Answer:
The two consecutive integers are -119 and -120
Step-by-step explanation:
As we know that these two integers are consecutive, that means that they will have a difference of 1. This means that we can find the two integers by adding 1 to the sum of -239 and then dividing it by two
[tex]1-239=-238\\\frac{-238}{2} =-119\\-119-1=-120[/tex]
When needing to determine two consecutive integers with a given sum, they can be represented as 'x' and 'x+1'. The equation x + (x + 1) = -239 gives us the solution of the two integers as -120 and -119.
Explanation:In the given question, since we are dealing with consecutive integers, we can represent the integers as 'x' and 'x+1'. As per the information in the question, we know that the sum of these two consecutive integers is -239. Therefore, we can create the equation:
x + (x + 1) = -239
Solving this equation gives us:
2x + 1 = -239
Therefore,
2x = -240
So, x = -120
This indicates that our first integer is -120. Because we are dealing with consecutive integers, the next integer would be -120 + 1 = -119. Thus, the two consecutive integers are -120 and -119.

Answer:
A. [tex]C=K-273[/tex]
Step-by-step explanation:
You are given the formula
[tex]K=C+273[/tex]
You have to find C in terms of K. Subtract 273 from both sides of this equation:
[tex]K-273=C+273-273\\ \\K-273=C\\ \\C=K-273[/tex]
ANSWER
C=K-273
EXPLANATION
The given formula is: K=C+273
We need to solve this formula for the variable, C.
This means that we need to isolate the variable C on one side of the equation, leaving any other terms on the other side of the equation.
We subtract 273 from both sides of the equation to obtain,
K-273=C
This is the same as
C=C-273
Ari’s teacher says he may have his report grade based on either the mean or the median of his last six test scores.
88%, 73%, 97%, 76%, 90%, 80%
Which measure of center would best represent Ari’s grade?
The mean would be the best! The mean is when you add up all of those grades and divide by the amount of exams.
If you're solving it,

THIS IS 61 POINTS. Find the first three terms of the sequence described by the following recursive formula: an = 3an – 1 + 2 where a4 = 20
a1=
a2=
a3=
Answer:
see explanation
Step-by-step explanation:
Given the recursive formula
[tex]a_{n}[/tex] = 3[tex]a_{n-1}[/tex] + 2 and a₄ = 20
Then working in reverse
3a₃ + 2 = 20 ( subtract 2 from both sides )
3a₃ = 18 ( divide both sides by 3 )
a₃ = 6
3a₂ + 2 = 6 ( subtract 2 from both sides )
3a₂ = 4 ( divide both sides by 3 )
a₂ = [tex]\frac{4}{3}[/tex]
3a₁ + 2 = [tex]\frac{4}{3}[/tex] ( subtract 2 from both sides )
3a₁ = - [tex]\frac{2}{3}[/tex] ( divide both sides by 3 )
a₁ = - [tex]\frac{2}{9}[/tex]
Hence
a₁ = - [tex]\frac{2}{9}[/tex]
a₂ = [tex]\frac{4}{3}[/tex]
a₃ = 6
a1 = (-2/9)
a2 = 4/3
a3 = 6

Answer:
The ratio of flour to sugar is 2:1
Step-by-step explanation:
Let f = weight of a bag of flour
Let s = weight of a bag of sugar
3f+2s = 32
4f = 32
We have 2 equations and 2 unknowns, we can solve
4f=32
Divide by 4
4f/4 = 32/4
f = 8
Each bag of flour weights 8 pounds
Substitute this back into the first equation
3(8) +2s = 32
24+2s = 32
Subtract 24 from each side
24-24 +2s =32-24
2s = 8
Divide by 2
2s/2 = 8/2
s = 4 pounds
Flours weighs 8 pounds and sugar weights 4 pounds
We want the ratio of flour to sugar
Flour: sugar
8:4
We can divide each side by 4
8/4: 4/4
2:1

