Tony is writing a fraction equivalent to 2/7 using the formula 2*m/7*n. which statement about m and n must be true so that tony fraction has the same value as 2/7 a. m/n has to be greater than 1 b. m/n has to equal 7 c. m/n has to be greater than 2 d. m/n has to equal 1

the answer is A i think

                                                  hope it helps

Step-by-step explanation:

Given that Tony is writing a fraction equivalent to using the formula

Since this is equal to 2/7

we must have the value of

Hence option D is right.

step-by-step explanation:

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.
