? Liter equivalent to 0,000 000 000 013 cubic kilometers
Amiraneli [1.4K]

<em><u>Question:</u></em>

? Liter equivalent to 0.000 000 000 013 cubic kilometers

How do we do it?´

<em><u>Answer:</u></em>

13 liter is equivalent to 0.000 000 000 013 cubic kilometers

<em><u>Solution:</u></em>

Given that,

? Liter equivalent to 0.000 000 000 013 cubic kilometers

So we have to convert cubic kilometer to liter

<em><u>Use the following conversion factor</u></em>

1\ km^3 = 1000000000000\ liter

Therefore,

0.000 000 000 013\ km^3 = 0.000 000 000 013 \times 1000000000000\ liter\\\\0.000 000 000 013\ km^3 = 13\ liter

Thus, 13 liter is equivalent to 0.000 000 000 013 cubic kilometers

Let x be normal distribution with mean 70 and standard deviation 2. given the following probability, p (x &lt; a) = 0.9147, find
lapo4ka [179]

The value of a is 72.74.

<h3>What is Probability ?</h3>

Probability is the study of likeliness of an event to happen.

It is given that

The mean \rm \mu of the distribution is 70

Standard deviation \rm \sigma  is 2

p( x<a) = 0.9147

a = ?

From Z table

For p ( p < 0.9147) , z = 1.37

\rm Z = \dfrac { X - \mu}{ \sigma}

\rm \rm 1.37 = \dfrac { a - 70}{ 2}

a = 70+ 2*1.37

a = 72.74

Therefore the value of a is 72.74.
