Answer:

4

Step-by-step explanation:

  1. Add up your data. 3+13+11+5=32
  2. Divide the sum by the number of data you have. In your case you would divide 32/4/
  3. This will give you 8, which is your mean. Now, subtract 8 from each value and put the difference to its absolute value.
  4. Now, add up each of these values  (5+5+3+3=16), then divide by 4. This will give you an answer of 4.

Hope this helps! Have a great day :)

Option D: The distance between the two points is 13 units

Explanation:

It is given that the two points are (-5,-2) and (8,-3)

We need to determine the distance between the two points.

It is also given that the distance between the two points can be determined using the formula,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substituting the points (-5,-2) and (8,-3) for the coordinates (x_1,y_1) and (x_2,y_2)

Thus, we get,

d=\sqrt{(8-(-5))^2+(-3-(-2))^2}

Simplifying, we have,

d=\sqrt{(8+5)^2+(-3+2)^2}

Adding the terms, we get,

d=\sqrt{(13)^2+(-1)^2}

Squaring the terms, we have,

d=\sqrt{169+1}

Adding the terms, we get,

d=\sqrt{170}

Simplifying and rounding off the value to the nearest tenth, we have,

d=13.0 \ units

Hence, the distance between the two points is 13 units.

Therefore, Option D is the correct answer.
