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



Answer:
a = - 5, a = - 3
Step-by-step explanation:
Given
a² + 8a + 15 = 0 ← in standard form
(a + 3)(a + 5) = 0 ← in factored form
Equate each factor to zero and solve for a
a + 3 = 0 ⇒ a = - 3
a + 5 = 0 ⇒ a = - 5
X < = 1 or x > 8
closed circle on 1, shaded to the left
open circle on 8, shaded to the right
so, you just use the x's from the table and plug them into the equation to find the y.
y=(1)+9
y=10
y=(2)+9
y=11
y=(3)+9
y=12
y=(4)+9
y=13
i hope this helps :)
