Answer:
Step-by-step explanation:
The different isotopes have different "half-lives" – the time it takes to lose half of its radioactivity. Pu-239 has a half-life of 24,100 years and Pu-241's half-life is 14.4 years. Substances with shorter half-lives decay more quickly than those with longer half-lives, so they emit more energetic radioactivity.
Since P(<em>X</em> = <em>x</em>) = 0.3 for all 0 ≤ <em>x</em> ≤ <em>α</em>, we have

So,


Answer:
67 ½ units³ or 135/2 units³
Step-by-step explanation:
Volume = Base area × height
In case:
width is 6 the height is 4 1/2 and the length is 2 1/2
2 ½ = 5/2
4 ½ = 9/2
Volume = (6 × 5/2) × 9/2
= 15 × 9/2
= 135/2
= 67 ½ units³
