Question

write the mean proportion of 4 and 25​

Answer 1

SOLUTION :

Mean is the Average.

Mean = Total sum / No of numbers

Mean = 4 + 25 / 2

Mean = 29 / 2

Mean = 14.5

Answer 2

let the mean proportion of 4 and 25 be x
then 4,x and 25 are in continued proportion
therefore
$\frac{4}{x} = \frac{x}{25} \\ 4(25) = x(x) \\ 100 = {x}^{2} \\ x = \sqrt{100} \\ x = 10$
