Answer:
Final answer is 
Step-by-step explanation:
We have been given a table containing a list of few places that are either city or in North America.
Total number of places in that list = 7
That means sample space has 7 possible events.
Given that a place from this table is chosen at random. Let event A = The place is a city.
Now we need to find about what is 
.
That means find find the probability that chosen place is not a city.
there are 3 places in the list which are not city.
Hence favorable number of events = 3
Then required probability is given by favorable/total events.
To find the mean you add all the numbers then divide the sum by how many numbers there are :
1)Ford School
21+19+20=60
there are 3 numbers in the equation so you divide 60 by 3 :
60÷3=20
the mean for Ford School is 20
2)Carter School
41+36+37=114
there are 3 numbers in the equation so you divide 114 by 3 :
114÷3=38
the mean for Carter School is 38
hope this helps

229.7125
Step-by-step explanation:
Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees, so no.
Answer:
33 feet
22 feet
Step-by-step explanation:
Let the longer piece be x
Therefore the shorter piece is (2/3)x
x + (2/3)x = 55 Combine the left 2 terms.
(3/3)x + (2/3)x = 55 Add
(5/3)x = 55 Multiply both sides by (3/5)
(3/5) * (5/3)x = (3/5)*55
x = 33
The larger piece is 33 feet
The smaller piece is (2/3) * 33 = 22 feet
