Based on this scatter plot, whatcan you say about the relationship between study time and test scores?

Based on this scatter plot, I can say that in general, test scores vary directly with study time.  In other words, in a population large enough to reveal the direct relationship, the more time a student spends studying, the higher that student's test scores will be.

I didn't need a scatter plot to reveal that to me.  That's practically in the category of Law given to Moses at Sinai.

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
