Given a Poisson distribution with 0.05 flaws/sq ft and 10 sq ft panels, each car has a 60.65% chance of no flaws.
The probability of at least 1 car with flaws is 99.35%.
Considering only 1 car with flaws, the final probability of at most 1 car with flaws is 90.2%.
Probability of at most 1 car with flaws: 90.2%
Here's how to calculate the probability that at most 1 car out of 10 has any surface flaws, given the Poisson distribution parameters:
1. Define parameters:
Mean flaws per square foot (λ) = 0.05
Area of plastic panel per car (A) = 10 square feet
Number of cars (N) = 10
2. Calculate probability of no flaws:
Probability of no flaws in one car (P(X=0)) = e^(-λA) = e^(-0.0510) ≈ 0.6065
3. Calculate probability of 1 car with flaws (complementary probability):
Probability of at least 1 car with flaws (1 - P(no flaws in all cars))
P(X ≥ 1) = 1 - (P(X=0))^N = 1 - (0.6065)^10 ≈ 0.9935
Probability of exactly 1 car with flaws (P(X=1)) = N * P(X=0) * (1-P(X=0))^N-1
≈ 10 * 0.6065 * (1 - 0.6065)^9 ≈ 0.3869
4. Final probability:
Probability of at most 1 car with flaws (P(X ≤ 1)) = P(X=0) + P(X=1) ≈ 0.6065 + 0.3869 ≈ 0.9934
The probability that at most 1 car out of 10 has any surface flaws is approximately 90.2%.
Therefore, Given a Poisson distribution with 0.05 flaws/sq ft and 10 sq ft panels, each car has a 60.65% chance of no flaws.
The probability of at least 1 car with flaws is 99.35%.
Considering only 1 car with flaws, the final probability of at most 1 car with flaws is 90.2%.
The probable question may be: The number of surface flaws in plastic panels used in the interior of automobile has a Poisson distribution with a man of 0.05 flaws per square foot of plastic panel. Assume an automobile interior contains 10 square feet of plastic panel. If 10 cars are sold to a rental company, what is the probability that at most 1 car has any surface flaws?
a. The probability of no surface flaws in an auto's interior is approximately 0.7408.
b. The probability of none of the 10 cars having any surface flaws is approximately 0.0498.
c. The probability of at most 1 car having any surface flaws is approximately 0.9631.
a. Probability of no surface flaws:
Calculate the lambda parameter: The lambda parameter for the Poisson distribution represents the expected number of flaws, which is calculated as the mean flaws per square foot multiplied by the total area.
In this case, [tex]\lambda[/tex] = 0.03 flaws/sq ft * 10 sq ft = 0.3 flaws.
Use the Poisson probability formula: The probability of no flaws (x = 0) in a Poisson distribution is given by [tex]e^{(-\lambda)[/tex].
Plugging in lambda = 0.3, we get
P(x = 0) = [tex]e^{(-0.3)[/tex] ≈ 0.7408.
b. Probability of none of the 10 cars having flaws:
Treat each car as an independent event: Since the flaws are random and independent for each car, we can treat each car as a separate event with the same probability of no flaws (0.7408) calculated in part (a).
Calculate the combined probability: To get the probability of none of the 10 cars having flaws, we simply multiply the individual probabilities.
P(no flaws in all 10 cars) = [tex](0.7408)^{10[/tex] ≈ 0.0498.
c. Probability of at most 1 car having flaws:
Calculate probabilities for 0 and 1 flaws: We need the probabilities of 0 flaws (already calculated in part (a)) and 1 flaw (x = 1) to determine the probability of at most 1 flaw.
Probability of 1 flaw: Using the Poisson formula again,
P(x = 1) = [tex]\lambda[/tex] * [tex]e^{(-\lambda)[/tex] = 0.3 * [tex]e^{(-0.3)[/tex] ≈ 0.2222.
Probability of at most 1 flaw: This includes both scenarios with 0 and 1 flaws. P(at most 1 flaw) = P(0 flaws) + P(1 flaw) = 0.7408 + 0.2222 ≈ 0.9631.

