Answer:
a. ⅛
b. ⅜
c. -⅜
Step-by-step explanation:
a. There are 8 units from 0 to -1, and also 8 units from 0 to 1.
Given that the numberline is divided I to equal segments, therefore, each segment will be of the following equal length:
¹/8 * 1 = ¹/8
Therefore, a segment = ⅛
b. Point N is 3 units from 0.
Each unit = 1 segment = ⅛
Point N would represent:
3 * ⅛ = ⅜
c. The opposite of point N, ³/8, is the same distance that would be covered to our left from 0.
-³/8 is the opposite of point N, ⅜
Answer: 91
Step-by-step explanation: I assume you had a typo and mean what did Ana need on the 5th quiz since you only listed 4 quiz scores.
(74 + 92 + 83 + 100 + x)/5 = 88
(349 + x)/5 = 88
((349 +x)/5) x 5 = 88 x 5
349 + x = 440
x = 440-349
x = 91
