<u>Answer:</u>
P(3 blue) = 1/5
<u>Steps:</u>
P(3 blue) = 2/3 × 3/5 × 1/2
P(3 blue) = 6/30
P(3 blue) = 1/5
<em>that's 20%</em>
Answer:
A.
Step-by-step explanation:
Physical scientists are often known as astronomers. Which is the study of space including planets, moons, comets etc.
The unit normal for the given plane is <5,2,-1>.
The equation of the plane parallel to the given plane passing through (5,5,4) is therefore
5(x-5)+2(y-5)-1(z-4)=0
simplify =>
5x+2y-z=25+10-4=31
Answer: the plane through (5,5,4) parallel to 5x+2y-z=-6 is 5x+2y-z=31
