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

What is the radius of a cylinder with a volume of 3,165.12 cubic centimeters and a height of 7 centimeters?
leonid [27]

Answer:

Radius = 12 cm

Step-by-step explanation:

Given:

Volume of the cylinder is, V=3165.12 cm³

Height of the cylinder, h= 7 cm

Let the radius be r

Using the formula for volume of cylinder,

V=\pi r^2h

Plug in 3165.12 for V, 7 for h and solve for r.

3165.12=\pi r^2(7)\\3165.12=\frac{22}{7}\times 7\times r^2\\3165.12=22r^2\\r^2=\frac{3165.12}{22}\\r^2=143.869\\r=\sqrt{143.869}=11.99\approx=12\textrm{ cm}

Therefore, the radius of the cylinder is nearly 12 cm.

A new washing machine used 3 2/4 gallons of water per full load to clean cloths. If John washed 2 2/3 loads of clothes, how many
kumpel [21]
We know that
3 2/4  -------------> is (3*4+2)/4--------> 14/4-------> 7/2
2 2/3 --------------> is (2*3+2)/3--------> 8/3

if a new washing machine used 7/2 gallons of water ------------> one full load <span>cloths
</span> X gallons of water------------------------------------------------------> 8/3 of load cloths<span>
X=(8/3)*(7/2)---------> X=56/6------->28/3 gallons of water
28/3--------> 9 1/3 gallons of water

the answer is
 </span>9 1/3 gallons of water
