The table shows the shipping costs for items of different values. which best describes the strength of the model? a weak positive correlation a strong positive correlation a weak negative correlation a strong negative correlation

We can plot the given points on the xy plane to get the strength and direction of the 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 attched scatter plot notice that the slope is positive because as x is increasing then y is also increasing.

We can draw a best fit line on this plot .

So, the model show a a strong positive correlation.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
