A die is tossed. Find p(less than 5/even)

ANSWER

The circumcenter is (2,1)

EXPLANATION

The midpoint of BC is (-3,2)

The equation of the perpendicular bisector of BC is x=2

The midpoint of AB is (-1,1)

The midpoint of AB is (-1,1)

The perpendicular bisector of AB is y=1.

These two lines intersect at (2,1).

The point of intersection of the perpendicular bisectors of a triangle is called the circumcenter of the triangle.

Based on the graph, the coordinates of the circumcenter of this triangle are (2, 1).

In Mathematics and Euclidean Geometry, a circumcenter is the point where perpendicular bisectors (right-angled lines to the midpoint) of the sides of a triangle meet together or intersect.

This ultimately implies that, the circumcenter of any triangle is always equidistant from all the rays (vertices) of that triangle.

By critically observing the graph of triangle ABC, we can logically deduce the following parameters;

Based on the equation of the perpendicular bisector of BC and AB, the coordinates of the circumcenter are (2, 1).

Answer:

f(x) = (x + 3) - 7

Step-by-step explanation:

the original function f(x) = x - 9 is the parent function f(x) = x shifted down 9 units

from f(x) = x - 9, we are told that the function is shifted 2 units up, this is a vertical shift. so we add 2 to -9

-9 + 2 = -7

we now have f(x) = x - 7

next we are told that the function is shifted 3 units to the left. this is a horizontal shift. a horizontal shift looks similar to this:

f(x) = (x ± b)

if a function is shifted to the left, we would use an addition sign. if it was going to the right, we would use a subtraction sign

the function looks like the following when we apply the above knowledge

f(x) = (x + 3) - 7 this would be our new function

The new function will be f(x) = (x + 3) - 9 + 2.

The function given is f(x) = x - 9. When this function is shifted 2 units up and 3 units to the left, the new function is obtained by transforming the original function accordingly.

Shifting up by 2 units means adding 2 to the function, and shifting 3 units to the left means substituting x+3  for x.

Thus, the new function, after applying the transformations, is:

f(x) = (x + 3) - 9 + 2

Simplifying the above transformation, we get:

f(x) = x - 4

First, rearrange the equations:

[tex]x + y = 0[/tex]

[tex] - x + y = - 1[/tex]

Then, do equation 1 minus equation 2 to cancel y:

[tex]x - - x = 2x[/tex]

[tex]0 - - 1 = 1[/tex]

[tex]2x = 1[/tex]

[tex]x = \frac{1}{2} [/tex]

Substitute x to find y:

[tex]y = - x = - \frac{1}{2} [/tex]

So the point of intersection is (1/2, -1/2), which is represented by graph 1.

Answer:

Given system of equations,

y = - x   ------(1)

y = x - 1 ------(2),

From equation (1) and (2),

-x = x - 1

-x - x = -1

-2x = -1

[tex]\implies x = \frac{1}{2}[/tex]

Again from equation (1),

[tex]y = -\frac{1}{2}[/tex]

Thus, the intersection point of the lines (1) and (2), is [tex](\frac{1}{2}, -\frac{1}{2})[/tex]

Hence, the below graph represents the solution to the system of equations.

Answer:

slope   3/5

Step-by-step explanation:

3x − 5y − 6 = 0

To find the slope, we want to solve for y

(y = mx+b   slope intercept form of the equation(

Add 5y to each side

3x − 5y+5y − 6 = 0+5y

3x-6 = 5y

Divide by 5

3/5x -6/5 = 5y/5

3/5 x -6/5 = y

The slope is 3/5 and the y intercept is -6/5

In tandem with general linear equation, the slope of the equation is 3/5

Another name for slope is gradient. From the general linear equation,

Y = mx + c

To determine the slope of the line 3x − 5y − 6 = 0,

Make y the subject of formula and make the equation in line with general linear equation.

When using the formula for the volume of a pyramid, substituting the given values of base area and volume results in a candy box height calculation of 20 inches.

The question asks about the height of a box of candy shaped like a triangular pyramid, given the volume and the area of the base. The volume of a pyramid is given by the formula V = 1/3 * Base Area * height. In this case, the box volume equals 120 in³, and the base area equals 18 in². We can use these values to solve for the height.

