Complete question:
A bag contains 9 marbles, 3 of which are red, 3 of which are blue, and 3 of which are yellow. If three marbles are selected from the bag at random, what is probability that they are all of different colors?
The conclusion is that in a bowl containing 9 marbles, at least 3 of them are red, at least 3 are blue, or at least 5 are said to be green.
What ae the marbles?The use of Pigeonhole Principle to prove the statement will be done in this question.
The Pigeonhole Principle is one that states that if there are more pigeons than pigeonholes, then at least one pigeonhole needs to have more than one pigeon.
So lets assume for contradiction that there are not at least 3 red marbles, 3 blue marbles, or 5 green marbles.
Case 1: There are fewer than 3 red marbles.
If less than 3 red marbles, then max 2 red marbles. 9 - 2 = 7 marbles left. 7 marbles: blue/green. With more than 3 marbles and assumed 2 red marbles, it violate the Pigeonhole Principle.
Case 2: There are fewer than 3 blue marbles.
If 3 blue marbles, then max 2 blue marbles. 9-2=7 marbles left, red or green. "More marbles than pigeonholes - against the Pigeonhole Principle."
Case 3: There are fewer than 5 green marbles.
5 green marbles, 4 green marbles. We have more marbles than pigeonholes, so against the Pigeonhole Principle.
So, there is contradiction in all 3 cases, our initial assumption that there are not at least 3 red marbles, 3 blue marbles, or 5 green marbles have to be false.
So, we can say that in a bowl containing 9 marbles, at least 3 of them are red, at least 3 are blue, or at least 5 are green.
Another is:
Total number of marbles=9
Number of red marbles=3
Number of blue marbles=3
Number of yellow marbles=3
So, the probability that they are all of different colors is 9/28.

The mean life of one make of keyboard is typically 6 years with a standard deviation of 1.3 years. If the manufacturer wishes to replace no more than 5 per cent of keyboards under guarantee, how long should the guarantee be, to the nearest month?
The make of one keyboard guarantee should be for about 58 months, or approximately 5 years.
We can use the normal distribution to model the lifetime of the keyboards. Let X be the random variable representing the lifetime of the keyboards, and let μ = 6 and σ = 1.3 be the mean and standard deviation, respectively.
To find the length of guarantee such that no more than 5% of the keyboards need to be replaced under guarantee, we need to find the value x such that P(X < x) = 0.05. We can standardize the variable by subtracting the mean and dividing by the standard deviation:
Z = (X - μ) / σ
Using the standard normal distribution table or a calculator with a normal distribution function, we find that the z-score corresponding to a cumulative probability of 0.05 is approximately -1.645.
Therefore,
-1.645 = (x - 6) / 1.3
Solving for x, we get:
x = -1.645 * 1.3 + 6 = 4.83
So the length of guarantee should be approximately 4.83 years. Converting this to months, we get:
4.83 years * 12 months/year ≈ 58 months
Therefore, the guarantee should be for about 58 months, or approximately 5 years.

Given y = 4e3x + Inv5x + 4 find the slope of the tangent at x = 1.5
Answer:
To find the slope of the tangent to the curve y = 4e^(3x) + (1/5)x + 4 at x = 1.5, we need to take the derivative of y with respect to x and evaluate it at x = 1.5.
The derivative of y with respect to x is:
dy/dx = 12e^(3x) + (1/5)
So, the slope of the tangent to the curve at x = 1.5 is:
dy/dx | x=1.5 = 12e^(3(1.5)) + (1/5)
dy/dx | x=1.5 = 12e^(4.5) + 0.2
dy/dx | x=1.5 ≈ 197.515
Therefore, the slope of the tangent to the curve y = 4e^(3x) + (1/5)x + 4 at x = 1.5 is approximately 197.515.
The slope of the tangent to the curve y = 4e^(3x) + 1/(5x) + 4 at x = 1.5 is approximately 512.558.
To find the slope of the tangent to the curve y = 4e^(3x) + 1/(5x) + 4 at x = 1.5, we need to take the derivative of y with respect to x and evaluate it at x = 1.5.
Taking the derivative of y with respect to x using the sum and power rules of differentiation, we get:
y' = 12e^(3x) - 1/(5x^2)
Now we substitute x = 1.5 to get:
y'(1.5) = 12e^(3(1.5)) - 1/(5(1.5)^2)
Simplifying, we get:
y'(1.5) = 12e^(4.5) - 1/11.25
Using a calculator, we can evaluate this expression to get:
y'(1.5) ≈ 512.558
Therefore, the slope of the tangent to the curve y = 4e^(3x) + 1/(5x) + 4 at x = 1.5 is approximately 512.558.

