B 216 because if you multiply pi with the answer you get 678.58
The proportion of buses traveling more than 900 miles would be 0.0485; multiply this by the total number of buses and you will have your answer.
We find the z-score associated with 900 miles:
z = (X - μ)/σ = (900-830.11)/42.19 = 1.66
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of this, less than this, is 0.9515. This means that the area under the curve to the right of this, greater than this, would be 1-0.9515 = 0.0485.
The team gained a total of 3 yards. That is because they first gained 8 (0 + 8), then lost 3 (8 - 3).
Answer:
c= -4
Step-by-step explanation:
4+c=0
1)c+4=0: Rearrange the expression
2) c=0-4: Separate the constants and variables
3) c= -4: Add or subtract zero
Hope that helps :)
