Q. What do you mean by inverse relation ? How can I find it out ? ツ

☄ A relation obtained by interchanging the first and second component of each of ordered pair of a given relation R is known as inverse relation of R. It is denoted by \tt{ {R}^{ - 1}}. In other form, if R be a relation from A to V then the relation from B to A is called the inverse relation of R.

Symbolically , if R = { ( x , y ) : x ∈ A , y ∈ B} then \tt{ {R}^{ - 1}} = { ( y , x ) : y ∈ B , x ∈ A }

☏ To be more precise , All you have to do is interchange the first and second component of each of ordered pair of a given relation.

✺ \tt{STUDY \: TIP} :

Answer:

(x+1)^2+(y+1)^2=13

Step-by-step explanation:

Equation of a circle: (x – h)^2 + (y – k)^2 = r^2

center: (-1, -1)

radius: sqrt(6^2+4^2)/2=sqrt(52)/2=2sqrt(13)/2=sqrt(13)

Substitute those values in to get

(x+1)^2+(y+1)^2=13

Which of the following correctly completes the square for: x^2+2x=48
Ket [755]

Answer:

(x+1)²= 49, the answer is B

Step-by-step explanation:

x² + 2x = 48

x² + 2x + (2/2)² -  (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² -  (2/2)²]

(x+1)²= 49, the answer is B

Random samples of size 81 are taken from an infinite population whose mean and standard deviation are 200 and 18, respectively.
TiliK225 [7]

Answer:

d. 200 and 2

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

Mean = 200

Standard deviation = 18

Sample size: 81

Standard error: s = \frac{18}{\sqrt{81}} = 2

So the correct answer is:

d. 200 and 2
