The mean is the average, so add all the numbers and divide by 7 (7 terms).
-14 is the sum, divided by 7 = -2
The mean is -2.
64 - 9 = 55 \sqrt{55} = 7.4161984871
7.4161984871/2 ≈3.7
Did u get the answer please help me i am taking the test right now?!
Answer:
x = 5
Step-by-step explanation:
The 2 strokes through XM and MY indicate the segments are congruent, so
YM = MX , that is
8x - 24 = 3x + 1 ( subtract 3x from both sides )
5x - 24 = 1 ( add 24 to both sides )
5x = 25 ( divide both sides by 5 )
x = 5
