Answer: 1 1/3 or 4/3
Step-by-step explanation: f(4) =1/3(4) = 4/3 = 1 1/3
Answer:
102.2
Step-by-step explanation:
Answer:


And the slope would be:

Now we can find the means for x and y like this:


And we can find the intercept using this:

So the line would be given by:

And the best option is:
A. y = 0.894x + 0.535
Step-by-step explanation:
We have the following dataset given
x: 5,6,9,10,14
y: 4,6,9,11,12
We want to find the least-squares line appropriate for this data given by this general expresion:

Where m is the slope and b the intercept
For this case we need to calculate the slope with the following formula:

Where:


So we can find the sums like this:





With these we can find the sums:


And the slope would be:

Nowe we can find the means for x and y like this:


And we can find the intercept using this:

So the line would be given by:

And the best option is:
A. y = 0.894x + 0.535
