1. The Sky Train from the terminal to the rental car and long-term parking center is supposed to arrive every 12 minutes. The waiting times for the train are known to follow a uniform distribution. What is the average waiting time (in minutes)?2. The Sky Train from the terminal to the rental car and long-term parking center is supposed to arrive every 16 minutes. The waiting times for the train are known to follow a uniform distribution. Find the 20th percentile for the waiting times (in minutes).3. The Sky Train from the terminal to the rental car and long-term parking center is supposed to arrive every 18 minutes. The waiting times for the train are known to follow a uniform distribution. What is the probability of waiting more than 16 minutes given a person has waited more than 9 minutes?
Answer:
a
[tex]\mu = 6[/tex]
b
[tex]x= 3.2[/tex]
c
[tex]P( X> 16 | X > 9 ) = 0.222[/tex]
Step-by-step explanation:
Considering question 1
From the question we are told that
The waiting times for the train are known to follow a uniform distribution
i.e
[tex]X \~ \ \ \ Uniform(a =0 , b= 12)[/tex]
Generally the cumulative distribution function for uniform distribution is mathematically represented as
[tex]F(x) = \left \{ {{0 \ \ \ \ \ \ \\ \ \ \ for x < a } \atop {\frac{x - a}{b-a} \ \ \ \ \ \ for a \le x \ le b }} \atop { 1 \ \ \ \ \ \ \ \ \ \ \ for x > b}\right. [/tex]
Generally the average time is mathematically represented as
[tex]\mu = \frac{a+ b}{2}[/tex]
=> [tex]\mu = \frac{0+ 12}{2}[/tex]
=> [tex]\mu = 6[/tex]
Considering question 2
The waiting times for the train are known to follow a uniform distribution
i.e
[tex]X \~ \ \ \ Uniform(a =0 , b= 16)[/tex]
Generally the 20th percentile of the waiting time is mathematically represented as
[tex]f(x) = \frac{x- a }{b- a} = 0.2[/tex]
=> [tex]f(x) = \frac{x- 0 }{16- 0} = 0.2[/tex]
=> [tex]x= 3.2[/tex]
Considering question 3
The waiting times for the train are known to follow a uniform distribution
i.e
[tex]X \~ \ \ \ Uniform(a =0 , b= 18)[/tex]
Generally the probability of waiting more than 16 minutes given a person has waited more than 9 minutes
[tex]P( X> 16 | X > 9 ) = \frac{P( X > 16 \ \ n \ \ X > 9 )}{P( X > 9 )}[/tex]
=> [tex]P( X> 16 | X > 9 ) = \frac{ P(X > 16 )}{P( X > 9 )}[/tex]
=> [tex]P( X> 16 | X > 9 ) = \frac{\frac{18 - 16}{18} }{\frac{18 - 9}{9 } }[/tex]
=> [tex]P( X> 16 | X > 9 ) = 0.222[/tex]
The probability shows that the average waiting time is 6 minutes.
How to solve the probability?The average time will be calculated thus:
= (a + b)/2
= (0 + 12)/2
= 12/2
= 6 minutes
The 20th percentile for the waiting times will be calculated thus:
f(x) = (x - 0)/(16 - 0) = 0.2
x = 0.2 × 16
x = 3.2
Therefore, the 20th percentile for the waiting times is 3.2 minutes.
The probability of waiting more than 16 minutes given a person has waited more than 9 minutes will be calculated thus:
= [(18 - 16)/18] / [(18 - 9)/9]
= 0.222

choose the highest HCF of 6xy^3 and 9x^2y
A.x^2y^3
B.3xy
C.54x^3y^4
D.18x^2y^3
Answer:
3xy.
Step-by-step explanation:
HCF of 6 and 9 = 3.
HCF of x and x^2 = x.
HCF of y^3 and y = y.
So that would be 3xy.

In a class of 40 students, 75% returned their permission slips for the school field trip. HowIn a class of 40 students, 75% returned their permission slips for the school field trip. How many students returned their permission slips
Answer:
30 students
Step-by-step explanation:
Given
[tex]Students = 40[/tex]
[tex]\% = 75\%[/tex] ---- percentage of those that returned their slips
Required
Determine the number of those that returned their slips
Represent the number with n
To calculate n, we simply multiply the number of students by the percentage of those that returned their slips
i.e.
[tex]n = 40 * 75\%[/tex]
Convert % to decimal
[tex]n = 40 * 0.75[/tex]
[tex]n = 30[/tex]
Hence, 30 students returned their slips

f(x) -> 2 as x -> -∞ and f(x) -> ∞ as x -> ∞
Step-by-step explanation:
f(x) -> 2 as x -> -∞ and f(x) -> ∞ as x -> ∞
*this is because the graph shows that the y value cannot pass by 2 as the x value constantly decreases and as x is increasing, there is just an arrow showing that the graph is constantly going up and therefore going to ∞
Miss Garcia an art teacher is buying supplies for her next unit on ceramics. Her 25th six graders are making mugs and jugs estimated each one will use about three force of a pound of clay.

Answer:
33 7/20
Step-by-step explanation:
First you multiply the number of students performing in the problem (25) to the fraction 3/4 as stated in the problem itself.
25 * 3/4 = 18 3/4
Then you use the answer from the previous step and add it by the expected amount of pound of clay (20)
18 3/4 + 20 = 38 3/4
As from the last step, we use that number and subtract it by the leftover clay (5 2/5)
38 3/4 - 5 2/5 = 33 7/20
Answer:
33 7/20

An SRS of size 20 is drawn from a population that has a normal distribution. The sample has a mean of 122.5 and a standard deviation of 8. Give the standard error of the mean:______
Answer:
The value is [tex]\sigma_{\= x} = 1.789[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 20
The sample mean is [tex]\= x = 122.5[/tex]
The standard deviation is [tex]s = 8[/tex]
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{\= x} = \frac{s}{\sqrt{n} }[/tex]
=> [tex]\sigma_{\= x} = \frac{8}{\sqrt{20 } }[/tex]
=> [tex]\sigma_{\= x} = 1.789[/tex]

1+n/7=3
A. Do the reciprocal of 1/7
B. Divide both sides by 7
C. Multiply both sides by 7 for the inverse
D. Subtract 1 on both sides for the inverse
Answer:
C.
Step-by-step explanation:
I'm assuming that the equation is (1+n) / 7 = 3, where 1+n is the numerator and 7 is the denominator.
In this case, to isolate for n, you have to multiply both sides by 7.
then you get 1+n = 3/7, and then you can get n = 3/7 - 1

If ABC is reflected across the y-axis, what are the coordinates of C?
Answer:
C
Step-by-step explanation:
The y axis is vertical so you only change the x value.
The coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have a triangle shown on the coordinate plane.
If ABC is reflected across the y-axis,
Then the coordinate of C
From the figure, the coordinate of C is(before reflection)
C = (6, 3)
The rule for transformation if reflected across the y-axis:
(x, y) → (-x, y)
(6, 3) → (-6, 3)
Thus, the coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.

Step-by-step explanation:
(1). (f(0) = 2) > (g(0) = - 4) (True)
(2). f( - 4) = 4( - 4 ) + 2 = - 14
g( - 4) = (5/2)(- 4) - 4 = = - 14
f( - 4) = g( - 4) (True)
(3). f(6) = 4(6) + 2 = 26
g(12) = (5/2)(12) - 4 = 26
f(6) = g(12) (True)
(4). g(2) = (5/2)(2) - 4 = 1
f(2) = 4(2) + 2 = 10
g(2) > f(2) (False)
