All sides of a square re equal and opposite sides are parallel to each other.
Assuming that E is the point where the diagonals intersect (since we are not told in the question), then <span>AEB ≅ DEC.
By SAS,
2 sides are equal. That is AE = EC and DE = EB.
The triangles share a common angle. That is <DEC=<AEB
The property used t</span><span>he diagonals bisect each other.</span>
The eqution of height y in terms of the time x is
We are asked when the rocket will strike the ground, so that is the same that sayin when will the rocket's height will be zero again, that is, y=0. so we have to solve
the solutions of this equations are
So, the rocket will strike the ground after 7.3 seconds
Answer:
I would say option C.
A and B are not independent events because P(A|B)≠P(A) .
Step-by-step explanation:
We know that: P(A|B) = P(AandB)/P(B)
now, we can plug values that were given.
P(A|B) = 0.15/0.9
P(A|B) = 0.16666
but we have P(A)=0.5
We can see that both are not equal.
P(A|B) ≠ P(A)
So, A and B are not independent.
The answer should be B. 8x-10
