1 answer:

6 0

What does trail mean, I am assuming it means the last try.
5/6^3*1/6) this shows that there is a 5/6 chance of not getting a 4 on the first 3 tries and and a 1/6 chance of getting a 4 on the last one.
125/1296. That is what I think I might be wrong.

A container built for transatlantic shipping is constructed in the shape of a right rectangular prism. Its dimensions are 7 ft b

____ [38]

Given:

Dimensions are 7 ft by 5 ft by 8.5 ft

Contents weigh 0.21 pound

Contents worth $8.80 per pound

Find-: value of container contents.

Sol:

Volume is:

$\begin{gathered} Volume\text{ = }7\times5\times8.5 \\ \\ =297.5 \end{gathered}$

The formula of density is:

$\text{ Density =}\frac{\text{ Mass}}{\text{ Volume}}$

So,

$\begin{gathered} 0.21=\frac{\text{ Weight of contents in container}}{\text{ Volume of container}} \\ \\ 0.21=\frac{\text{ Weight}}{297.5} \\ \\ 0.21\times297.5=\text{ Weight} \\ \\ \text{ Weight of contents in container = }62.475\text{ Pound} \end{gathered}$

Now $8.80 per pound

For 62.475 pounds the value is:

$\begin{gathered} =62.475\times8.80 \\ \\ =549.78 \end{gathered}$

So the value of the container contents is 549.78
