The mean number of days with 0. 01 inch or more precipitation per month for Lewiston, Idaho, is about 8. 7. Find the probability that in a given month
(a) There are exactly 9 days with 0. 01 inch or more precipitation.
(b) There are at most 9 days with 0. 01 inch or more of precipitation.
(c) There are more than 9 days with 0. 01 inch or more of precipitation
We will use the Poisson distribution, which is a probability distribution that models the number of events occurring in a fixed interval of time or space, given the average rate of occurrence and assuming that the events are independent and randomly distributed.
For this problem, we will assume that the number of days with 0.01 inch or more precipitation in Lewiston, Idaho, follows a Poisson distribution with parameter λ = 8.7.
(a) To find the probability that there are exactly 9 days with 0.01 inch or more precipitation, we can use the Poisson probability mass function:
P(X = k) = e^(-λ) * λ^k / k!
where X is the random variable representing the number of days with 0.01 inch or more precipitation, λ is the parameter of the Poisson distribution, and k is the number of events we are interested in.
Plugging in the values, we get:
P(X = 9) = e^(-8.7) * 8.7^9 / 9! ≈ 0.151
Therefore, the probability that there are exactly 9 days with 0.01 inch or more precipitation is approximately 0.151.
(b) To find the probability that there are at most 9 days with 0.01 inch or more precipitation, we can use the cumulative distribution function of the Poisson distribution:
P(X ≤ k) = ∑i=0^k e^(-λ) * λ^i / i!
Plugging in the values, we get:
P(X ≤ 9) = ∑i=0^9 e^(-8.7) * 8.7^i / i! ≈ 0.503
Therefore, the probability that there are at most 9 days with 0.01 inch or more precipitation is approximately 0.503.
(c) To find the probability that there are more than 9 days with 0.01 inch or more precipitation, we can subtract the probability of having 9 or fewer days from 1:
P(X > 9) = 1 - P(X ≤ 9) ≈ 0.497
Therefore, the probability that there are more than 9 days with 0.01 inch or more precipitation is approximately 0.497.

A large corporation with monopolistic control in the marketplace has its average daily costs, in dollars, given by 900 + 100x + x2 C = X = 180,000 – 50x dollars. Find the quantity that gives maximum profit
The quantity that gives maximum profit is 1,750 units.
To find the quantity that gives maximum profit, we first need to determine the profit function.
Profit = Total Revenue - Total Cost
Total Revenue is given by the price (p) times the quantity (q):
TR = pq
Since the corporation has monopolistic control, it can set the price to maximize profit. We can use the demand function
to find the price that will maximize profit:
Q = 180,000 - 50p
Solving for p, we get:
p = 3,600 - 0.02Q
Now we can substitute this into the profit equation:
Profit =[tex](3,600 - 0.02Q)Q - (900 + 100Q + Q^2)[/tex]
Simplifying:
Profit = [tex]-Q^2 + 3,500Q - 900[/tex]
To find the quantity that gives maximum profit, we can take the derivative of the profit function with respect to Q and
set it equal to zero:
[tex]d/dQ (-Q^2 + 3,500Q - 900) = 0[/tex]
-2Q + 3,500 = 0

a. The two companies charge the same for 14 tons of sugar.
b. The cost when the two companies charge the same is $7953.50.
a. Let's represent the amount of sugar as x, and the total cost as C. Then we can set up the following equations for each company:
Company 1: C = 5143 + 200.75x
Company 2: C = 5500 + 175.25x
To find the amount of sugar for which the two companies charge the same, we can set the two equations equal to each other and solve for x:
5143 + 200.75x = 5500 + 175.25x
25.5x = 357
x = 14
So the two companies charge the same for 14 tons of sugar.
b. To find the cost when the two companies charge the same, we can plug in x = 14 into either equation. Let's use Company 1's equation:
C = 5143 + 200.75x
C = 5143 + 200.75(14)
C = 5143 + 2810.50
C = 7953.50

