Answer:

The correct option is A) Once an individual is​ selected, the individual cannot be selected again.

Step-by-step explanation:

Consider the provided statement.

Without​ replacement mean each population sample unit has only one opportunity in the sample to be chosen.

For example:

If a bag contains 5 red and 3 white ball and you randomly select a white ball, the probability of selecting the white ball is 3/8.

Now if the experiment is done by without replacement that means the white ball (which you have selected) is no longer the part of the sample space.

Hence, we can say that once an individual is​ selected, the individual cannot be selected again.

Thus, the correct option is A) Once an individual is​ selected, the individual cannot be selected again.

Answer:

2. it's a rectangle so Each pair of co-interior angles are supplementary, because two right angles add to a straight angle, so the opposite sides of a rectangle are parallel. This means that a rectangle is a parallelogram, so: Its opposite sides are equal and parallel. Its diagonals bisect each other.

Apply green’s theorem to evaluate the integral 3ydx 2xdy
Ne4ueva [31]

The value of the integral 3ydx+2xdy using Green's theorem be - xy

The value of    \int\limits_c 3ydx+2xdy  be -xy

<h3>What is Green's theorem?</h3>

Green's theorem relates a line integral around a simple closed curve C to a double integral over the plane region D bounded by C.

If M and N are functions of (x, y) defined on an open region containing D and having continuous partial derivatives there, then

\int\limits_c Mdx+Ndy = \int\int\〖(N_{x}-M_{y}) \;dxdy

Using green's theorem, we have

\int\limits_c Mdx+Ndy = \int\int\〖(N_{x}-M_{y}) \;dxdy ............................... (1)

Here N_{x} = differentiation of function N w.r.t. x

          M_{y}= differentiation of function M w.r.t. y

Given function is: 3ydx + 2xdy

On comparing with equation (1), we get

M = 3y, N = 2x

Now, N_{x} = \Luge\frac{dN}{dx}

               = \frac{d}{dx} (2x)

              = 2

and, M_{y} = \Huge\frac{dM}{dy}

             = \frac{d}{dy} (3y)

             = 3

Now using Green's theorem

= \int\int\〖(2 -3) dx dy

= \int\int\ -dxdy

= -\int\ x dy

=-xy

The value of  \int\limits_c 3ydx+2xdy  be -xy.
