a bag contains 3 red balls 3 green ball and 1 blue ball. a ball is chosen at random and then placed back in the bag. a second ball is chosen at random. Find the probability that :a) the first ball is red?

Circle a has center of (2,3) and a radius of 5 and circle b has a center of (1,4) and a radius of 10. what steps will show that circle a is similar to circle b 1) dilate circle a by a scale factor of 2 2) translate circle a using the rule (x+1,y-1) 3) rotate circle a 180 degrees about the center 4) reflect circle a over the y-axis
