△RST is shown below. XU = –2y + 15 and XW = 3y + 5. There is a triangle RST in which V, W and U are the points on the side RS, side ST and side RT respectively. Segment RX is the angle bisectors of angle TRS, segment SX is the angle bisectors of angle RST, and segment TX is the angle bisectors of angle STR. Segment RX, segment SX, and segment TX intersect each other at point X. Segment XV is perpendicular to side RS, segment XW is perpendicular to side ST, and segment XU is perpendicular to side RT. Find the measure of the radius of the inscribed circle of △RST. Enter your answer in the box.

answer: the equation matches the regression

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.

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
