Answer:
Of course they were incorrect
Step-by-step explanation:
Anything to the power of 0 will always be 1, no matter what the number is.
Answer:
- <u>Surface Area = 399.4 m²</u>
- <u>Volume = 1675.5 m³</u>
Step-by-step explanation:
<u>Lateral Surface Area of the Cylindrical Part</u>
- 2πrh
- 2 x π x 5 x 8
- 80 x π
- 251.3 m²
<u>Slant height of cone</u>
- √r² + h²
- √25 + 64
- √89
- 9.43 m
<u>Surface Area of Conical Portion</u>
- πrl
- π x 5 x 9.43
- 47.15 x π
- 148.1 m²
<u>Total Surface Area</u> :
- 251.3 + 148.1
- <u>399.4 m²</u>
<u></u>
<u>Volume</u>
- V = πr²h + 1/3πr²h
- V = πr²h (1 + 1/3)
- V = π x 25 x 8 x (4/3)
- V = π x 1600/3
- V = <u>1675.5 m³</u>
The Minimum sample size table is attached below
Answer:
![X=173](https://tex.z-dn.net/?f=X%3D173)
Step-by-step explanation:
From the question we are told that:
Confidence Interval ![CI=99\%](https://tex.z-dn.net/?f=CI%3D99%5C%25)
Variance ![\sigma^2=30\%](https://tex.z-dn.net/?f=%5Csigma%5E2%3D30%5C%25)
Generally going through the table the
Minimum sample size is
![X=173](https://tex.z-dn.net/?f=X%3D173)
Answer:
250
Step-by-step explanation:
If 15 is 6% multiplying it by 16.66666666666667 will make it 100%
15 x 16.66666666666667 = 250
Another way to do this is divide by 6 and multiply by 100
Answer: A. Less than 0
Step-by-step explanation:
The answer when solving it gives you
x = -1.46557113 which means it is less than 0
