Answer:
however the meaning of math
Step-by-step explanation:
20+20
Answer:
yes
Step-by-step explanation:
f(x) = 6x² - 9x - 6 = 2x² - 3x - 2
= (x + 0.5)(2x - 4)
= [2x² - 4x] + [0.5(2x) + 0.5(-4)]
= 2x² - 4x + 0.5(2x) + 0.5(-4)
= 2x² - 4x + 1x + (-2)
= 2x² - 3x - 2
The z-score will be given by:
z=(x-μ)/σ
given that:
x=94
μ=mean=84.5
σ=standard deviation=4.4
thus
z=(94-84.5)/4.4
z=2.1591
The answer to your question is 8.1
