The numbers of members in 6 yoga clubs are 75,69,72, 66, 70, and 86. Suppose a person in the club with 86 members transfers to the club with 66 members. A student claims
that the measures of center and the measures of spread will all change. Correct the student's error.
There are 6 elements in the set, so the IQR is the difference between the (select) v element and the
(select) The only values that are changing are the (select)
This will not affect the IQR.
The median is the average of the (select) elements and likewise remains unchanged. The mean
will also remain unchanged because the sum of all the elements doesn't change. The range will change
from 20 to
The standard deviation will also (select) because the value of
both the first and last elements will be closer to the mean.

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.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

two data sets with the same median will not have the same varaibility

step-by-step explanation:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
