You know you have 2 building A and B so divide the total hight of both towers by 2; total of 7650765. You know Building A is 20020 feet shorter thus you subtract that from 7650765.
Building A is 7,630,745 feet tall
Building B is 7,670,785 feet tall

Answer:
The probability a salamander has a length between 12.2cm and 16.5cm is 0.6930
Step-by-step explanation:
We start by finding the z-score of each
Mathematically;
z-score = (x - mean)/SD
for 12.2 cm
z-score = (12.2 - 15)/2 = -2.8/2 = -1.4
For 16.5 cm
z-score = (16.5 -15)/2 = 1.5/2 = 0.75
So the probability we want to calculate is;
P( -1.4 < z < 0.75)
we can calculate this using the normal distribution table
Mathematically;
P( -1.4 < z < 0.75) = P( z < 0.75) - P( z < -1.4)
= 0.2263 + 0.30738
= 0.69262
So, Bill made $255 in 17 weeks, and if you divide it, he made $15 per week. 195/15 and you will get your answer. I hope this helps.
