Answer:
D) 2
Step-by-step explanation:
write 8 in exponential form which is 2^3
now simplyfy the root which equals 2
2 is the answer.
15) 5/8
16)21.16 meters
17)C
the common ratio is 1/5
the scale factor or start value is 500
distance left to run = total distance - distance already run
= 3 miles - (13/7) miles
= 21/7 miles - 13/7 miles = 8/7 miles
The mean absolute deviation of a set of data is the average distance between each data value and the mean.
The mean is (20+25+30+30+45)÷5=30
( |20-30|+|25-30|+|30-30|+|30-30|+|45-30| )÷5=6
The mean absolute deviation is 6.
