Answer with explanation:

Given a Polynomial Function, it has following kind of Zeroes

1. Real Zeroes= Rational Zeroes + Irrational Zeroes, It can be shown on the xy  or Coordinate plane.For, example : 2, -5, 2.3, √2,∛5,π, etc.

2. Non Real Zeroes = Complex Zeroes or Imaginary Zeroes. It can not be shown on the x y  or Coordinate plane.

For, example: -2 i, 6 i,...

⇒⇒Zeros of a polynomial function that cannot be shown on the coordinate plane are called Complex or Imaginary zeros.

The first term of a sequence is -12. The recursive formula for the sequence is an = an-1 + 9. What are the next 3 terms in the s
gtnhenbr [62]
Hello :
by : <span>an = an-1 + 9. 
n= 2 : a2 =a1+9
         a2 = -12+9 = -3
n=3 : a3 = a2 +9 
        a3 = -3+9 = 6
n = 4 : a4 = a3 +9
           a4 =6+9 = 15</span>

You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly different from 0.36. With
Dafna11 [192]

Answer:

We need to conduct a hypothesis in order to test the claim that the true proportion is 0.36 so then we need to conduct a two tailed test, the system of hypothesis are.:  

Null hypothesis:p=0.36  

Alternative hypothesis:p \neq 0.36  

Since is a bilateral test the p value would be:  

p_v =2*P(z>2.074)=0.0381  

Step-by-step explanation:

Data given and notation n  

n represent the random sample taken

\hat p estimated proportion of interest

p_o=0.36 is the value that we want to test

z would represent the statistic (variable of interest)

p_v represent the p value (variable of interest)  

Concepts and formulas to use  

We need to conduct a hypothesis in order to test the claim that the true proportion is 0.36 so then we need to conduct a two tailed test, the system of hypothesis are.:  

Null hypothesis:p=0.36  

Alternative hypothesis:p \neq 0.36  

When we conduct a proportion test we need to use the z statisitc, and the is given by:  

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

The One-Sample Proportion Test is used to assess whether a population proportion  is significantly different from a hypothesized value .

Calculate the statistic  

For this case the statistic is given:

z = 2.074

Statistical decision  

It's important to refresh the p value method or p value approach . "This method is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.

The next step would be calculate the p value for this test.  

Since is a bilateral test the p value would be:  

p_v =2*P(z>2.074)=0.0381
