Ends of a diameter: (-9, -16) and (3,0)
lbvjy [14]

Answer:

One example is the equation:

2x + 6 = 4x/2 + 12/2

To solve this, we need to transpose like terms to the same side.

2x - 4x/2 = 12/2 - 6

2x - 2x = 6 - 6

0 = 0

Since both sides are zero, it means that the equation has infinite number of solutions.

(Sec. 8.4) In a sample of 165 students at an Australian university that introduced the use of plagiarism-detection software in a
marusya05 [52]

Answer:

z=\frac{0.667 -0.5}{\sqrt{\frac{0.5(1-0.5)}{165}}}=4.29  

The p value for this case is given by:

p_v =P(z>4.29)=8.93x10^{-6}  

Since the p value is lower than the significance level we have enough evidence to conclude that the true proportion is significantly higher than 0.5 at 5% of significance.

Step-by-step explanation:

Information given

n=165 represent the random sample selected

55 represent the students indicated a belief that such software unfairly targets students

X =165-55= 110 represent students who NOT belief that such software unfairly targets students

\hat p=\frac{110}{165}=0.667 estimated proportion of  students who NOT belief that such software unfairly targets students

p_o=0.5 is the value that we want to check

\alpha=0.05 represent the significance level

z would represent the statistic

p_v represent the p value

System of hypothesis

We want to check if the majority of students at the university do not believe that it unfairly targets them, and the system of hypothesis are:

Null hypothesis:p\leq 0.5  

Alternative hypothesis:p > 0.5  

The statistic for this case is given by:

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

After replace we got:

z=\frac{0.667 -0.5}{\sqrt{\frac{0.5(1-0.5)}{165}}}=4.29  

The p value for this case is given by:

p_v =P(z>4.29)=8.93x10^{-6}  

Since the p value is lower than the significance level we have enough evidence to conclude that the true proportion is significantly higher than 0.5 at 5% of significance.
