Which polygon appears to be regular?

a.
figure a

b.
figure b

c.
figure c

d.
figure d

Figure A is regular polygon.

Step-by-step explanation:

We are given four different figure. We need to select one regular figure.

Regular Polygon: It is figure whose sides, angles and exterior angles are equal.

Figure A: It is square of two dimensional figure. Square is regular figure.

It is regular polygon.

Figure B: It is shape of parallelogram whose opposite sides are parallel and equal. But adjacent sides are unequal. hence, It's not regular polygon.

Figure C: It is right angle triangle. Right angle triangle never be regular polygon. because all three sides are not equal.

Figure D: It is trapezoid. Trapezoid never be a regular polygon because their opposite sides never be equal.

Hence, Figure A is regular polygon.

step-by-step explanation:

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
