Answer:
f[((5)] = g(5) = root of 5+7= root of 12
then f[( g(5)] = (root of 12 _ 3 )^2 = 12-9 =3
Total marbles: 1+ 4+3 = 8
Picking a blue marble = 4/8 = 1/2
Picking a second one: 1/2 x 1/2 = 1/4 probability
Answer:
156
Step-by-step explanation:
Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be (n-2) 13 × 180 = 2340 degrees. Since the 15-gon is regular, this total is shared equally among the 15 interior angles. Each interior angle must have a measure of 2340 ÷ 15 = 156 degrees.
Answer:
