The dot plot below shows 6 data points with a mean of 16.

what is the absolute deviation at 19?
3
4
7
8

The absolute deviation at 19 is 3.

Step-by-step explanation:

The absolute and mean absolute deviation show the amount of deviation (variation) that occurs around the mean score.

Since we are only interested in the deviations of the scores and not whether they are above or below the mean score, we can ignore the minus sign and take only the absolute value, giving us the absolute deviation.

We are asked to find the absolute deviation at 19.

the given mean is 16.

Hence, the deviation is:

19-16= -3.

Hence the absolute deviation at 19 is |-3|=3.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
