D.4 he should apply 4 treatments to each of the groups
Assuming that Jupiter and Earth are similar
linear sale factor=(diameter of Jupiter) /(diameter of earth)=11
thus:
diameter of earth=(diameter of Jupiter)/(linear scale factor)
=88000/11
=8000 miles
The diameter of earth is 8000 miles
Answer:
Total Profit = P(a,b) = ($0.40a) + ($0.40b), where a = # of apples sold and b = # of bananas sold.
There is the equal values method, so you can do:
x-4 = 4x-10 (remove x from both sides)
-4 = 3x -10 (add ten to both sides)
6 = 3x (devide by 3x)
2 = x
Check: (by plugging it into the equation)
y = 2-4 and y = 8-10
y = -2 and y = -2
that's matches so it is correct...
YOUR ANSWER IS:
(2, -2)
I hoped I helped sort things out, and have a great day!
