Hello!
a) The population of interest is the registered voters of the city of Raleigh.
b) This population is finite and its size is 10400 voters.
c) The sample was taken by making a telephone poll, calling 400 registered voters.
d) The sample size is n= 400 voters
The number of people that answered they'd vote for Brown are 151, so the sample proportion of voters that would vote for bron is:
p= 151/400= 0.3775 ≅ 0.38
e) To know how many people is expected to vote for Brown based on the results of the telephone poll you can do the following calculation:
10400*0.38= 3952
Based on the information obtained from the sample, it is expected that only 3952 voters will vote for Brown.
Answer:
A) (Triangle) So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
B) We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
C)The parallelogram area can be calculated, using its base and height.
Area = ½ × d1 × d2 sin (y)
All Formulas to Calculate Area of a Parallelogram
Using Base and Height A = b × h
Using Trigonometry A = ab sin (x)
Using Diagonals A = ½ × d1 × d2 sin (y)
D)Area of a trapezoid is found with the formula, A=(a+b)/2 x h. Learn how to use the formula to find area of trapezoids.
Hope this helps!
All the love, Ya boi Fraser :)
