Answer:
4/16 because 5/20 is equivalent to 1/4. 4/16 is also equivalent to 1/4
Step-by-step explanation:
Divide 5/20= 1/4
Multiply 4 times the numerator and the denominator:
4 × 1 = 4
4 × 4 = 16
so we know 4/16 is equivalent to 5/20
Identity property of zero states that the sum of 0 and any number is that number.
You can solve with the formula for cuadratic equations:
x=−b±√b2−4ac

1) find the mean,
20+10+30+20+50+30+40+20/8= 27.5
2) Find the distance of each value from that mean
20- 7.5
10- 17.5
30- 2.5
20-7.5
50- 22.5
30- 2.5
40- 12.5
20- 7.5
3) Find the mean of those distances
7.5+17.5+2.5+7.5+22.5+2.5+12.5+7.5/8=10
The Mean absolute deviation for this data set is 10.
