When Ricki walks to school on the sidewalk, she walks 7/10 mile.
She then takes a shortcut across the field, which is 1/4 mile long.
How long is Ricki route to school?
PLS HELP HURRY I KNOW ITS LATE

Ricki's route to school is 19/20 miles long.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

So, to calculate the length of Ricki's route to school we have to simply add both lengths. (Sidewalk and shortcut)

Mathematically speaking:

7/10 + 1/4 = 14/20+ 5/20 = 19/20 miles

Ricki's route to school is 19/20 miles long.

Feel free to ask for more if needed or if you did not understand something.

step-by-step explanation:

their are no angles. sorry cant .

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.
