Using the normal distribution, it is found that due to the greater z-score, Stewart caught the longer fish relative to the same specie.
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
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:
Z = 0.75.
Hence Stewart caught the longer fish relative to the same specie.

Answer:
4
Step-by-step explanation:
The third graph.
The equations for the lines will be
P(x) = 2x-4
l(x) = -2x-4
When x = 0 both of these functions equal -4. The only graph where this happens is the third one.
You can check this by looking at the slopes and plugging in points.
