The area of the triangle is 27cm.
The probability is 0.7734.
The z-score for this value is given by:
z =(X-μ)/σ = (83-101)/24 = -18/24 = -0.75.
Using a z-table (http://www.z-table.com) we see that the area to the left of this (lower than) is 0.2266. We want the percentage that will score higher on the test, so we subtract fro 1:
1 - 0.2266 = 0.7734.
Answer:
$14.6
Step-by-step explanation: because adding how all they are in total.
85,300,000 that's the answer you can put
31,900,000+53,400,000=85,300,000 tons