Answer:
a) third; from left most graph
b) fourth; right most graph
Step-by-step explanation:
Part a)
The graph is between the speed and time.
Nicole begin jogging faster and faster i.e. speed is increasing w.r.t time thus we have linear line in beginning.
Then she hits a comfortable speed and stayed at it i.e. speed remained constant for that time. Thus we have a straight line.
After that she gradually slows down,i.e speed is decreasing w.r.t time. Thus we have decreasing linear line.
So the graph shape is linear line with increasing slope-a constant straight line-linear line with decreasing slope
which is the third; from left most graph in option
Part b)
The graph is between Distance to campus and time.
As Dale is hiking towards campus, distance should decrease w.r.t time.
In beginning, he is hiking at constant speed towards campus thus the distance towards the campus is decreasing w.r.t time. We get a decreasing linear line.
*Note: here constant speed is not important, instead hiking towards i.e. the direction is important because of the campus distance covered
Then he sees a snake and turn and runs the other way. Thus now the distance towards the campus is increasing. And we get increasing linear line.
*Note running other way is important because of the campus distance covered
After that, he sits for a while i.e he stops and so the distance towards campus also become constant w.r.t time. we get a straight line on the graph.
So the graph shape is linear line with decreasing slope-linear line with increasing slope-a constant straight line
which is the right-most graph in option !

Step-by-step explanation:
The number 15. 24 is an example of a repeating decimal.
true. false.
No, the number 15.24 is not a repeating decimal.
Explanation:No, the number 15.24 is not an example of a repeating decimal.
A repeating decimal is a number whose decimal representation goes on forever and repeats a block of one or more digits. For example, the number 0.3333... is a repeating decimal because the digit 3 repeats infinitely.
In the case of 15.24, the decimal representation terminates after two decimal places.
This is because it has a fixed and finite decimal representation. The digits "15" represent the whole number part, and the "24" represents the fractional part. Since there is no repeating pattern of digits after the decimal point, 15.24 is classified as a terminating decimal, not a repeating one.
Therefore, it is not a repeating decimal.
Use the remainder theorem to divide 5x^2+9x-2 by x+3. What is the remainder
Answer:
16
Step-by-step explanation:
Given
f(x)=5x^2+9x-2
Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).
Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:
f(x)=5x^2+9x-2
f(-3) = 5(-3)^2 +9(-3) -2
=5(9) - 27 -2

3. Consider the following box plot.
(a) Find the interquartile range.
(b) What percent of values is included in the interquartile range?
Answer:
A) 2.5
B) 50% of the values.
Step-by-step explanation:
A)
The range of data starts at 2.0 and ends at 4.5 (i know it's a bit hard to tell lol), by subtracting 2.0 from 4.5 you get the interquartile range, 2.5.
B)
25% of the values are mentioned in the box plot before the median, and 25% of the values are mentioned after the median in the box plot. This together gives you a sum of 50% of the values. Another way to do it is that outside of the interquartile range is 50% of the values.

The number that is 2 to the left of - 7 on the number line
i on the number line
(c)
The number that is T to the left of 2 on the number line
(D). The number that is 7 to the right of 2 on the number line
Answer:
(D). The number that is 7 to the right of 2 on the number line
Step-by-step explanation:
It could also be the number that is 2 to the right of 7 on the number line. When numbers are added, the distances of each to the origin are laid end-to-end from the origin to the right on the number line.
2+7 can mean that the distance 2 is added to the distance 7, or vice versa. (The commutative property of addition says order does not matter.)

What should be done to x^2+ 15x in order to create a perfect square?
Answer:
Add 225/4 to x^2 + 15x.
Step-by-step explanation:
Take the coefficient of the middle term, 15.
Now divide it by 2, 15/2.
Square that, 225/4.
Add 225/4 to x^2 + 15x.
To create a perfect square, add 225/4 in the quadratic function x²+ 15x.
What is a quadratic equation ?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a quadratic function:
= x²+ 15x
To create a perfect square, add and subtract by 225/4
= x²+ 15x + 225/4 - 225/4
= x²+ 15x + 15²/2² - 225/4
= (x + 15/2)² - 225/4
Thus, to create a perfect square, add 225/4 in the quadratic function x²+ 15x.
