<u>Answer:</u>
The correct answer option is 0.2.
<u>Step-by-step explanation:</u>
We are given that there are 3 red marbles and 3 green marbles in an opaque bag.
If two marbles are chosen one after one without replacement, we are to find the probability of getting both green marbles.
P (1st green marble) = 
P (2nd green marble) = 
P (both green marbles) =
= 0.2
X: -4, -2
Y: 2, 3
When you plug -4 and 2 it looks somewhat like this, 4(2)-2(-4)= 8+8+16. Then -2 and 3 would look something like this, 4(3)-2(-2)= 12+4=16.
Answer:
33 degrees
Step-by-step explanation:
(4x+1) and (2x-19) add up to 180 degrees

Answer:
307cm²
Step-by-step explanation:
This is a composite firgue so we need to split the two shapes, then find the area of both.
find the area of the rectangle
A=b*h
A=18*10
A=180
then find the area of the semicircle
A=1/2Pi*r²
A=1/2Pi*81
A=127.75 (We need to find the radius of the semicircle then square it)
then add the two areas 180+127.75=307.75
find the closet unit its
307cm²
7.8456 x 10^(-4)
this means you move the decimal place to the left 4 places to get the actual value
