Answer:
D. Bell Curve
Step-by-step explanation:
Think about it like a test on a quiz. Let's say for the sake of the students, that most of the pupils got a score of 80. On the distribution, this would be the high point. Of course, less people got a 50 or 100, so these would be low points. This would create a kind of hill, or slope, which comes back down. This is also called a bell curve in many cases.
Answer:
a + c = 150
Step-by-step explanation:
adults + children = 150
a + c = 150
so to find the number of adults we need to subtract the number of children from the total number of attendees.
a + c - c = 150 - c the the number of adults is
a = 150 - c
833
Seravalle____________Chiesanuova______________San Marino

982
so the distance from Chiesanuova to Serravalle is :
982 - 833 = 149 miles <==
