You are researching the growth of a species of fish. You gather a sample of fish and record the age in weeks of each fish and its mass in grams. The data is displayed on the grid below with the blue points. Age of fish (weeks) Mass of fish (e) 4. 8. 12 16 20 28 40 44 450 650 450 250 700 1000 1200 1350 You construct a linear model for the data, and your equation is y = 23.78z + 244.87 where y is the mass in grams of the fish and z is the age in weeks. a) Use the equation to identify the slope of the linear model. In the context of this problem what does the slope represent? [This box will not be graded but answers will be reviewed by your teacher.] b) Use the equation to identify the y-intercept of the linear model. In the context of this problem what does the y-intercept represent? [This box will not be graded but answers will be reviewed by your teacher.]

A. Give the regression equation in the form y=Asin(B(x-C))+D B. Use the regression equation to predict the average number of daylight hours in February 2017.

1a. Make a scatter plot of the table provided in the image. B. Write a linear/exponential equation that models this table provided in the image. C. Explain what the slope/multiplier means in the context of the problem. E. Use your model to predict when there will be 100 new cases (I have already done question 1a and have included it in my images. I mainly need help with questions C, D, and E)

Use Excel to develop a regression model to predict Annual Food Spending by Annual Household Income for those living in the Metro area only.     Suppose a household in the metro area has an annual income of $60,000.  Predict how much they spend on food per year.  Write your answer as a number and round to 2 decimal places.   Annual Food Spending ($) Annual Household Income           ($) Non mortgage household debt ($) Region:   1 = NE     2 = MW    3 = S       4 = W Location:   1 = Metro      2 = Outside Metro 8909 56697 23180 1 1 5684 35945 7052 1 1 10706 52687 16149 1 1 14112 74041 21839 1 1 13855 63182 18866 1 1 15619 79064 21899 1 1 2694 25981 8774 1 1 9127 57424 15766 1 1 13514 72045 27685 1 1 6314 38046 8545 1 1 7622 52408 28057 1 1 4322 41405 6998 1 1 3805 29684 4806 1 1 6674 49246 13592 1 1 7347 41491 4088 1 1 2911 26703 15876 1 1 8026 48753 16714 1 1 8567 55555 16783 1 1 10345 71483 21407 1 1 8694 50980 19114 1 1 8821 46403 7817 1 1…
