The volume can be determine by subtracting volume of smaller cuboid from the volume of the bigger cuboid.
Thus, by removing smaller cuboid from the bigger, we can determine the volume of the resultant figure.
Thus, Option (b) is correct.

Step-by-step explanation:

x-3=14

x=14+3

x=17

verification

x(17)-3=14

17-3=14

14=14

Answer:

Step-by-step explanation:

Group 1 Information:

sample size : n₁ = 200

individuals with stomach as a side effect x₁ = 45

p₁ = 45 / 200 p₁ = 0,225 then q₁ = 1 - p₁ q₁ = 0,775

Group 2 Information:

sample size : n₂ = 150

individuals with stomach as a side effect x₂ = 33

p₂ = 33/150 p₂ = 0,22 q₂ = 0,78

Hypothesis Test:

Null Hypothesis: H₀ p₁ = p₂

Alternative Hypothesis Hₐ p₁ > p₂

The alternative hypothesis indicates that the test is a one-tail test to the right

Significance level is α = 0,01 ( confidence interval 99%)

From z-table we get z(c) for that α z(c) = 2,32

To calculate z(s)

z(s) = ( p₁ - p₂ ) / EED

EED = √ ( p₁*q₁)/n₁ + ( p₂*q₂)/n₂

EED = √ ( 0,225*0,775)/200 + (0,22*0,78)/150

EED = √ 0,0008718 + 0,001144

EED = 0,045

z(s) = ( 0,225 - 0,22 ) / 0,045

z(s) = 0,005 / 0,045

z(s) = 0,11

Comparing z(s) and z(c)

z(s) < z(c) 0.11 < 2.32

Then z(s) is in the acceptance region. We accept H₀ . We don´t have evidence to support differences between the two groups.

What is x, if the volume of the cylinder is 768pi rcm3?

AVprozaik [17]

let's recall Cavalieri's Principle, <u>solids with equal altitudes and cross-sectional areas at each height have the same volume</u>, so even though this cylinder is slanted with a height = x and a radius = 8, the cross-sectional areas from the bottom to top are the same thickness and thus the same area, so its volume will be the same as a cylinder with the same height and radius that is not slanted.

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=8\\ h=x\\ V=768\pi \end{cases}\implies 768\pi =\pi (8)^2(x)\implies 768\pi =64\pi x \\\\\\ \cfrac{768\pi }{64\pi }=x\implies 12=x$
