Answer:
0.933 ; not independent
Step-by-step explanation:
Given :
A - made from natural polished wood
B - made from chrome accent
P(A) = 0.9
P(B) = 0.75
P(AnB) = 0.7
1.) probability of natural wood Giveb that it has chrome accent
P(A|B) = P(AnB) / P(B)
P(A|B) = 0.7 / 0.75
P(A|B) = 0.933
2.)
For an independent event :
P(AnB) = p(A) * p(B)
P(AnB) = 0.9 * 0.75 = 0.675
However, p(AnB) Given here is 0.7, thus the event aren't independent

</span><span>☛ We know that (-1,-3) is the vertex.
</span>☛ Set up the parabola as y = k(x+1)²-3
☛ 1 = k(0+1)²-3
☛ k = 4
☛ y = 4(x+1)²-3 is the equation

All acute angles are 30 degrees.
4x (2x-3) (x+2) would be your answer.
