what is -7 divided by 3/4 ?

Answer:

48

Step-by-step explanation:

Since it is a triangle, it should add up to be a total of 180 degrees.

I took 64 + 68 = 132

Since there's a missing angle, you can take 180 - 132 = 48

All the angles should add up to 180 so 64 + 68 + 48 = 180

The probability that all of the first 4 speakers will be history majors is 1/7 or approximately 0.143.

Explain probability

Probability is a mathematical concept used to determine the likelihood of an event occurring. It is represented by a number between 0 and 1, where 0 means the event is impossible and 1 means it is certain. Probability theory is widely applied in fields like science, engineering, and finance to analyze and predict the outcomes of random events.

According to the given information

The total number of ways to choose 4 students from 7 is given by the combination formula:

C(7, 4) = 7! / (4! * 3!) = 35

Out of the 7 candidates, 5 are history majors. So, the number of ways to choose all 4 candidates to be history majors is given by the combination formula:

C(5, 4) = 5! / (4! * 1!) = 5

Therefore, the probability of selecting 4 history majors out of 4 speakers is:

P = 5/35 = 1/7

So the probability that all of the first 4 speakers will be history majors is 1/7 or approximately 0.143.

Answer:

11.25 miles

Step-by-step explanation:

To figure out how many miles John will travel in 1/2 an hour, we can use the following formula:

distance = rate x time

We know the rate, which is the number of miles John can travel per hour. We can find this by dividing the total distance by the total time:

rate = distance / time

rate = 45 miles / 2 hours

rate = 22.5 miles per hour

Now we can use this rate and the given time of 1/2 an hour to find the distance:

distance = rate x time

distance = 22.5 miles per hour x 1/2 hour

distance = 11.25 miles

Therefore, John will travel 11.25 miles in 1/2 an hour at this rate.

Step-by-step explanation:

The monthly contribution is increased by $10.25 each month if the Stafford Loan taken by Jessica is not subsidized.

By dividing the loan amount by the number of months, one may determine the formula for calculating the monthly loan payments.

The compound interest can be calculated as follows,

Compounded Annuity = P \((1+ r/n)^{nt\)

Given:

P= $7175

R= 6.3%

So, Compounded Annuity = 7175 \((1+ 0.063/12)^{120\)

Compounded Annuity = $13449

As, the loan was subsidized at 5.28% interest rate.

Compounded Annuity = 7175 \((1+ 0.0044)^{120\)

Compounded Annuity = 12151

The monthly payments can be calculated as,

unsubsidized monthly payments = 13499/120

                                                        = $112

and, subsidized monthly payments = 12151 /120

                                                            = $101.75

So, the difference of the monthly payments is calculated as $10.25 on the subsidization of the Stafford loan.

Answer : There are 84 different ways that six letters can be grouped from nine letters total.

Now that we have determined that the problem deals with combinations, we can use the formula for combinations to calculate the number of ways that six letters can be grouped from nine letters total. The formula for combinations is:

C(n,k) = n! / (k! * (n-k)!)

Where n is the total number of items, and k is the number of items being chosen. In this case, n = 9 and k = 6. Plugging these values into the formula gives us:

C(9,6) = 9! / (6! * (9-6)!)

C(9,6) = 9! / (6! * 3!)

C(9,6) = 362880 / (720 * 6)

C(9,6) = 362880 / 4320

C(9,6) = 84

Therefore, there are 84 different ways that six letters can be grouped from nine letters total.

The value of the investment multiplier is 5.

Given that:

Consumption function: C = c0 + c1(Y − T)

Investment function: I = I0 − m(r)

Government spending: G = G0

Tax revenue: T = t0 + t1Y

Where, C = Consumption

GDP = Y = C + I + G

Disposable income = Y − T

Private saving = Y − T − CG

= Government spending

I = Investment

t0 = autonomous tax component

t1 = endogenous tax component

m(r) = investment multiplier

Finding the equilibrium values of GDP, consumption, disposable income, and private saving

To find the equilibrium values, we need to set Y = GDP,

C = Consumption, T = Tax revenue and

S = Private Saving.

So, Y = C + I + GY = c0 + c1(Y − T) + I0 − m(r)GDP

= (c0 + I0 + G0 + t0) + (c1 − m(r))Y − t1Y.

