A relatively large correlation coefficient, such as the 0.87 given here, indicates a direct proportion relationship between two variables. Here, as baby gains weight, smart phone pricing increases. Note that this is NOT a causal relationship.
32 because 32 x 100 = 3,200
B. rational means it does not go on forever.
With parallel lines, they will never touch one another. Therefore, there shouldn't be any solution.
First we need to understand that the sum of adjacent angles on a straight line is 180°,meaning that when all the angles are added up the answer would be 180°
Here's how we can set up the equation:
2x+100°=180°
2x=80°
x=40°
Thus the answer is 40°
Again,hope it helps!
