Answer:
4/5 or 0.8
Step-by-step explanation:
Answer:
must also be positive
Step-by-step explanation:
The sign of the correlation coefficient indicates whether the fitted line is sloping upwards or downwards, so it should be consistent with the sign of the slope of the fitted line. so if the correlation line is poitive so should the regression line
Answer:
22
Step-by-step explanation:
17+5=22
Answer: 11x^2
Step-by-step explanation:
I suppose that the options are:
a) 9/x
b) 11x^2
c) 20x^9-7x
d) 20x -14
First, a polynomial is something like:
aₙx^n + .... + a₂*x^2 + a₁*x^1 + a₀*x^0
Where n is the degree of the polynomial, the therms a are the coefficients, and aₙ is the leading coefficient.
Depending on the number of terms of the polynomial, it takes different names.
If we have only one term, it is called a monomial, if it has two terms, it is called a binomial, and so on.
So if we want to find a monomial, then we need to look at the options with only one term.
The options with only one term are options a and b.
But option a is a quotient (we have a negative power of x: 9/x = 9*x^-1)
So this is not a polynomial, then the correct option is option b.
