<span>The coefficient of
determination is presented by R</span>²<span> is mostly used in the analysis of regression
where it is the proportion of the variance in the dependent variable that is
predictable from the independent variable. The range of values between the predicted
scores and the actual scores is between 0 to 1. The closer the value to 1, the
greater is the relationship between variables and has lesser errors. For example,
if there is an R</span>²<span> of 0.80, then it means that 80% is predictable. R</span>² can be obtained using excel as trendline or with the use of formula.
I think you need to explain more for one to answer it.
Please give more details and I'll try to help (if this is meant to be a question)
Answer:
1: x > -5
2: n > 4
3: x > -2
Step-by-step explanation:
The domain is the set of all first elements of ordered pairs (x-coordinates).
ratio of 6:10, if you divide both numbers by 2 you get a ratio of 3:5
multiply by 2 you get 12:20
multiply by 1.5 you get 9:15
D is not equivalent
