We know that two sides of the rectangle are 13cm. To find the area, we need to find h. It looks like h is 1/3 of the longer side, so 13 divided by 1/3 is 4.3. 13 times 4.3 is 55.9cm. I hope this helps!

HARDEST MATH PROBLEM!

Marianna [84]

The result of subtracting and simplifying the rational expression in its fully factored form is $\frac{4n^{2} +17n - 195 }{5(n^{2} -25)}$

<h3>Simplifying an expression in fully factored form</h3>

From the question, we are to subtract the rational expressions and express in the factored form

The given expression is

$\frac{n^{2} + 5n - 36 }{n^{2} -25} - \frac{n^{2} +8n +15 }{5n^{2} -125}$

Factor 5n² - 125

$\frac{n^{2} +5n - 36 }{n^{2} -25} - \frac{n^{2} +8n +15 }{5(n^{2} -25)}$

$\frac{5(n^{2} +5n - 36) - (n^{2} +8n +15) }{5(n^{2} -25)}$

$\frac{5n^{2} +25n - 180 - n^{2} -8n -15 }{5(n^{2} -25)}$

Simplify

$\frac{4n^{2} +17n - 195 }{5(n^{2} -25)}$

Hence, the expression is $\frac{4n^{2} +17n - 195 }{5(n^{2} -25)}$

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.
