Answer:
(a)
degree is 4
it is binomial
(b)
degree is 2
it is trinomial
(c)
degree is 3
it is monomial
Step-by-step explanation:
(a)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 4
Number of terms:
we can see that there are two terms
so, it is binomial
(b)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 2
Number of terms:
we can see that there are three terms
so, it is trinomial
(c)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 3
Number of terms:
we can see that there are one term
so, it is monomial
Answer:
A. positive slope.
Step-by-step explanation:
In the least square linear regression of Y on X, the straight line of best fit is given by,
------------------(1)
[where is the estimated value of Y]
Clearly, here,
Slope pf the line = ---------------------------------(2)
Y- intercept = -----------------(3)
and,
X - intercept = ----------------(4) [putting in (1) and taking the value of X]
So,
since
[since or will result in a degenerate distribution, hence these cases are discarded]
so, correlation coefficient = > 0 implies
A. positive slope. [as evident from (1)]
clearly from (3) and (4) all the other options are false.
