The table below shows the traffic fatality rate R, in fatalities per 100 million vehicle miles traveled, t years after 2010.t Find the equation of the regression line for Ras a function of t . (Round regression line parameters to two decimal places.) I t = years since 2010 I R = rate 0 1.11 1 1.10 2 1.14 3 1.09 4 1.07 R(t) =

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Which expression demonstrates the use of the commutative property of addition in the first step of simplifying the expression (-1+i)+(21+5i)+0

The number of chocolate chips in a bag of chocolate chip cookies is approximately normally distributed with a mean of 12611261 chips and a standard deviation of 118118 chips. (a) determine the 2626th percentile for the number of chocolate chips in a bag. (b) determine the number of chocolate chips in a bag that make up the middle 9696% of bags.
