Two cooling fans are installed in some laptop computers. Suppose the reliability of each cooling fan is 0.92. What percent impro

wlad13 [49]

Answer:

Step-by-step explanation:

Given that:

Reliability of each = 0.92

r = 0.92

1 - (1 - r)(1 - r) = 1 - (0.08)(0.08) = 1 - 0.0064 = 0.9936

Percentage improvement :

1 - (0.9936) / r

1 - (0.9936 / 0.92)

1 - 1.08

= - 0.08

= 0.08 / 100 = 8%

2/5 of a number is what percentage of that number?

Law Incorporation [45]

Answer:

40%

Step-by-step explanation:

In order to find percent, you can set up the fraction 2/5 to the equation x/100.

$\frac{2}{5}=\frac{x}{100}$

Then solve using algebra to cross-multiply.

$(2*100)=(x*5)$

$200 = 5x$

$x = \frac{200}{5} = 40$

so the answer is 40%.
