Therefore, the frame length that gives a probability of 0.1 of one landing during any given frame is about 8.61 seconds.
Since we know the average rate of arrivals, we can use the Poisson distribution to model the number of landings per minute. Let λ be the average number of arrivals per minute, then the Poisson distribution with parameter λ is given by:
P(X = k) = (e^(-λ) * λ^k) / k!
where X is the number of arrivals in a given minute.
In this case, λ = 2. We want to find the frame length that gives a probability of 0.1 of one landing during any given frame. Let T be the frame length in minutes, then the number of arrivals during a frame follows a Poisson distribution with parameter λ*T.
We want to find T such that P(X = 1) = 0.1, where X is the number of arrivals during a frame. Substituting λ*T = 2T, we have:
P(X = 1) = (e^(-2T) * (2T)^1) / 1! = 2Te^(-2T)
Setting this equal to 0.1 and solving for T, we have:
2Te^(-2T) = 0.1
e^(-2T) = 0.05/T
Taking the natural logarithm of both sides, we have:
-2T = ln(0.05/T)
Multiplying both sides by -1/2, we have:
T = -ln(0.05/T) / 2
Using a numerical solver or a graphing calculator, we can find that T ≈ 0.1435 minutes, or about 8.61 seconds.

The radius r of a sphere is increasing at the uniform rate of 0.3 inches per second. At the instant when the surface area S becomes 100pi square inches, what is the rate of increase, in cubic inches per second, in the volume V?
The rate of increase in the volume V is 30π cubic inches per second when the surface area S becomes 100π square inches.
What is volume?
Volume refers to the amount of three-dimensional space occupied by an object or a substance.
To find the rate of increase in the volume V of a sphere when the surface area S becomes 100π square inches, we need to use the formulas relating the surface area and volume of a sphere to its radius.
The surface area S of a sphere is given by the formula:
[tex]S = 4\pi r^2,[/tex]
where r is the radius of the sphere.
The volume V of a sphere is given by the formula:
[tex]V = (4/3)\pi r^3.[/tex]
To find the rate of increase in volume with respect to time, we need to differentiate the volume formula with respect to time.
Given that the radius r is increasing at a uniform rate of 0.3 inches per second, we can write:
dr/dt = 0.3 inches per second.
Now, let's differentiate the volume formula with respect to time:
[tex]dV/dt = d/dt [(4/3)\pi r^3].[/tex]
Using the power rule of differentiation, we get:
[tex]dV/dt = (4/3)\pi * 3r^2 * (dr/dt).[/tex]
Simplifying further, we have:
[tex]dV/dt = 4\pi r^2 * (dr/dt).[/tex]
Since we want to find the rate of increase in cubic inches per second, we need to express the volume in cubic inches.
Substituting the value of the surface area S = 100π square inches into the surface area formula:
[tex]100\pi = 4\pi r^2.[/tex]
Dividing both sides by 4π, we get:
[tex]r^2 = 25.[/tex]
Taking the square root of both sides, we find:
r = 5.
Now, we can substitute the value of r into the rate of increase formula:
[tex]dV/dt = 4\pi(5^2) * (0.3).[/tex]
Simplifying the expression:
dV/dt = 4π(25) * 0.3.
dV/dt = 30π cubic inches per second.
Therefore, the rate of increase in the volume V is 30π cubic inches per second when the surface area S becomes 100π square inches.

Kyle is tossing bean bags at a target. So far, he has had 22 hits and 14 misses. What is the experimental probability that Kyle's next toss will be a hit?
The experimental probability that Kyle's next toss will be a hit is 11/18 or approximately 0.61.
The experimental probability of Kyle's next toss being a hit can be calculated by dividing the number of hits by the total number of tosses. In this case, the total number of tosses is the sum of hits and misses, which is 22 + 14 = 36. Therefore, the experimental probability of Kyle's next toss being a hit is 11/18 or approximately 0.61.
To find the experimental probability of Kyle's next toss being a hit, you need to consider the number of hits and total tosses so far.
Hits: 22
Misses: 14
Total tosses: 22 hits + 14 misses = 36 tosses
Now, calculate the experimental probability by dividing the number of hits by the total number of tosses:
Experimental probability = Hits / Total tosses = 22 / 36
Simplify the fraction:
Experimental probability = 11/18
So, the experimental probability that Kyle's next toss will be a hit is 11/18.

