Probability =
(number or amount of possible successes)(total number or amount of possible outcomes)

Area of any circle is (pi) x (radius squared)

Area of the whole board = (pi) x (13 squared) = 169 pi square inches

Area of the shaded region = (pi) x (5 squared) = 25 pi square inches

Probability = (success area) / (total possible area) = 25pi/169pi = <u>0.15 </u>(rounded)

Notice that if you do it my way ... keep 'pi' in the fraction ... you don't even
need to know what the value of 'pi' is, because there's one in the top and
bottom of the fraction, and they cancel.

ss7ja [257]

Answer:

The probability that the difference of the proportions (industrial - rural) is greater than 0.2 is 0.7054

Step-by-step explanation:

Solution

Given that:

n₁ = 1500

x₁ = 800

p₁ =800/1500 =0.533

q₁ = 1- 0.533 = 0.467

Thus,

n₂ =1000

x₂ = 300

p₂ = 300/1000 = 0.3

q₂ = 1-0.3 =0.7

So,

p₁ - p₂ = 0.533 - 0.3

=0.233

Now,

SE (p₁ - p₂ ) =√0.533 * 0467/150 + 0.3 * 0.7/1000

=0.0613

So,

p ( p₁ - p₂  > 0.2

= p ( Ƶ > 0.2 - 0.233/0.0613

p = ( Ƶ > - 0.54)

= 0.7054
