The table shows the air pressure in pounds per square inch at different altitudes in thousand feet
Altitude (thousand feet)

Air pressure (pounds per square inch) 12.4 10.2 7 62 52 42 34 26 20
Which scatter plot best represents the data in the table?
A scatter plot which best represents the data in the table is scatter plot B.
What is a scatter plot?A scatter plot is also referred to as scatter chart, scatter diagram or scattergram and it can be defined as a type of graph which is used for the graphical representation of the values of two (2) variables, with the resulting points showing any association (correlation) between the data set.
In this scenario, the altitude (thousand feet) would be plotted on the x-axis of the scatter plot while the air pressure (pounds per square inch) would be plotted y-axis of the scatter plot as depicted in the image attached below.
In conclusion, we can reasonably infer and logically deduce that scatter plot B best represents the data in the table.

Find the range of the function f(x) = x² - 5x for the domain {2, 4, 7).
Range:
By evaluating the function f(x) = x² - 5 · x, the range of the function is {- 6, - 4, 14}.
How to determine the range of the function
In this problem we have a domain, that is, an input set, formed by three natural numbers and a quadratic equation that represents a function that allows us to find the corresponding elements of the range, that is, the output set. The elements of the range are found by evaluating the quadratic equation at each element from domain:
x = 2
f(2) = 2² - 5 · 2
f(2) = 4 - 10
f(2) = - 6
x = 4
f(4) = 4² - 5 · 4
f(4) = 16 - 20
f(4) = - 4
x = 7
f(7) = 7² - 5 · 7
f(7) = 49 - 35
f(7) = 14

Mia borrowed $800 from her brother to start a small business. She applies to sell her products at a vendor fair. The vendor fair requires all businesses to pay a $50 entry fee, plus 10% of their sales.
If Mia sells $1,050 worth of products at the fair, how much money will she earn in total, after paying the vendor fees and repaying her brother's loan?
The money that she earns in total, after paying the vendor fees and repaying her brother's loan is $95.
How to calculate the value?From the information, Mia borrowed $800 from her brother to start a small business and she then applies to sell her products at a vendor fair.
Also, it should be noted that the vendor fair requires all businesses to pay a $50 entry fee, plus 10% of their sales.
The amount that she will earn after selling $1050. worth of product will be;
= $1050 - Amount borrowed - Entry fee - Percentage on sales
= $1050 - ($800) - $50 - (10% × $1050)
= $1050 - $800 - $50 - $105

10x² - (9x + 4x²) + 7 + (5x - 8)
When working with unknowable numbers, we can simplify equations by using the distributive property. If the equation be 10x² - (9x + 4x²) + 7 + (5x - 8) then we get 6x² - 4x - 1.
What is meant by distributive law?The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.
Let the equation be 10x² - (9x + 4x²) + 7 + (5x - 8)
Apply rule: a +(b + c) = a + b + c
7 + (5x - 8) = 7 + 5x - 8
= 10 x²- (9 x + 4 x²) + 7 + 5x - 8
simplifying the above equation, we get
= -(9x + 4x²) + 10x² + 5x + 7 - 8
Subtract the numbers: 7 - 8 = -1
= -(9x + 4x²) + 10x² + 5x - 1
Apply the distributive law: -(a + b) = -a - b = 0
-(9x + 4x²) = - 9x - 4x²
= -9x - 4x² + 10x² + 5x - 1
Add similar elements:
-4x² + 10x² = 6x² = -9x + 6x² + 5x - 1
simplifying the above equation, we get
= 6x² - 9x + 5x - 1
Add similar elements: -9x + 5x = -4x
= 6x² - 4x - 1
Therefore, by simplifying the equation, we get 6x² - 4x - 1.

how to divide 306.67 and 254.00 i rlly need help i have a project due tmr.
The value of the quotient is 1.207
How to evaluate the quotient?The statement is given as
Divide 306.67 and 254.00
Rewrite the above statement properly
So, we have
Divide 306.67 by 254.00
Rewrite the above statement as a quotient expression
So, we have
306.67/254.00
Express 306.67 as 254.00 + 52.67
So, we have
306.67/254.00 = (254.00 + 52.67)/254.00
Evaluate the quotient of 254 and 254
So, we have
306.67/254.00 = 1 + 52.67/254.00
Evaluate the other quotient
So, we have
306.67/254.00 = 1 + 0.207
306.67/254.00 = 1.207

a) As per the given percentage, the number of registered voters in the town who cast the votes are 155,952.
b) Reese claim is incorrect. The number he mentioned as registered voters is greater than the actual number of registered voters..
Percentage:
A percentage is a number or ratio which can be expressed as a fraction of 100.
For example, 57% can be written as 57/100.
Given,
The register voters and other in the town cast their vote on the election day.
a. In that particular town, 273,600 votes were cast in an election. And there are 57% of those who were registered voted.
Here we need to find how many registered voters are there in the town.
b. Reese claims that there are 60% of the registered voters cast 273,600 votes, there would be fewer registered voters than above.
Now we have also need to find whether his statement is correct or not with the reason.
Let x be the total number of registered voter who cast the vote.
From the given details, we know that, there are 273,600 voters are cast.
And 57% of them are registered voters.
So, it can be calculated as follows,
=> x = 273600 of 57%
=> x = 273600 x 57%
=> x = 273600 x 57/100
=> x = 2736 x 57
=> x = 155, 952
Therefore, there are 155,952 registered voter in the town who cast the vote.
Based on these calculation we know that, Reese claims is incorrect because there the number of registered voters is 155, 952 which is not equal to the number he mentioned.

Dividing Decimals: Rounding the quotient, 0.03 divided by 0.148 =
The quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.
According to the question,
We have the following information:
0.03 is divided by 0.148
And it can be simply expressed as 0.03/0.148
Now, we have the quotient as:
0.2027
Now, when rounding off the numbers we know that the digits from where we are rounding off we look at the right next to that digit and when that digit is greater than 5 then the digit should be increased by 1 and when that digit is less than 5 then the digit should be the same.
So, we will round it off by taking the underlined digit to be next to first 2:
So, the digit is 0.
Butt if we are taking the underlined digit as 2 to be the next 2 then the digit next to it is 7 which is greater than 5.
Then, we have:
0.2
Hence, the quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.

The gcf of 15 and 36 is 3 and 15 + 36 by distributive property is 51.
What is gcf?
The gcf(greatest common factor) is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.
What is distributive property?
According to the distributive property, multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together. A (B + C) = AB + AC.

y = -2x + 9y = 2x - 3How to find the equation of a line?The equation of a line can be found as follows:
Using the slope intercept form,
y = mx + b
where
m = slopeb = y-interceptTherefore, let's find the slope using the table.
(-4, 13)(-3, 11)
m = 11 - 13 / -3 + 4
m = - 2 / 1
m = -2
Let's find the y-intercept using (-4, 13)
13 = -2(-2) + b
13 - 4 = b
b = 9
Therefore, the equation of the line is y = -2x + 9
Using the second table,
(0, -3)(2, 1)
m = 1 + 3 / 2 - 0
m = 4 / 2
m = 2
y-intercept = b = -3
