Answer:
The answer choice is B
Step-by-step explanation:
In order for a function to work, the input value must go with only one output value, so the only one that work is b
Answer:
D
Step-by-step explanation:
1+2+2+3+3+3+4+5+6+6+7+7+7+8+9=73
73/15≈5
Answer:
y=5x+7
Step-by-step explanation:
parallel lines have the same slope, but different y intercepts
y=5x+7
Answer:
unit rate:2 y-intercept:6
Step-by-step explanation:
By using a scatter plot we can get the relationship of two variables or correlation.
There will be two types of correlation.
If the data of the plot show a positive slope of the estimated line then it will be a positive correlation.
Now a correlation value lie between 0 to 1 if it is very close to 0 like 0.1 , 0.2 then we can say the correlation is weak psitively correlated. and if it will be close to 1 like 0.8 or 0.9 then the correlation will be strong.
Similarly if slope of the estimated line will be negative then it will be a negative correlation.
From the above scatter plot notice that it has a negative slope and we can draw a fair estimate line on this scatter plot. So, there is strong negative correlation.
Hence the correct choice is -0.8.
