Round 23,421 to the nearest thousand and ten thousand

23,421 to the nearest thousand  is 23,000

23,421 to the nearest ten thousand  is 20,000

Step-by-step explanation:

round 23,421 to the nearest thousand and ten thousand

1 is in once place

2 is in tens place

4 is in hundreds place

3 is in thousands place

2 is in ten thousands place

To round the given number to nearest thousand , we look at the number in hundreds place. 4 is in hundreds place that is less than 5.

23,421 to the nearest thousand  is 23,000

To round the given number to nearest ten thousand , we look at the number in thousands place. 3 is in thousands place that is less than 5.

23,421 to the nearest ten thousand  is 20,000

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
