Answer:
x = -7
Step-by-step explanation:
4(1 - x) + 2x = -3 (x + 1)
4 - 4x + 2x = - 3x - 3
- 4x + 2x + 3x = - 3 - 4
x = -7

Answer:
speed
Step-by-step explanation:
it's literally stated in the question
Standard deviation = √(n * p * q)
You are given n and p
q = 1 - p
q = 1 -0.2 = 0.8
Standard deviation = √(21 * 0.2 * 0.8)
=√3.36 = 1.83
The answer is A.
