Answer:

5/6

Step-by-step explanation:

A ruler has numbers as 1 ,2...12

When we consider numbers between 2 and 12, we can take numbers as

3,4,...11

i.e. there are 9 numbers between 2 and 12 (end values not exclusive)

Sample space has 12 numbers

Hence total probability is for the space between 0 and 12.

Space between 2 and 12 will be 10/12

=5/6

In the figure. d=4 yd, h=6 yd, and H=8 yd. What is the approximate volume of the figure? Use 3.14 to approximate
Nesterboy [21]
Check the picture below.

so is really just a cylinder with a cone on the side, notice, since the diameter of the base is 4, the radius is half that then.

so we just simply get the volume of the cylinder, and the cone, and sum them up

\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=2\\
h=6
\end{cases}\implies V=\pi \cdot 2^2\cdot 6\\\\
-------------------------------\\\\
\textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=2\\
h=2
\end{cases}\implies V=\cfrac{\pi \cdot 2^2\cdot 2}{3}\\\\
-------------------------------\\\\
\stackrel{cylinder's~volume}{24\pi }~~+~~\stackrel{cone's~volume}{\cfrac{8\pi }{3}}

Answer:

1). 25% percentage increase

2). 75% percentage decrease

Step-by-step explanation:

1.

Percent \: of \: change =  \frac{amount \: of \: change}{original \: amount}  \times 100\%

Amount of change =30-24=6

Original amount = 24

Percent \: of \: change =  \frac{6}{24} \times 100\%

Percent \: of \: change =  \frac{1}{4} \times 100\% = 25\%

This means there is a percentage increase of 25%

2.

Amount of change =4-16=-12

Original amount=16

Percent \: of \: change =  \frac{ - 12}{16} \times 100\%

Percent \: of \: change = -   \frac{3}{4} \times 100\% =  - 75\%

This means there is a percentage decrease of 75%
