Answer:
<h2>The answer is option C</h2>
Step-by-step explanation:
<h3>
</h3>
Using the rules of indices
Since the bases are the same and are dividing we subtract the exponents
That's
<h3>
</h3>
So we have
<h3>
</h3>
Using the rules of indices
<h3>
</h3>
So we have the final answer as
<h2>
</h2>
Hope this helps you
Variance of a continuous random variable X is defined as
Standard deviation is defined as
Hence standard deviation is the positive square root of variance.
The basic ratio of 25:40 would be 5:8.
Since 25:40 is equivalent to the fraction 25/40, you would simplify.
25 (divided by) 5 = 5
40 (divided by) 5 = 8
So, the answer is 5:8.
