Answer:
551.181 this is the r swe
Step-by-step explanation:
The probability of drawing a purple piece during the first class is 7/25 because 7 pieces of paper are purple out of a total of 25 pieces of paper
Since all pieces of paper are returned, the probability of drawing a blue piece during the second class is 2/25 since there are 2 blue pieces out of a total of 25 pieces of paper
The wording is meant to trick you here. If the purple paper from the morning was not replaced before drawing the probability of drawing a blue piece in the second class would increase.
Always remember to reduce fractions where you can
X/8-1/2=6
X/8=6+1/2=13/2
X/8=52/8
X=52

Explanation:
a perpendicular bisector, bisects a line segment at
right angles
to obtain the equation we require slope and a point on it
find the midpoint and slope of the given points
