<span>The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
- </span>(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15<span>The "median" is the "middle" value in the list of numbers.
- </span>13, 13, 13, 13, 14, 14, 16, 18, 21...
So the median would be 14.<span>The "mode" is the value that occurs most often. If no number is repeated, then there is no mode for the list.
- So the mode would be 13 
</span>The "range" is just the difference between the largest and smallest values.
-    21-13= 8

I hope this helps you.

Answer:

Please check the explanation.

Step-by-step explanation:

Given that

|v|=38

Ф = 120°

<u>Finding the horizontal component</u>

The horizontal component can be obtained using the formula

Vx = |v| cos Ф

     = 38 cos 120°

     = 38 (-0.5)

      = -19

Thus, the  horizontal component is:

Vx = -19

<u>Finding the vertical component</u>

The vertical component can be obtained using the formula

Vy = |v| sin Ф

    = 38 sin 120°

    = 38 (0.86)

    = 32.68

Thus, the vertical component is:

Vy = -19

  • A vector 'v' with magnitude |v| and direction Ф can be written as:

v = |v| cos Ф i + |v| sin Ф j

As

|v|=38

Ф = 120°

Thus, the vector is

v = 38 cos 120° i + 38 sin 120° j

or

v = -19 i + 32.68 j
