What is the measure of each angle of a regular 24-gon? If necessary, round to thenearest tenth.

Answers

Answer 1
Answer:

Answer:

165°

Step-by-step explanation:

Find the interior angle measure by using the formula, ((n - 2) x 180°) / n

Plug in 24 as n:

((n - 2) x 180°) / n

((24 - 2) x 180°) / 24

(22 x 180°) / 24

3960 / 24

= 165

So, the measure of each angle is 165°
Answer 2
Answer:

Answer:

163.6

Step-by-step explanation:

180•(22-2)=180•20 =3600

3600/22= 163.636363…

In Exercise 5.21, we learned that a Rasmussen Reports survey of 1,000 USadults found that 42% believe raising the minimum wage will help the economy. Construct a 99% confidence interval for the true proportion of US adults who believe this.

Can you show a pic of the question

Final answer:

The 99% confidence interval for the proportion of US adults believing that raising the minimum wage will help the economy, based on a survey, is approximately (0.386, 0.454).

Explanation:

To compute the 99% confidence interval for the parameter of interest - the true proportion of adults believing that raising the minimum wage will help the economy - we use the formula for the confidence interval for a proportion: p ± Z*(sqrt((p(1 - p))/n)). Here p is the sample proportion, n is the sample size and Z* is the Z score corresponding to the desired confidence level, in this case 99%.

The given sample proportion (p) is 0.42 and the sample size (n) is 1000. The Z score for a 99% confidence interval is approximately 2.58.

Substituting these values into the confidence interval formula yields: 0.42 ± 2.58 * sqrt((0.42(1 - 0.42))/1000). After computation, we obtain the 99% confidence interval as (0.386, 0.454).

An investigative bureau uses a laboratory method to match the lead in a bullet found at a crime scene with unexpended lead cartridges found in the possession of a suspect. The value of this evidence depends on the chance of a false positive positive that is the probability that the bureau finds a match given that the lead at the crime scene and the lead in the possession of the suspect are actually from two differant melts or sources. To estimate the false positive rate the bureau collected 1851 bullets that the agency was confident all came from differant melts. The using its established ctireria the bureau examined every possible pair of bullets and found 658 matches. Use this info to to compute the chance of a false positive.

Answers

Answer:

Step-by-step explanation:

Given that, we have 1851 bullets that we KNOW are NOT MATCHES of one another. One by one they examine two bullets at a time.

So, there are 1851 bullets but each time we choose 2.

We have, N choose K = N! / K! (N-k)!

Here, N = 1851 and K = 2

Therefore, 1851 choose 2 = 1851! / 2! (1851-2)!

                                         = 1851! / 2! * 1849!

                                         = 1712175 Possible Combinations

Out of these 653 are false positive.

The chance of getting false positive is = 658 / 1712175

                                                            = 0.000384

                                                           = 0.0384 %

Therefore, The correct option is

The chance of false positive is 0.0384% Because this probability is sufficiently small (< or = 1%) There is high confidence in the agency's forensic evidence.
