<span>So the question is what does the point (-3, -5) correspond to on the graph of the function. If we have a point on a graph in the Cartesian coordinate system then that point consists of coordinates (x, y). In other words, y=f(x) and x so (x, f(x)) where x is a x-coordinate and y=f(x) is y-coordinate. So if we have a point (-3, -5) the corresponding coordinates are x=-3 and y=f(x)=-5. So it must be true that y=f(-3)=-5. So the correct answer is a. f(-3)=-5.</span>

The dot plot displays the number of marshmallows added to hot cocoa by several kids. What is the MAD of the data represented in

Pie

Mean absolute deviation (MAD) of the data set indicates the average distance of all elements from mean of the data set.

MAD of the data represented by dot plot in the picture will be Option A.

Elements in the given dot plot are,

3, 4, 5, 5, 5, 5, 5, 5, 6, 7

Steps to be followed for the mean absolute deviation of this data set.

Find the mean of the data set
Find the absolute distance of each element from the mean
Find the average distance of all the elements which will be MAD of the data set.

Step - 1 :

Mean of the data set = $\frac{\text{Total of the data}}{\text{Total number of elements}}$

= $\frac{3+4+5+5+5+5+5+5+6+7}{10}$

= $\frac{50}{10}$

$=5$ (As shown on the dot plot)

Step - 2 :

Absolute distance of each element from the mean of the data set,

3 - 5 = |-2| = 2

4 - 5 = |-1| = 1

5 - 5 = 0

6 - 5 = 1

7 - 5 = 2

Step - 3 :

Average of the absolute distance = $\frac{2+1+0+0+0+0+0+0+1+2}{10}$

= $\frac{6}{10}$

= 0.6

Therefore, Option A will be the correct option.

Is y=1/2+2 linear? and how do you know just by looking at the equation?

saul85 [17]

Answer:

No, it is not

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
