worth 20 pts match each polynomial with its factorization. ***match the letters to the numbers*** ex. 3 is b ( for example only) 1. y^2 - y - 2 2. 3y^2 - 27 3. y^4 - 16 4. y^2 - 12y + 36 5. -4y^2 + 8y + 32 6. 5y - 2 + 4y^2 - 4 a. (y - 2)(y + 2)(y^2 + 4) b. -4(y + 2)( y - 4) c. (4y - 3)(y + 2) d. 3(y - 3)(y + 3) f. (y - 6)^2 g. (y + 1)(y - 2)

Fran would like to estimate the mean amount of time it takes people in her town to travel to work. the town's population is 150,000 and about 90,000 of those are working adults. which statements are true? select each correct answer. there is no way to infer the value of the mean. she must collect data for all 90,000 working adults and calculate the mean. a larger sample of working adults will provide a better estimate of the true mean than a smaller sample. the population of working adults is too large for using a sample to estimate the mean of the entire group. if she takes a random sample of the population of working adults in her town, the mean for that group is likely close to the mean for the entire group.

The volume of the sun is approximately 1 × 10^18 cu km, while the volume of jupiter is approximately 1 × 10^15 cu km. which of the following is true? a. the volume of jupiter is approximately one thousand times the volume of the sun. b. the volume of jupiter is approximately one hundred times the volume of the sun. c. the volume of the sun is approximately one thousand times the volume of jupiter. d. the volume of the sun is approximately one hundred times the volume of jupiter.
