Let the number of shaded square be x. And it is given that total number of squares are 25.

Substituting the values

Performing cross multiplication

So 5 squares should be shaded to create a region with a geometric probability of 0.2 .
Answer:
NOT proportional
Step-by-step explanation:
y/x = 5/2 = 2.5
y/x = 6/3 = 2
also 7/4 = 1. 75 and 8/5 = 1.6 so:-
They are NOT proportional
Answer:
-2[h(3)] = 0
Step-by-step explanation:
Step 1: Define
h(x) = 2x - 6
Step 2: Find h(3)
h(3) = 2(3) - 6
h(3) = 6 - 6
h(3) = 0
Step 3: Find -2[h(3)]
-2(0)
0
