Hello,
answer is C

m=-40h+130
Indeed
 A=(1/2,110)
B=(3,10)

y-10=(10-110/(3-1/2)(x-3)
==>y=-100/(5/2)*(x-3) +10
==>y=-40x+120+10
==>y=-40x+130
(or m=-40h+130 )

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.

Question 16
den301095 [7]

Answer:

Statement B and D are correct.

Step-by-step explanation:

The number of minutes Gabriel spends grading essays can be presented as a function: f(x) = 4x, where x is the number of graded essays and 4 is the number of minutes Gabriel spends on grading each essay.

By definition, domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

So in this case, domain of f(x) is the set of all values of x which is an integer going from 0 to 105. Statement D is accurate.

Range of f(x) is the set of all values that f takes and can be calculated by multiplying 4 with (0,105), equal (0,420). Statement B is accurate.
