The possible distance between the parallel chords whose lengths are 6 cm and 16 cm is 15.5 cm

<h3>How to determine the length between the two chords?</h3>

The diameter of the circle is given as:

D = 20cm


Calculate the radius (r)

r = 10 cm

For the chord of length 6 cm;

The distance of chord from the center of the circle is:

d = \sqrt{10^2 - (6/2)^2}

Evaluate

d = 9.5

For the chord of length 16 cm;

The distance of chord from the center of the circle is:

D = \sqrt{10^2 - (16/2)^2}

Evaluate

D = 6

The sum of both distances is the possible distance between both chords.

Distance = 9.5 + 6

Distance = 15.5

Hence, the possible distances between the chord is 15.5 cm

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.
