Using the normal distribution, it is found that due to the greater z-score, Stewart caught the longer fish relative to the same specie.
<h3>Normal Probability Distribution</h3>The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
To find who caught the longer fish relative to the same specie, we need to find out who had the higher z-score.
Stewart caught a bluefish with a length of 322 mm, hence the parameters are as follows:
The z-score is:
Z = 1.41
Gina caught a pompano with a length of 176 mm, hence the parameters are as follows:
The z-score is:
Z = 0.75.
Hence Stewart caught the longer fish relative to the same specie.

Answer:
D) 57.5°
Step-by-step explanation:
As the question is not complete. So, let's suppose it is a right angle triangle then, we can apply Pythagoras theorem to calculate the hypotenuse or the third side.
Pythagoras Theorem = =
a = 7 and b = 11
= 49
= 121
Plugging in the values, we will get:
= 49 + 121
= 170
c =
To calculate the unknown angle B, we can use law of sine.
Law of sine = =
=
So,
=
=
Sin90 = 1
sinB =
B = (
)
B = 57.5°
