Answer:
D. The mean for the 8th grade players is 3 times the mean for the 6th grade players. & E. The data set distribution for the 8th grade players is symmetric.
1. 343x³ - 8 = 0
343x³ + 98x² - 98x² + 28x - 28x - 8 = 0
343x³ + 98x² + 28x - 98x² - 28x - 8 = 0
7x(49x²) + 7x(14x) + 7x(4) - 2(49x²) - 2(14x) - 2(4) = 0
7x(49x² + 14x + 4) - 2(49x² + 14x + 4) = 0
(7x - 2)(49x² + 14x + 4) = 0
7x - 2 = 0 or 49x² + 14x + 4 = 0
+ 2 + 2 x = -(14) ± √((14)² - 4(49)(4))
7x = 2 2(49)
7 7 x = -14 ± √(196 - 784)
x = ²/₇ 98
x = -14 ± √(-588)
-98
x = -14 ± 14i√(3)
-98
x = -14 + 14i√(3) or x = -14 - 14i√(3)
-98 -98
x = ¹/₇ - ¹/₇i√(3) or x = ¹/₇ + ¹/₇√(3)
x = ¹/₇ ± ¹/₇i√(3)
Solution Set: {¹/₇ ± ¹/₇i√(3), ²/₇}
2. 64x³ = 0
64 64
x³ = 0
∛(x³) = ∛(0)
x = 0
Solution Set: {0}
Answer: 3 units right 6 units up
Step-by-step explanation:
coordinate B was first (3,3)
then became (6,9)
X axis is 3 which is left and right
Y axis is also 3 which is up and down
right = positive left= negative up=positive down=negative
the math
you have to add 3 to the right to get positive 6
so the coordinates so far are (6,?)
then you need to add 6 on the y axis for the coordinates to be (6,9)

Total flour used = Sum of all the cups
Total = 2 cups + 0.5 cups + 1.75 cups
= 4.25 cups of flour
4.25 cups of flour was used.
Hope this explains it.
The model of the bridge and the actual bridge are similar solids. The lengths of corresponding sides of similar figures are in proportion.
5/25 = 6/30 = 8/40 = 1/5
Answer: 1/5
