10 is the population mean.
The SRS he takes, the simple random sample, is the 60 horses with colic. The population would be all of the horses seen at the clinic. Therefore the mean of the horses seen at the clinic would be the population mean.
Identity to verify:
Recall that
Divide both sides by and we get
or
So if we multiply the numerator and denominator of
by , we get
Then as long as , we can cancel terms to end up with
and establish the identity.

Using Isosceles triangle theorem we can determine that JI = JK
Thus
5x + 4 = 2x+7
3x = 3
x=1
Plug it back into the eqution for JK
2(1) + 7 = JK
9 = JK