If $12,864 is invested in Jesaki Bank's 10-year CD that earns 2.3% compounded continuously, it will be worth $15,449.83 at maturity in 10 years. This calculation can be done using the formula:
A = Pe^(rt)
Where A is the amount at maturity, P is the principal amount (or initial investment), e is the mathematical constant approximately equal to 2.71828, r is the interest rate, and t is the time period.
Substituting the given values, we get:
A = 12864 * e^(0.023*10)
A = 12864 * e^0.23
A = 12864 * 1.258871
A = 15,449.83
Therefore, the amount invested in Jesaki Bank's 10-year CD will be worth $15,449.83 at maturity in 10 years, rounded to the nearest cent.
To find the maturity value of the CD after 10 years, we will use the formula for continuous compounding:
A = P * e^(rt)
Where:
A = Maturity value
P = Principal amount invested (in this case, $12,864)
e = Base of the natural logarithm (approximately 2.71828)
r = Annual interest rate (in decimal form, 0.023 for 2.3%)
t = Time in years (10 years)
Step 1: Convert the annual interest rate to a decimal.
2.3% = 0.023
Step 2: Plug the given values into the continuous compounding formula.
A = $12,864 * e^(0.023 * 10)
Step 3: Calculate the exponent part of the formula.
0.023 * 10 = 0.23
Step 4: Calculate the maturity value.
A = $12,864 * e^0.23 ≈ $16,079.95
So, after 10 years, the maturity value of the $12,864 invested in the Jesaki Bank 10-year CD with 2.3% interest compounded continuously will be approximately $16,079.95, rounded to the nearest cent.

P(X = 1) = 0.3033
d)
P(X = 3) = 0.1413
We have,
a. To find P(X = 2) when λ = 2.5, we can use the Poisson probability mass function:
P(X = 2) = (e^(-λ) x λ^X) / X!
Substituting λ = 2.5 and X = 2, we get:
P(X = 2) = (e^(-2.5) x 2.5²) / 2!
P(X = 2) ≈ 0.1839 (rounded to four decimal places)
b.
To find P(X = 7) when λ = 8.0, we can again use the Poisson probability mass function:
P(X = 7) = (e^(-λ) x λ^X) / X!
Substituting λ = 8.0 and X = 7, we get:
P(X = 7) = (e^(-8.0) x 8.0^7) / 7!
P(X = 7) ≈ 0.0573 (rounded to four decimal places)
c.
To find P(X = 1) when λ = 0.5, we use the same formula:
P(X = 1) = (e^(-λ) x λ^X) / X!
Substituting λ = 0.5 and X = 1, we get:
P(X = 1) = (e^(-0.5) * 0.5^1) / 1!
P(X = 1) ≈ 0.3033 (rounded to four decimal places)
d.
To find P(X = 3) when λ = 3.7, we can use the Poisson probability mass function:
P(X = 3) = (e^(-λ) * λ^X) / X!
Substituting λ = 3.7 and X = 3, we get:
P(X = 3) = (e^(-3.7) x 3.7³) / 3!
P(X = 3) ≈ 0.1413 (rounded to four decimal places)

Answer:
32.16 degrees
Step-by-step explanation:
The angle of depression in these problems is always the same as the angle of elevation.
With that in mind, lets solve this problem.
So we are given 2 triangle lengths. The Hypotenuse is 898 ft, and the height of your triangle is 478 ft.
There are three trig functions, sine, cosine, and tangent, but we will be using sin for this triangle because he have the opposite side to the angle(see how the side labeled 478 ft is opposite to the angle of elevation?) and the hypotenuse.
Sin is defined as opposite/hypotenuse.
Now, we make our equation:
sin(478/898) = x
x is your answer, just plug it into a calculator.
You get 32.16 degrees

The unit inventory carrying cost per year is 18 percent of the unit purchase cost. The cost to place and process an order from the supplier is $69 per order. Supplier A has a delivery lead time of 14 days. The store operates 300 days a year. Assume EOQ model is appropriate. If the manufacturer uses an order quantity of 1,146 units per order, what is the length of the inventory cycle in days for the store? Use at least 4 decimal places,
The length of the inventory cycle in days for the store when using an order quantity of 1,146 units per order is approximately 34.2216 days. To answer your question about the length of the inventory cycle in days for the store using an EOQ model and an order quantity of 1,146 units per order, we'll follow these steps:
Step:1. Calculate the EOQ (Economic Order Quantity) using the given information:
EOQ = √(2DS / H), where D is the annual demand, S is the ordering cost per order, and H is the holding cost per unit per year.
D = 10,054 units per year
S = $69 per order
H = 18% of the unit purchase cost ($83.4) = 0.18 * $83.4 = $15.012 per unit per year
EOQ = √(2 * 10,054 * 69 / 15.012) ≈ 1,146 units (the provided order quantity)
Step:2. Calculate the number of orders per year:
Number of Orders = Annual Demand / Order Quantity = 10,054 / 1,146 ≈ 8.7699 orders per year
Step:3. Calculate the inventory cycle length in days:
Inventory Cycle Length (Days) = (Operating Days per Year) / (Number of Orders per Year) = 300 / 8.7699 ≈ 34.2216 days
Therefore, the length of the inventory cycle in days for the store when using an order quantity of 1,146 units per order is approximately 34.2216 days.

The minimum number of dogs that have more than 27 kg is 4, and the maximum number of dogs that have more than 27 kg is 26.
We have,
To determine the minimum and maximum number of dogs that have more than 27 kg, we need to first find the cumulative frequency for the mass data.

