For the following questions answer them individually

Question 41

The coefficient of Non-determination is equal to -

Video Solution

Question 42

If the two lines of regression are perpendicular to each other then the value of coefficient of correlation is -

Video Solution

Question 43

The number of terms in the expansion of the binomial distribution $$(a+b)^{4}$$ is -

Video Solution

Solution

The number of terms in the expansion of $$\left(a+b\right)^n$$ is n+1

So the number of terms in the expansion of $$\left(a+b\right)^4$$ will be 4+1 = 5

Question 44

What is the integral of $$\cosec^{2} x$$ with respect to $$x$$?

Video Solution

Solution

The integral of $$\operatorname{cosec}^{2x}$$ with respect to x is -cot(x) + C, where C is the constant of integration. This integral can be obtained by using the trigonometric identity:

$$\operatorname{cosec}^{2x}$$ = 1 + cot^2(x),

and then integrating term by term. So, integrating 1 gives x, and integrating cot^2(x) gives -cot(x). Adding the constant of integration, we get -cot(x) + C.

Question 45

For the set A = {3, 4}, find Power Set P(A)

Video Solution

Solution

The power set is a set which includes all the subsets including the empty set and the original set itself. It is usually denoted by P. Power set is a type of sets, whose cardinality depends on the number of subsets formed for a given set. If set A = {x, y, z} is a set, then all its subsets {x}, {y}, {z}, {x, y}, {y, z}, {x, z}, {x, y, z} and {} are the elements of power set, such as:

Power set of A, P(A) = { {x}, {y}, {z}, {x, y}, {y, z}, {x, z}, {x, y, z}, {} }

For the set A = {3, 4},

Power Set P(A) = $$\left\{\phi ,{3}, {4}, {3,4}\right\}$$

Question 46

If the international terms of trade settle at a level that is between each country's opportunity cost, then

Video Solution

Question 47

Haberler's theory of opportunity cost is represented by

Video Solution

Question 48

An exchange rate which also takes into account the relative prices of products in the countries being compared is known as -

Video Solution

Question 49

Which of the following is consistent with the idea of expansionary fiscal policy?

Video Solution

Question 50

Find the mi.nor of element 8 in the determinant $$\triangle = \begin{bmatrix}1 & 4 & 6 \\2 & 5 & 9\\8 & 7 & 12 \end{bmatrix}$$
