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

$R_r=\frac{P_U}{P_B}$

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

$R_r=480$

√272 is a real number, and the simplified expression of √272 is 4√17

<h3>How to simplify the expression?</h3>

The expression is given as:

√272

Expand

√272 = √16 * 17

Take the square root of 16

√272 = 4√17

Hence, the simplified expression of √272 is 4√17
