25. yes it's direct variation
26. yes
The angle the radius makes with AB is a right angle, so the Pythagorean theorem applies.
r² = 17.4² - 7² = 253.76
r = √253.76 ≈ 15.9
The length of radius r is about 15.9.
Well you can use the Pythagorean Theorem Formula a
+b
=c
. Just plug in the first 2 least numbers into a and b, and see if your answer(c) is equal to the last number. Hope I helped!

The measure of central tendency that David's mum can use to argue is the mean.
<h3>What is the Mean of a Data?</h3>
The mean of a data is the average of the data points in the data distribution. The mean is a measure of central tendency.
If David really spent enough time on homework, the average of the time he uses will give David's mum the mean time spent by David, which she can use for her argument.
Thus, David's mum can use the mean as a measure of central tendency.
