1. Write a linear/exponential equation that models this situation (consistent with the data provided). Time is the explanatory variable, and New Covid Cases is the response variable. B) Explain what the slope/multiplier (consistent with your choice above) means in this context of the problem. Be sure to use units and to write a clear sentence. Hi there, I have provided an image of the data table and my scatter plot. I just need help identifying the exponential equation and multiplier that fits the data.

9. The chief executive of Rex Cars wants to investigate the relationship between the number of new car sales and the amount of money spent on advertising. She collects data from company records on the number of new car sales, y, and the cost of advertising each year, x (£000). The data are shown in the table below. Cost of advertising (£000), (x) Number of new car sale, Year (y) 2005 120 4240 2006 126 4380 2007 132 4420 2008 134 4440 2009 137 4430 2010 144 4520 2011 148 4590 2012 150 4660 2013 153 4700 2014 158 4790 a. Use your calculator to find the equation, y = a + bx, of the line of best fit (the least squares regression line of y on x). b. Interpret the value of a. c. Calculate the predicted number of car sales made in 2015 if the company spends £163 000 on advertising.

How much should a healthy Shetland pony weigh? Let x be the age of the pony (in months), and let y be the average weight of the pony (in kilograms). x 3 6 12 20 26 y 60 95 140 160 189 (a) Make a scatter diagram of the data and visualize the line you think best fits the data. Flash Player version 10 or higher is required for this question. You can get Flash Player free from Adobe's website. (b) Would you say the correlation is low, moderate, or strong? low moderate strong Would you say the correlation is positive or negative? positive negative (c) Use a calculator to verify that x = 67, x2 = 1265, y = 644, y2 = 93,546, and xy = 10,544. Compute r. (Round your answer to three decimal places.) As x increases from 3 to 26 months, does the value of r imply that y should tend to increase or decrease? Explain your answer. Given our value of r, y should…
