The probability that exactly two dog bite victims will arrive is 0.099.

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.

Based on the information, the probability that exactly two dog bite victims will arrive will be:

P(x = 2) = e^(-06) (0.6)2 / 2!

= (0.549) × (0.36) / 2

= 0.099

The probability is 0.099.

Pythagoras was a philosopher and a teacher. Pythagoras discovered that the square of the hypotenuse of a right-angled triangle, where one of the angles is 90 degrees, equals the sum of the squares of the other two sides: a2+b2=c2.

An angle with a measure of exactly 90 degrees (or /2) is referred to as a right angle. The proper angles are frequently demonstrated in everyday life. For instance, the edges of the cardboard or the corner of a book.

The right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection. The symbol is used to indicate a right angle.

A point is surrounded by four right angles. According to our definition of a degree, a "complete turn" around a point is 360°, making each right angle one-fourth of that, or 90°.

Answer:

The slope is [tex]\frac{-3}{5}[/tex]

Step-by-step explanation:

You know the slope is negative if you start on the left side and move right along the line.  You are moving down hill.  Down hill is a negative slope.

Answer:

-1.25 or -5/4

Step-by-step explanation:

I think it would be this because I remember that the slope formula is y2-y1/x2-x1 so using that you get 8-3/9-13 which simplifies to -5/4 which then turns into -1.25 when fully simplified. I think this is right.

The total impedance is 9+8i ohm.

From the question, we have

Z1= 2+9i

Z2=  7-i

we know,

total impedance in series,

Ztotal = Z1+Z2

            = 2+9i+7-i

            = 9+8i

The total impedance is 9+8i ohm.

Addition:

The act of combining two or more items is known as addition. The process of computing the sum of two or more numbers in mathematics is called addition. It is a fundamental mathematical procedure that is frequently used in daily life. When we work with money, figure out our food bills, or figure out the time, we frequently employ addition. One-digit numbers can be added simply for solving addition problems, however for bigger numbers, we divide the numbers into columns using their corresponding place values, such as ones, tens, hundreds, thousands, and so on.

The slope intercept form of equation of second graph is

d = 2.5t + 1

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]  

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The equation describing the graph of the position of the first object with respect to time is d=2.5t+2.2.

Now, we need to find the equation of line parallel to d = 2.5t + 2.2 and passing through t = 0, d = 1

Slope of line d = 2.5t + 2.2 is 2.5

Slope of line parallel to d = 2.5t + 2.2 is 2.5

The line passes through t = 0, d = 1

Equation of second graph =

d - 1  = 2.5(t - 0)

d = 2.5t + 1

The value of 2cos² (-22.5°)-1 is 1/√2.

In trigonometry, double angle identities or double angle trig identities are a set of trigonometric identities for angles of form 2θ. There are three double angle identities for each of sine, cosine and tangent ratios.

Given that, 2cos² (-22.5°)-1

2cos²x -1 = cos2x

2cos² (-22.5°)-1 = cos2(-22.5°)

cos(-45°)

∵ cos(-x) = cosx

∴ cos(-45°) = cos(45°)

cos(45°) = 1/√2

Hence, The value of 2cos² (-22.5°)-1 is 1/√2.

1) The way we transform the simultaneous equation in system A to system B is;

1 * Equation [A1] → Equation [B1]

2 * Equation [A1] + Equation [B1] → Equation [B2]

2) The way we transform the simultaneous equation in system Bto system C is;

1 * Equation [B1] → Equation [C1]

-1/11 * Equation [B2] → Equation [C2]

We are given the system of simultaneous equations as;

System A;

-7x + 2y = 5   ----A1

3x - 4y = 23  ------A2

System B;

-7x + 2y = 5   -----B1

-11x = 33  ------B2

System C;

-7x + 2y = 5   ----A1

x = -3  ------A2

1) To find out the operation that transforms system A into system B, we need to analyze both equations and by careful observation, we see that;

When we multiply A1 by 2 and add to A2, the result will give us B2.

Let us check;

A1 * 2 = 2(-7x + 2y) = 2(5)

-14x + 4y = 10

Add to A2 to get;

-11x = 33

2)  To find out the operation that transforms system B into system C, we need to analyze both equations and by careful observation, we see that;

When we multiply B2 by -1/11 and the result will give us C2.

Answer:

[tex]a_{n}[/tex] = 8 + (n-1)6

Step-by-step explanation:

The required function after shifting its origin will be g(x) = |x + 5| - 4

So, the answer is option C.

To move the origin's coordinates to (h, k):

Get the new equation by changing x and y in the given equation to (x-h) and (y-k), respectively.

Given functions f(x) = |x| or y = |x| in this case

Shift now five units to the left. x is changed to x - (-5) = x + 5.

Shift four units down, and y becomes y -(-4) = y + 4.

After shifting, the equation is now

y - k = |x - h|

y = |x -h| + k

y = |x - (-5)| +(-4) (-4)

g(x) = |x+5|-4

As a result, the necessary function will be g(x) = |x + 5| - 4 after changing its origin.

Option C is the correct response.

The standard form equation for a line passing through the point (6, -1) and parallel to the line denoted by 8x + 3y = 15 is 8x + 3y = 45.

The standard form equation

ax + by = c

Here a, b, and c are constants and therefore use the slope-intercept form.

y = mx + c .... (1)

where m is the slope, b = y-intercept

8x + 3y = 15

3y = -8x + 15

y = -8 / 3 x + 5

Slope (m) = - 8 / 3

It passes through a line that has points (6, -1)

Let's find b by putting the value of m = - 8/3, x = 6, and y = -1 in equation (1).

-1 = - 8 / 3 (6) + c

-1 = -48 / 3 + c

-1  = -16 + c

c = -1 + 16

c = 15

Therefore,

y = - 8 / 3 x + 15

8 / 3 x  + y = 15

=> 8x + 3y = 45

8x + 3y = 45 is the standard form of the line that passes through (6,-1) and is parallel to the line represented by 8x + 3y= 15.

It will take 84 hours to fill the pool.

Work is the amount of energy transferred to an object by an external force when it is moved over a certain distance.

Given that, an inlet pipe can fill a pool in 12 hours, while and outlet pipe can empty a pool in 14 hours.

Work done by inlet pipe in 1 hour = 1/12

Work done by outlet pipe in 1 hour = 1/14

Let the pool be filled in x hours, so in hour it will fill = 1/x

1/12-1/14 = 1/x

The y-intercept of a function is the value of y when x = 0, which is represented as the value of b in the slope-intercept equation y = mx + b. b is the y-intercept.

If an equation of graph that represents a function is given in slope-intercept form as y = mx + b, the value of b in the function is the value of the y-intercept of the y-intercept.

The y-intercept of the function is the same as the value of y when the value of x is 0, or the point where the line of the function intercepts the y-axis on a given graph that represents the function.

For example, if we are given the equation of a graph that represents a function as, y = 3x + 4, the y-intercept of the function would be 4.

In summary, the y-intercept of the function is the value of b in the equation of the function that is expressed as y = mx + b in slope-intercept form.
