The outlier, 78, is removed from the data set shown.23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78

How does this affect the range?

A.) The range is decreased by 4.

B.) The range is decreased by 16.

C.) The range is decreased by 22.

D.) The range is decreased by 33.

Answers

An outlier of a set of data is a data value that is too small or too large compared to other values in the set of data. Range of a set of data is the difference between the largest data value and the smallest data valu in the set of data. Range of 23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78 is 78 - 23 = 55 When the outlier 78 is removed, the range of the data set 23, 23, 25, 27, 34, 34, 35, 41, 45, 45 is 45 - 23 = 22 Thus, when the outlier 78 is removed, the range of the data set decreases by 55 - 22 = 33. Therefore, the correct answer to the question "The outlier, 78, is removed from the data set shown. 23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78 How does this affect the range?" is "The range is decreased by 33." (option D).

The equation of a circle is (x+10)^2+(y-4)^2=100 What is the center and radius of the circle.
1.) Center-10,4); Radius: 10
2.) Center: (-10,4); Radius: 10,000
3.) Center10,-4);Radius: 10
4.) Center10,-4);Radius: 10,000

Answers

Answer:

Correct option is:

1.) Center: (-10,4); Radius: 10

Step-by-step explanation:

The equation of the circle centered at (a,b) and radius r is:

$(x-a)^2+(y-b)^2=r^2$

Here, we are given a equation:

$(x+10)^2+(y-4)^2=100$

On comparing this equation with the above equation, we get

a= -10

b=4

and r=10

Hence, Center of circle= (-10,4)

and Radius=10

Hence, Correct option is:

1.) Center: (-10,4); Radius: 10

Answers

It's y=kx. But 'k' is any constant. So my 'k' can easily be 1/(your k). The key is that when 'x' or 'y' increases by some factor, the other one also increases, by some constant multiple of the same factor. If so, then they're proportional.
