Enter the value of p so that the expression 3(4+n) is equivalent to 3(n+p)

For the value of p as 4, the given expression 3(4+n) will be equivalent to 3(n+p).

The given expression is .

It is required to find the value of p such that the given expression is equivalent to the expression .

Now, the given expression can be written as,

because addition follows commutative law.

Now, compare the given expressions to get the value of p as,

Therefore, for the value of p as 4, the given expressions 3(4+n) will be equivalent to 3(n+p).

4

Step-by-step explanation:

Since 3(4+n) is equivalent to 3(n+p), 4 would be the correct answer

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.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
