The list of the buildings arranged in the order from shortest to tallest

Marina 101
The Wuhan Center
The Zifeng Tower
The Shanghai tower

The heights in feet shows that

2072 feet(is the tallest) > 1,476 feet > 1,437 feet > 1400 feet (is the least)

<h3>How to arrange the buildings from shortest to tallest</h3>

Given that the z scores are 127 for The Shanghai tower and -0.84 for Marina

z score = (X - mean) / standard deviation

X = z score * standard deviation + mean

The Shanghai tower

= 1.27 * 318.31 + 1667.25 = 2071.5037 feet

Marina 101

= -0.84 * 318.31 + 1667.25 = 1399.8696 feet

The Zifeng Tower

= 1,476 feet

The Wuhan Center

= 1,437 feet

comparing the heights

2072 feet > 1,476 feet > 1,437 feet > 1400 feet

The probability density function of the time to failure of an electronic component in a copier (in hours) is f(x)= e^-x/100 /100

Georgia [21]

Answer:

Check the explanation

Step-by-step explanation:

The fundamentals

A continuous random variable can take infinite values in the range associated function of that variable. Consider $f\left( x \right)f(x)$ is a function of a continuous random variable within the range $\left[ {a,b} \right][a,b]$ , then the total probability in the range of the function is defined as:

$\int\limits_a^b {f\left( x \right)dx} = 1 a∫b f(x)dx=1$

The probability of the function $f\left( x \right)f(x)$ is always greater than 0. The cumulative distribution function is defined as:

$F\left( x \right) = P\left( {X \le x} \right)F(x)=P(X≤x)$

The cumulative distribution function for the random variable X has the property,

$0 \le F\left( x \right) \le 10≤F(x)≤1$

The probability density function for the random variable X has the properties,

$\\\begin{array}{c}\\{\rm{ }}f\left( x \right) \ge 0\\\\\int\limits_{ - \infty }^\infty {f\left( x \right)dx} = 1\\\\P\left( E \right) = \int\limits_E {f\left( x \right)dx} \\\end{array} f(x)≥0$
