Answer:
=408x3+1556x2−4008x+1564
Step-by-step explanation:\
(8x−4)(3x+17)(17x−23)
Long piece: 5x + 3
Short piece: x
Long + Short = Total
5x + 3 + x = 45
6x + 3 = 45
6x = 42
x = 7
Long piece: 5x + 3 = 5(7) + 3 = 35 + 3 = 38
Answer: short = 7 ft, long = 38 ft
<span>A table is 3 feet and 2 inches wide
= 3(12) + 2 = 38 inches wide
</span><span>a chair is 25 inches wide
38 - 25 = 13 inches
answer: table is 13 inches </span><span>wider than the chair</span>
I the average score is 750 and standard deviation ( sigma ) is 50 points, then score 700 - 800 is between (750 - 1 sigma) and (750 + 1 sigma).
That is 34.1 % + 34.1 % = 68.2 % of the whole population.
2,000 · 0.682 = 1.364
We expect 1,364 students to score between 700 and 800 points.
