Answer:

4,096 ways

Step-by-step explanation:

Assuming that all questions have to be answered, there are two ways to answer each of the 12 questions (True or False). The total number of possible answers is given by:

$n=2^{12}\\n=4,096\ ways$

A 12-question true-false exam can be answered in 4,096 different ways.

Suppose that two electronic components in the guidance system for a missile operate independently and that each has a length of

lord [1]

Answer:

The probability density function for the average length of life of the two components is $f(x) = 0.5e^{-0.5x}$

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following probability density:

$f(x) = \mu e^{-\mu x}$

In which $\mu = \frac{1}{m}$ is the decay parameter.

Each missile has a length of life governed by the exponential distribution with mean 1 (with measurements in hundreds of hours). Find the probability density function for the average length of life of the two components.

2, each with mean 1 means that $m = 2*1 = 2, \mu = \frac{1}{2} = 0.5$

So the probability density function is:

$f(x) = 0.5e^{-0.5x}$

Tanzania [10]

Answer: unsubstantiated.

This is, the statement "Some of Tucson's residents are blue eyed children" cannot be inferred from the two original statements.

Because the subset of "Tucson's residents that have blue eyes" and the subset of "Tucson's residents that are children" might or might not have common elements.
