Answer:
Paired t-test
Step-by-step explanation:
paired t–test is used when there is one measurement variable and two nominal variables. The most common design is that one nominal variable represents individual organisms, while the other is "before" and "after" some treatment.
-31x+5 is the same as (-18x-12)-13x+17
To find this add 3 and 1 together. This gives you 4. Then, you subtract 4 from 9. The answer is 5. Therefore, the probability to pull out a pineapple candy would be 5/9.
Hi there! :)
Answer:
Equations 1 and 5.

We can simply each answer choice to find those which have no solution:
1. 6x + 1 = 3(2x - 4)
6x + 1 = 6x - 12
0 ≠ - 13, NO SOLUTION.
2. 2 - 5x = 7x - 12
14 = 12x
x = 7/6. 1 SOLUTION.
3. 4(3 - x) = 2(6 - 2x)
12 - 4x = 12 - 4x
0 = 0. INFINITE SOLUTIONS.
4. 5(x + 2) = 2(x - 4)
5x + 10 = 2x - 8
3x = -18
x = -6. 1 SOLUTION.
5. -4(x + 3) = 4(-x - 1)
-4x - 12 = -4x - 4
0 ≠ 8. NO SOLUTIONS.
Therefore, the only equations with no solutions are equations 1 and 5.
