Answer:
P(-A) = 0.388
Step-by-step explanation:
By the <u> PROBABILITY POSTULATE: </u>
P(A) + P(not A) = 1
Here, P(A) = 0.612
So, P(not A) = P(-A) = 1 - 0.612 = 0.388
⇒P(-A) = 0.388
Answer:
a or the first one
Step-by-step explanation:
built:Different
Step-by-step explanation:
y = -3x² + mx + 10
dy/dx = -6x + m.
When dy/dx = 0, -6x + m = 0. => x = m/6.
We have y = -3(m/6)² + m(m/6) + 10 = 37.
=> -m²/12 + m²/6 = 27
=> -m² + 2m² = 324
=> m² = 324
=> m = 18 or m = -18.
