10% of the downtown residents of a town in the Plains live in mobile homes. Based on data from past tornadoes, if a tornado goes
tia_tia [17]

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:

P(X)=0.10\\P(Y|X) = 0.30\\P(Y|X^{c})=0.02\\

Compute the value of P(Y^{c}|X^{c}) as follows:

P(Y^{c}|X^{c})=1-P(Y|X^{c})\\=1-0.02\\=0.98

Compute the probability that a person dies as a result of tornado as follows:

P(Y)=P(Y|X)P(X)+P(Y|X^{c})P(X^{c})\\=(0.30\times0.10)+(0.02\times(1-0.10))\\=0.03+0.018\\=0.048

Then the probability that a person does not dies as a result of tornado is:

P(Y^{c})=1-P(Y)\\=1-0.048\\=0.952

Compute the value of P(X^{c}|Y^{c}) as follows:

P(X^{c}|Y^{c})=\frac{P(Y^{c}|X^{c})P(X^{c})}{P(Y^{c})}=\frac{0.98\times(1-0.10)}{0.952}=0.9265

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.

The perimeter of a rectangle with a length of 10 units which equation can be used to find the width of the rectangle
sergeinik [125]

Answer:

2w + 20 = 55

Step-by-step explanation:

Here is the full question

The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?

w + 10 = 55

w + 20 = 55

2w + 10 = 55

2w + 20 = 55

The perimeter of a rectangle's formula is = 2 ( length + breadth)

from the question ,

perimeter is 55 and length is 10

2(10 + w) = 55

20 + 2w = 55
