Answer:
Since the slope of the line is (31/4 - 25/4) / (5/4 - 3/4) = 3 that means that for every 1 that x increases, y increases by 3 so an example could be 1 3/4 for x and 9 1/4 for y.
It si cool so basicly u take 5 divide bye 13 times 5
Answer:
C. Age is a probably lurking variable in this study.
Step-by-step explanation:
The two variables that are related in this study are arithmetic and exercise.
The variable which is not known and cannot be controlled is age. But it may effect other variables. Such a variable is called lurking variable.
In this experiment we know the age range but not exact age. It may effect as younger students may not be able to solve questions easily.
Choice C is the most appropriate conclusion given for the finding.
121kg/120 I think that’s the answer I’m not sure
2.)68
3.) 2.75
4.) to be proportional the line must start threw the origin and be linear. This graph starts threw the origin as is linear which means it is proportional
Sorry if it’s wrong. Hopefully I helped!!
