<span>Standard Form of an Equation of an Hyperbola opening up and down is:
(y-k)^2 / b^2 - (x-h)^2 / a^2 = 1
</span><span>where Pt(h,k) is a center with vertices 'b' units up and down from center.
</span><span>vertices: vertices: (0,+-2) b = 2 AND Center is (0,-0)
(y)^2/4-(x)^2/a^2=1
</span><span>foci: (0,+-7)
a^2 = 24
square root of 4 + a^2 = 5.29
4 + 5.29 = 9.29
y^2 / 4 - x^2 / 24 = 1</span>
Answer:
(-2,-6)
Step-by-step explanation:
Answer:
The first box is 0.42 Second box is 42%
Step-by-step explanation:
The length of x would be 2 units. You already know that 40 degrees equals eight cm. With that you can break the equation into parts.
If 40 degrees equals eight, then 20 degrees would equal four units. Using that hypothesis, you can then infer that x=2 units.
Hope that helped.

Answer:</h2>
The probability that a defective component came from shipment II is:
<h2>
Step-by-step explanation:</h2>
Let A denote the event that the defective component was from shipment I
Also, P(A)=2%=0.02
and B denote the event that the defective component was from shipment II.
i.e. P(B)=5%=0.05
Also, P(shipment I is chosen)=1/2=0.5
and P(shipment II is chosen)=1/2=0.5
The probability that a defective component came from shipment II is calculated by Baye's rule as follows:
Hence, the answer is:
