Answer:

5 feet 4 inches is 64 inches

it is also 162.56 in centimeter.

Step-by-step explanation:

There are 12 inches in a feet

12 x 5 = 60

60 + 4= 64 inches.

If you are look for 5ft 4 in in cm.

64 x 2.54=162.56 cm.

Answer:162.56cm

Step-by-step explanation:

There are 12 inches in a foot so

12•5= 60.

60+4

Now multiply 64 by 2.54 to convert to cm.

Suppose that, for every lot of 100 computer chips a company produces, an average of 1.4 are defective. Another company buys many

Vesna [10]

Answer:

$P(X\leq 3)= P(X=0) +P(X=1)+P(X=2) +P(X=3)$

And we can find the individual probabilities like this:

$P(X=0) =1.4^0 \frac{e^{-1.4}}{0!}= 0.2466$

$P(X=1) =1.4^1 \frac{e^{-1.4}}{1!}= 0.3452$

$P(X=2) =1.4^2 \frac{e^{-1.4}}{2!}= 0.2417$

$P(X=3) =1.4^3 \frac{e^{-1.4}}{3!}= 0.1128$

And replacing we got:

$P(X\leq 3)= P(X=0) +P(X=1)+P(X=2) +P(X=3)=0.2466+ 0.3452+0.2417+0.1128=0.9463$

Step-by-step explanation:

Definitions and concepts

The Poisson process is useful when we want to analyze the probability of ocurrence of an event in a time specified. The probability distribution for a random variable X following the Poisson distribution is given by:

$P(X=x) =\lambda^x \frac{e^{-\lambda}}{x!}$

And the parameter $\lambda=1.4$ represent the average ocurrence rate per unit of time.

Solution to the problem

For this case the batch would be rejected if we found more than 3 defects, so then the probability of accept the batch would be given by:

$P(X\leq 3)= P(X=0) +P(X=1)+P(X=2) +P(X=3)$

And we can find the individual probabilities like this:

$P(X=0) =1.4^0 \frac{e^{-1.4}}{0!}= 0.2466$

$P(X=1) =1.4^1 \frac{e^{-1.4}}{1!}= 0.3452$

$P(X=2) =1.4^2 \frac{e^{-1.4}}{2!}= 0.2417$

$P(X=3) =1.4^3 \frac{e^{-1.4}}{3!}= 0.1128$

And replacing we got:

$P(X\leq 3)= P(X=0) +P(X=1)+P(X=2) +P(X=3)=0.2466+ 0.3452+0.2417+0.1128=0.9463$

Find the probability of drawing a 10, replacing it, and drawing an ace.

lions [1.4K]

Assuming that you're talking about a standard deck of 52 cards, there are 4 tens and 4 aces.

So, at the beginning, you have probability 4/52=1/13 to draw a ten.

You replace, and you have an identical probability to draw an ace (you still have 4 favourable cases over 52 total cases).

Multiply the two probabilities to find the answer:

$\dfrac{1}{13}\cdot\dfrac{1}{13}=\dfrac{1}{169}$
