The solution would be like
this for this specific problem:
<span><span>9 ! </span><span>
<span>------- </span>
<span>6 ! 3! </span>
<span>9 x 8 x 7 </span>
<span>-------------- </span>
<span>6 </span></span></span>
504 / 6 = 84
<span>So the value of 9C6 is <span>84.</span></span>
<span>If you have any other questions, please don’t hesitate to ask
again.</span>
The answer is 1.464 x 10^8
From the given statement above, the information that can be extracted from the data is the mean which is equal to 9 % , SD equal to 4%, n is equal to 20. we can also get the variance from SD. also, we can also determine the z-score of the data which is important in the distribution.
It has been given that y varies inversely with x, therefore the equation for this relationship is as follows;
y =

\
when y = -18 and x = 6
-18 = k/ 6 ---1)
We need to find x when y = 5
5 = k/x
when we divide 1)/2), k gets cancelled

x = -18*6/5
x = -21.6
when y = 5, then x = -21.6
-1 3/8 and 2 4/5
-1 15/40 and 2 32/40
1 17/40
I hope that helps you!
