Answer:
about 1,459,063 ft^2
Step-by-step explanation:
The area of the triangle is ...
A = (1/2)bh = (1/2)(1490 ft)(541 ft) = 403045 ft^2
The area of the trapezoid is ...
A = (1/2)(b1 +b2)h = (1/2)(1490 ft +921 ft)(876 ft) = 1056018 ft^2
Then the total land area is about ...
403,045 ft^2 +1,045,018 ft^2 = 1,459,063 ft^2
Total voters = 900
Republicians =369
Democrats =468
Independents = 63
Sample size n =90
a) The expected value of the number of Republicans in the sample is
=
b) The chance the sample contains only Republicans and Democrats is
= (no of republicians+democrats)/total people
c)
Answer: No, this relation is not a function.
Two of the points with the same Y axis have different X values (as stated in answer A)
okk thanks for free points
