It is not always possible to measure every individual in a population; what is the name of the representative group
Scorpion4ik [409]

Answer:

Sample

Step-by-step explanation:

The term that represents the description in the question is called sample.

Take for instance:

  • 40 students selected from a class of 100
  • 1000 people selected from a population of 100000

In the above descriptions:

40 and 1000 represent the samples while 100 and 100000 represent the populations, respectively.

Another example is when 10 cats are picked from an animal farm in order to study their eating pattern.

All these and many more represent sample.

Use the ratio test to show that the series is convergent.<br><br> Thank you!
igor_vitrenko [27]

Step-by-step explanation:

lim(n→∞) |aₙ₊₁ / aₙ|

lim(n→∞) | (4ⁿ⁺¹ / (n+1)!) / (4ⁿ / n!) |

lim(n→∞) | (4ⁿ⁺¹ / (n+1)!) × (n! / 4ⁿ) |

lim(n→∞) | 4 / (n+1) |

0

Since the limit is less than 1, the series converges.

What’s the equivalent of 50000
dezoksy [38]

Is this for money? Do you want an equivalent fraction? Please be more specific, but I'll imply a couple of options.

FOR MONEY:

50,000 euros is 55142.50 dollars

50,000 dollars is 45337.08 euros

Is 50,000 US dollars a good salary? In my opinion, yes. If you are a single person, and you work an office job from 9 to 5, then yes, that is a good salary.

MATH/NUMBERS:

50,000 = 100,000 ÷ 2

50,000 = 200,000 ÷ 4

50,000 = 25,000 × 2

50,000 = 12,500 × 4

There are other examples that could be used for both money and math, but I would not be able/do not have the time to list them all.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I hope this helps!
