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.)

help asap if answer is correct and provided explanation i will give brainiest.
Answers
Reason:
6 black out of 4+6+5 = 15 total
6/15 = 0.40 is the experimental probability of selecting black.
Side note: The term "empirical probability" is the same as "experimental probability".
The experimental probability of selecting a black marble will be 0.40. The correct option is C.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.
Probability = Number of favourable outcomes / Number of samples
Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.
Number of favourable outcomes = 6
Number of samples = 4+6+5 = 15
Probability = Number of favourable outcomes / Number of samples
Probability = 6 / 15
Probability = 0.40
Therefore, the probability will be 0.40.

An irregular polygon is shown below:
The area of the irregular polygon is ____ square units.
Answers
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!

Find the ratio of y/x to determine if the table represents a proportional relationship:
Answers
Answer:
From the table, find the ratio between each value of y and its corresponding value of x. y/x = 1/5 = 1/5 y/x = 8/40 = 1/5 y/x = 13/65 = 1/5 So, the ratio between the values of y and and their corresponding values of x is constant. Hence, the relationship represented by the table given above is proportional.

A circle with radius labeled 23 yards
Find the area for the circle (use 3.14 for pi). Show your work. Round to the nearest tenth.
Answers
Answer:
The area of the circle that has a radius of 23 yards will be 1,661.06 square yards.
What is the area of the circle?
It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The radius of the circle is 23 yards. Then the area of the circle is calculated as,
A = π x (23)²
Simplify the equation, then the area of the circle is calculated as,
A = π x (23)²
A = 3.14 x 529
A = 1,661.06 square yards
The area of the circle that has a radius of 23 yards will be 1,661.1 square yards.
