A cylindrical container 30cm in diameter holds approximately 30 litres of oil. how far does the oil level fall after 1 litre of

LenaWriter [7]

The fall in the level of oil is <u>1.4147 cm</u> when the total volume of oil consumed is 1 liter.

We assume the drop in the level of water to be d cm.

Since the container is cylindrical in shape, its volume is given as:

V = πr²h, where V is the volume, r is the radius, and h is the height.

In the question, we are given that the diameter of the can is 30 cm.

Hence its radius = 30/2 = 15 cm.

The capacity of the container is given to be 30 liters or 30*1000 = 30000 cm³.

The volume of the oil used = 1 liter or 1*1000 = 1000 cm³.

Thus, substituting V = 1000, r = 15, and h = d, in the formula of the volume, V = πr²h, we get:

1000 = π(15)²(d),

or, d = 1000/(225π) = 1.4147.

Thus, the fall in the water level is 1.4147 cm.

Therefore, the fall in the level of oil is <u>1.4147 cm</u> when the total volume of oil consumed is 1 liter.

Mr. Starnes wondered what proportion of Katy Perry's Twitter followers are

Citrus2011 [14]

Answer and Step-by-step explanation:

To calculate a confidence interval for a proportion:

1) Determine the proportion

$p=\frac{308}{500}$

p = 0.616

2) A 90% confidence interval has z-score that is 1.645.

3) Calculate margin of error

$ME=\sqrt{\frac{p(1-p)}{n} }$

where

n is the sample size

$ME=\sqrt{\frac{0.616(1-0.616)}{500} }$

$ME=\sqrt{\frac{0.616(0.384)}{500} }$

ME = 0.02175

Then the interval is given by

p ± z(ME)

0.62 ± 1.645(0.02175)

0.62 ± 0.035

The interval will be

0.585 < p < 0.655

What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.
