Ateacher gives a test to a large group of students. the results are closely approximated by a normal curve. the mean is 74, with a standard deviation of 8. the teacher wishes to give a's to the top 8% of the students and f's to the bottom 8%. a grade of b is given to the next 16%, with d's given similarly. all other students get c's. find the bottom cutoff for a grade of c.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

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)
