The mean of the data is 15 all you gotta do is add all the number up and divide by the numbers added
That's written as 5.6 x 10⁻¹⁷ .
(To change 5.6 into the original number, you'd need to
move the decimal point 17 places backwards.)
if,
p/x=x/q
then cross-multiplying gives <span>x^2=pq</span>
<span>x^2=pq</span>. Taking the square root of both sides, we get <span>x=√pq</span> as the geometric mean of p and q.
Hence in the given question the product of p and q is 8.
so,
x=√8
x=2√2
