Answer:
Graph B
Step-by-step explanation:
we know that
The graph that represent the situation
As x increases, y increases
Is the graph B or the graph C
but
Graph B represent a moderate coefficient of correlation r (-0.5 to -0.3 or 0.3 to 0.5)
Graph C represent a strong coefficient of correlation r (-1.0 to -0.5 or 1.0 to 0.5)
In this problem we have r=0.42
so
The coefficient of correlation is Moderate
therefore
The answer is the Graph B
Answer:
(3,5)
Step-by-step explanation:
Answer:
c) -2/5=0.4 d) -5/2=0.4 are incorrect
Answer:
It would increase by 1
Step-by-step explanation:
Step 1: Find the mean of the original
(9+6+1+1+3)/5 = 4
Step 2: Find the mean of the new
(9+6+1+1+8)/5 = 5
Step 3: Find the difference
5 - 4 = 1
A) 19m because 3 times 6 is 18 then you add m, which would be 19m
