Answer:
A lurking variable is a variable that has an important effect on the relationship among the variables in the study, but is not one of the explanatory variables studied. Two variables are confounded when their effects on a response variable cannot be distinguished from each other.
Answer:
Which one have same variable gather or decrease up
Step-by-step explanation:
2x^2-4.6x^2=1.4x^2
-7x+7x=0
1.4x^2+2<0
x<0
4x-3 ≥ 5
4x ≥ 5+3 (add 3 to both sides)
x ≥ 8/4 (divide both sides by 4)
x ≥ 2
a is the answer.
_____________________
3x-5 ≥ 7
3x ≥ 7+5
x ≥ 12/3
x ≥ 4
b is the answer

Answer:
-7
Step-by-step explanation:
Answer:
Step-by-step explanation:
She stops by (0,0)
She further needs to travel to (5,-4)
Let's calculate the distance using the Distance Formula:
Distance Formula = 
D = 
D = 
D = 
D = 
D = 6.4 units
She needs to travel 6.4 units more.
