The length of a rectangular garden is 6 feet less than 3 times its width. the area is 360 square feet. what is the length of the
aleksandr82 [10.1K]
l = 3w-6
\\A = l*w
\\A = (3w-6)(w)
\\360 = (3w-6)(w)
\\ 360 = 3w^2 - 6w
\\ 0 = 3w^2-6w-360
\\ 3(w^2-2w-120) = 0
\\ 3(w+10)(w-12) = 0
\\ w = 12 
\\ 12*3 = 36 -6 = 30
\\ l = 30

The poll found that 38% of a random sample of 1012 American adults said they believe in ghosts. What is the lower bound for a 90
Brrunno [24]

Answer:

The lower bound for a 90% confidence interval for the percentage of all American adults who believe in ghosts is 0.3549

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}.

For this problem, we have that:

n = 1012, \pi = 0.38

90% confidence level

So \alpha = 0.1, z is the value of Z that has a pvalue of 1 - \frac{0.1}{2} = 0.95, so Z = 1.645.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.38 - 1.645\sqrt{\frac{0.38*0.62}{1012}} = 0.3549

The lower bound for a 90% confidence interval for the percentage of all American adults who believe in ghosts is 0.3549
