Answer:
a) The study suggests a negative correlation because the study shows that as time spent on social networking websites Increases, grade point average tends to decrease.
b) While it is possible that there is a cause and effect relationship, it is not necessarily the case.
Step-by-step explanation:
Since the study submitted that, students who rarely never used social networking websites had higher grade point averages than students who use social networking websites. It implies a negative relationship. Thus, the option given above is the correct answer.
Similarly, the study might imply some cause and effect relationship but it is not necessarily to be the case. <em>That is, low grade point could result into more time with social networking website. </em><em>This is not necessary to be TRUE!</em>

Answer:
60
Step-by-step explanation:
The exterior angles of the polygon are the supplement of the interior angles, so are ...
180° -174° = 6° . . . . measure of each exterior angle
The sum of exterior angles is 360°, so ...
n(6°) = 360°
n = 360°/6° = 60
The polygon has 60 sides.
The length of side of triangle is 5 units and length of side of pentagon is 1.5 units.
<u>SOLUTION:</u>
Given, An equilateral triangle has sides of length 
units.
Then, perimeter of the triangle will be 
A regular pentagon (5 sides) has sides of 
units.
Then, perimeter of the pentagon will be 
We have to find the dimensions of each shape
. Now, the perimeter of the triangle is twice the perimeter of the pentagon,
So, 
Then, length of side of triangle 
Length of side of pentagon 
We have to neglect, negative sign as lengths can’t be negative. Even if we change the sign above all conditions are satisfied.
