Answer:

a

 i. Proportion

b

 Best point estimate is   [tex]\^ p = 0.60[/tex]

c

   [tex]z_{\frac{\alpha }{2} } =  2.58 [/tex]

d

   [tex]E =  0.0206 [/tex]

e

   [tex] 0.5794 <  p < 0.6206 [/tex]    

Step-by-step explanation:

From the question we are told that

   The sample size is  n = 3765

   The  proportion that feel the businesses in Laradise, are run by compliant individuals  is  [tex]\^ p = 0.60[/tex]

Considering question a

   The correct option is  Proportion  because in the prompt we are told to obtain the fraction of the total sample size that has a particular attribute (which their opinion of business in Laradise) and this is what a proportion represents

Considering question b

  The best point estimate is   [tex]\^ p = 0.60[/tex] because this proportion best defines the fraction of the sample size who feel the businesses in Laradise, are run by compliant individuals

Considering question c

  Generally given that the sample size is large enough n > 30 , it then means that the distribution is approximately normal  so  

From the question we are told the confidence level is  99% , hence the level of significance is    

      [tex]\alpha = (100 - 99 ) \%[/tex]

=>   [tex]\alpha = 0.01[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]z_{\frac{\alpha }{2} } =  2.58 [/tex]

Considering question d

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]

=>  [tex]E =  2.58 * \sqrt{\frac{ 0.60  (1- 0.60 )}{ 3765} } [/tex]

=>  [tex]E =  0.0206 [/tex]      

Considering question e

Generally 99% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>   [tex] 0.60  -0.0206 <  p < 0.60  + 0.0206[/tex]    

=>   [tex] 0.5794 <  p < 0.6206 [/tex]

Answer:

Arranging the terms from least to greatest:

[tex]\frac{3039}{1000}<\frac{3200}{1000}<\frac{3990}{1000}<\frac{8200}{1000}[/tex]

Now actual terms arranged from least to greatest will be:

[tex]3\frac{39}{1000}<3\frac{1}{5} <3\frac{99}{100}<3\frac{52}{10}[/tex]

Step-by-step explanation:

We need to arrange the weights [tex]3\frac{1}{5} ,3\frac{39}{1000},3\frac{99}{100},3\frac{52}{10}[/tex] from least to greatest.

To arrange them in least to greatest we need to convert them into improper fractions and then make their denominators same.

[tex]3\frac{1}{5}=\frac{16}{5} \\3\frac{39}{1000}=\frac{3039}{1000} \\3\frac{99}{100}=\frac{399}{100} \\3\frac{52}{10}=\frac{82}{10}[/tex]

Now, Making their denominator same by taking LCM of 5,1000,100 and 10

The LCM is 1000

Now the fractions will become:

[tex]\frac{16}{5}=\frac{16*200}{5*200}=\frac{3200}{1000}[/tex]

[tex]\frac{399}{100}=\frac{399*10}{100*10}=\frac{3990}{1000}[/tex]

[tex]\frac{82}{10}=\frac{82*100}{10*100}=\frac{8200}{1000}[/tex]

Now we have fractions: [tex]\frac{3200}{1000},\frac{3990}{1000},\frac{8200}{1000},\frac{3039}{1000}[/tex]

Now the smallest term will be one having smallest numerator

Arranging the terms from least to greatest:

[tex]\frac{3039}{1000}<\frac{3200}{1000}<\frac{3990}{1000}<\frac{8200}{1000}[/tex]

Now actual terms arranged from least to greatest will be:

[tex]3\frac{39}{1000}<3\frac{1}{5} <3\frac{99}{100}<3\frac{52}{10}[/tex]

Answer:

37.5

Step-by-step explanation:

Answer:  x = 75/2 = 37.5

Step by Step:

Solve for x:

2 x - 16 = 59

Hint: | Isolate terms with x to the left hand side.

Add 16 to both sides:

2 x + (16 - 16) = 16 + 59

Hint: | Look for the difference of two identical terms.

16 - 16 = 0:

2 x = 59 + 16

Hint: | Evaluate 59 + 16.

