Step-by-step explanation:
means the inverse function
to find an inverse function, flip the x and y variables and solve for y
f(x) = 5x^3 - 6
y = 5x^3 - 6
x = 5y^3 - 6
x + 6 = 5y^3
(x + 6)/5 = y^3
= y
Answer:
The correct answer is "664".
Step-by-step explanation:
The given values are:
Margin of error,
E = 5%
i.e.,
= 0.05
Level of confidence,
C = 99%
i.e.,
= 0.99
Level of significance,
α = 0.01
From the z value table,
Critical z = 2.576
As we know,
The required sample size n will be:
=
On substituting the values, we get
=
=
=
=
i.e.,
=
