Answer: True
Step-by-step explanation:
The pearson’s coefficient and Spearman's rank order coefficient each measure aspects of the relationship between two variables.
They are closely related, but not the same.
Spearman's coefficient measures the rank order of the points. It does not care exactly where they are.
Pearson's coefficient measures the linear relationship between the two, i.e. how well a straight line describes the relationship between them.
Answer:
Value of x for fg(x)=gf(x) at <em>f(x) = 2x²</em> and <em>g(x) = x+1</em> is x = -1/4 .
Step-by-step explanation:
We have, f(x) = 2x² and g(x) = x+1
Now, f(g(x)) = g(f(x))
⇒ <em>2(x+1)² = 2x² + 1</em>
<em>⇒ 2( x² + 2x + 1 ) = 2x² + 1</em>
<em>⇒ 2x² + 4x + 2 = 2x² + 1</em>
<em>⇒ 4x = -1</em>
<em>⇒ </em><em>x = -1/4</em>
