Answer: 8 mi3
Step-by-step explanation:
Area of triangle 1/2 * base * height
= 1/2 * 3 * 4
= 6 mi2
Volume of triangular pyramid = 1/3*area* height of pyramid
= 1/3 * 6 * 4
= 8 mi3
Answer:
The answer is 15.
Step-by-step explanation:
Don't forget about the A and H equaling 5. That is there to throw you off. A and B equals 8. Right? Well that's the length. The the A and E is 3. Right? Well that's the height. what you do is cut the triangular prism in half and you end up with a triangular prism with a height of 5. Then you multiply that with 1.5. You get 1.5 by dividing 3 by 2. You then get 7.5. Now multiply that with 2. Your final answer is 14.
1,000,000 i dont really know how to explain it. sorry
The minitab report isn't given.
Answer:
H0 : μ = 2 um
H1 : μ ≠ 2 um
Step-by-step explanation:
The mean surface roughness of coated interior pipe is given as 2um.
This refers to the population mean, μ = 2 um
Therefore, the null hypothesis which usually aligns with the population mean value will be stated as :
H0 : μ = 2 um
The alternative hypothesis is used to test the claim that the mean surface roughness is different from 2 ; hence no direction is given, this is thus a 2 - tailed test
H1 : μ ≠ 2 um