GDP = \([c0 + I0 + G0 + t0] / [1 − (c1 − m(r) + t1)]\)

Now, we need to calculate the value of consumption and private saving

Disposable income = Y − T

Disposable income = Y − (t0 + t1Y)

Disposable income = (1 − t1)Y − t0

Consumption = c0 + c1(Y − T)

\(= c0 + c1(1 − t1)Y − c1t0\)

Private saving = \((1 − t1)Y − (t0 + c0 + c1(1 − t1)Y − c1t0)\)

Private saving = \((1 − c1)(1 − t1)Y + (c0 − c1t0)\)

The expression of the investment multiplier in terms of c0 and/or c1 is:

\(ΔY / ΔI = 1 / [1 − c1 + m'(r)]\)

The values of c0 and c1 are 48 and 0.6, respectively.

Answer:

18 rows

Step-by-step explanation:

So there are 6 rows containing 40 vines, and 3x = 3(6) = 18 rows containing 45 vines.

By utilizing algebra and the given information, you can determine that there are 18 rows that contain 45 vines.

To solve this problem, we can make use of algebra. Let's denote the number of rows containing 45 vines as x and the number of rows containing 40 vines as y. According to the problem, there are three times as many rows containing 45 vines as there are rows containing 40 vines, so we can write this as x = 3y. We also know the total number of vines is 1050, and this can be represented as 45x + 40y = 1050.

Now we can substitute x = 3y into the equation 45x + 40y = 1050. That leaves us with 45*(3y) + 40y = 1050 or 135y + 40y = 1050. Simplifying this gives 175y = 1050. Hence, dividing both sides by 175, we find y = 6. As we know that x = 3y, substituting y gives us x = 3*6 = 18. Therefore, there are 18 rows with 45 vines.

To derive the differential equation governing the concentration profile of A in the particle, we can start by considering Fick's second law of diffusion.

Fick's second law states that the rate of change of concentration with respect to time is proportional to the second derivative of concentration with respect to distance. In this case, the distance is the radial direction within the particle.

Starting with Fick's second law in spherical coordinates, we have:

∂CA/∂t = (1/r^2) ∂/∂r (r^2 D∂CA/∂r)

Since the reaction is assumed to be first-order, we can write the reaction rate as rA = -kaCA, where ka is the rate constant. Substituting this into the equation, we have:

(1/r^2) ∂/∂r (r^2 D∂CA/∂r) = -kaCA

Next, we introduce the change of variable CA/CAs = (1/r) f(r), where CAs is the concentration at the catalyst surface. Differentiating f(r) with respect to r, we get:

∂CA/∂r = (∂/∂r) [(CAs/r)f(r)]

Applying the product rule and simplifying, we obtain:

∂CA/∂r = (-CAs/r^2)f(r) + (∂f/∂r)

Substituting this expression back into the original equation, we have:

(1/r^2) ∂/∂r (r^2 D[(-CAs/r^2)f(r) + (∂f/∂r)]) = -ka(CAs/r)f(r)

Expanding and simplifying, we get:

(1/r^2) ∂/∂r (r^2 D(∂f/∂r)) + kaCAs f(r)/r = 0

This is the derived differential equation governing the concentration profile of A in the particle.

To solve this equation, appropriate boundary conditions need to be specified. These typically include the concentration at the catalyst surface (r = R) and the concentration at the center of the particle (r = 0). The specific boundary conditions will depend on the problem at hand and any additional assumptions or constraints.

It's important to note that the equation obtained is a second-order differential equation with variable coefficients, which may require numerical or analytical methods for solving, depending on the specific conditions and assumptions of the problem.

Answer:

Step-by-step explanation:

Control charts are used to monitor and identify when a process is out of control. There are several situations that indicate an out-of-control process, and these can be recognized on a control chart. Here are five such situations:

A point falls outside the control limits: If a data point falls above the upper control limit or below the lower control limit, it indicates that the process is out of control. This suggests that there may be a significant change or variation in the process.

Nonrandom patterns: Nonrandom patterns in the data points on a control chart, such as a consistent upward or downward trend, cycles, or oscillations, suggest that the process is not stable. These patterns indicate the presence of special causes of variation.

Runs and streaks: A run or streak refers to a series of consecutive data points that are either above or below the central line on the control chart. Runs or streaks suggest a lack of randomness and indicate that the process is not in control.

Lack of points within control limits: If there are long stretches of data points that are consistently clustered near one control limit or the central line without points within the control limits, it suggests that the process is not stable and may be exhibiting a systematic bias or shift.

Excessive variation: If there is excessive variation in the data points on the control chart, indicated by a wide spread of points around the central line, it suggests that the process is not under control. This can be recognized when the data points exceed the expected range of variation. These situations provide clear indications that a process is out of control and requires investigation and corrective actions to address the underlying causes of the variations. Control charts help in quickly identifying these situations and facilitating timely interventions to maintain process stability and quality.
