Answer:
Step-by-step explanation:
let the national average be x
11/100 * x = 11x/100
25.47 - x = 11x/100
100(25.47-x) = 11x
2547 - 100x = 11x
2547 = 11x + 100x
2547 = 111x
x = 2547/111
x = 22.945945945946
22.95

How many diagonals are there in an convex n-gon?
n-3 diagonals.
The number of diagonals in a polygon = n(n-3)/2, where n is the number of polygon sides. For a convex n-sided polygon, there are n vertices, and from each vertex you can draw n-3 diagonals, so the total number of diagonals that can be drawn is n(n-3).

Answer:
The estimate is reasonable.
Step-by-step explanation:
Jamie's estimate seems reasonable.
We can see that there is (-24/27) in the bracket, first of all there is negative sign so there will be negative sign in the answer. Moreover, 24 is near to half of 27 so fraction will result in -0.5XXXXX and multiplying it with 1.4 will increase it around -0.75.
We can solve the given fraction for confirmation,
So,
which is near to -0.75 so the estimate of Jamie was right ..
