Answer:
The probability a person will not live in a mobile home if they do not die as a result of the tornado is 0.9265.
Step-by-step explanation:
Denote the events as follows:
<em>X</em> = a person lives in a mobile home.
<em>Y</em> = a person dies as a result of tornado.
Given:
Compute the value of 
as follows:
Compute the probability that a person dies as a result of tornado as follows:
Then the probability that a person does not dies as a result of tornado is:
Compute the value of 
as follows:
Thus, the probability a person will not live in a mobile home if they do not die as a result of the tornado is 0.9265.
{x-(-3/4)}^2=3^2
(x+3/4)^2=9
{(4x+3)/4}^2=9
(4x+3)^2/16=9
(4x+3)^2=9*16
16x^2+2*4x*3+3^2=144
16x^2+24x+9=144
16x^2+24x+9-144=0
16x^2+24x-135=0
Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589
Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
Answer:
12 yards
Step-by-step explanation:
h = (3×198)/(½×11×9)
= 594/(49.5)
= 12 yds

To better combine like terms ... rearange the numbers
combine like terms (y's and constants cancel out)
Divide by 5
Plug this back into equations 5 and 7
