Apoint is chosen at random in a large square what percent of the time will the point be in the shaded region

  84.5%

Step-by-step explanation:

The area of the smaller square is ...

  smaller square = (5.98 cm)^2 = 35.7604 cm^2

The area of the larger square is ...

  larger square = (15.2 cm)^2 = 231.04 cm^2

So, the shaded area is ...

  larger square - smaller square = (231.04 -35.7604) cm^2 = 195.2796 cm^2

Then a randomly chosen point will be in the shaded region this fraction of the time:

  (shaded area)/(larger square area) = 195.2796/231.04 ≈ 0.84522 ≈ 84.5%

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
