Answer:

\bar X = \frac{0.4+0.2+0.4+0.6}{4}= 0.4

Now we can calculate the absolute deviations from the mean for each value:

|0.4-0.4|=0

|0.2-0.4|=0.2

|0.4-0.4|=0

|0.6-0.4|=0.2

And adding these 4 values and dividing by 4we got the MAD on this case:

MAD = \frac{0+ 0.2+0 +0.2}{4}=0.1

Step-by-step explanation:

We have the following dataset given:

0.4,0.2,0.4,0.6

In order to calculate the MAD we need to calculate the sample mean first with this formula:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

Replacing we got:

\bar X = \frac{0.4+0.2+0.4+0.6}{4}= 0.4

Now we can calculate the absolute deviations from the mean for each value:

|0.4-0.4|=0

|0.2-0.4|=0.2

|0.4-0.4|=0

|0.6-0.4|=0.2

And adding these 4 values and dividing by 4we got the MAD on this case:

MAD = \frac{0+ 0.2+0 +0.2}{4}=0.1

amid [387]

Answer:

2010\leq{x}\leq{2019}

Step-by-step explanation:

  • The function f(x) shows the number of cell tower users after "x" years from the year 2010.
  • Then, the dependent varible of the function f(x) are the number of cell tower users after x years from 2010, and  the independent variable of this function, "x", are the years that have passed since 2010, included 2010.
  • This means that the independent variable should take the values of the years from 2010, which represent the domain (values that x variable can take), that are all the years between 2010 and 2019 (which is the present year).
