If you do 2,029 divided by 2 you will get the answer: 514.5 which is rounded to 515
Yes. 31 is a prime number.
It has no factors except ' 1 ' and itself.
Answer:
Step-by-step explanation:
InterQuartile Range is the difference in 3rd Quartile and 1st Quartile.
In box-plots, you can see two tails and a box. The left side of the box is the "first quartile" and the right edge of the box is "third quartile".
<u>For TOP BOX PLOT:</u>
3rd Quartile = 41
1st Quartile = 24
So, IQR (interquartile range) = 41 - 24 = 17
<u>For BOTTOM BOX PLOT:</u>
3rd Quartile = 35
1st Quartile = 28
IQR = 35 - 28 = 7
Difference in two IQRs is:
17 - 7 = 10
Correct answer is A
Answer:
the rotation angle is double the angle between the lines
Step-by-step explanation:
The Reflections in Intersecting Lines Theorem will tell you that the effective angle of rotation is double the angle between the intersecting lines. Here, the figure is effectively rotated 144°, not 72°. If a 72° rotation is desired, the lines need to intersect at an angle of 36°.
