- Statistics report that the baby mortality rate from 1971 to 1995 can be modelled through the equation of D=6(0.96n). Where D represents the number of deaths per 1000 in children under 1 year of age. n represents the number of years since 1995. a) Indicate if the infant mortality rate is increasing or decreasing and explain your reasoning. b)If the trend continues what will the infant mortality rate be in the year 2008? c) When would the infant mortality rate be 3 per 1000? explainarrow_forwardWriting Other: 1.

In January2011, 4834 manatees were counted. (Source: Florida Fishand Wildlife Conservation Commission.)a) Using the year as the x-coordinate and thenumber of manatees as the y-coordinate, find anequation of the line that contains the two datapoints.b) Use the equation in part (a) to estimate the number ofmanatees counted in January 2010.c) The actual number counted in January 2010 was5067. Does the equation found in part (a) give anaccurate representation of the number of manateescounted each year?
