What is the exact volume of the cone?

Mathematics
1 answer:
zlopas [31]3 years ago
4 0

Answer:

The third choice, (160/3)π cm³

Step-by-step explanation:

The formula for volume of a cone is

V = (1/3)πr²h   where r is the radius of the base, and h is the height

Here, r = 4 and h = 10. plug those values in and simplify...

V = (1/3)π(4²)(10)

V = (1/3)π(16)(10)

V = (1/3)π(160)

V = (160π)/3

Construct the 95% confidence interval for the population mean using the appropriate distributions. a. A random sample of 50 peop
SSSSS [86.1K]

Answer: 95% confidence interval would be (26.01,29.39).

Step-by-step explanation:

Since we have given that

n = 50

Mean = 27.7

Standard deviation = 6.12

We need to construct 95% confidence interval for the population.

so, z = 1.96

So, it becomes,

\bar{x}\pm z\times \dfrac{\sigma}{\sqrt{n}}\\\\=27.7\pm 1.96\times \dfrac{6.12}{\sqrt{50}}\\\\=27.7 \pm 1.69\\\\=(27.7-1.69,27.7+1.69)\\\\=(26.01,29.39)

Hence, 95% confidence interval would be (26.01,29.39).
