From the table,
y - 72 = (64 - 72)/(24 - 12) (x - 12) = -8/12(x - 12) = -2/3(x - 12)
y - 72 = -2/3(x - 12)
y - 64 = (56 - 64)/(36 - 24) (x - 24) = -8/12 (x - 24) = -2/3(x - 24)
y - 64 = -2/3(x - 24)
y - 56 = (64 - 56)/(24 - 36) (x - 36) = 8/-12 (x - 36) = -2/3(x - 36)
y - 56 = -2/3(x - 36)
The answer is 253.............
27,36,45 all are numbers bigger than 20
Answer:
72.51
Step-by-step explanation:
Given that :
Lab score % = 23%
Each Major test % = 22.5%
Final exam % = 32%
Score :
Lab score = 96
First Major test = 64
Second major test = 62
Final exam = 69
Hence,
Weighted average = Σ(weight % * score)
Weighted average = Σweight_1*score_1 +.. Weight_n * score_n)
(0.23 * 96) + (0.225 * 64) + (0.225 * 62) + (0.32 * 69) = 72.51
4 pack is better because, with me 4 pack you can get more and for less money.
