Answer:
131/156 or about 84%
5/14 or about 36%
Step-by-step explanation:
P(<6 classes) = number of males and females not taking 6 out of total males and females, which is 131/156 or about 84%
P(M,5) = 74/156 x 20/74 which reduces to 5/14
That's the last one because you can factor to get
(x + 8)^2 = 36
(x + 8) = +/- 6
Answer:
- 14 + 18i
Step-by-step explanation:
Note that i² = ( )² = - 1
Given
4i(- i + 3) - 3(6 - 21) ← distribute both parenthesis
= - 4i² + 12i - 18 + 6i
= - 4(- 1) - 18 + 18i
= 4 - 18 + 18i
= - 14 + 18i
