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

I need help I don't understand this one math is my hardest subject
aksik [14]
In order to name the coordinates, you read the X axis first and then the Y axis. So A would be (-4, 4). B would be (-4, 6). C would be (2, 4). 

They are not congruent because each angle is a different measure. 

Hope this helped! :)
