cientists are studying the population of a particular type of fish. The table below shows the data gathered over a five-month time period. Use the data to answer questions 5-9.

number of months number of fish

0 8

1 39

2 195

3 960

4 4,738

5 23,375

5. what does the scatterplot of the data show?

1. strong positive linear relationship

2. a strong negative linear relationship

3. a curve that represents exponential growth

4. a curve that reprents ecponential decay

I select number 3

6. Complete an exponential transformation on the y-values. What is the new value of y when x+5?

1. 4.3688

2. 3.6756

3. 0.6990

4. 3.3757

I select #3

7. Find the linear transformation Model

1. log y hat=0.6935•logx + 0.9013

2. log y hat=0.9013x+0.6935

3. log y hat=0.6935x+0.9013

4.

log y hat=0.9013•logx+0.6935

8. Use the linear transformation model to predict the number of fish in 12 months.

this is where I need help.

9. A power model is shown below. Determine the residual for the observed data x=7 and y=70

log y hat=1.6+0.31log x

1.71.37

2.1.37

3.1.85

4.-1.37

I select 4
