If you want the area of the entire trapeziod.
The formula for area of a trapeziod is:
1/2h(b₁+b₂)
So the equation applied to the trapeziod is:
2.5(20+12)
20+12 is 32. 32 multiplied by 2.5 is 80.

Answer:
(8,5)
Step-by-step explanation:
x=8
5*8-2y=30
40-2y=30 . subtract 40 from both sides
-2y=-10 . divide both sides by-2
y=5
Answer:
201.2
Step-by-step explanation:
area= s^2n
----------- ( 180)
4+9 ---------
( n )
Area equals S squared n over four plus nine times ( 180 over n )
Answer:
The sample proportion of 'successful' people is 
.
Step-by-step explanation:
The sample consist of 64 people and 48 of them are 'successful'. Hence, the proportion of 'successful' people is:
Where:
- People that forms the sample, dimensionless.
- People classified as 'successful', dimensionless.
Given that 
and 
, the sample proportion of 'successful' people is:
The sample proportion of 'successful' people is .
