Answer:   (5n - 8)(n² - 3)

<u>Step-by-step explanation:</u>

You can factor this using the Grouping Method (hint: rearrange the terms)

   5n³ - 8n² - 15n + 24

=  5n³ - 15n   -8n² +24

=  5n<u>(n² - 3)</u>   -8<u>(n² - 3)</u>

= (5n - 8)(n² - 3)

A standard number cube is tossed. Find the following probability. ​P(greater than 4 or odd​)
lorasvet [3.4K]
A standard cube has 6 possible outcomes. But since we want to find P(4+ or odd), the outcomes become more narrow.
So:
6 outcomes -> 1, 2, 3, 4, 5, 6

But we want to find 4+
So:
4+ = 4, 5, 6

We also want to find all odd possibilities.
So:
odd = 1, 3, 5

As you can see, there is a 5 in both the 4+ and the odd numbers so 5 will only be counted once.
P(4+ or odd) = 1, 3, 4, 5, 6

So the probability of having an outcome that is P(4+ or odd) is:
5/6 or 0.8333 or 83.33%

Hope I helped!

Area of the bigger shape :6*9 =54cm squared

Area of the cut out shape:4*4=20cm squared

<h3>Area of the whole shape is 54 - 20 = 34cm squared</h3>
