No, because all sides are not congruent. The answer is B.

No. It is not a square. Clearly this quadrilateral does not match all of the critera needed to fit the image/idea of a square. Although all of the vertices are 90 degree angles and the polygon is indeed a quadrilateral, the sides of the figure are not all the same length. That image is not one of squarish preportions. Therfore, it is not a square.

P.S. I tried to add in mathmatic words. Im not that much of a knowitall. Hope they get u an A+!!!

$4.55 Add 5.95 and 9.76. You should get 15.45. Then you do 20-15.45=4.55

Describe the center and spread of the data using either the mean and standard deviation or the five-number summary. Justify your

Answer:

The distribution is skewed, so use the five-number summary. range: 38, median: 16, half of the data are between 9.5 and 25

Step-by-step explanation:

In the picture attached the histogram is shown. We can see that data is skewed to the right, so we have to use the five-number summary. The range of the data is 39 - 1 = 38 (subtraction of the maximum value to the minimum value); the median is (15 + 17)/2 = 16 (if you order the values, 15 and 17 are in the middle); quartile 1 is 9.25 and quartile 3 is 25.5 (see diagram of box and whisker attached), then half of the data are between those values.
