Answer:
Let z=−4+0i. Then, ∣z∣=
(−4)
2
+0
=4
Clearly, the point (−4,0) representing z=−4+0i lies on the negative side of real axis. Therefore, principal argument of z is π.
Answer:
a) 4,096
b) 0.000244
Step-by-step explanation:
a)
By the Fundamental rule of counting, there are
4*4*4*4*4*4 = 4,096
ways of forming six-digit arrangements where each position has 4 possibilities (1 to 4)
b)
The probability of entering the correct code on the first try, assuming that the owner does not remember the code is
1/4096 = 0.000244
475 - 95 = 380 = 20% of sales
20% = 1/5
380 × 5 = $1900 (the answer)
Hope this helps!
