The value of the middle of the three is 25.

Let x be the first odd integer, then the next two consecutive odd integers are x+2 and x+4. The sum of these three consecutive odd integers is given as 75, so we can write the equation:

x + (x+2) + (x+4) = 75

Simplifying the left side of this equation gives:

3x + 6 = 75

Subtracting 6 from both sides gives:

3x = 69

Dividing by 3 gives:

x = 23

So the first odd integer is 23, and the next two consecutive odd integers are 25 and 27. The middle of these three is the second consecutive odd integer, which is 25. Therefore, the value of the middle of the three is 25.

The angle in the capital letter "L" measures 90°, making it a right angle.

A right angle is one that is exactly 90 degrees, or half of a straight angle. There is usually a quarter turn in it. The fundamental geometric forms, rectangle, and square, each have four angles that measure 90 degrees.

When two lines cross, and there is a 90-degree angle between them, the lines are said to be perpendicular. A few examples of 90-degree angles in real life include the angle between the hands of a clock at 3 o'clock, the angles between two neighboring sides of a rectangular door or window, etc.

This expression is P(exactly 2 emails between \(t and t+1) = 2rtje^-(r+j) / (r+j)^2\).

The expected length of the interval that t belongs to can be calculated by taking the sum of the expected time until the next event before t and the expected time until the next event after t. Since the Poisson processes are memoryless, the expected time until the next event follows an exponential distribution with parameter 1/r or 1/j, depending on the type of event. Therefore, the expected length of the interval is:

E[length of interval] = E[time until next event before t] + E[time until next event after t]

= (1/r) + (1/j)

To calculate the probability that t belongs to an RR interval, we need to find the probability that the last event before t is a regular email and the first event after t is also a regular email. Since the events are independent and follow a Poisson process, the probability of a regular email arriving at any given time is r/(r+j), and the probability of a junk email arriving is j/(r+j). Therefore, the probability of t belonging to an RR interval is:

P(RR interval) = P(regular email before t) * P(regular email after t)

= (r/(r+j)) * (r/(r+j))

= r^2 / (r+j)^2

To calculate the probability that between t and t+1, exactly 2 emails, a regular email followed by a junk email, arrive, we can use the fact that the number of arrivals in any time interval follows a Poisson distribution with parameter equal to the product of the rate and the length of the interval. Therefore, the probability of exactly 2 arrivals between t and t+1 is:

P(exactly 2 arrivals between t and t+1) = (rt)(jt)e^-(r+j)

The factor of (rt) represents the probability of a regular email arriving in the first infinitesimal interval between t and t+dt, and a junk email arriving in the next infinitesimal interval, and the factor of e^-(r+j) represents the probability of no arrivals in the remaining time interval (t+dt, t+1). The factor of (jt) represents the probability of a junk email arriving first, followed by a regular email in the next infinitesimal interval. We can think of the interval from t to t+1 as the unit interval, and normalize the probability by dividing by the total probability of any two emails arriving in the interval:

P(exactly 2 emails between t and t+1) = (rt)(jt)e^-(r+j) + (jr)(rt)e^-(r+j) / [(r+j)^2]

Simplifying this expression, we get:

P(exactly 2 emails between t and t+1) = 2rtje^-(r+j) / (r+j)^2

The proportion of employees who either have MBAs or are managers is 0.31, or 31%.

Let M be the event that an employee is a manager, and let B be the event that an employee has an MBA degree. We know:

P(M) = 0.15 (15% of the employees are managers)

P(B) = 0.25 (25% of the employees have MBA degrees)

P(B|M) = 0.6 (60% of the managers have MBA degrees)

We want to find P(M or B), the probability that an employee is either a manager or has an MBA degree.

We can use the formula:

P(M or B) = P(M) + P(B) - P(M and B)

To find P(M and B), we can use the conditional probability formula:

P(M and B) = P(B|M) * P(M)

Plugging in the values, we get:

P(M and B) = 0.6 * 0.15 = 0.09

Now we can plug in all the values to get:

P(M or B) = P(M) + P(B) - P(M and B) = 0.15 + 0.25 - 0.09 = 0.31

Answer: They both buy monthly passes.

Step-by-step explanation: Let's first calculate how much Alia and Matthew would pay if they both bought individual bus fares for the number of times they plan to ride the bus:

Alia: 25 rides x $2.35 per ride = $58.75

Matthew: 18 rides x $2.35 per ride = $42.30

Now let's see how much they would pay if they both bought monthly passes:

Alia: $45.75

Matthew: $45.75

Since the cost of buying individual bus fares is more than the cost of buying monthly passes, it would be more economical for both Alia and Matthew to buy monthly passes.

