is the number?
a. 2n = 3n − 12, 12 c. 2n = 12 − 3n, 2.4
b. 2n = 12 − 3n, 3 d. 2n = 12 − 3n, 2

Which statement best describes the polynomial

What is the quadric regression equation that fits these data

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
