Answer:

a) 1.8

b) 11.8

c) 23.6

mean: sum of numbers/total numbers

<h3 /><h3>Part A</h3>

⇒ mean: (2.4+1.6+3.2+0.3+1.6)/5 ⇒ 9/5 ⇒  <u>1.8</u>

<h3>Part B</h3>

If all the data's are increased by 10

{12.4, 11.6, 13.2, 10.3, 11.5}

Then mean ⇒ (12.4+11.6+13.2+10.3+11.5)/5 ⇒ <u>11.8</u>

<h3>Part C</h3>

if the new data doubled, the mean will be double

11.8 * 2 = <u>23.6</u>

3. n=30/3

third would be (3,10)

4.

n=30/4

You can calculate the distance between two point using this fomula: 

√(x_2-x_1)^2+(y_2-y_1)^2


If you insert you values you get:
