08.04a)the scatter plot below shows the test scores of a group of students who played

1)

Test score will decrease because the graph shows negative association.

2)

Graph A

Step-by-step explanation:

1)

Clearly from the graph we could observe from the scatter plot that:

Test score will decrease because the graph shows negative association.

( As the points or the test scores are decreasing with the increasing number of hours spent on playing games online)

2)

Positive Nonlinear association:

A positive Non-linear relationship between two variables can be shown with an upward-sloping curve in a graph.

Hence, Graph A represents the following relationship.

( Since graph B and D are linear and graph C is negative association since the value keeps on decreasing)

The second term in the sequence is -9

Step-by-step explanation:

Given the nth term of a sequence to be a(n) = a(n-1)+4 where n is the number of terms of the sequence

If a(1) = -13... (1)

The second term of the sequence is generated for n= 2:

a(2) = a(2-1)+4

a(2) = a(1)+4... (2)

Substituting equation 1 into 2

a(2) = -13+4

a(2) = -9

The second term in the sequence is -8