Find the x-intercepts of the parabola with vertex (-3,-18) and y-intercept at (0,0)
To find the x-intercepts of the parabola given its vertex and y-intercept, we can first determine the equation of the parabola. Then, we set y equal to zero and solve for x. In this case, the x-intercepts are 0 and -6.
Explanation:The x-intercepts of a parabola can be found by setting the y-coordinate to zero and solving for x. The vertex form of a parabola is given by y = a(x - h)^2 + k, where (h, k) is the vertex. In this case, the vertex is (-3, -18), so the equation of the parabola is y = a(x + 3)^2 - 18. Since the y-intercept is at (0, 0), we can substitute these values into the equation to solve for a. Plugging in the values gives: 0 = a(0 + 3)^2 - 18. Solving for a, we get a = 2. Therefore, the equation of the parabola is y = 2(x + 3)^2 - 18. To find the x-intercepts, we set y equal to zero and solve for x: 0 = 2(x + 3)^2 - 18. Simplifying, we have 2(x + 3)^2 = 18. Dividing both sides by 2 gives (x + 3)^2 = 9. Taking the square root of both sides, we get x + 3 = ±3. Solving for x gives the x-intercepts as x = 0 and x = -6.

A scientist is working with 0.9m of gold wire. How long is the wire in millimeters?
Answer:
The length of the wire in millimeters is 9 × 10² mm.
Step-by-step explanation:
1 meter is equal to 1000 millimeters. This is the ratio that we use to convert a length in meters to one in millimeters. A scientist is working with 0.9 m of gold wire. We will use a conversion fraction to express this number in millimeters.
0.9 m × (1000 mm/ 1 m) = 900 mm = 9 × 10² mm (we round off to 1 significant figure)
The length of the wire in millimeters is 9 × 10² mm.

A theater can seat 144 people. The number of rows is 7 less than the number of seats in each row. How many rows of seats are there?
To determine the number of rows in the theater, we use the given information to create the equation x * (x - 7) = 144 where x is the number of seats per row. Factoring out, we find 16 and 9 as a suitable pair, leading to the conclusion that there are 9 rows of seats in the theater.
Explanation:The student's question involves finding the number of rows of seats in a theater given certain constraints. To solve this problem, let's designate x as the number of seats in each row. According to the question, the number of rows of seats is 7 less than the number of seats in a row, which can be written as x - 7. Since we know the theater can seat 144 people in total, we can create the following equation to represent the total number of seats:
x imes (x - 7) = 144
Solving this quadratic equation by factoring will give us the value of x, which will then allow us to calculate x - 7 for the number of rows. By factoring 144, we find that 16 and 9 are factors that satisfy the equation (16 imes 9 = 144) and also meet the condition that one factor is 7 less than the other (16 - 7 = 9). Therefore, the number of seats in each row is 16, and the number of rows is 16 - 7 which gives us 9 rows in the theater.

Janelle bought a pair of sneakers for $75.65. There was a 15% discount. What was the original price of the sneakers?
To determine the original price of Janelle's sneakers, we calculate the inverse of the 15% discount that left her with a final price of $75.65, revealing the original price to be $89.00.
To find the original price of the sneakers that Janelle bought with a 15% discount, we need to understand that the final price after the discount represents 85% of the original price. This is because a 15% discount reduces the original price by 15%, leaving us with 100% - 15% = 85% of the original price. Janelle's sneakers cost her $75.65 after the discount.
Let's denote the original price by x. Therefore, 85% of x is equal to $75.65. We can set up an equation to represent this relationship:
0.85x = $75.65
To find x, we divide both sides of the equation by 0.85:
X = $75.65 / 0.85
x = $89.00
Thus, the original price of the sneakers was $89.00 before the 15% discount.
