4+3 = 7
This is the amount of dollars spent each day
25/7 = 3 4/7
This means the money will last for 3 days.
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>
1/2 x 9/8 = 9/16
So the length is 9/8
The formula for perimeter (total length all around sides) for a rectangle is
P(L,w) = 2(L+w)
Assuming the neighbour wants to fence all around each yard, the total fence length is the total of two perimeters, namely
Length of fence
= 2(65+45) + 2(35+45)
=2(110)+2(80)
=220+160
=380 feet.
