1. Describe the impromptu speech. What are its major features?

Fantom [35]

Answer: Down Below

Step-by-step explanation:

1. An impromptu speech, by definition, is the one that a speaker delivers without any prior preparation on the topic. Impromptu, itself, means “doing something without preparation”. In declamation contests, a random topic is fired at the speaker on the spot, and the speaker gets just a few seconds to think over the topic.

2. Lack of Gestures. The most common problem with public speakers is the statue like position, which they assume on the stage.

Lack of Energy.

No Rapport with Audience.

Use of Notes.

No Eye Contact.

Disrespect for Fellow Speakers.

Rushing with Words

3. Florida Strawberry Festival

The Florida Strawberry Festival is an 11-day community event celebrating the strawberry harvest of Eastern Hillsborough County. Each year, over 500,000 visitors enjoy the festival's headline entertainment, youth livestock shows, rides, exhibits of commerce and, of course, its strawberry shortcake.

4. Done without being planned, organised, or rehearsed.

5. What makes impromptu speech different from an extemporaneous speech?

The difference is in the delivery method: the impromptu speech is generated instantly and delivered immediately; whereas, the extemporaneous speech is delivered using just a few notes.

a sector of a circle has a central angle measure of 60°, and an area of 14 sq inches, what is the area of the entire circle

damaskus [11]

Answer:

The answer is below!!

Step-by-step explanation:

The formula used to find the area of a circlular sector - a pie-shaped part of a circle. ... π. 4. 2. ·. 86. 360. = 12.01. What the formulae are doing is taking the area of the whole ... So for example, if thecentral angle was 90°, then the sector would have an area equal to one ... r is the radius of the circleof which the sector is part.

Hope I Helped!!

Serhud [2]

Answer:

The test statistic for this test is: z = -2.60, option b.

Step-by-step explanation:

The test statistic is:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

H0: p = 0.50 vs HA : p≠0.50

This means that $\mu = 0.5, \sigma = \sqrt{0.5*0.5} = 0.5$

A random sample of 900 13- to 17-year-olds found that 411 had a computer in their room with Internet access.

This means that $n = 900, X = \frac{411}{900} = 0.4567$

Value of the test-statistic:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{0.4567 - 0.5}{\frac{0.5}{\sqrt{900}}}$

$z = -2.598$

The test statistic for this test is: z = -2.60, option b(should be).

A police checkpoint is set up on New Years Eve to catch drunk drivers. It is known that 8% of drivers on New Years Eve have a bl

Delicious77 [7]

Answer:

(a) Let the probability drivers are drunk = P(D) = 0.08

The probability that drivers in the area never drink and drive, but are simply bad drivers = P(B) = 0.32

The probability that drivers in the area never drink and drive, and are good drivers = P(G) = 0.60

Let S = event that the police stops the driver.

(b) The probability that a randomly selected driver will be stopped at the checkpoint is 0.2016.

(c) The probability that a driver who is stopped at the checkpoint is drunk is 0.337.

Step-by-step explanation:

We are given that 8% of drivers on New Years' Eve have a blood-alcohol level that is above the legal limit. It is also known that 32% of drivers in the area never drink and drive, but are simply bad drivers. The remaining 60% of drivers never drink and drive and are good drivers.

At this particular checkpoint, the police stop 85% of the drunk drivers, stop 38% of the bad drivers, and stop 2% of the good drivers.

(a) Let the probability drivers are drunk = P(D) = 0.08

The probability that drivers in the area never drink and drive, but are simply bad drivers = P(B) = 0.32

The probability that drivers in the area never drink and drive, and are good drivers = P(G) = 0.60

Let S = <u><em>event that the police stops the driver</em></u>

These are the four events stated in the question.

(b) So, the probability that the police stop the drunk drivers = P(S/D) = 0.85

The probability that the police stop the bad drivers = P(S/B) = 0.38

The probability that the police stop the good drivers = P(S/G) = 0.02

Now, the probability that a randomly selected driver will be stopped at the checkpoint is given by = P(S)

P(S) = P(D) $\times$ P(S/D) + P(B) $\times$ P(S/B) + P(G) $\times$ P(S/G)

= (0.08 $\times$ 0.85) + (0.32 $\times$ 0.38) + (0.60 $\times$ 0.02)

= 0.068 + 0.1216 + 0.012

= 0.2016

Hence, the probability that a randomly selected driver will be stopped at the checkpoint is 0.2016.

(c) Now, the probability that a driver who is stopped at the checkpoint is drunk is given by = P(D/S)

P(S/W) = $\frac{P(D) \times P(S/D)}{P(D) \times P(S/D)+P(B) \times P(S/B)+P(G) \times P(S/G)}$

= $\frac{0.08\times 0.85}{0.08\times 0.85+0.32\times 0.38+0.60\times 0.02}$

= $\frac{0.068}{0.2016}$ = 0.337

Hence, the probability that a driver who is stopped at the checkpoint is drunk is 0.337.
