Region A = Segment Region B = Sector
2,200,000 = 88% Of X 25,000 = 1% Of X 2,500,000 = 100% Of X Answer = 2.5 * 10^
3a) The Number Of Blueberries In The Tub
3b) Complete The Table:
B 2 6 8 D 120 40 30
4a)
Answer = 2/
4b) All The Probabilities Must Equal 1, But They Add To 1.1.
5a) C = (0,6) D = (3,0)
5b) The Value Of The Y-Intercept Is 5. The X-Coordinate Of The Turning Point, T, Is 3.
90/5 = 18m/s
100,116 > 100,000 So Yes.
19a) 4X(3X + 2) - 2X^2(6 - 5/X) - 6X(3 + 7/X) = 12X^2 + 8X - 12X^2 + 10X - 18X - 42 = -42, Therefore An Integer.
19b) 8X^2 - 18X - 35 = 8X^2 - 28X + 10X - 35 = 4X(2X - 7) + 5(2X - 7) = (4X + 5)(2X - 7)
X = (6 +/- Sqrt(36 - 4 * 3 * -39)) / 2 = 6 +/- Sqrt(504)/ D = 6 E = 504 F = 6
1280 + 4480 = 5760 = 9/20 Of X 640 = 1/20 Of X
640 * 20 = 12800 People
24a) K = 21 * 6 = 126 Y = 126/12 = 10.
24b) The Value Of Y Is Less Than The Answer To The Part (A). 21 = A * 1/ A = 63 Y = 63 * 1/9 = 7
