Is it mathematically correct to say that:
Step2247 [10]

Answer: Yes

Step-by-step explanation:

    Since the numerator is multiplying square root 13 by square root 2, we can break them apart.

\displaystyle \frac{\sqrt{13*2}}{\sqrt{13}} =\frac{\sqrt{13}*\sqrt{2}  }{\sqrt{13}}

   You are correct, \sqrt{13} over  \sqrt{13} is equal to one, so we can "cancel them out" of our expression.

\displaystyle \frac{\sqrt{13} }{\sqrt{13}} = 1

   This leaves us with: \sqrt{2}<em />

<em />

<em>We can also test this by using a calculator:</em>

<em />\frac{\sqrt{13*2}}{\sqrt{13}} \approx 1.41421356\\\sqrt{2} \approx 1.41421356\\1.41421356=1.41421356

What is the probability that a t random variable with 7 degrees of freedom is greater than 1.895? round your answer to two decim
geniusboy [140]

The probability that a t random variable with 7 degrees of freedom is greater than 1.895 is 0.05

<h3>How to solve for the probability</h3>

We have to solve this by using the t distribution table that has the degree of freedom as 7.

Under this table we have to search for the value 1.895 and the probability value that it falls under.

Hence we would have 1.895 (1-0.95) = 0.05

Hence we have to conclude that the  the probability that a random variable with 7 degrees of freedom is greater than 1.895 is 0.05
