The two odd numbers are 11 and 15. The sum of the odd numbers in the sequence will be 26.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
It is given that,
The sequence is,
2,3,5,6,7,9,10,11,13…
As we know the given series is an arithmetic progression with a common difference is 2.
The sequence is further obtained as,
2,3,5,6,7,9,10,11,13, 15
From the given condition the sum of the numerals has to be 26.After applying a lot of addition to the sequence we get only two odd numbers 11 and 15 which will give the sum of 26 as,
= 11 + 15
=26

Two students were competing to have the
highest amount of sales at a bake sale.
Together they made $132. If each
student had made $15 more in sales, one
student would have made twice as much
as the other student.
How much money did the winning
student make, in dollars?
Amount of money made by thee winning student as per the given conditions is equal to $93.
As given in the question,
Let x dollars be the money made by winning student
And y be the amount made by other student
As per given conditions:
x + y = $132 ___(1)
x + 15 = 2(y+15)
⇒ x +15 = 2y +30
⇒ x-2y =15 ____(2)
Multiply (1) by 2 and add it to (2)
2x +2y = 264
x - 2y = 15
3x = 279
⇒x =$93

1/4 of a 24-hour period to read 1/3 of his book. At this rate, how many hoursto complete the book?
We have:
That in 1/4th of 24 hours someone reads 1/3rd of a book, in other words:
[tex]h=\frac{24}{4}\Rightarrow h=6[/tex]So in 6 hours someone reads 1/3rd of a book, now:
If in 6 hours someone reads 1/3 of a book, then how many hours will it take to read the whole book.
In order to solve for the ammount of hours to read the whole book, we multiply the ammount of hours it takes to read 1/3rd of the book (6h) times the total of the book (1 book) and divide by the ammount of book that is read in 6 hours (1/3rd); that is:
[tex]T=\frac{6\cdot1}{(\frac{1}{3})}\Rightarrow T=18[/tex]Therefore the total ammount of time it will take to read the whole book are 18 hours.

Convert the following phrase into a mathematical expression. Use x as the variable. Combine like terms when possible.A number multiplied by - 9, subtracted from the sum of 15 and two times the numberThe expression is(Simplify your answer.)
Given:
A number multiplied by - 9, subtracted from the sum of 15 and two times the number.
Let the number = x
A number multiplied by - 9 ⇒ -9x
The sum of 15 and 2 times the number ⇒ 15 + 2x
So, the expression will be ⇒ 15 + 2x - (-9x) = 11x + 15
So, the answer will be ⇒ 11x + 15

We need to solve the inequality:

By expanding the expression, we obtain:

What are mathematics operations?
• A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
From the question above, we can see that the laptop costs $350 more than the desktop, therefore, we say:
let x represent the cost of the laptop ;
then x-350 will be the cost of the desktop .
We can also see that the total finance charge of $400 is equal to 8% of the cost of the laptop and 7.5% of the cost of the desktop, we solve as follows:
400 = 0.08(x) + 0.075(x - 350)
252 = 0.08x + 0.075x - 26.25
252 26.75 = 0.155x
278.75 = 0.155x
x = 278.75/0.155
x = 1798
Recall that:
cost of desktop = x -350
therefore:
1,798- 350 = 1448
cost of laptop = $1798
cost of desktop = $1448
Thus, the cost of laptop and cost of desktop is $1,800 and $2,100 respectively does each computer cost before finance charges.

Explain what the MAD means in the context of the data
1)First, lets arrange our data in ascending order:

[tex]\begin{gathered} \min =1 \\ \max =35 \end{gathered}[/tex]now, since we have ten elements in your data set, we can find the median by adding the two central elements. In this case we have:
[tex]\begin{gathered} \operatorname{median}=\frac{8+12}{2}=\frac{20}{2}=10 \\ \operatorname{median}=10 \end{gathered}[/tex]Next, notice that we can divide our data set in two equal parts:

3)We can find the mean with the following formula:
[tex]\operatorname{mean}=\frac{\sum ^n_{i=1}x_i}{n}[/tex]In this case, the mean is:
[tex]\begin{gathered} \operatorname{mean}=\frac{1+5+8+8+8+12+12+14+16+35}{10}=\frac{119}{10}=11.9 \\ \operatorname{mean}=11.9 \end{gathered}[/tex]therefore, the average life span is 11.9
$)We can find the mean absolute deviation (or MAD), with the following expression:
[tex]\text{MAD}=\frac{\sum ^{}_{}|x_i-\operatorname{mean}|}{n}[/tex]with this expression we can find out the variability of the dataset.
In this case, we have the following:
[tex]\begin{gathered} \text{MAD}=\frac{|1-11.9|+|5-11.9|+|8-11.9|+|8-11.9|+|8-11.9|+|12-11.9|+|12-11.9|+|14-11.9|+|16-11.9|+|35-11.9}{10} \\ =\frac{10.9+6.9+3.9+3.9+3.9+0.1+0.1+2.1+4.1+23.1}{10} \\ =\frac{59}{10}=5.9 \\ \text{MAD}=5.9 \end{gathered}[/tex]We have that the MAD for the average lifespan is 5.9
5) Since the mean absolute deviation is 5.9, we can estimate that the values of the dataset are approximately 5.9 units away from the mean. therefore, there is a high variability in the life span of the animals

The function f(x) is a cubic function and the zeros of f(x) are −2, 1 and 2. The y-
intercept of f(x) is -8. Write the equation of the cubic polynomial in standard
form.
In linear equation, p(x) = -2x³ - 6x² - 12x - 8 is the equation of the cubic polynomial in standard form.
What is linear equation in math?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.Given the roots x1, x2, and x3 of a cubic polynomial, the equation can be written
p(x) = a( x - x₁ ) ( x - x₂) ( x - x₃ )
Where a is the leading coefficient.
We know the three roots of the polynomial −2, 1 and 2.
p( x ) = a( x + 2) ( x + 1 ) ( x + 2 )
Since the y-intercept of the polynomial is y= - 8 when x=0
- 8 = a( 0 + 2 ) ( 0 + 1 ) ( 0 + 2 )
- 8 = a * 4
- 8 = 4a
a = -8/4
a = -2
The polynomial is
p( x ) = -2( x + 2) ( x + 1 ) ( x + 2 )
We must write it in standard form, so we have to multiply all of the factors as follows
p(x) = -2 ( x + 1 )² ( x + 1 )
p(x) = -2 ( x² + 4 + 2x ) ( x+ 1 )
p(x) = -2 ( x₃ + 3x² + 6x + 4 )
p(x) = -2x³ - 6x² - 12x - 8
