Answer:

r^2 = 0.826^ 2 =.6822

r^2 = a measure of how strong the ("how fit") the relationship is

it is always positive between 0 and 1

Step-by-step explanation:

coefficient of determination = r^2

r^2 = 0.826^ 2 =.6822

Gina and Stewart are surf-fishing on the Atlantic coast, where both bluefish and pompano are
viktelen [127]

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 \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • 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:

X = 322, \mu = 267, \sigma = 39

The z-score is:

Z = \frac{X - \mu}{\sigma}

Z = \frac{322 - 267}{39}

Z = 1.41

Gina caught a pompano with a length of 176 mm, hence the parameters are as follows:

X = 176, \mu = 155, \sigma = 28

The z-score is:

Z = \frac{X - \mu}{\sigma}

Z = \frac{176 - 155}{28}

Z = 0.75.

Hence Stewart caught the longer fish relative to the same specie.

30( \frac{1}{2} x - 2) + 40( \frac{3}{4} y - 4) =  \\

(30 \times  \frac{1}{2} x) -( 30 \times 2 )+ (40 \times  \frac{3}{4} y )- (40 \times 4 )=  \\

15x - 60 + 30y - 160 =  \\

15x + 30y - 220

The correct answer is Option Three .