59 + 16 = 75:

2 x = 75

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 75 by 2:

(2 x)/2 = 75/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

Answer:  x = 75/2 = 37.5

Answer:

Circumference of turntable is 125.6 cm

Step-by-step explanation:

Diameter of turntable = 40 cm

We need to find circumference of turntable.

The formula used to calculate circumference is: [tex]Circumference=2\pi r[/tex]

where r is radius

We know that: [tex]radius=\frac{diameter}{2}[/tex]

Finding radius first:

[tex]radius=\frac{diameter}{2}\\radius=\frac{40}{2}\\radius = 20 \ cm[/tex]

So, radius r=20 cm

Now finding circumference

[tex]Circumference=2\pi r\\Circumference=2\times3.14\times20\\Circumference=125.6 \ cm[/tex]

So, circumference of turntable is 125.6 cm

bc it’s right lolz

Answer:

a

[tex]P(29.81 < X < 35) = 0.21141[/tex]

b

[tex]P( X > 35) =0.28859[/tex]

c

 [tex]P( X < 20) =0.14601[/tex]    

Step-by-step explanation:

From the question we are told that

    The mean is  [tex]\mu = \$29.81[/tex]

    The standard deviation is [tex]\sigma = \$9.31[/tex]

Generally the probability that the hourly pay of a randomly selected flight attendant  Is between the mean and $35.00 per hour is mathematically represented as

      [tex]P(29.81 < X < 35) = P( \frac{ 29.81 - 29.81 }{9.31} < \frac{x - \mu }{\sigma} < \frac{ 35 - 29.81 }{9.31} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P(29.81 < X < 35) = P( 0 < Z < 0.5575 )[/tex]

=>   [tex]P(29.81 < X < 35) = P( Z < 0.5575) - P( Z < 0)[/tex]

From the z table  the area under the normal curve to the left corresponding to  0 and  0.5575   is  

   [tex]P( Z < 0) =0.5[/tex]

and

   [tex]P( Z < 0.5575) = 0.71141[/tex]

=>   [tex]P(29.81 < X < 35) = 0.71141 - 0.5[/tex]

=>   [tex]P(29.81 < X < 35) = 0.21141[/tex]

Generally the probability that the hourly pay of a randomly selected flight attendant  Is more than $35.00 per hour is mathematically represented as

   [tex]P(X > 35) = P( \frac{x - \mu }{\sigma} > \frac{ 35 - 29.81 }{9.31} )[/tex]

   [tex]P( X > 35) = P( Z > 0.5575 )[/tex]

From the z table  the area under the normal curve to the right  corresponding to 0.5575   is  

    [tex]P( Z > 0.5575 ) = 0.28859[/tex]

=>  [tex]P( X > 35) =0.28859[/tex]

Generally the probability that the hourly pay of a randomly selected flight attendant Is less than $20.00 per hour is mathematically represented as

   [tex]P(X <20 ) = P( \frac{x - \mu }{\sigma} < \frac{20 - 29.81 }{9.31} )[/tex]

   [tex]P( X < 20) = P( Z < -1.0537 )[/tex]

From the z table  the area under the normal curve to the right  corresponding to -1.0537  is  

    [tex]P( Z < -1.0537 ) = 0.14601[/tex]

=>  [tex]P( X < 20) =0.14601[/tex]

Step-by-step explanation:

Answer:

113.04 in^2

Step-by-step explanation:

A=pi*r^2

A=3.14*6^2

A=3.14*36

A=113.04

Answer

The area of the circle is [tex]36\pi[/tex] inches squared.

Explanation

The formula for the area of a circle is [tex]\pi r^{2}[/tex]. You are already given the radius (which is 6) so all you have to do is substitute the 6 for 'r' and solve the equation.

After substituting 6 for 'r' you get [tex]\pi 6^{2}[/tex].

According to PEMDAS, you have to solve 6 to the power of 2 first. 6 to the power of 2 is 36.

So the area of the circle is [tex]36\pi[/tex] inches squared.

If you would like to completely solve for the area, you can multiply 36 by 3.14. 36 times 3.14 equals 113.04. Note that this is not the exact answer, because [tex]\pi[/tex] is a never ending number, meaning if you multiplied both numbers, you product would also be a never ending number.

So the area of the circle is [tex]36\pi[/tex] or about [tex]113.04[/tex] inches squared.
