Consider random samples selected from the population of all female college soccer players in the united states. assume the mean height of female college soccer players in the united states is 66 inches and the standard deviation is 3.5 inches. which do you expect to have less variability (spread): a sampling distribution with sample size n = 100 or a sampling distribution with sample size n = 20?
a. both sampling distributions will have the same variability. b. the sampling distribution with sample size n=20 will have less variability. c. the sampling distribution with sample size n=100 will have less variability

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
