Step-by-step explanation:

The line of best fit is y = 2.599x + 105.08.  At x = 20, the estimated height is y = 157.06.  The actual height is 160 cm, so the residual is:

160 cm − 157.06 cm = 2.94 cm

A new computer has a model number, a part number, and a serial number. The model number is assigned by the manufacturer to ident
kumpel [21]
<span>(serial number, model number)

That's a function mapping each serial number to its model number.

 (part number, serial number)

That's not a function; the same part number is in computers with different serial numbers

</span><span> (model number, part number)
</span><span>
That one's a bit confusing.  Normally a given model would have more than one part number inside so this isn't a function.  But here the description says there's only one part number for each model, so that would be a function.

(model number, serial number)

Not a function, more than one serial number for a given model number.
