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]

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
Rachel rents three DVDs from Watchflicks and two DVDs from Bluechest. The probability that a DVD is faulty is 4% for Watchflicks and 5% for Bluechest. All DVD rentals being faulty or otherwise are independent of each other. Calculate the probability that exactly
Answer:
0.017
Step-by-step explanation:
The probability that exactly some number of DVDs are faulty is approximately 0.9884 or 98.84%.
To calculate the probability that exactly a certain number of DVDs are faulty, we need to use the binomial probability formula. The binomial probability formula is given by: [tex]P(X = k) = C(n, k) * p^k * q^{n-k}[/tex]
- P(X = k) is the probability of getting exactly k successes (in this case, exactly k faulty DVDs).
- C(n, k) is the number of combinations of n items taken k at a time, also known as the binomial coefficient. It is calculated as [tex]C(n, k) = n! / (k! * (n - k)!).[/tex]
- p is the probability of success (getting a faulty DVD from Watchflicks or Bluechest).
- q is the probability of failure (getting a non-faulty DVD), which is equal to 1 - p.
- n is the total number of trials (in this case, the total number of DVDs rented).
Let's calculate the probability that exactly "x" DVDs are faulty (where x can be 0, 1, 2, 3, or 4).
Probability of getting a faulty DVD from Watchflicks (p1) = 4%
= 0.04
Probability of getting a faulty DVD from Bluechest (p2) = 5%
= 0.05
Total number of DVDs rented from Watchflicks (n1) = 3
Total number of DVDs rented from Bluechest (n2) = 2
Total number of DVDs rented (n) = n1 + n2
= 3 + 2
= 5
Let's calculate the probabilities for each value of x:
1. Probability that exactly 0 DVDs are faulty (x = 0):
[tex]P(X = 0) = C(5, 0) * (0.04)^0 * (1 - 0.04)^5 \\= 1 * 1 * 0.961^5 \\\approx 0.8145[/tex]
2. Probability that exactly 1 DVD is faulty (x = 1):
[tex]P(X = 1) = C(5, 1) * (0.04)^1 * (1 - 0.04)^4 \\= 5 * 0.04 * 0.960^4 \\\approx 0.1641[/tex]
3. Probability that exactly 2 DVDs are faulty (x = 2):
[tex]P(X = 2) = C(5, 2) * (0.04)^2 * (1 - 0.04)^3 \\= 10 * 0.0016 * 0.941^3 \\\approx0.0084[/tex]
4. Probability that exactly 3 DVDs are faulty (x = 3):
[tex]P(X = 3) = C(5, 3) * (0.04)^3 * (1 - 0.04)^2 \\= 10 * 0.000064 * 0.922^2\\ \approx0.0014[/tex]
5. Probability that exactly 4 DVDs are faulty (x = 4):
[tex]P(X = 4) = C(5, 4) * (0.04)^4 * (1 - 0.04)^1 \\= 5 * 0.00000256 * 0.960 \\\approx 0.0000024[/tex]
Now, to find the probability that "exactly" (all DVDs being accounted for) a certain number of DVDs are faulty, we simply add up the individual probabilities: P(exactly 0 DVDs faulty) + P(exactly 1 DVD faulty) + P(exactly 2 DVDs faulty) + P(exactly 3 DVDs faulty) + P(exactly 4 DVDs faulty) ≈ 0.8145 + 0.1641 + 0.0084 + 0.0014 + 0.0000024
≈ 0.9884

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

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.

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)
