The mean hourly pay of an American Airlines flight attendant is normally distributed with a mean of $29.81 per hour and a standard deviation of $9.31 per hour. What is the probability that the hourly pay of a randomly selected flight attendant:
a. Is between the mean and $35.00 per hour? (Round intermediate calculations to 2 decimal places and final answer to 4 decimal places.)
b. Is more than $35.00 per hour? (Round intermediate calculations to 2 decimal places and final answer to 4 decimal places.)
c. Is less than $20.00 per hour? (Round intermediate calculations to 2 decimal places and final answer to 4 decimal places.)
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]

Q: Find the area!
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.

use a ciommon denominator to write an equivalent fraction for each fraction
A common denominator, which means having the same number in the denominator (or the bottom) of each fraction, creates equivalent fractions that can be added, subtracted, or compared. Finding a common denominator means finding one number that each denominator can divide into easily.

Piper used 1/3yard of ribbon to create a border around a
triangle. If the sides of the triangle are all the same length, how much ribbon did she use for each side
Answer:
1/9 yards of ribbon
Step-by-step explanation:
triangle = 3 sides
since it has the same length sides, then
(1/3) / 3 = 1/9 yards, or
1/3 feet, or
0.1111111... yards, or
0.3333333... feet, or

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]

Solve x2 - 16 = 59. What does x
equal?
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

A turntable has a diameter of 40 cm what its circumference
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
point k lies at (-3,4) Image
Answer:
[tex]k(x,y) --> k'(x,y-7)[/tex]
Step-by-step explanation:
Given
[tex]k = (-3,4)[/tex]
Translation: 7 units down
Required
Determine the rule to produce k'
When an (x,y) coordinate is translated down by h units, the resulting point is:
(x,y) --> (x, y - h)
In this case:
[tex]h = 7[/tex]
So, we have:
[tex]k(x,y) --> k'(x,y-7)[/tex]
Hence, option A answers the question.
Solving further to determine the coordinates of k'.
[tex]k = (-3,4)[/tex]
[tex]k' = (-3,4-7)[/tex]
[tex]k' = (-3,-3)[/tex]
