Answer:
Step-by-step explanation:
Given are 3 data sets with values as:
(i) 8 9 10 11 12 ... Mean =10
(ii) 7 9 10 11 13 ... Mean =10
(iii) 7 8 10 12 13 ... Mean =10
We see that data set shows mean deviations as
(i) -2 -1 0 1 2
(ii) -3 -1 0 1 3
(iii) -3 -2 0 2 3
Since variance is the square of std deviation, we find that std deviation is larger when variance is larger.
Variance is the sum of squares of (x-mean). Whenever x-mean increases variance increases and also std deviation.
Hence we find that without calculations also (i) has least std dev followed by (ii) and then (iii)
(i) (ii) (iii) is the order.
b) Between (i) and (ii) we find that 3 entries are the same and 2 entries differ thus increasing square by 9-4 twice. But between (ii) and (iii) we find that
increase in square value would be 4-1 twice. Obviously the latter is less.
Answer:
If a number is <u>negative</u> then the number is less than its absolute value.
Step-by-step explanation:
If a number is <u>negative</u> then the number is less than its absolute value.
You need an answer to get x. like it needs to be
10x+44=100 or something in order to find x
Answer:
26.8°
Step-by-step explanation:
You find the supplementary angle by 180° - 153.2° = 26.8°
It's five sided figure as I have said.. but unfortunately, Europa2443 wont allow me to help you.
