I Literally have NO IDEA what I am doing
Answer:
the answer is A. -.613x+4.142
Step-by-step explanation:
I used desmos (a graphing calculator website) to graph the points and the line. See attachments
Answer:
(a) y = -.613x +4.142
Step-by-step explanation:
You want the equation of the line of best fit for the given data.
Line of best fitThe line of best fit will minimize the sum of the squares of the residuals. Those are the differences between the actual data value and the data predicted by the line.
The slope of the line of best fit is the ratio of the covariance of x and y to the variance of x. The line goes through the point (µx, µy). There are several ways you can arrive at the equation for the line of best fit:
use the linear regression function of a spreadsheet or calculatorfind the slope and intercept from means and variancesuse formulas for the slope and intercept"eyeball" a reasonable line through the plotted data.CalculatorMany graphing calculators, and all spreadsheets, have functions for computing a line of best fit for a data set. The first attachment shows the linear regression function results for a TI-84 work-alike calculator app. It shows you the equation of the line is approximately ...
y = ax +b = -0.613x +4.142 . . . . . . matches the first choice
The second attachment shows the same result achieved using the correlation and mean functions provided by the calculator. Again, it tells you the equation is ...
y = -0.613x +4.142
ChoicesIf you examine the given data, you see that generally as x gets larger, y gets smaller. This tells you the line has a negative slope, eliminating choices C and D.
The point (x, y) = (0, 4) tells you the y-intercept is positive, and near +4. This eliminates choice B.
The only reasonable choice among those offered is choice A.
__
Additional comment
We have not shown the formulas for the parameters of the line of best fit. The usual formulas for variance, covariance, and mean apply. There are a number of different ways these can be calculated, some easier than others, depending on the calculator being used. For a multiple-choice problem like this, the analysis of the choices offers the quickest solution.
The third attachment shows a plot of the data, along with the line of best fit.
(When the offered choices differ from each other by only a few percent, then calculation is needed for choosing the correct one.)

Step-by-step explanation:
26 + 3x + 1 = 180
27 + 3x = 180
3x = 180 - 27
3x = 153
x = 153 / 3
x = 51

Find the amount paid for the loan $4800 at 9.9% for 4 years. Note: The answer must be $8500. PLEASE SHOW YOUR WORK!!!!!
$8500.
is the answer to your question
Your class at school has 18 girls and 12 boys. If your school had the same ratio throughout the whole school and there are 2000 students in the school, how many total girls are in your school?
The ratio of girls to boys in your class is 18 girls : 12 boys, or in fraction form 18/12 or 3/2.
If the school has the same ratio throughout, the ratio of girls to boys in the entire school is 3 girls to 2 boys.
To find the number of girls in the school, you can use the equation:
(number of girls) / (number of students) = (3 girls) / (5 students)
Cross-multiplying, we get:
(number of girls) = (3 girls) / (5 students) * (2000 students)
Simplifying, we get:
(number of girls) = 1200
So, there are 1200 girls in the school.

An irregular polygon is shown below:
The area of the irregular polygon is ____ square units.
Answer:
20 square units
Step-by-step explanation:
you can separate this irregular polygon into 2 rectangles:
Rectangle 1 (bigger): 3 Units X 4 Units = 12 square units
Rectangle 2 (smaller): 2 Units X 4 Units = 8 square units
Add the 2 areas: 12+8 square units = 20 square units
Answer:
20
Step-by-step explanation:
To get the area of this irregular polygon, we have to turn the irrelgular polygon into 2 shapes. (Imagine a line drawn from the corner/wall that separates the unit 1 and 4 units down the bottom of the shape. I don't rlly know how to explain it sorry).
First we calculate the first rectangle which is simple, you just have to multiply! 3x4= 12.
Then for the second one, we have to subtract. Basically, 8 units minus 4 units is equal to 4 units meaning that our lenght is four units. Then 3 units minus 1 unit is equal to 2 units which is our width. (i'm deeply sorry if I couldn't explain it the best) Now we just do 4x2=8.
Now we just add 12 and 8 which gives us 20!

A farmer bought a 60,000 sq. ft. rectangular
field for his livestock. If the field was 300 ft.
long, how wide was the field?
Answer: 200sq. ft
Step-by-step explanation: 60000 divided by 300 is 200
a rectangle's area = base x height
60000 = rectangle area
300 = height
base = 60000 divided by 300
Which of the following equations represents a linear function?
A: x = 3
B: y equals one half x minus 5
C: y equals three fourths x squared
D: 3x − 6 = 4
The solution is, Degree of functions y = x/2 - 5 is one, so, B: y equals one half x minus 5represents a linear function.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
we know that,
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
The degree of polynomials in one variable is the highest power of the variable in the algebraic expression.
The degree of linear function is always one.
Degree of functions y = x/2 - 5, is one.
Hence, B: y equals one half x minus 5represents a linear function.
