In-s [12.5K]

Based on the calculations, the volume of this louvre pyramid is equal to 8,983 cubic meter..

<u>Given the following data:</u>

Base width = 35 meters.

Height = 22 meters.

<h3>How to calculate the volume of a pyramid?</h3>

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × base area × height

For the base area, we have:

Area = w²

Area = 35² = 1,225 m².

Substituting the parameters into the formula, we have;

Volume = 1/3 × 1,225 × 22

Volume = 1/3 × 26,950

Volume = 8,983 cubic meter.

The contents of seven similar containers of sulfuric acid are 9.8, 10.2, 10.4, 9.8, 10.0, 10.2, and 9.6 liters. find a 95% confi
Kamila [148]
The confidence interval is from 9.81 to 10.19.

We first find the mean of the data:

<span>(9.8+10.2+10.4+9.8+10.0+10.2+9.6)/7 = 10

Next we find the standard deviation:
</span>σ=√([<span>(9.8-10)^2+(10.2-10)^2+(10.4-10)^2+(9.8-10)^2+(10-10)^2+(10.2-10)^2+(9.6-10)^2]/7) = 0.262

The z-score for 95% confidence is found by
1-0.95 = 0.05; 0.05/2 = 0.025; from the z-table, it is 1.96.

The confidence interval is calculated using
</span>x\pm z\times (\frac{s}{\sqrt{n}})&#10;\\&#10;\\10 \pm 1.96(\frac{0.262}{\sqrt{7}})=10\pm 0.1941<span>