HELP!!! A lake currently has a depth of 30 meters. As sediment builds up in the lake, its depth decreases by 2% per year.
This situation represents [exponential growth or exponential decay]
The rate of growth or decay, r, is equal to [. 98 or. 02 or 1. 02]
So the depth of the lake each year is [1. 02 or. 98 or. 02]
times the depth in the previous year.
It will take between [11 and 12 or 9 and 10 or 3 and 4 or 5 and 6]
years for the depth of the lake to reach 26. 7 meters
This situation represents exponential decay because the depth of the lake decreases over time.
Exponential decay is a mathematical term used to describe the process of decreasing over time at a constant rate where the amount decreases by a constant percentage at regular intervals. It is a type of exponential function where the base is less than 1.
In other words, the quantity is decreasing by a fixed percentage at regular intervals.
The rate of decay, r, is equal to 0.98 because the depth decreases by 2% per year.

A sample of an element with a half-life of 8 years has a mass of 10 grams after 100 years. What was the mass of the original sample?The half-life of an element is the time it takes for half of a given sample of that element to decay.
Let's assume that the original mass of the sample was x grams.
After the first half-life of 8 years, the mass of the sample would be x/2 grams.
After the second half-life (16 years total), the mass would be x/4 grams.
After the third half-life (24 years total), the mass would be x/8 grams.
We can continue this pattern until we get to 100 years (which is 12.5 half-lives):
Mass after 100 years = x/2^12.5
We also know from the problem that the mass after 100 years is 10 grams:
x/2^12.5 = 10

The area of the square is 16 square units.
The area of the rhombus is 24 square units.
Part 1: Using the distance formula, we can find the lengths of the diagonals:
Diagonal AC = √[tex][(7-1)^2 + (2-10)^2[/tex]] = √(36 + 64) = √100 = 10
Diagonal BD = √[[tex](12-(-4))^2 + (12-0)^2[/tex]] = √(256 + 144) = √400 = 20
Part 2: The area of a rhombus can be calculated using the formula: Area = (diagonal 1 x diagonal 2)/2.
So, for this rhombus, the area = (10 x 20)/2 = 100 square units.
Part 3: The area formulas for a square and rhombus are not interchangeable because they have different ways of computing their areas. A square has all four sides equal in length, while a rhombus has opposite sides equal in length. The diagonals of a square bisect each other at right angles, and each diagonal divides the square into two congruent triangles, so the area of a square is simply side length squared (Area =[tex]s^2[/tex]). However, the diagonals of a rhombus bisect each other at right angles, but they do not necessarily divide the rhombus into congruent triangles. Therefore, the area of a rhombus is calculated using the lengths of the diagonals (Area = (diagonal 1 x diagonal 2)/2).
For example, let's consider a square with side length 4 units and a rhombus with diagonals 6 units and 8 units.
The area of the square = [tex]4^2 = 16[/tex]square units.
The area of the rhombus = (6 x 8)/2 = 24 square units.

g(v) = ____
The most general antiderivative of the function g(v) = 5 cos(v) - 8/√(1-v^2) is 5 sin(v) + 8 arcsin(v) + C, where C is the constant of the antiderivative.
To find the antiderivative of the given function g(v), we can use the basic antiderivative rules. The antiderivative of 5 cos(v) is 5 sin(v), as the derivative of sin(v) is cos(v) and we only need to reverse the process.
Similarly, the antiderivative of -8/√(1-v^2) can be found using the inverse trigonometric function arcsin(v), as its derivative is -1/√(1-v^2). However, we need to include a constant of integration, denoted by C, as the antiderivative is not unique.
So the most general antiderivative of g(v) is 5 sin(v) + 8 arcsin(v) + C, where C represents the constant of the antiderivative. To check the correctness of the answer, we can differentiate it and verify if it gives us the original function g(v) as the result.

