A coin is tossed two times. what is the probability of getting tails two times in a row?

goldfiish [28.3K]

It's a conditional probability: (We know that the probability of getting 1 tail or 1 head is equal to 1/2)

Probability ( Tail AND Tail) = 1/2 x 1/2 = 1/4

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:

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

A boat is traveling at 43.2 m/s. It then goes down a faster part of the river and is now going 144

Marina86 [1]

Answer:

Step-by-step explanation:

boat was at 43.2 m/s speed increase to 144 m/s

if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s², it would take the same amount of time

25.2 m/s² × x seconds = (144 - 43.2) m/s solve for x in seconds

x seconds = 100.8 m/s / 25.2 m/s²

x seconds = 4 (m/s /ms²) = 4 (m/s × s²/m) = 4 seconds the units match

x = 4 seconds
