Solve each equation using the quadratic formula. Find the exact solution, then approximate the solution to the nearest hundredth
Mariana [72]

Answer:

n_1=2.72\\n_2=0.61


Step-by-step explanation:

 To solve this problem you  must apply the proccedure shown below:

1. You have that the quadratic formula is:

x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}

2. To solve the quadratic equation you must substitute the values. So, you have that:

a=3\\b=-10\\c=5

Then you have:

 x=\frac{-(-10)+/-\sqrt{(-10)^{2}-4(3)(5)}}{2(3)}

3. Therefore, you obtain the following result:

x_1=2.72\\x_2=0.61

Which type of lines match these equations (2/3)x =(5/3)y<br> 2x-5y=0
Allisa [31]
This equation is a linear equation. They form straight lines. In this case, the line goes through the origin of a cartesian plane. It can be rewritten as
y = 2/5x. 
The graph looks like this:

In 2009 a survey of Internet usage found that 79 percent of adults age 18 years and older in the United States use the Internet.
Alex777 [14]

Answer:

0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}

Option d.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

79 percent of adults age 18 years and older in the United States use the Internet.

This means that \pi = 0.79

98% confidence level

So \alpha = 0.02, z is the value of Z that has a pvalue of 1 - \frac{0.02}{2} = 0.99, so Z = 2.33.

Which of the following should be used to find the sample size (n) needed?

We have to find n for which M = 0.025

So the equation is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}

Option d.
