What is the slope of a line perpendicular to the with equation y=6x+2? A.6 B.-6 C.-1/6 D.2
zhuklara [117]
The equation y = 6x + 2 is in the format which is called the slope-intercept form: y = mx + b where m = slope. Therefore the slope here is 6.
For the line perpendicular, the slope of it is a negative reciprocal from the original slope, that is m(perpendicular) = -1/m

Slope the line perpendicular is m(perpendicular) = -1/6. The answer is C.

Katrina wants to estimate the proportion of adults who read at least 10 books last year. To do​ so, she obtains a simple random
kicyunya [14]

Answer:

D. Matthew's estimate will have the smaller margin of error because the larger sample size more than compensates for the higher level of confidence

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}.

The margin of error is the division by 2 of the upper level of the interval \pi + z\sqrt{\frac{\pi(1-\pi)}{n}} by the lower level \pi - z\sqrt{\frac{\pi(1-\pi)}{n}}, so this is

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

Both Katrina and Matthew are working with the same population, so \pi is equal for both.

Katrina

Katrina wants to estimate the proportion of adults who read at least 10 books last year. To do​ so, she obtains a simple random sample of 100 adults and constructs a​ 95% confidence interval. This means that she has z = 1.96 and n = 100. So her margin of error is

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

M = (1.96)\sqrt{\frac{\pi(1-\pi)}{100}}

M = 0.196\sqrt{\pi(1-\pi)}

Matthew

He obtains a simple random sample of 400 adults and constructs a​ 99% confidence interval.

This means that, for Matthew, z = 2.575, n = 400. So his margin of error is:

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

M = (2.575)\sqrt{\frac{\pi(1-\pi)}{20}}

M = 0.12875\sqrt{\pi(1-\pi)}

Higher confidence levels usually led to higher margins of error. However, Matthew's larger sample size compensates his higher confidence level.

So the correct answer is:

D. Matthew's estimate will have the smaller margin of error because the larger sample size more than compensates for the higher level of confidence
