200 high school students were surveyed about whether they driving or taking the bus to school. 145 preferred driving. Find the margin of error with the given conditions. Round to four decimal places.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

the best estimate is 3 because   8 can only go into 24 3 times
