Answer:
No. Jackson failed to account for possible alternate explanations.
Step-by-step explanation:
Both the watering schedule and the amount of sunlight may be contributors to the result Jackson observed. Without some way to control for these factors, the experiment is inconclusive regarding the contribution to the results that is made by the planting soil.

Answer:
II. One and only one solution
Step-by-step explanation:
Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.
Let assume the equation is given as;
x + 3y = 11 .... 1
x - y = -1 ....2
Using elimination method
Subtract equation 1 from 2
(x-x) + 3y-y = 11-(-1)
0+2y = 11+1
2y = 12
y = 12/2
y = 6
Substitute y = 6 into equation 2:
x-y = -1
x - 6 = -1
x = -1 + 6
x = 5
Hence the solution (x, y) is (5, 6)
<em>Hence we can say the equation has One and only one solution since we have just a value for x and y</em>

Answer:
the graph will describe 13x+15 if the cost per audio book goes up by $1.00.
Step-by-step explanation:
This happens because the coefficient to x is 12 before the change. If the change is the cost per audio book going up by one dollar, the coefficient changes to 13. The initial joining fee is the same ($15.00).
