Answer:
Step-by-step explanation:
prime factorization
40y³ = 2³×5y³
625 = 5⁴
Greatest common factor = 5
40y³ - 625 = 5(8y³ - 125)
Note that 8y³ - 125 is the difference of cubes.
8y³ - 125 = (2y)³ - 5³ = (2y-5)((2y)² + 2y·5 + 5²) = (2y-5)(4y² + 10y + 25)
40y³ - 625 = 5(2y-5)(4y² + 10y + 25)
Outliers are like outcasts of the group
Which number is farthest away from the average?
1-5 seems to be average
Solution: 25 is the outlier
1st find the averages of each one:
Elizabeth average of reading in min =(18+36+15+45+88+57+12)/7 =38.71 min
Sam average of reading in min =(17+52+48+35+13+71+16)/7 =36 min
question:
1) No
2) YES. [the range is te difference between the largest & the smallest)
Eliz Range = 88-12 =76 & Sam's= 71-13 = 58
3) NO. Sam 71 min & Eliz 88 min
4) YES. Median Eliz =45 min. Median Sam =35 min
Answer:
4 it would go back in order
