Answer:
Matched pairs
Step-by-step explanation:
Here each athelete's time to complte 20 shuttle runs is to be compared with his/her time to complete the obstacle course is to be compared to determine their association
Inference for regression will be sutiable if their association is already known or if they can be realted via mathematical model.
Independent samples method can't be used as outcome of one experiment is to be matched with outcome of other experiment
Answer:
A (4.18
Step-by-step explanation:
You do 2.2 (base) x 3.8 (height) and divide it by 2
So,
For number one, there will be an infinite number of solutions, as there are two placeholders.
3x - 2y = 6
It seems we can use the intercept method.
3x - 2(0) = 6
3x = 6
Divide both sides by 3
x = 2
This is one solution: (2,0)
3(0) - 2y = 6
-2y = 6
Divide both sidees by -2
y = -3
This is another solution: (0,-3)
You should now be able to draw the line.
If you want intercept form for this equation, just manipulate the equation in order to get the y = mx + b form.
Subtract 3x from both sides
-2y = -3x + 6
Divide both sides by -2
For the second problem, simply manipulate the equation.
Distribute
Subtract 2x from both sides
Add 6 to both sides
For the third problem, do the same thing.
We must first multiply both sides by 4.
Distribute
Subtract 4x from both sides
Add 3 to both sides
Divide both sides by 2
