Answer:

P(X

And we can find this probability using the normal standard table or excel:

P(Z

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the amount of ml of a population, and for this case we know the distribution for X is given by:

X \sim N(298,3)  

Where \mu=298 and \sigma=3

We are interested on this probability

P(X

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(X

And we can find this probability using the normal standard table or excel:

P(Z

In Angkor, Cambodia’s ancient city, a clever/A
stealth61 [152]

There is an error in clever.

<h3>What is the history of Angkor?</h3>

A dynasty of Khmer monarchs oversaw one of the biggest, wealthiest, and most advanced kingdoms in Southeast Asia's history from the city of Angkor, which served as the country's capital. The kings of Angkor ruled over a region that stretched from the tip of the Indochinese Peninsula northward to modern-day Yunnan province, China, and from Vietnam westward toward the Bay of Bengal from the last decade of the 9th century, when King Yashovarman I made Angkor his home, until the early years of the 13th century. These kings built a number of enormous structures throughout this time period to exalt themselves, their gods, and their capital city. They did this by using the enormous labour and financial resources at their disposal.

DochEvi [55]

Answer:

33×33+33-33÷0=infinity

33×33=1089

33-33=0

Taking L.H.S

=33×33+(33-33)÷0

=1089+0÷0

=1089÷0

=infinity

L.H.S=R.H.S
