The smaller the magnitude of the correlation, the weaker the correlation. The magnitude of -0.25 is 0.25, the smallest correlation magnitude.
Given inequality: 2y−x ≤ −6
Option-1 : (-3,0)
2×0 - (-3) = 0 + 3 = 3 > -6
Not satisfied
Option-2 : (6,1)
2×1 - 6 = 2 - 6 = -4 > -6
Not satisfied
Option-3 : (1, -4)
2×(-4) - 1 = -8 - 1 = -9 < -6
Satisfied.
Thus, (1, -4) is a solution.
Option-4 : (0, -3)
2×(-3) - 0 = -6 - 0 = -6 = -6
Satisfied.
Thus, (0, -3) is a solution.
Option-5 : (2, -2)
2×(-2) - 2 = -4 - 2 = -6 = -6
Satisfied.
Thus, (2, -2) is a solution.
Solutions are: (1, -4), (0, -3) , (2, -2)
Answer:
4 dollars / yard.
Step-by-step explanation:
Formula
Cost per yard = Total Dollars paid/ yards of fabric
As a decimal 1/4 = 0.25
Givens
Total dollars paid = 13
Total yards of fabric 3.25
Solution
cost per yard = 13 / 3.25
Cost per yard = 4 dollars per yard
