According to the triangle inequity if 20 and 25 are the lengths of two sides of a triangle then an inequality that represents all possible lengths for the third side is A. 0

B. 0

C. 5_

D. 5

Answer and explanation:

The inequality theorem states that the sum of the length of two sides of a triangle is greater than the third side of a triangle.

Also the difference of two sides of a triangle is less than the third side

If we apply this theorem here,

Then we say the third side x<20+25 and x>25-20

Therefore x<45 but >5

5<x<45

Possible sides of x include: 6,7,8,9,10,11,12,13,14,15,16,17,18...not equal to 45 or more than

step-by-step explanation:

goog be able to you with that maybe

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.
