Answer:
Option (3)
Step-by-step explanation:
If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.
(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)
= -2x³ + x² + 9x + 12x² - 6x - 54
= -2x³ + 13x² + 3x - 54
Therefore, Option (3) will be the correct option.
Answer:
Mean: 49
Mode: none, since all the numbers only appear once
Median: 48
Range: 69
Step-by-step explanation:
53+64+19+25+88+48+46 = 343
343/7= 49 (mean)
19, 25, 26, 48, 53, 64, 88 (middle number is 48, so the median is 48)
Range= largest number-smallest number
88-19= 69 (range)
