Find the slope of the line.
S_A_V [24]
Given two points (x₁,y₁) and (x₂,y₂), the slope of the line passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)

In this case, the points are (-5,-4) and (1,-3) and the slope would be:
m=(-3+4)/(1+5)=1/6

Answer: the slope would be 1/6

On the basis of sample of 25 students in a large campus laboratory, it appears that 8 students smoke. A 95% CI estimate of the p
artcher [175]

Answer:

a. [0.137, 0.503]

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 interval 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:

A sample of 25 students in the lab, of whom 8 smoke. So n = 25, \pi = \frac{8}{25} = 0.32

95% confidence interval

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so z = 1.96.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.32 - 1.96\sqrt{\frac{0.32*0.68}{25}} = 0.137

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.32 + 1.96\sqrt{\frac{0.32*0.68}{25}}{119}} = 0.503

The correct answer is:

a. [0.137, 0.503]

lana66690 [7]

Set up a ratio:

1/50 = x/480

Cross multiply:

50x = 480

Divide both sides by 50:

X = 9.6

The distance on the map is 9.6 cm
