Answer:
0
Step-by-step explanation:
73x=0
Let's allow ?=x because we need an unknown number.
x=0/73=0
x=0
Answer: Choice B) negative linear association
=================================
Reasoning:
The points all go downhill as you move from left to right. We can draw a straight line that is fairly close to all of them. This is known as the regression line. The regression line having a negative slope tells us the linear association is negative. This means the correlation coefficient r is negative, so,
(r = -1 is not possible as not all points fall on the same straight line)
Answer:
A
Step-by-step explanation:
in order for it to be a function the x needs to have only one y, in this case the x is repeated for two different y's
Since 80% of the 300 total points is 240, and we have 127 so far, 240-127=113 as a minimum
