ratio of all the pairs is the same and is equal to 1.75. We can form an equation as given below :
S = N*1.75
The variables "S" and "N" represent the sales amount and the number of muffins, respectively. We need to find the number of muffins that need to be sold to earn $175.
S = N*1.75
175 = N*1.75
N = 100

Your company fireworks show is getting bigger, The boss has requested that the viewing area (which is 4 ft x 6 ft) be doubled; the parking area (which is 540 ft x 75 ft) be doubled; and the city ordinance requires the fireworks to be in the air less than 4 seconds and not go any higher than 600 feet.
Answer the following questions:
1. Determine the dimensions of the new viewing area. The existing area is 6 ft long by 4 ft wide.
2. Determine the dimensions of the new parking area. The existing area is 540 ft long by 75 feet wide.
3. Determine the height of the fireworks and how long they are in the air using the following equation:
ℎ= −500/9 t^2 + 1000/3 t + 10
The solution to the questions are
New viewing area dimension: 8 ft by 12 ftNew parking area dimension: 1080 ft by 150 ftHeight of fireworks: 510 unitsThe dimension of the new viewing areaFrom the question, we have the following parameters:
Initial dimension of the viewing area:
4 ft by 6 ft
The scale of dilation is given as
Scale = 2 (i.e. doubled)
Using the above as a guide, the new dimensions are calculated using
New = Old * Scale
So, we have
New = (4 ft by 6 ft) x 2
Evaluate
New = 8 ft by 12 ft
The dimension of the new parking areaThe given parameters are
Initial dimension of the parking area:
540 ft by 75 ft
We use the same scale factor as (a) i.e.
Scale = 2 (i.e. doubled)
Using the above as a guide, the new dimensions are calculated using
New = Old * Scale
So, we have
New = (540 ft by 75 ft) x 2
Evaluate
New = 1080 ft by 150 ft
The height of fireworksThe function is given as
ℎ= −500/9 t^2 + 1000/3 t + 10
Differentiate the function
So, we have
ℎ'= −1000/9 t + 1000/3
Set the differentiated function to 0
So, we have
−1000/9 t + 1000/3 = 0
This gives
1000/9 t = 1000/3
Multiply both sides by 9/1000
t = 3
Substitute 3 for t in ℎ= −500/9 t^2 + 1000/3 t + 10
ℎ = −500/9 x 3^2 + 1000/3 x 3 + 10
Evaluate
ℎ = 510
Hence, the height is 510 units
