Answer:

$P(x = 5) = 0.2441$

Step-by-step explanation:

Given

$p = 0.48$ --- proportion that have very little confidence

$n = 10$ --- sample

Required

Determine the probability that exactly 5 have very little confidence

This question will be solved using binomial probability:

$P(x) = ^nC_xp^x(1-p)^{n-x}$

In this case: x = 5.

So, we have:

$P(x = 5) = ^{10}C_5*0.48^5(1-0.48)^{10-5}$

$P(x = 5) = ^{10}C_5*0.48^5*0.52^5$

$P(x = 5) = 252*0.48^5*0.52^5$

$P(x = 5) = 0.2441$

5) Is 3 a zero (or root) of f(x) = x3 - 9x2 + 11x + 21?

frozen [14]

Answer:

Yes

Step-by-step explanation:

f(x) = x³ − 9x² + 11x + 21

f(3) = (3)³ − 9(3)² + 11(3) + 21

f(3) = 27 − 81 + 33 + 21

f(3) = 0
