There are two main ways of doing this, depending on your level of understanding,and of what you have been taught in class.

<u>First Option

</u>
<u><em /></u>First you could make up lengths that result in a volume of 24dm³, and then halve those lengths and work out the new volume:
<u>
</u>
<u></u><em>For example:
</em>
<em><u /></em><u>Lets say that:</u>

The height = 4
The width = 3
The length = 2

We know that these result in a volume of 24dm³ (<em>because 4 x 3 x 2 = 24)

</em>Now lets see what happens to the volume when we halve these units
<em>
</em>The new height = 2                <em>(because 4 </em>÷ 2 = 2)
<em />The new width = 1.5               <em>(because 3 </em>÷ 2 = 1.5)
The length = 1                         <em>(because 2 </em>÷ 2 = 1)

Now lets work out the new volume:
 2 x 1.5 x 1 = 3dm³
-------------------------------------------------------------------------------------------------------------

Answer:
So the new volume will be 3dm³



-------------------------------------------------------------------------------------------------------------

<u>Second Option
</u>

If you have done the relationship between scale factors of lengths, areas and volumes, then you can work it out another way.

We know the <u>Length Scale Factor</u> is 0.5    ( 1/2)
To get the <u>Volume Scale Factor,</u> we cube ( ³ ) the length scale factor) :

So the Volume Scale Factor is;
     0.5³ = 0.125.

Now that we have the Volume Scale factor, we multiply it by the old volume to get the new volume:

24 x 0.125 = 3dm³

<em>(P.S  if you haven't learnt about this  in class yet, then don't worry about it)</em>

Suppose that the breaking strength of a rope (in pounds) is normally distributed, with a mean of 100 pounds and a standard devia
EleoNora [17]

Answer:

0.961

Step-by-step explanation:

To answer this, find the area under the standard normal curve to the left of 130 pounds:

Using the function normalcdf( on a TI calculator, we get:

normalcdf(-1000, 130, 100, 17) = 0.961
