Can you retake that picture I couldn't see it all.
A. <span>the probability of a false negative test results
This corresponds to
P (false | negative) = P (false) x P (negative)
= (1 - P(true)) (1 - P(positive))
= (1 - 0.75)(1 - 0.88)
= 0.03
b. </span><span>he probability of a false positive test result
= (1 - 0.75) (0.88)
= 0.22</span><span />

Answer: Nigeria and Liberia
Explanation:
A compact state is one where the distance from the center of the country is more or less the same to all the boundaries of the country.
Nigeria is a compact state with the center being in the capital of Abuja. Its compact nature allows for roads to be built easier. Liberia to the west of Africa is also a compact state with its shape being decided by European powers when they were scrambling for Africa in the Berlin Conference.
Scientists can determine the age of the seafloor by watching the constant changing magnetic field of our planet. When it cools down, it records the magnetic field during its formation. The two parts of the oceanic plate are pulled apart, and magnetic stripes become older as they move away from the mid-ocean ridge. Hope that helps!
