Answer:
16
Step-by-step explanation:
6(3)-2
16
In order for the inverse to exist, the matrix cannot be singular, so we need to first examine the conditions for existence of the inverse.
Compute the determinant. The easiest way might be a cofactor expansion along either the first row or third column; I'll do the first.
The matrix is then singular whenever
.
With this in mind, compute the inverse.
If you join the arrays so that they fit as a rectangle, you get 5x6.
This is a little long for one question. I can see that 2 is CPCTE, and 1 is probably Given. 3 might be interior angles are equal.
Answer:
0.51
Step-by-step explanation:
Mathematically, for two individual events;
P(AnB) = P(A) * P(B)
P(A n B) = 0.6 * 0.85 = 0.51
