Answer:
First, you need to know the general volume formula of a prism

We can think of the bottom as a triangle facing us, the height is 12.5ft
Use the formula to get
V=Sh=(4×6×1/2)×12.5=150 (

Answer: If you do some research you'll see color change is part of a chemical change, while a phase change is part of a physical change. For example: ice changing into water, or water changing into gas.
Answer:
a) (0.576, 0.624)
Step-by-step explanation:
Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%
α = 1 - C = 1 - 0.85 = 0.15
α/2 = 0.075
The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence 
The margin of error (E) is:

The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)
