Answer:
perimeter of rectangles = 2 ( l + b)
34 = 2 ( x + 2 + 3x - 4 )
34 = 2 ( 4x - 2 )
34 = 8x - 4
38 = 8 x
38/ 8 = x
thus , x = 4.75 inches
Answer:
mean lean body mass of the lean monkeys = 8.4kg
mean lean body mass of the obese monkeys = 10.4kg
Step-by-step explanation:
a) Mean = Sum of Body mass/number of body mass
For lean monkeys, mean = (6+7.5+9.2+9.7+9.1+9.1)/6
Mean = 50.6/6
Mean = 8.4
b)
for obese monkeys, mean = (8+9.1+10.3+12+11.9+11.2)/6
Mean = 62.5/6
Mean = 10.4
