Answer:

Height of the cone is thrice the height of the cylinder

Step-by-step explanation:

Let 'h' b e the height of the cylinder and 'H' be the height of the cone.

Volume of cylinder = base area × h

Volume of cone = 1/3 (base area)×H

Since the volumes are equal with same base areas,

base area × h = 1/3 (base area)×H

h = H/3

Or,

3h = H

Answer: it is =4176000000000000

Step-by-step explanation:

(2.9)(100000)(7.2)(10^2)

5(10^−8)

(290000)(7.2)(10^2)

5(10^−8)

2088000(10^2)

5(10^−8)

(2088000)(100)

5(10^−8)

208800000

5(10^−8)

208800000

5(1/100000000)=

208800000/1

20000000

=4176000000000000

Answer:

Follows are the solution to this question:

Step-by-step explanation:

$95 \% \$ the confidence level for z:

$\alpha = 1 - 95 \% \\\\$

$= 1 - 0.95 \\\\ = 0.05$

$\to \frac{\alpha}{2} = \frac{0.05}{2} = 0.025\\\\\\to Z \ \frac{\alpha}{2} = Z_{0.025} = 1.96$

Calculating the Margin of error:

$E = Z\ \frac{\alpha}{2} \times ( \frac{\sigma}{\sqrt{n}})$

$= 1.96 \times ( \frac{5000}{\sqrt{\sqrt{100}}})\\\\= 980$

The population means estimate a 95 % confidence interval is:

$\to \bar{x} \frac{+}{-} E\\\\ = \$ 90000 \frac{+}{-} 980$
