Answer:
a positive correlation is when both variables move in the same direction. a negative correlation is when the variables move in opposite directions. no correlation is when the variables are not statistically related
Step-by-step explanation:
negative correlation example: As you climb the mountain (increase in height) it gets colder (decrease in temperature).
zero correlation example: the amount of apple juice drunk and level of intelligence
btw you have a good example of positive correlation :) it can also be when both variables decrease

6x + y = 15
-7x - 2y = -10
Answer: x = 4 y=-9
Step-by-step explanation:
Answer:
x = 4
y = -9
Step-by-step explanation:
Isolate a variable from one of the equations ( I chose the first equations cuz it's easy): 6x + y = 15 will be y = 15 - 6x
Substitute the above equation in the place of y in the second equations:
-7x -2(15 - 6x) = -10
-7x -30 + 12x = -10
-30 + 5x = -10
5x = 20
x = 4
To find y-value, substitute the x-value gotten in any equation:
y = 15 - 6(4)
y = 15 - 24
y = -9
Hope this helps!

Solve the system of equations by substitution.
-8x+2y=4
y=4x+2
Answer:
the answer by substitution would be y = 4x+2
Correct answer: Infinite solution because 2 = 2.
Set the first equation equal to y.
-8x + 2y = 4
+8x +8x
___________
2y = 8x + 4
__ ___ __
2 2 2
y = 4x + 2
At this step, you can choose any equation to substitute into the other equation. However, I'm going to substitute the new first equation with the second equation where y is. Solve for x.
y = 4x + 2
4x + 2 = 4x + 2
-4x -4x
____________
2 = 2
So, at this point, we know the system of equation does not have one solution. Thus, when the same number equals the same number, it is an infinite solution.
We can prove this by an online graphing tool. Insert the two equations onto the online graphing tool. If the lines appear to be on the same line, they have infinite solutions. Hope this helps :) Let me know if you have any questions related to this problem!

Christian made smoothies by mixing 2.25 liters of orange juice, 4.75 liters of pineapple juice, and 2.5 liters of grape juice. He then poured equal amounts of mix into 5 different containers for his friends. About how much smoothie did Christian pour in to each container? Please tell me how you got the answer!!!
Answer: He poured about 2 liters into each cup.
Step-by-step explanation: First add 4.75 , 2.25 , and 2.50 which equals 9.5. Divide 5 which then equals 1.9 but since its an estimate you could say 2.
A tetrahedron is a pyramid with a triangular base. Find the volume of the tetrahedron.
L = 3 in W = 4 in H = 11 in
Answer:
Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take as an example to see how the atoms actually bond in tetrahedron. It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.
