Determine "n", the sample size needed to estimate the average weight for all second grade boys if we want the Margin of Error (MOE) to be exactly 1. Assume we know that the Standard Deviation of the data is 3. Find Sample Size "n"

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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)

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
