According to recent UN figures, the annual gun homicide rate is 62.4 per one million residents in the US and 1.3 per one million
ss7ja [257]

Answer:

P_D=61.1*10^{-4}

R_r=480

Step-by-step explanation:

From the question we are told that

Homicide rate in US R_U=62.4\ per\ one\ million

Homicide rate in Britain R_B=1.3\ per\ one\ million

Generally the equation for probability of homicide is mathematically given as

P=\frac{R}{10^6}

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

P_U=\frac{62.4}{10^6}

P_U=62.4*10^{-4}

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

P_B=\frac{1.3}{10^6}

P_B=1.3*10^{-5}

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

P_D=P_U-P_B

P_D=62.4*10^{-4}-1.3*10^{-5}

P_D=61.1*10^{-4}

Therefore US annual homicide is P_D=61.1*10^{-4} greater than Britain's

b)Generally the Relative risk is R_r is mathematically given as

R_r=\frac{P_U}{P_B}

R_r=\frac{62.4*10^{-4}}{1.3*10^{-5}}

R_r=480

NISA [10]

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

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 :)
