Someone please.. help me in this please I don’t want to fail it..please

So it wants you to first find the mean (average) of the data set, then find the distance everything is from the mean (average).

Step-by-step explanation:

3+5+9+14+16+18= 65

65 divided by the amount of numbers you put in (6) = 10.83 rounded to the nearest hundreth

So now we know the mean (average) now we need to see how far away each number is from the mean (average).10.83-3 is 7.83. 10.83-5 is 5.83. 10.83-9 is 1.83. 10.83-14 is -14.17, but -14.17 would be a normal 14.17 because it wants the absolute value. 10.3-16 is -5.17 (of course keep it as a positive), and finally 10.83-18 is -7.17 as a positive. Now for the mean absolute value of the data they likely mean from 0, so it would be 10.83.

Hope it helped and wasn't too confusing :)

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
