find the range of the following data set 31,31,22,28,23
Answer:
9
Step-by-step explanation:
since 2 is the minimum and 31 is the maximum you subtract 31 by 22
To find the range of the given data set, follow these steps:
1. Identify the maximum value in the data set.
2. Identify the minimum value in the data set.
3. Subtract the minimum value from the maximum value.
Let's apply these steps to the provided data set:
Data set: 31, 31, 22, 28, 23
Step 1: Find the maximum value.
Looking at the numbers, the maximum value is 31. (Both occurrences of 31 are considered, but since they are the same, the maximum is still 31.)
Step 2: Find the minimum value.
Looking at the numbers, the minimum value is 22.
Step 3: Calculate the range.
Subtract the minimum value from the maximum value: 31 - 22 = 9.
Hence, the range of the given data set is 9.
Find the circumference if radius =26
Circumference can be found using [tex]C=2\pi r[/tex] formula. Where [tex]r[/tex] is radius.
Now we just put in the data.
[tex]C=2\pi\times26=52\pi\approx\boxed{163.36}[/tex]
If the radius is 26, firstly we have to calculate the diameter. The diameter is 2 times the radius.
Radius = 26
Diameter = 26 × 2 = 52
Circumference of circle = π × Diameter
= π × 52
= 163.3628 or 163.4 (to 1 dp)
A total of 800 pre-sale tickets and tickets at the gate were sold to the football city championship game. if the number of tickets sold at the gate was thirteen less then twice the number of pre-sale tickets, how many pre-sale tickets were sold?
ANSWER
271 pre-sale tickets were sold.
EXPLANATION
Let p represent the number of pre-sale tickets and t represent the number of tickets sold.
According to the question,a total of 800 pre-sale tickets and tickets were sold .
This implies that,
[tex]p + t = 800[/tex]
Also the number of tickets sold is 13 less than twice the number of pre-sale tickets.
This gives another equation:
[tex]t = 2p - 13[/tex]
We substitute, the second equation into the first equation to obtain:
[tex]p + 2p - 13 = 800[/tex]
This implies that;
[tex]3p = 813[/tex]
Divide both sides by 3
[tex]p = \frac{813}{3} = 271[/tex]
Hence 271 pre-sale tickets were sold.
By setting up an algebraic equation and denoting pre-sale tickets as x, we discover that 271 pre-sale tickets were sold for the football city championship game.
To solve the problem of how many pre-sale tickets were sold for the football city championship game, we can set up an algebraic equation. Let's denote the number of pre-sale tickets as x. According to the question, the number of tickets sold at the gate is thirteen less than twice the number of pre-sale tickets, which we can express as 2x - 13. We are given that the total number of tickets sold is 800.
So, we set up the equation:
x + (2x - 13) = 800
Combining like terms, we get:
3x - 13 = 800
Adding 13 to both sides:
3x = 813
Then we divide both sides by 3 to find the value of x:
x = 813 / 3
x = 271
Therefore, 271 pre-sale tickets were sold.
Algebra manipulation. Thank you! My answer is - 8/5 but I want to make sure :)
Start with
[tex]\dfrac{2a+3b}{a+b}=7[/tex]
Assuming [tex]a\neq -b[/tex], multiply both sides by [tex]a+b[/tex]
[tex]2a+3b = 7a+7b[/tex]
Solve for [tex]a[/tex]
[tex]5a = -4b \iff a = -\dfrac{4b}{5}[/tex]
Substitute this value for [tex]a[/tex] in the desired expression:
[tex]\dfrac{2a}{b} = \dfrac{\frac{-8b}{5}}{b} = -\dfrac{8}{5}[/tex]
You were correct! :)

write the nth term of sequence in terms of the first term of the sequence
Final answer:
The nth term of the sequence can be found using the formula Tn = a + 4(n - 1), where a is the first term and n is the term position. This is based on the characteristics of an arithmetic sequence.
Explanation:
This pattern indicates that the sequence is an arithmetic sequence, where each term is obtained by adding a constant difference to the preceding term.
To find the nth term of an arithmetic sequence, we use the formula:
Tn = a + (n - 1)d
Where Tn is the nth term, a is the first term, n is the position of the term in the sequence, and d is the common difference between terms. For this sequence, d = 4.
Substituting the known values into the formula gives us:
Tn = a + 4(n - 1)
This expression allows us to calculate the nth term of the sequence given the first term (a) and the position (n) of the term we want to find.

Answer:
Part a) The width of parking lot is 87m.
Part b) The length of rectangular pool is 94 m
Step-by-step explanation:
a) The area of parking lot Area= 8439 m^2
Length of Parking Lot = Length = 97 m
Width of Parking Lot = Width= ?
Area of rectangle = Length * Width
Putting the values,and finding width,
8439 = 97 * Width
=> Width = 8439/97
=> Width = 87 m
So, The width of parking lot is 87m.
b) Perimeter of rectangular pool = Perimeter= 344 m
Width of rectangular pool = Width = 78 m
Length of rectangular pool = Length = ?
The formula for perimeter is:
Perimeter = 2*(Length + Width)
Putting values in the formula:
344 = 2*(Length + 78)
344/2 = Length + 78
172 = Length + 78
=> Length = 172 - 78
Length = 94 m
So, the length of rectangular pool is 94 m.

What is the product of 2x + y and 5x – y + 3?
Answer:
The correct answer is 10x² + 3xy + 6x - y² + 3y
Step-by-step explanation:
It is given an expression (2x + y)(5x - y + 3)
To find the product
(2x + y)(5x - y + 3) = 2x * 5x - 2x*y + 2x*3 + y*5x -y² + 3y
= 10x² - 2xy + 6x + 5xy - y² + 3y
= 10x² + 3xy + 6x - y² + 3y
Therefore the correct answer is
10x² + 3xy + 6x - y² + 3y
The product of (2x + y) and (5x – y + 3) is found by using the distributive property of multiplication over addition, which gives us: 10x^2 + 3xy + 6x - y^2 + 3y.
Explanation:To find the product of (2x + y) and (5x – y + 3), we need to use the distributive property of multiplication over addition. This involves multiplying each term within the first parentheses by each term in the second parentheses.
The steps are as follows:
Multiply 2x by each term in the second parentheses: (2x*5x, 2x*-y, 2x*3)Multiply y by each term in the second parentheses: (y*5x, y*-y, y*3)Sum up all the products obtained.The result is 10x^2 -2xy + 6x + 5xy - y^2 + 3y. Simplifying further gives us: 10x^2 + 3xy + 6x - y^2 + 3y.
So, the product of (2x + y) and (5x – y + 3) is 10x^2 + 3xy + 6x - y^2 + 3y.

determine if -1, 1, 4, 8 is a geometric sequence
ANSWER
No, because there is no common ratio
EXPLANATION
The given sequence is
-1, 1, 4, 8
If this sequence is geometric, then there should be a common ratio among the consecutive terms.
[tex] \frac{1}{ - 1} \ne \frac{4}{1} \ne \frac{8}{4} [/tex]
Hence the sequence
-1, 1, 4, 8
is not a geometric sequence.
Answer:
The sequence is not a geometric sequence
Step-by-step explanation:
In a geometric sequence you find the following term multiplying the current by a fixed quantity called the common ratio.
To prove if a sequence is geometric we need to check if the ratio is consistent across the sequence. To check for the ratio we use the formula:
[tex]r=\frac{a_n}{a_{n-1}}[/tex]
were
[tex]r[/tex] is the ratio
[tex]a_n[/tex] is the current term
[tex]a_{n-1}[/tex] is the previous term
Let's star with 1, so [tex]a_n=1[/tex] and [tex]a_{n-1}=-1[/tex]
[tex]r=\frac{a_n}{a_{n-1}}[/tex]
[tex]r=\frac{1}{-1}[/tex]
[tex]r=-1[/tex].
Now let's check 4 and 1, so [tex]a_n=4[/tex] and [tex]a_{n-1}=1[/tex]
[tex]r=\frac{a_n}{a_{n-1}}[/tex]
[tex]r=\frac{4}{1}[/tex]
[tex]r=4[/tex]
Since the ratios between two pair of numbers are different, we can conclude that the sequence is not geometric.
