If all 25 questions are different,
When order of selection counts:
P(25,7)
=25!/(25-7)!
=15511210043330985984000000/6402373705728000
=2422728000
When order of selection does not count count:
C(25,7)
=25!/(7!*(25-7)!)
=15511210043330985984000000/(6402373705728000*5040)
=480700
Answer:
41,000
Step-by-step explanation:
If it is under 5 you round down. Hope this helps! Plz give brainliest!
"14,494 rounded to the nearest ten-thousands" would be 10,000.
Because the value of the digit before the ten thousands place (4) is less than the value of 5, the digit in the ten-thousands position does not change.
