Answer:
1. Positive, 1+2=3
2. Negative, -1-2=-3
Step-by-step explanation:
If you look at both in a graphing perspective, the point (1,2) is in Quadrant I. likewise, adding 2 to the x-coordinate will also result in the point (3,2), also in Quadrant I, where the x coordinate is positive. The point (-1,2) is in Quadrant II, and adding -2 to the x coordinate keeps it in Quadrant II, where the x-coordinate is negative.
It would be 15 greater than or equal to 14

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
