Jack has written the name of each planet of the solar system on a separate piece of paper and has placed all these pieces of pap
Alinara [238K]

Answer:

<em>The probability that it would contain at least 6 letters is: </em><u><em>5/8</em></u>

<u><em></em></u>

Step-by-step explanation:

From the question given above,

We know that there are 8 planet that was given.

Mercury        7 letters

Venus           5 letters

Earth             5 letters

Mars              4 letters

Jupiter            7 letters

Saturn             6 letters

Uranus             6 letters

Neptune.          7 letters

Therefore,

P(at least 6 letters) + P( Less than 6 letters) = 1

P (at least 6 letters) + P (3 planet) = 1

P (at least 6 letters) +  ( 3/8) = 1

P(at least 6 letters) = 1 - (3/8)

= 5/8

How might a psychiatrist describe a paper plate?
spayn [35]

Answer:

A psychiatrist interprets the thing based on its physical appearance and sometimes in a way that is beyond everyone's imagination so in case of paper plate instead of thinking it as a plate used for eating or something, a psychiatrist may only go upon its physical properties that it is made up of paper and end up in describing it as a piece of paper.

So, A psychiatrist might describe a paper plate as a simple piece of paper.

The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airp
yKpoI14uk [10]

Answer:

Confidence Interval in 95% confidence level for the quality rating is (6.06,7.46)

Step-by-step explanation:

Confidence Interval can be calculated using the formula M±ME where

  • M is the mean of the sample
  • ME is the margin of error in a given confidence level

Using the sample obtained from 50 business travelers we get

  • Mean of the sample is 6.76
  • standard deviation of the sample is 2.526

Margin of error (ME) around the mean using the formula

ME=\frac{z*s}{\sqrt{N} } where

  • z is the corresponding statistic in 95% confidence level (1.96)
  • s is the standard deviation of the sample (2.526)
  • N is the sample size (50)

Using the numbers in the formula we get:

ME=\frac{1.96*2.526}{\sqrt{50} } ≈ 0.70

Then the confidence interval becomes 6.76±0.70
