The number could be several different ones. Are you sure that's exactly what the problem says? If not, I'm going to ask you write the entire problem. If not, then whoever made it did not give enough information for there to be an absolute answer. I'm sorry I couldn't help you, but I really hope I can with more information.
Answer:
Option A
Step-by-step explanation:
Positive correlation describes a relationship between two variables where both variables move in the same direction. In this case, the response variable will increase as the explanatory variable increases.
Answer:
Step-by-step explanation:
72 + 4t > 400
X could = 83 (since 82 will give you 400) or higher
A. Some lines have no slope. TRUE. Vertical lines have no defined slope.
B. The slope of a line is always positive.
FALSE. Slopes can be negative, zero or positive.
C. The slope of a line that moves up from left to right is positive.
TRUE. Example: y = 2x + 5 has a graph that moves UP as x increases.
D. If two lines have the same slope, then they are the same line.
FALSE. While this is possible, it does not consider the important case where two lines have the same slope but different vertical intercepts.
E. A steep line has negative slope. FALSE. Negative slope has little or nothing to do with the "steepness" of the line.
