Answer:
z = -0.4.
Step-by-step explanation:
Here's the formula for finding the z-score (a.k.a. standardized normal variable) of one measurement 
of a normal random variable 
:
,
where
is the z-score of this measurement, - is the value of this measurement,
is the mean of the random normal variable, and
is the standard deviation (the square root of variance) of the random normal variable.
Let the length of a trout in this lake be 
inches.
.
, and
.
For this measurement, 
. Apply the formula to get the z-score:
.
Answer:
9.2
Step-by-step explanation:
to find the third side you need to use the Pythagorean Theorem, which is a²+b²=c². In this case, 6²+7²=c², or 36+49=c². c²=85, so do the square root of 85 to get the length of c, which is 9.2.
