Last year, mr. engle's total income was $52,000, while his total expenses were $53,800. use the expression i-e/12, where i represents total income and e represents total expenses, to find the average difference between his income and expenses each month. then explain its meaning.

The average difference in income and expenses each month is -150,

It shows every month the expenses is $ 150 more than income.

Step-by-step explanation:

Given formula of  average difference between his income and expenses each month,

    ( Suppose A )

Where,

I = total income,

E = total expenses,

We have, I = $ 52,000, E = $ 53,800,

Thus, by substituting the values,

The average difference in income and expenses each month,

Negative sign shows that the expenses exceed the income every month.

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.
