The theoretical probability of drawing a blue marble from a jar containing 21 brown and 19 blue marbles is 19/40, or 0.475.

To calculate this, divide the number of blue marbles by the total number of marbles in the jar. 19 divided by 40 equals 0.475, or 19/40. This means that there is a 47.5% chance of drawing a blue marble from the jar.

The probability of drawing a specific marble from the jar can be expressed using the formula P(A) = n(A)/n(T).

In this example, the probability P(A) is the chance of drawing a blue marble, n(A) is the number of blue marbles (19) and n(T) is the total number of marbles in the jar (40). Therefore, P(A) = 19/40 = 0.475.

The mean (μ) of a hypergeometric distribution is given by: 8.181

The standard deviation (σ) of a hypergeometric distribution is given by:

1.644

Here, we have,

To find the mean value and standard deviation of the number of projects not among the first 15 that are from the second section, we need to calculate the probabilities for different numbers of projects from the second section.

Let's denote:

N1: Number of students in the first section (25)

N2: Number of students in the second section (30)

N: Total number of projects graded (15)

To calculate the probability of exactly 10 projects being from the second section, we can use the hypergeometric distribution.

The formula for the hypergeometric distribution is:

P(X = k) = (C(N2, k) * C(N1, N - k)) / C(N1 + N2, N)

Where:

X is the random variable representing the number of projects from the second section among the first 15 graded projects.

C(a, b) is the binomial coefficient, also known as "a choose b."

Using this formula, we can calculate the probability for X = 10:

P(X = 10) = (C(30, 10) * C(25, 15 - 10)) / C(55, 15)

Next, we can calculate the mean and standard deviation.

The mean (μ) of a hypergeometric distribution is given by:

μ = N * (N2 / (N1 + N2))

  = 15 * (30 / (25 + 30) )

  = 8.181

The standard deviation (σ) of a hypergeometric distribution is given by:

σ = √(N * (N1 / (N1 + N2)) * (N2 / (N1 + N2)) * ((N1 + N2 - N) / (N1 + N2)) )

  = √(15 * (25 / (25 + 30)) * (30 / (25 + 30)) * (25+30 - 15 )/(25+30)) )

  = 1.644

Compute the Gaussian density for the following cases. (a) x=0, m=0, s-1. Give the name of question5a (b) x-2, m=0, s-1. The value of the account on January 1, 2021, would be $2,331.57.

To calculate the value of the account on January 1, 2021, we need to consider the compounding interest for each year.

First, we calculate the value of the initial deposit after three years (12 quarters) using the formula for compound interest:

Principal = $1,000

Rate of interest per period = 8% / 4 = 2% per quarter

Number of periods = 12 quarters

Value after three years = Principal * (1 + Rate of interest per period)^(Number of periods)

                           = $1,000 * (1 + 0.02)^12

                           ≈ $1,166.41

Next, we calculate the value of the additional $1,000 deposit made on January 1, 2019, after two years (8 quarters):

Principal = $1,000

Rate of interest per period = 2% per quarter

Number of periods = 8 quarters

Value after two years = Principal * (1 + Rate of interest per period)^(Number of periods)

                         = $1,000 * (1 + 0.02)^8

                         ≈ $1,165.16

Finally, we add the two values to find the total value of the account on January 1, 2021:

Total value = Value after three years + Value after two years

                ≈ $1,166.41 + $1,165.16

                ≈ $2,331.57

Therefore, the value of the account on January 1, 2021, is approximately $2,331.57.

Given function is,f(t) ={ t, 0 < t < π π < t < 2π}

where f(t + 2 π) = f(t)

Let's take Laplace Transform of f(t)

                     L{f(t)} = L{t} + L{t + π}u(t − π) − L{t − 2π}u(t − 2π) + ...f(t + 2π) = f(t)

∴ L{f(t + 2 π)} = L{f(t)}⇒ e^{2πs}L{f(t)} = L{f(t)}

     ⇒ [e^{2πs} − 1]L{f(t)} = 0L{f(t)} = 0

when e^{2πs} ≠ 1 ⇒ s ≠ 0

∴ The Laplace Transform of f(t) is

                       L{f(t)} = L{t} + L{t + π}u(t − π) − L{t − 2π}u(t − 2π) + ...

The integrating factor needed to solve the given differential equation is μ(x) = e^(-2x^2y - 2xy + C).

To determine the integrating factor needed to solve the given differential equation:

(x^2y + 4xy + 4y) dx + (x^2 + 2x^2 + 4x - (x^2y - 2xy) dy = 0,

we follow these steps:

Write the differential equation in the form of:

M(x, y) dx + N(x, y) dy = 0.

Identify the coefficients of dx and dy:

M(x, y) = x^2y + 4xy + 4y

N(x, y) = x^2 + 2x^2 + 4x - (x^2y - 2xy) = 3x^2 + 4x + 2xy

Compute the partial derivative of M with respect to y:

∂M/∂y = x^2 + 4x.

Determine the integrating factor:

The integrating factor, denoted by μ(x), is given by:

μ(x) = e^(∫ (∂M/∂y - ∂N/∂x) dy).

In this case, ∂M/∂y - ∂N/∂x = (x^2 + 4x) - (3x^2 + 4) = -2x^2 - 4x.

Therefore, μ(x) = e^(∫ (-2x^2 - 4x) dy).

Integrating with respect to y, we get:

μ(x) = e^(-2x^2y - 2xy + C),

where C is the constant of integration.

Trevor and Kim will be situated 21 kilometers apart from each other at 1:30 PM. They will be separated by a distance of 21 km when the clock strikes 1:30 in the afternoon.

To determine at what time Trevor and Kim will be 21 km apart, we can set up a distance-time equation based on their relative speeds and distances.

Let's assume that t represents the time elapsed in hours since noon. At time t, Trevor would have traveled a distance of 8t km, while Kim would have traveled a distance of 6t km in the opposite direction.

Since they are running in opposite directions, the total distance between them is the sum of the distances they have traveled:

Total distance = 8t + 6t

We want to find the time when this total distance equals 21 km:

8t + 6t = 21

Combining like terms, we have:

14t = 21

To solve for t, we divide both sides of the equation by 14:

t = 21 / 14

Simplifying, we find:

t = 3 / 2

So, they will be 21 km apart after 3/2 hours, which is equivalent to 1 hour and 30 minutes.

Therefore, Trevor and Kim will be 21 km apart at 1:30 PM.

The monthly payment for a bank loan assuming a one-year repayment period and 13.5% interest is To calculate the monthly payment for a bank loan, we can use the formula:

Monthly payment = Total cost / Number of months

Given that the total cost is $1,800 and the repayment period is one year (12 months), we can substitute these values into the formula:

Monthly payment = $1,800 / 12 = $

Now, let's calculate the total cost for the bank loan:

Total cost = Monthly payment * Number of months

Total cost = $ * 12 = $

For the add-on method of interest calculation with a one-year repayment period and 11.5% interest, the monthly payment is $ (main answer).
The add-on method of interest calculation involves adding the interest to the principal amount and then dividing it by the number of months.

Given that the total cost is $1,800 and the repayment period is one year (12 months), we can calculate the interest as follows:

Interest = Total cost * Interest rate

Interest = $1,800 * 11.5% = $

Now, let's calculate the new principal amount:

New principal amount = Total cost + Interest

New principal amount = $1,800 + $ = $

Answer:

y = 1/2 x+4

Step-by-step explanation:

Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.

The slope can be calculated using the formula \(m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }\).

I'll be plugging in (2,5) and (4,6) to calculate the slope.

m = (6-5)/(4-2) = 1/2

The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.

Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4
