C) Suppose you take a sample of 250(n) students. Suppose the sampling
distribution of sample means follow normal distribution, center (same as
population mean u )and standard-deviation( ). Then,
i) Find the probability that a sample mean is below 52.5 inches.
j) Find the range of sample means to be in the middle 95% area.

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.

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

f(x)=2/3x-8, which give g(x) the greatest value.
