Answer:


Step-by-step explanation:
From the question we are told that

Homicide rate in Britain 
Generally the equation for probability of homicide is mathematically given as

Generally the equation for probability of homicide in US is mathematically given as


Generally the equation for probability of homicide in Britain is mathematically given as


a)Generally the difference b/w the probabilities P_D is mathematically given as



Therefore US annual homicide is
greater than Britain's
b)Generally the Relative risk is R_r is mathematically given as



-7x>4(-3x-5) do the distributive property
-7x>-12x-20 add 12 x to both sides
5x>-20 divide both sides by 5
x>-4
