Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. Statisticians typically use the least squares method to arrive at the geometric equation for the line, either though manual calculations or regression analysis software. A straight line will result from a simple linear regression analysis of two or more independent variables. A regression involving multiple related variables can produce a curved line in some cases.

Calculate the area of the parallelogram to determine how much material should be purchased. Be sure to explain how to decompose this shape into rectangles and triangles. Describe their dimensions and show your work.
Answer:
oh
Step-by-step explanation:
I can't really give you the exact answer for this question. However, I can give you the formulas to solve this question.
FORMULAS
Area of a parallelogram - b x h
Area of a triangle - b x h ÷ 2
Area of a rectangle/square - l x w
REMEMBER:
To square (²) the final total/result.A parallelogram is usually 2 triangles and a square, or you can think of it as 2 squares.Hope this helped. :)

An object is moving east, and it’s velocity changes from 65 m/s to 25 m/s in 10 seconds.which describes acceleration
Answer:
The acceleration of object is -4 ms⁻²
Step-by-step explanation:
We are given:
Initial Velocity = 65 m/s
Final Velocity = 25 m/s
Time t = 10 seconds
We need to find acceleration.
The formula used to find acceleration is: [tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}[/tex]
Putting value in the formula and finding acceleration:
[tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}\\Acceleration=\frac{25-65}{10}\\Acceleration=\frac{-40}{10}\\Acceleration=-4\:ms^{-2}[/tex]
So, acceleration of object is -4 ms⁻²
Of the 300 television sets sold at an electronics store last month, 90 were flat screen TV's. What is the ratio of flat-screen TV's to other TV's sold last month?
I don't know how to do this. I would appreciate some help. thanks!!
Answer:
300 television sets total
300 - 90 flat screens = 210
flat screens 90:210 other TVs
now divide each side of the ratio by a common factor to simplify. I'm going to use 30
flat screens 3:7 other TVs
this cannot be simplified any further so the ratio is
flat screens 3:7 other tvs

Answer:
6
Step-by-step explanation:
Step 1: g(6) = 4 - 2 x 6
Step 2: g(6) = 4 - 12
Step 3: g(6) = -8
Step 4: g(9) = 4 - 2 x 9
Step 5: g(9) = 4 - 18
Step 6: g(9) = -14
(Final Step) Step 7: g(6) - g(9) = -8 - (-14) = 6

Answer:
For the first question, the answer is 32 oz.
For the second question, the answer is 16 oz.
Step-by-step explanation:
For the first one, since there are 16 ounces in a pound, we can assume that since she has 3 pounds of fudge, she would have 48 ounces. She then eats one pound of fudge, which means we subtract 16 from 48 getting us to 32 ounces.
For the second question, it states that she gives one half of her fudge to her sister. 2 times 1/2 is 1, and since there are 16 ounces in a pound, she therefore gave 16 ounces of fudge to her sister.
Answer:
1. 32 ounces
2. 16 ounces
Step-by-step explanation:
Question 1First, you have to subtract. The equation for the subtraction is 3-1 because the student took 1 pound of fudge away from the 3 pounds she already has. And 3-1 equals 2. Now, you have to convert 2 pounds to ounces. Lastly, multiply 2 by 16 as it says in the picture (it says 16 ounces equals 1 pound). The answer to this equation can be expressed as 32 or 32 ounces.
Question 2First, you have to take information from the previous question which is that she has 2 pounds of fudge left. Then, she gives [tex]\frac{1}{2}[/tex] of the fudge to her sister, so you have to divide 2 by [tex]\frac{1}{2}[/tex] which is 1. Now, you have to express 1 as ounces as shown in the picture. You just have to multiply 1 by 16 which is 16. Therefore the answer can be expressed as 16 or 16 ounces.
