Answer:
4v-6.3w+9.8
Step-by-step explanation:
If you distribute the negative sign (same as distributing -1), then you get -(-4v) + (-6.3w) - (-(9.8))
Basically it's switching the signs
Hope that helped :)
Answer:
The answer is "It would decrease, but not necessarily by 8%".
Step-by-step explanation:
They know that width of the confidence level is proportional to a confidence level.

Answer:
x = 80 degrees
Step-by-step explanation:

y degrees = 80 degrees
x = y (Vertically opposite angles are equal)
So,
x = 80 degrees
