Answer: True. f is a function.

Step-by-step explanation:

We know that function is a relation from a set of inputs to a set of possible outputs where each input is associated to exactly one output.

It means a relation for which each value from the set the first coordinate of the ordered pairs is related with exactly one value from the set of second coordinate of the ordered pair.

For the given set f= {(2, 5), (3, 2) (4, 6), (5, 1), (7, 2)}, here each input is associated to exactly one output.

Therefore, it is a function.

The heights (in cm) and arm spans (in cm) of 31 students were measured. The association between (height) and (arm span) is shown
sergeinik [125]

Answer: Mike's arm span is 7.165 cm longer than the George's one.

Step-by-step explanation:

We have that the association between height and arm span is modeled by the equation

y = 4.5 + 0.977*x

where y is height and x is arm span.

Mike is 172 cm tall, so his arm span is:

172cm = 4.5 + 0.977*x

x = (172 - 4.5)/0.977 = 171.443 cm

and George is 165 cm tall, so his arm span is:

x = (165 - 4.5)/0.977 = 164.278 cm

Then the difference between their arm span is:

171.443cm - 164.278cm = 7.165 cm

So Mike's arm span is 7.165 cm longer than the George's one.
