I think this is wrong but square
Answer:
d = 
Step-by-step explanation:
The distance formula is d = 
Plug in the points.
d = 
Solve
d = 
Simplify by separating 18 into 9x2
d = 
Take the square root of 9 to finish simplifying
d = 
The interior angle measures are 900 degrees
131+122+125+148+107+126 = 759
900-759 =141
X = 141
P(boy) is asking for the probability that a boy will be chosen to read a poem out loud. Since there are 15 boys, we can get the probability by dividing this with the total number of students. This is because out of all the students, there is an equal possibility that each of the 15 boys will be chosen.
ANSWER: The probability that a boy is selected is 0.5357 or 53.57%
