Which of the following represents the zeros of the function
umka21 [38]
<span>g(x) = x^3 - 9x^2 + 2x + 48 ?

Probe some roots. When you use x = - 2

you will have: (-2)^3 - 9(-2)^2 + 2(-2) + 48 = -8 - 36 - 4 + 48 = 0

So, - 2 is a root

From that you can divide x^3 - 9x^2 + 2x + 48 by x + 2 and you will get

x^2 - 11x + 24

Then you can factor that: (x - 8)(x - 3)

So, the three roots are x = - 2, x = 3 and x = 8, which is the option B.

Answer: option B. x = 8, x = -2 , and x = 3

(3 points) A survey of 15651565 people who took trips revealed that 178178 of them included a visit to a theme park. Based on th
igor_vitrenko [27]

Answer:

We fail to reject the null hypothesis at 0.05 significance level. We cannot say that less than 12% of trips include a theme park visit.  

Step-by-step explanation:

let p be the proportion of trips included a visit to a theme park.

H_{0}: p=0.12

H_{a}: p<0.12

To test, we need to calculate test statistic of the sample proportion as:

z=\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } } where

  • p(s) is the sample proportion of trips included visit to a theme park (\frac{178}{1565}=0.1137
  • p is the proportion assumed under null hypothesis. (0.12)
  • N is the sample size (1565)

Using the numbers, z=\frac{0.1137-0.12}{\sqrt{\frac{0.12*0.88}{1565}}}

= −0.767 and p(z) is ≈0.222

Since 0.222 > 0.05 we fail to reject the null hypothesis.
