N a survey of 1227 people, 828 people said they voted in a recent presidential election. Voting records show that 65% of eligible voters actually did vote. Given that 65% of eligible voters actually did vote. A) Find the probability that among 1227 randomly selectedvoters, at least 828 actually did vote.

Step-by-step explanation:

Given proportion of eligible voters did vote = p = 0.65.

In a survey of 1227 people 828 people said they voted. Proportion of people voted in sample of 1227 = 828/1227 =0.6748

Let p be a distribution which represents the proportion of people voted. In given sample with size 1048, it is large enough that np and n(1-p) are greater than 10. So, we can assume that it fo...

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
