The 12-meter trailer is 3 meters, 60 cm too long for Darrel to pull

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