Therefore, yes, they both should buy monthly passes.

Here,

The differential equation (1-xy)y' = y^2

And,  y = e^xy is an implicit solution of the differential equation

(1-xy)y'=y^2.

What is Differential equation?

A differential equation is a mathematical equation that relates some function with its derivatives.

Now,

To show y = e^xy is an implicit solution of the differential equation

(1-xy)y'=y^2, we have to find the solution of differential equation.

The differential equation is;

\((1-xy)y'=y^2\\\\\\\\\)

\((1-xy) \frac{dy}{dx} = y^2\)

\(\frac{dx}{dy} + \frac{x}{y} = \frac{1}{y^{2} }\)

It is form of  \(\frac{dx}{dy} + Px = Qy\),

Where, P is the function of y and Q is the function of x.

Hence, Integrating factor = \(e^{\int\limits {\frac{1}{y} } \, dy} = e^{lny} = y\)

The solution is;

\(x y = \int\limits {\frac{1}{y^{2} }y } \, dy + c\)

\(xy = lny + c\)

Take c = 0, we get;

\(xy = lny\\\\y = e^{xy}\)

The multi-factor productivity of Cadbury's can be calculated by dividing the output (number of chocolate bars produced) by combined input factors (labor and overhead expenses). Correct answer is (c) 8.3 bars/$.

Multi-factor productivity measures the efficiency with which multiple inputs are used to produce a certain output. In this case, we need to calculate the productivity of Cadbury's by considering the number of chocolate bars produced and the combined input factors of labor and overhead expenses.

The number of chocolate bars produced in a day is given as 5000. Since a day is considered 8 hours, we can calculate the production rate per hour by dividing the total number of bars by the total hours:

5000 bars / 8 hours = 625 bars/hr. Therefore, option (a) 625 bars/hr is incorrect.

The combined input factors include the labor cost and the overhead expense. The labor cost per day is $200, and since there are 4 staff members, each staff member's cost would be $200 / 4 = $50. The overhead expense is given as $400 per day. Therefore, the total input cost is $400 (overhead) + $200 (labor) = $600.

To calculate the multi-factor productivity, we divide the output (number of bars) by the input cost: 5000 bars / $600 = 8.3 bars/$. Hence, the correct answer is (c) 8.3 bars/$, representing the multi-factor productivity of Cadbury's.

Answer: Side of an empty cubicle carton = 9 cm.

Now as we know that volume of the cube is the cube of its side.

So the volume of an empty cubicle carton having side 9 cm, V = (9)3=729 cm3.

Now we have to find out can 1000 cubes of side 1cm fit in it.

So the volume of the cube of side 1 cm is, V’ = (1)3=1 cm3

So the volume of the 1000 such cubes = 1000 (1) = 1000 cubic centimeters.

Now if the ratio of the volume of the empty cubicle carton to the volume of 1000 cubes of 1 cm is greater than 1 then we can will 1000 cubes of side 1 cm into an empty cubicle carton otherwise not.

So the ratio of the volume of the empty cubicle carton to the volume of the 1000 cubes is,

⇒VV′=7291000=0.729 < 1

So as we see that the ratio is less than one so we cannot fit 1000 cubes of side 1 cm into an empty cubicle carton of side 9 cm.

(a) To determine a nonzero vector orthogonal to the plane through the points P, Q, and R, we can first find two vectors in the plane and then take their cross product. Taking vectors PQ and PR, we have:

PQ = Q - P = (5, 1, -2) - (-4, 0, 0) = (9, 1, -2)

PR = R - P = (6, 4, 1) - (-4, 0, 0) = (10, 4, 1)

Taking the cross product of PQ and PR, we have:

n = PQ x PR = (9, 1, -2) x (10, 4, 1)

Evaluating the cross product gives n = (9, -17, 35). Therefore, (9, -17, 35) is a nonzero vector orthogonal to the plane through points P, Q, and R.

(b) To determine the area of triangle PQR, we can use the magnitude of the cross product of vectors PQ and PR divided by 2. The magnitude of the cross product is given by:

|n| = \(\sqrt\)((9)^2 + (-17)^2 + (35)^2)

Evaluating the magnitude gives |n| = \(\sqrt\)(811).

The area of triangle PQR is then:
