Novosadov [1.4K]
Based on the given description above, I have analyzed it and come up with a solution to get the probability if in a random sample of 25 students from this said group and the average height is between 73 and 75 inches. So if you calculate it, it will be like this: 
<span>2P(Z<2)−1</span> To find the probability of Z, use the normal distribution table.
The value for Z being less than 2 is 0.9772. The final result is then<span><span>2(0.9772)−1=0.9544

What is a fraction of a fraction
Vikentia [17]
<h3> - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - </h3>

➷ When it comes to dividing fractions, there is a rule you must now.

It's called Keep Flip Change.

I'll give you an example:

\frac{2}{7} / \frac{4}{6}

Keep the first fraction exactly as it is

Flip the second fraction upside down (switch the numerator and denominator around)

Change the sign to a multiplication.

This is how it should look:

\frac{2}{7} *\frac{6}{4}

Now you just multiply them as you normally would to get an answer of:

\frac{12}{28}

➶Hope This Helps You!

➶Good Luck :)

➶Have A Great Day ^-^
