Answer:
The steps to finding the upper and lower quartiles are given in the first choice.
1. Order the data from least to greatest. If you don't do this, the data is random.
2. Find the median - you will do this so that you can find the midpoint of the data set (half of of the data is smaller and half of the data is larger).
3. Find the lower quartile - this is the half of the lower half of numbers; think of it as breaking the lower half of the data into 2 sections.
4. Find the upper quartile - this is the half of the greater half of numbers; this will break the upper half of the data into 2 sections.
Answer: (1.5, -5)
Step-by-step explanation:
If you use the midpoint formula and plug in your coordinates, you’ll get (-6+9/2, -3+(-7)/2). Simplify and you get (3/2, -5) which is also (1.5, -5).
A. 4 (is the only factor for expression -48xyz -24xy +40)
Answer:
45°
Step-by-step explanation:
Segments GJ and HK intersect at F.
That makes angles JFK and GFH vertical angles and congruent.
An arc has the same measure as its central angle.
m<GFH = 45°
m<JFK = m<GFH
m<JFK = 45°
Multiply the square root of 3 by the square root of 2 and itself.
The 3 cancels itself out and then you get A
