Answer:
Option D is correct.
Step-by-step explanation:
Regression analysis determines the relationship between 2 or more variables by examining the influence of independent variables on a dependent variable.
Few requirements for regression analysis are like - quantitative data condition, the outlier condition, error independence etc.
The following is not a requirement for regression analysis:
D:The method for regression analysis line is not robust. It is seriously affected by a small departure from a normal distribution.
Answer:
substitution
Step-by-step explanation:
We assume the two equations are ...
You are given an expression for x. Using that in the second equation will result in an immediate solution for y.
... 2(2y+4) -3y = 11 . . . . . substituting 2y+4 for x
.. y +8 = 11
... y = 3
... x = 2·3 +4 = 10
The solution is (x, y) = (10, 3)
Answer:
Range: (-∞, 0]
General Formulas and Concepts:
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:
(-∞, 0] or y ≤ 0
Answer:
The answer would be 0.99/1 pound
Step-by-step explanation:
An appropriate order for drawing a hexagon is ...
- Use the circle's radius to set the width of the compass.
- Draw a circle using the compass.
- Add a point on the circle.
- Place the point of the compass on the point most recently drawn on the circle.
- Create an arc with the compass that intersects the circle.
- Mark the intersection with a point.
- Repeat the previous step 4 times. [meaning steps 4–6]
- Connect consecutive points with the straightedge.

<em>Comment on this construction</em>
A lot of math is much more understandable if you have real-life experience with physical objects. In geometry, there is really no substitute for actually doing these steps using a compass and straightedge.
One of the things you learn by doing is that you need to be very precise when you're following the process. Otherwise, your hexagon comes out somewhat irregular.
You also find there are other methods (perhaps more accurate and requiring less work), involving symmetry and the center of the circle.
