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
Step-by-step explanation:
Paralle lines have the same slope.
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have
Convert to the slope-intercept form:
<em>subtract 9 from both sides</em>
<em>divide both sides by 5</em>
Each of the answers to choose from is not the line equation sought.
The equation:
where <em>b</em> is any real number.

Step-by-step explanation:
He needs 13 cans of paint.
The lateral area is given by the area of 5 rectangles, whose dimensions are 15 by 5:
5(15)(5) = 375
Divide this by 30:
375/30 = 12.5 ≈ 13