Now, we can see that there are a total of 29 dogs.
To find the minimum and maximum number of dogs that have more than 27 kg, we can use the cumulative frequency table as follows:
The minimum number of dogs that have more than 27 kg is the frequency of dogs in the 30 ≤ x ≤ 40 category, which is 4.
The maximum number of dogs that have more than 27 kg is the total number of dogs minus the cumulative frequency for the 0 ≤ x ≤ 27 category, which is 3.
Now,
The maximum number of dogs that have more than 27 kg is:

What is the contrapositive of the conditional statement? If two variables are directly proportional, then their graph is a linear function
The contrapositive of the given statement is “If their graph is a linear function, then the two variables are directly proportional”, option B is correct.
The contrapositive of a conditional statement switches the order of the clauses and negates them both. In general, the contrapositive of a conditional statement has the same truth value as the original statement.
It can be a useful tool in logic and proofs because it can help simplify the statement and make it easier to prove or disprove. For example, if we wanted to prove the original statement, we could instead prove its contrapositive, option B is correct.

Step-by-step explanation:
Emma ate 2 apples, Jacob ate 2.5 apples, Isaac ate 1.25 apples and Mia ate 1.75 apples. What was the total number of apples that these 4 students ate?
Answer:
They ate a total of 7.5 apples.
Step-by-step explanation:
The total number of apples that these 4 students ate is:
2 + 2.5 + 1.25 + 1.75 = 7.5
Therefore, they ate a total of 7.5 apples.
Answer: 7.5
Step-by-step explanation: 2 + 2.5 = 4.5
4.5 + 1.25 = 5.75
5.75 + 1.75 = 7.5
Determine whether the integral is convergent or divergent. If it is convergent, evaluate it. (if the quantity diverges, enter diverges. ) [infinity] 0 1 6 1 x dx
a. Convergent
b. Divergent
The integral ∫[0,6] 1/x dx is divergent, An integral is said to be divergent if it does not have a finite value.
The given integral is:
[tex]∫[0,6] 1/x dx[/tex]
We know that the integral of 1/x is ln(x), and the antiderivative of ln(x) is xln(x) - x.
So, applying the limits of integration, we get:
[tex]∫[0,6] 1/x dx = ln(x)|[0,6] = ln(6) - ln(0)[/tex]
The natural logarithm of zero is unclear, so the indispensably isn't characterized at x = 0. In this manner, the indispensability is unique.
An integral is said to be divergent in the event that it does not have limited esteem. In other words, on the off chance that the fundamentally does not meet a genuine number, it is said to be unique.
There are a few reasons why a fundamentally may be unique. A few common reasons incorporate:
The integrand gets to be unbounded at a few points inside the limits of integration.
The integrand does not approach zero as the constraint of integration approaches boundlessness.
The limits of integration are interminable, and the integrand does not merge to a limited esteem as the limits approach interminability.
When an indispensably is disparate, it implies that the zone beneath the bend is interminable or does not exist.
This could have imperative suggestions in ranges such as material science and designing, where integrands are utilized to calculate amounts such as work, energy, and a liquid stream.
Thus, the answer is (b) Divergent.

the is the proportion of the total variation in the dependent variable explained by the regression model (or independent variable). A) coefficient of determination B) correlation coefficient C) slope D) standard error
The term you are looking for is the proportion of the total variation in the dependent variable explained by the regression model (or independent variable), which is known as the A) coefficient of determination.
The coefficient of determination, also known as R-squared, is a statistical measure that indicates the proportion of the total variation in the dependent variable that is explained by the regression model or independent variable. It ranges from 0 to 1, with higher values indicating a better fit of the model to the data. The other terms mentioned - variable, proportion, and independent - are all related to the concept of regression analysis, which is used to identify the relationship between a dependent variable and one or more independent variables, and to quantify the extent to which changes in the independent variables affect the dependent variable.

Help me with the question please. (10 points)
a rhombus is a parallelogram with a pair of opposite equal acute angles, a pair of opposite equal obtuse angles, and four equal sides.
in other words, it is a parallelogram with 4 equal sides, including a square as a special case.
the diagonal intersection point is the midpoint of both diagonals.
the diagonals intersect each other at a right angle (90°).
and they split each vertex angle in half.
so, they split the whole rhombus into 4 equal right-angled triangles.
and remember, the sum of all angles in a triangle is always 180°.
an "obtuse" angle means an angle larger than 90°.
an "acute" angle means an angle smaller than 90°.
because of all that, in the triangle PKE the angle K must be greater than 45° (90/2 = 45), so that the rhombus angle K can be "obtuse", as it must be twice the triangle angle K.
the triangle angle E is 90°.
so, the 16° must be triangle angle P.
and the triangle angle K is then
triangle angle K = 180 - 90 - 16 = 74°.
so, rhombus angle K = rhombus angle N = 2×74 = 148°
and triangle PMN angle N = 74°.
triangle PMN angle M = triangle PMN angle P = 16°.
