If melanie spins this spinner 1000 times, approximately how many times will it land on blue?

a. 500
b. 50
c. 667
d. 250

it would be 500

Step-by-step explanation:

since blue is covering 50% of the circle than the probability of it landing on blue is 50% and 50% of 1000 is 500

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
