The first one would be A, the lower quartile is given, because the 5 number summary has been given. The second one would be 99, because 97 gives 89.6 and 98 gives 89.8. And the third one would be there are exactly 3 students with 4 pairs of shoes. Hope this helps! If you need anything else let me know.
Answer:

Step-by-step explanation:
Answer: B
Step-by-step explanation:
Since 
, it follows that 
Use the law of cosines. Let 
be the distance between the docks, which forms a third leg of a triangle for which the angle opposite it has measure 45 degrees. The other two legs have lengths 400 ft and 500 ft. So
9514 1404 393
Answer:
∠U = 60°
∠W = 30°
Step-by-step explanation:
The side length ratios are ...
1 : √3 : 2
so you know this is one of the "special triangles." Its angle measures are 30°, 60°, and 90°. The smallest angle (W) is opposite the shortest side (7).
The angle measures are ...
m∠U = 60°
m∠W = 30°
[the UW measure is correct]

<em>Additional comment</em>
Your calculator can tell you the arctangent of √3 or 1/√3. Be sure to set it to degrees mode.
