Step-by-step explanation:
step 1. (-0.4)(0.16) = -0.064
step 2. (0.625)(-0.08) = -0.05
step 3. -1.2(-5.1) = -6.12
The number in the parentheses is the rate of change. Because this number is less than 1 it is a decrease, so it is a decay.
The percent decrease is 1 - 0.63 = 0.37 = 37% decrease
The answer is high variability
The ratio is 4:5
Divide both terms by 4
16/4 =4
20/4=5
