There were 12,608 visitors to a museum in June. What is this number rounded to the nearest ten thousand? Complete the explanatio

Nina [5.8K]

Answer:

The rounded number is 10,000.

Step-by-step explanation:

Rounding means making a number simpler but keeping its value close to what it was.

The digit in the ten thousands place is 1.

The digit to its right is 2, so the digit in the ten thousands place stays the same.

Leave it the same if the next digit is less than 5, this is called rounding down. And increase it by 1 if the next digit is 5 or more, this is called rounding up

The number of years a radio functions is exponentially distributed with parameter λ = 1 8 . If Jones buys a used radio, what is

blsea [12.9K]

Answer:

$P(X>8)=e^{-1}$

Step-by-step explanation:

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:

$P(X=x)=\lambda e^{-\lambda x}, x>0$

And 0 for other case. Let X the random variable that represent "The number of years a radio functions" and we know that the distribution is given by:

$X \sim Exp(\lambda=\frac{1}{8})$

We can assume that the random variable t represent the number of years that the radio is already here. So the interest is find this probability:

$P(X>8|X>t)$

We have an important property on the exponential distribution called "Memoryless" property and says this:

$P(X>a+t| X>t)=P(X>a)$

Where a represent a shift and t the time of interest.

On this case then $P(X>8|X>t)=P(X>8+t|X>t)=P(X>8)$

We can use the definition of the density function and find this probability:

$P(X>8)=\int_{8}^{\infty} \frac{1}{8}e^{-\frac{1}{8}x}dx$

$=\frac{1}{8} \int_{8}^{\infty} e^{-\frac{1}{8}x}dx$

$=[lim_{x\to\infty} (-e^{-\frac{1}{8}x})+e^{-1}]=0+e^{-1}=e^{-1}$

No more asking me to click on links answer truthfully

Alborosie

Ok so the correct answers are both A. and B.

It would be A. between 1.5 and 2, because the number 1.77 is in between those two numbers. It is greater than 1.5 but also less than 2.

It would be B. to the right of 1.71, because the number 1.77 is greater than 1.71.

I hope this helps! Good luck on your homework!!