It’s a GCD(greatest common divisor) problem
The answers are 6 and $151
Answer: How Much Does the Farmer Get From the Sale of 10 Baskets?
Step-by-step explanation: If the greatest common divisor of 78 artichokes and 90 courgettes is 6, then the farmer can form at most 6 baskets with the same number of artichokes and courgettes. Therefore, the answer is $6.
If each artichoke is sold for €0.70 and each courgette is sold for €0.40, then the revenue from one basket is (0.70 * 6) + (0.40 * 6) = €6.60. The revenue from 10 baskets is 10 * €6.60 = €66.
Converting this to USD at the current exchange rate of 1 EUR = 1.18 USD, the revenue from 10 baskets is approximately $78.

if a random sample of size n is taken from a population, then sample mean is approximately normally distributed, if group of answer choices n is at least 30. the population is normally distributed. the population distribution is known. the random sample is unbiased. the random sample is stratified.
The sample mean is approximately normally distributed when a random sample of size n is taken from a population, provided that n is at least 30. This is known as the Central Limit Theorem. It states that as the sample size increases, the distribution of the sample mean approaches a normal distribution, regardless of the population's distribution.
If a random sample of size n is taken from a population, then the sample mean is approximately normally distributed, if the sample size n is at least 30. However, this assumption is valid only when the population is normally distributed, and the population distribution is known. Additionally, it is assumed that the random sample is unbiased, meaning that every member of the population has an equal chance of being selected. If the population is not normally distributed, the sample size may need to be larger than 30 to approximate normality. Stratified sampling can also be used to ensure representation of different subgroups within the population, but it does not affect the assumption of normality or unbiasedness. Overall, ensuring that these assumptions are met can increase the accuracy of statistical inference based on the sample mean.
An unbiased random sample ensures that each member of the population has an equal chance of being selected, and stratified sampling involves dividing the population into homogeneous subgroups and selecting samples from each subgroup. This method can provide more accurate and representative results when analyzing population characteristics.

ive been finding it rlly difficult pls can someone explain it in depth?
Answer:
The history class started at 2:35 pm
Step-by-step explanation:
To find the before time or starting time, we need to subtract 55 min from 3:30.
We cannot subtract 55 min from 30 min.
1 hour = 60 minutes. 3 : 30 can be written as 2: 90 minutes
Now subtract,
2 : 90
- : 55
2 : 35

What is the volume of the smaller cylinder?
V = 1000
Put the sides together: 4/6
Cube the sides (for volume you cube): 64/216
Then put the volume across from the side that has that volume: 64 x
----- = -----
216 3375
Cross multiply.
It should then equal this: 216x=216000
Divide by 216 and then you find x, which in other words the volume
x = 1000

Answer:
6 books
6 packages of mints
It would cost $240.00 is carpet was purchased.
Step-by-step explanation:
If 2 books cost 16.40, then one book costs 16.40/2 = 8.20 each.
50/8.20 = 6.1 rounded. You cannot buy part of a book, so 6 books may be purchases.
If 2 packages of mints cost .69, then I package costs .69/2 = .345
2.25/ .345 = 6.5 rounded. You cannot buy .5 of a package, so you can purchases 6 packages.
192/16 = 12

what properties of equality can justify the two steps in the solution
A.addition and division property
B. addition and multiply property
C. subrtraction and mutiply property
D. subtraction and division property
Answer:
A. Addition and division property--------------------------
The first step involves addition of 7 to both sides and the second step involves division of both sides by 9.
They indicate the addition and division property of equality respectively.
Therefore correct choice is A.
Circle w is dilated ( radius square root of 30) using a scale factor of 2.5 centered at the origin. What is the area of the resulting image?
The area of the resulting image after the dilation is 187.5π square units.To find the area of the resulting image after the dilation, we need to calculate the area of the dilated circle.
The formula for the area of a circle is A = πr^2, where A represents the area and r represents the radius.
Given that the radius of circle w is the square root of 30, we can calculate its area as follows:
Area of circle w = π * (√30)^2 = π * 30 = 30π
Now, we need to apply the dilation with a scale factor of 2.5 to find the area of the resulting image.
The scale factor affects both the radius and the area. When a circle is dilated by a scale factor of k, the new radius becomes k times the original radius. In this case, the new radius is 2.5 * √30.
Area of resulting image = π * (2.5 * √30)^2 = π * (2.5^2 * 30) = π * (6.25 * 30) = 187.5.
