The future parents are wondering how many boys they might get if they have three children.
Give a probability model (sample space and probabilities of outcomes) for the number of boys.
What is the sample space?

Acircle has a circumference of 7.850 units. what is its radius?

Find the vertex for the parabola given by the function ƒ(x) = −3x2 − 6x.

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
