Eighty percent of the students graduating from high school in a small iowa farm town attend college. the town's chamber of commerce randomly selects 45 recent graduates and inquires whether or not they will attend college. find the probability that at least 82% of the surveyed students will be attending college.

0.6368

Step-by-step explanation:

Given : The proportion of z-test for population mean :

Sample size :

We assume that this is normally distributed.

The test statistic for population proportion :-

Now, for , we have

By using the standard normal distribution table , the probability that at least 82% of the surveyed students will be attending college will be :-

Hence, the probability that at least 82% of the surveyed students will be attending college = 0.6368

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
