Find the slope of the line that passes through (14, -26) and (15, 14).
tatuchka [14]

Answer:

Slope is 40

Full equation: y=40x-586

Step-by-step explanation:

Slope is y2-y1/x2-x1

14 is x1

-26 is y1

15 is x2

14 is y2

14-(-26)/15-14

40

So the slope is 40

To find the equation

y=40x+b

14=15(40)+b

14=600+b

b=-586

Equation:

y=40x-586

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

5 - 5 = 0

5 - 5 = 0

5 - 5 = 0

5 - 5 = 0

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.
