Given are the system of equations as -

{C} = 12.10p + 5.25

{C} = 11.75p + 7.50

We can write the system of equations as

{C} = 12.10p + 5.25

{C} = 11.75p + 7.50

For the same amount, we will equate both the equations as -

12.10p + 5.25 = 11.75p + 7.50

12.10p - 11.75p = 7.50 - 5.25

0.35p = 2.25

p = (2.25/0.35)

p = 6.4

There were 200 police officers in year 2020.
There were 200 police officers on average each year.

Not enough information given

Answers

The function f(2020) = 200 tells us that there were 200 police officers in the year 2020.

Mathematically, an equation can be described as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.

The equation f(2020) = 200 tells us that in the year 2020, there were 200 police officers in the town. The function n = f(y) gives the relationship between the number of police officers, n, and the year, y.

So, when we put in the value of 2020 for y, we get the number of police officers in that year, which is 200.

2.¿qué operación es la que debes realizar para convertir un valor en pivote? a)suma de renglón más escalar. por ejemplo: r1 2 b)suma o resta de dos renglones. por ejemplo: r1-r2

Answers

The final equation in the system, and it can be used to solve for either x or y is x + 1.5y = 3

The pivot operation is used to solve linear equations. The operation starts by selecting a pivot element from a matrix. This pivot element is usually the first non-zero element in the first column of the matrix. The pivot element is then multiplied by a scalar to create a new equation. This new equation is then added to or subtracted from the other equations in the system to eliminate the coefficient of the pivot element. This process is repeated until the system of equations is solved.

For example, consider the following system of equations:

2x + 3y = 6

4x + 6y = 12

The first non-zero element in the first column is 2, so this will be our pivot element. To use the pivot operation, we multiply 2 by a scalar and add this new equation to the other equation. Let's use the scalar 4. This gives us:

8x + 12y = 24

Now we subtract this equation from the other equation to eliminate the coefficient of the pivot element:

2x + 3y = 6 - 8x - 12y = 24

This leaves us with:

-6x - 9y = 18

We now have an equation with only one variable. To solve for this variable, we can divide both sides by -6, giving us:

x + 1.5y = 3

This is the final equation in the system, and it can be used to solve for either x or y.

Answers

Answer:

343 meters per second (3 sf)

Step-by-step explanation:

1236km/h is basically 1236km per hour.

1km = 1000 meters

1h = 60 minutes

1m = 60 seconds

Using these rules, we can convert the kilometers and hour to meters and minutes and then to seconds.

---

1236km = 1236*1000

             = 1 236 000m

---

1h --> 1 236 000m

60m --> 1 236 000m

1m --> 1 236 000/60 = 20 600m

60s --> 20 600m

1s --> 20 600/60 = 343m (3 sf)

The subject is about finding the joint probability of two independent events: a repair done by Bob being done correctly and a repair done by Carl being done incorrectly.

The answer was determined using the formula for joint probability: P(A and B) = P(A) * P(B), where P(A) is the probability of event A and P(B) is the probability of event B, and A and B are independent events. In this case, event A is a repair done by Bob being done correctly and event B is a repair done by Carl being done incorrectly.

A quadratic function has x-intercepts at (-6,0) and the origin, and passes through (-5,-5). Write the equation of the quadratic function in standard form.
f(x)=blank

Answers

The equation of the quadratic function is:

f(x) = x^2 - 11x + 6

How can we explain it ?

The standard form of a quadratic function is given by:

f(x) = ax^2 + bx + c

We can find the values of a, b and c using the three points given in the question:

The x-intercepts of (-6, 0) and (0, 0) give us two equations:

f(-6) = 0 = a(-6)^2 + b(-6) + c = 36a - 6b + c

f(0) = 0 = a(0)^2 + b(0) + c = c

The point (-5, -5) gives us a third equation:

f(-5) = -5 = a(-5)^2 + b(-5) + c = 25a - 5b + c

Solving the system of three equations, we get:

a = 1, b = -11 and c = 6

Thus, the equation of the quadratic function is:

f(x) = x^2 - 11x + 6

What is quadratic equation ?

A quadratic equation is a polynomial equation of degree 2 that can be written in the form:

ax^2 + bx + c = 0

where x is an unknown variable and a, b, c are constants. The equation can be solved to find the values of x that satisfy the equation, which are referred to as the roots or solutions of the equation.

Given P(-4,17), Q (1,-3), R(-9,3), S(-5,4), slope of line PQ m(PQ) = -4 and slope of line RS m(RS) = 1/4 and Both lines are perpendicular.

What are perpendicular lines?

If two non-vertical lines in the same plane intersect at a right angle then they are said to be perpendicular. Horizontal and vertical lines are perpendicular to each other i.e. the axes of the coordinate plane.

To calculate the slope of the two lines;

Mathematically;

Slope = y2-y1/x2-x1

For PQ; slope will be;

Slope of line PQ m(PQ) = (-3-17)/(1-(-4)

Slope of line PQ m(PQ) = -20/5

Slope of line PQ m(PQ) = -4

For RS; slope will be;

Slope of line RS m(RS) = (4-3)/(-5-(-9))

Slope of line RS m(RS) = 1/4

We want to determine the relationship between the two lines.

The product of both is 1/4 * -4 = -1

When two lines are perpendicular, the product of their slopes is -1

We can conclude that both lines are perpendicular to one another.

A better score is the SAT score of 2100 which has an average of 1500 with an SD of 325.

- SAT score of 2100

Now, According to the question:

"Information available from the question"

An ACT score of 28 or a combined SAT score of 2100 when

ACT: μ = 21 and σ = 5;

SAT: μ = 1500 and σ = 325

In order to determine which is a better score, we compare the scores in standard deviation units.

We can convert the score to standard deviation units by subtracting the mean and dividing by the standard deviation.

ACT: (28-21)/5 = 1.2

SAT: (2100-1500)/325 = 1.38

As we see SAT score is better than ACT score as it is 1.38 standard deviation units above the mean, while the ACT score is only 1.2 standard deviation units above the mean.

Answers

The probability that he/she neither receives a text message nor an email during any weekend afternoon be 0.3000.

What is meant by probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Using the method for the union of two sets, we can calculate the number of students who receive either a text message or an email (or both) based on the above data:

Number of students who receive either a text message or an e-mail = Number of students who receive a text message + Number of students who receive an e-mail - Number of students who receive both

= 1364 + 857 - 470

= 1751

The proportion of students who don't receive either a text message or an email divided by the total sample of students is the probability that a student will not receive either:

P(neither T nor E) = (2500 - 1751) / 2500

= 749 / 2500

= 0.2996
