An investment broker reports that yearly returns on common stocks are normally distributed with a mean of 12.41 percent and a standard deviation of 20.64 percent. (round all k amounts to 4 decimal places. negative amounts should be indicated by a minus sign. for z, use the inverse normal function and round to 4 decimal places, except when the percentile for part a is just 5, then you must interpolate.) (a) what percentage of yearly returns are at or below the 10th percentile of the distribution of yearly

step-by-step explanation:

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
