Basically the graph of this, would simply be a horizontal line, where although the X values change, the y coordinate is the same for all of them.
For instance certain ordered points can be - (-1,4), (0,4), (1,4), (2,4) ...
Answer:
y = -x - 6
Step-by-step explanation:
y = -x + b
2 = -1(-8) + b
2 = 8 + b
-6 = b
Answer:
The standard deviation of a probability distribution is a measure of variability of the distribution.
Step-by-step explanation:
We have been given an incomplete statement. We are asked to complete the given statement.
We know that standard deviation is measure of variability or dispersion of a set of data values.
It tells up how much a data point is spread out from the average or mean of the data set.
Therefore, option A is the correct choice.

a) Rectangles are similar
b) 1 : 9
c) No volume
Step-by-step explanation:
Step 1 :
Given
The length and width of rectangle1 is x and y
The length and width of rectangle2 is kx and ky
Step 2 :
a)
2 rectangles are similar when the sides of the rectangles are proportional
Since here we have the sides of rectangle 2 obtained by multiplying each side of the first rectangle by a non zero constant term , the 2 given rectangles are proportional
Step 3 :
b)
Area of rectangle1 is x * y
Area of rectangle is 3x * 3y = 9xy (given k = 3)
Ratio of the areas is xy : 9 xy = 1 : 9
Step 3 :
Given k = 2
There is no volume for a 2 dimensional figure
