Answer:
There appears to be a difference between the pulse rates from samples of adult males and females. The average pulse rate of males is 63.75 while that of females is 75.875.
Coefficient of Variation (male) = 33.44%
Coefficient of variation (female) = 28.35%
Step-by-step explanation:
Mean (male) =
Mean (female) =
Standard Deviation (male) =
Standard Deviation (female) =
Coefficient of Variation =
For male, CV = %
For female, CV = %
Comparison : Pulse rates of males has more variability than that of females since it has a greater coefficient of variation.
To simplify this expression we need, at first, to find like terms.
<span>-3x+5y-2+7x-8y</span><span>-3x+5 = (</span>-3x+7x)+ (5y-8y) -2+5 = 4x + 3y +3
4x + 3y +3 is the answer.
