AB - C2 = (x2)(3x + 2) - (x-3)2
AB - C2 = 3x3 + 2x2 - (x2 -6x +9)
AB - C2 = = 3x3 + 2x2 - x2 + 6x - 9
AB - C2 = = 3x3 + x2 + 6x - 9
Multiplication comes before any subtraction...so do 10 x 5 first
Answer:
Negative infinity to infinity, 3 to infinity.
Answer:
87
Step-by-step explanation:
Population standard deviation = σ = 37 grams
Confidence interval = 94%
(1-α)×100% = 94
⇒α = 0.06
From table z table and interpolation
z = 1.881
L = Confidence interval length = 15
N = Number of samples

∴ Number of turtles must she must weigh is 87
