2. Range = Maximum value in two conferences - Minimum value in two conference
= 12 - 0
=12
The mean number of wins for teams from the two conferences is 7.65.
The range in wins is 12.
The probability of the uppermost faces is 34
Answer:
8-3i
Step-by-step explanation:
The complex additive inverse is the number we need to add so that we get zero. It is the negative of the number.
a + bi is –(a + bi) = –a – bi.
a+bi + (-a+-bi) = a-a + bi-bi = 0
The complex additive invers of -8+3i is
-(-8+3i)
Distribute the negative
8 -3i
