Answer:

A. f^-1(x) = x³ -12

Step-by-step explanation:

The inverse function can be found by solving ...

x = f(y)

x = ∛(y +12) . . . . . use the definition of f(x)

x³ = y +12 . . . . . . . cube both sides to eliminate the radical

x³ -12 = y . . . . . . . add -12 to isolate the y-variable

f^-1(x) = x³ -12 . . . matches choice A

An optical inspection system is used to distinguish among different part types. The probability of a correct classification of a

Whitepunk [10]

Answer: $\mu=2.88\ \&\ \sigma^2=0.115$

Step-by-step explanation:

Given : The probability of a correct classification of any part is : p=0.96

sample size : n= 3

The formula to find the mean and variance for binomial distribution is given by :-

$\mu=np\\\\\sigma^2=np(1-p)$

Let the random variable X denote the number of parts that are correctly classified.

The, for the given situation, we have

$\mu=3(0.96)=2.88\\\\\sigma^2=(3)(0.96)(1-0.96)=0.1152\approx0.115$

Hence, the mean and variance of X are 2.88 and 0.115 respectively.
