Answer:
Yes, (x - 3) is a factor of P(x) and 3 is a zero or root of P(x)
Step-by-step explanation:
Determine whether or not (x - 3) is a factor by using synthetic division with +3 as the divisor. The coefficients of the polynomial p(x) are {2 -5 -4 0 9}.
Setting up synthetic division:
3 / 2 -5 -4 0 9
6 3 -3 -9
-------------------------------
2 1 -1 -3 0
Since the remainder is zero (0), we know that 3 is a root of the polynomial P(x) and that (x - 3) is a factor of said polynomial.
Biased estimators are Sample median & sample standard deviation
Unbiased are sample mean sample variance and sample proportion
Neither choice include population mean, standard deviation proportion and variance

➷ 1) (3(3) + 4.5) - |-5| = 8.5
2) (4(5) - (15)^2 = 25
3) (2)^3 - 6 - 4 = -2
4) 3(-10) - 5(6) = -60
5) 6 + 1/2(10 + 8) = 15
6) square root of (4 + (6 x 5)) = 5.830951895
