Suppose wesley is a marine biologist who is interested in the relationship between the age and the size of male dungeness crabs. wesley collects data on 1,000 crabs and uses the data to develop the following least-squares regression line where x x is the age of the crab in months and ˆ y y^ is the predicted value of y y , the size of the male crab in cm. ˆ y = 9.1411 + 0.4775 x y^=9.1411+0.4775x what is the value of ˆ y y^ when a male crab is 23.2417 months old? provide your answer with precision to two decimal places

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs opens on day 1 with 6000 shares at $4.60 per share. the price of stock abc on day 8 begins at $3.50. the price of stock xyz on day 8 begins at $3.90. stock qrs opens on day 8 with a price of $4.50 per share. assume that each stock has the same number of shares that it opened with on day 1. what is the rate of change of this simple index over 1 week?

What is the average rate of change for this function for the interval from x=2 to x=4 ?
