Suppose a vote was conducted in a small town of 5000 people. among a random sample of 100 votes, 55 were in favor of a proposition while 45 were against it. so the margin of victory of the proposition is estimated to be 10% = 55% − 45%. denote by p the percentage of the votes in favor of the proposition. (a) provide an estimate ˆp and construct a 95% confidence interval of p. (b) express the estimated margin of the victory in terms of ˆp. (c) calculate the standard error of the estimated margin of the victory from this vote and construct a 95% confidence interval.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

a rotation about point l

step-by-step explanation:

quizlet

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
