The answer is d because all angles in parallelogram are the same
The correct answer to this question is 0.1456. This is <span>the probability that X bar will be greater than Y bar. </span>Probability is the measure of how likely an event is. The formula is the ratio of the number of favorable outcomes to the total number of possible outcomes. Thank you for posting your question. I hope that this answer helped you.

Answer:
Step-by-step explanation:
if we wouldnt have the semicircle, all would be easy...
Area , A=10*30=300 ft^2
the semicircle has a diameter d=12 ft, than r=6
Area of the circle is Ac=3.14*r^2=113.10 ft^2
we need half of that
113.10/2=56.55
the area of the cover would be
300-56.55=243.45 ft^2
Answer:
Mean and IQR
Step-by-step explanation:
The measure of centre gives the central or the measure which gives the best mid term of a distribution. Based in the details of the box plot, the median is the value which divides the box in the box plot.
For company A:
Range = 25 to 80 with a median value at 30 ; this means the median does not give a good centre measure of the distribution ad it is very close to the minimum value. This goes for the Company B plot too; with values ranging from (35 to 90) and the median designated at 40.
Hence, the mean will be the best measure of centre rather Than the median in this case.
For the variability, the interquartile range would best suit the distribution. With the lower quartile and upper quartile both having reasonable width to the minimum and maximum value of the distribution.