the radius of the area of a cylinder is 36m and it’s height is 46m. find the surface area of the cylinder in terms of
Surface area of the cylinder in terms of [tex]$\pi$[/tex] is [tex]$5904\pi m^2$[/tex].
How to find the surface area of the cylinder?The surface area of a cylinder can be calculated by adding the area of the two bases (which are circles) and the lateral area (which is the area of the curved surface).
The radius of the cylinder is given as 36m and the height as 46m. Therefore, the diameter of the cylinder is 72m (twice the radius). Using the formula for the area of a circle, we can calculate the area of each base:
[tex]$A_{base} = \pi r^2 = \pi (36m)^2 = 1296\pi m^2$[/tex]
The lateral area of the cylinder can be calculated using the formula:
[tex]$A_{lateral} = 2\pi r h$[/tex]
Substituting the given values, we get:
[tex]$A_{lateral} = 2\pi (36m) (46m) = 3312\pi m^2$[/tex]
Therefore, the total surface area of the cylinder is:
[tex]$A_{total} = A_{base} + A_{lateral} + A_{base} = 2A_{base} + A_{lateral}$[/tex]
Substituting the values we calculated, we get:
[tex]$A_{total} = 2(1296\pi m^2) + 3312\pi m^2 = 5904\pi m^2$[/tex]
So the surface area of the cylinder in terms of [tex]$\pi$[/tex] is [tex]$5904\pi m^2$[/tex].

Carl takes out a loan which accrues interest at a flat rate of 1.96% per quarter.
what is the equivalent yearly simple interest rate?
Carl will be charged 7.84% of the initial loan amount as interest.
When taking out a loan, it's important to understand the interest rate and how it will affect the total amount you will owe. In this case, Carl's loan accrues interest at a flat rate of 1.96% per quarter. This means that every quarter, Carl will be charged 1.96% of the initial loan amount as interest.
To determine the equivalent yearly simple interest rate, we use the formula: Yearly interest rate = Quarterly interest rate x 4. This formula works because there are four quarters in a year, so we can multiply the quarterly interest rate by four to get the annual interest rate.
In this case, the quarterly interest rate is 1.96%. Multiplying this by four, we get an annual interest rate of 7.84%. This means that over the course of a year, Carl will be charged 7.84% of the initial loan amount as interest.
Understanding the interest rate is important because it can significantly impact the total amount that you will owe on a loan. A higher interest rate means that you will pay more in interest over the life of the loan, which can make the loan more expensive overall.
By calculating the equivalent yearly simple interest rate, Carl can better understand how much he will owe in interest over the course of the loan and make an informed decision about whether or not to take out the loan.

A social scientist is interested in determining if there is a significant difference in the proportion of republicans between two areas of town. He takes independent random samples of 200 families in each area of town and a significance test was conducted. The p-value was 0. 416. What should be our conclusions?.
The p-value of 0.416 indicates that there is no significant difference in the proportion of Republicans between the two areas of town. Therefore, we fail to reject the null hypothesis and conclude that there is no evidence of a significant difference in the proportion of Republicans between the two areas of town.
Based on the given information, the p-value is 0.416, which is larger than the conventional level of significance (e.g., 0.05 or 0.01). Therefore, we fail to reject the null hypothesis that there is no significant difference in the proportion of republicans between the two areas of town.
In other words, we cannot conclude that there is a significant difference between the two areas. It is possible that any observed difference could be due to chance.
However, it is important to note that statistical significance does not necessarily mean practical significance, and further investigation may be needed to determine if there are any meaningful differences between the two areas in terms of the proportion of republicans.

Inayah claims that the pool is draining at a rate of 1. 36% per hour
The pool is draining at a rate of 1.36% per hour according to Inayah's claim.
What is the claimed rate at which the pool is draining?According to Inayah's claim, the pool is experiencing a draining at a rate of 1.36% per hour. This means that for every hour that passes, the pool's water level decreases by 1.36% of its total volume.
Understanding the rate at which a pool is draining is essential for monitoring and managing water levels. If the rate of drainage is accurate, it can help estimate how long it would take for the pool to reach a certain level or completely drain. Additionally, it aids in determining the necessary actions to maintain the pool's water balance and prevent potential issues such as overflow or inadequate water supply.
It is crucial to verify the accuracy of the claim by monitoring the pool's water level over a specific period. This can be done by measuring the change in water volume or using other reliable methods to ensure the drainage rate aligns with the claimed percentage.
