The residential energy consumption survey found in 2001 that 47% of american household had internet access. a market survey organization repeated this study in a certain town with 25,000 households, using a simple random sample of 500 households: 239 of the same households had internet access. a) the percentage of households in the town with internet access is estimated at ; this is likely to be off by or so. b) if possible, find a 95%-confidence interval for the percentage of all 25,000 households with internet access. if this is not possible, explain why or why not.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

hope this !

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