By rearrangement of the formula, height = V / (1/3 * Base Area). If we plug in the values, height = 120 in³ / (1/3 * 18 in²) = 20in. Therefore, the height of the candy box is 20 inches.

The height of the candy box is 20 inches.

To find the height of the candy box, we need to use the formula for the volume of a triangular pyramid, which is V = (1/3) * A * h, where V is the volume, A is the area of the base, and h is the height.

We are given that the volume is 120 in³ and the area of the base is 18 in², so we can plug these values into the formula and solve for h.

120 = (1/3) * 18 * h

Simplifying the equation, we get:

360 = 18h

Dividing both sides by 18, we find that h = 20.

Therefore, the height of the candy box is 20 inches.

From the question, we have the following parameters that can be used in our computation:

[tex]\dfrac{x + 1}{4x^2} + \dfrac{x + 1}{x^2}[/tex]

Take the LCM of the expression

So, we have

Expand the bracket

[tex]\dfrac{x + 1}{4x^2} + \dfrac{x + 1}{x^2} = \dfrac{x + 1 + 4x + 4}{4x^2}[/tex]

So, we have

P(-2,7)

P'(-2,-7), ANSWER

reflection across the x-axis rule:

(×,y) ===> (x,-y)

Easy way to do this is draw the point on graph paper and count the same units above/below the x-axis. This example you are 7 units above the x-axis so you would count 7 units below the x-axis giving you the point.

Reflection of a point across an axis involves flipping the sign of the coordinate for that axis. So the reflection of point P(-2,7) on the x-axis is P'(-2,-7).

The concept described in your question refers to the reflection of a point across the x-axis. Given a point P(-2,7), the reflection of this point across the x-axis, denoted as Rx-axis(P), reverses the sign of the y-coordinate. This happens because a reflection is a transformation that flips a figure across an axis of reflection.

So, if we consider P(-2,7) to reflect about the x-axis, we just switch the sign of y-coordinate. Therefore reflection of point P(-2,7) about x-axis will be P'(-2,-7).

The parent function of the given graph is:

                   [tex]F(x)=x^4[/tex]

Since, the graph of the function has four real zeros this means that the parent function must be a function of degree four.

Also, we know that if the degree of the parent function would be odd then the end behavior of the graph ( i.e. the behavior of the graph when x tends to infinity and when x tends to minus infinity ) must be in opposite direction.

But here the graph is in the same direction.

Answer:

Step-by-step explanation:

Let's say that D is the point where AB is split, so AD = x-6 and DB = x.

And let's say that E is the point where AC is split, so AE = x+6 and EC = x+20.

Triangle ADE is similar to triangle ABC.  Therefore:

(x-6) / (x-6 + x) = (x+6) / (x+6 + x+20)

Solving:

(x-6) / (2x-6) = (x+6) / (2x+26)

(x-6) (2x+26) = (x+6) (2x-6)

2x² + 26x - 12x - 156 = 2x² - 6x + 12x - 36

2x² + 14x - 156 = 2x² + 6x - 36

14x - 156 = 6x - 36

8x = 120

x = 15

So the length of AC is:

AC = x+6 + x+20

AC = 2x + 26

AC = 2(15) + 26

AC = 56

Answer:

x = 2√7, y = √21

Step-by-step explanation:

The textbook has right angles, so we can use Pythagorean theorem to find the missing lengths.

For the triangle on top of the textbook:

c² = a² + b²

8² = 6² + x²

64 = 36 + x²

28 = x²

x = √28

x = 2√7

For the triangle on the side of the textbook:

c² = a² + b²

7² = x² + y²

49 = 28 + y²

21 = y²

y = √21

Answer: A and B are independent events if P(A∩B)=P(A).P(B)=0.15.

Step-by-step explanation:

Let A be the event that a shopper buys bread.

Let B be the event that a shopper buys cheese.

So, P(A∪B)=100

Probability that a shopper buys bread during a visit to the grocery store =n 0.60

P(A) = 0.60

Similarly, Probability that a shopper buys bread = 0.25

P(B) = 0.25

Since A and B are independent then,

[tex]P(A\cap B)=P(A).P(B)=0.60\times 0.25=0.15[/tex]

So, A and B are independent events if P(A∩B)=P(A).P(B)=0.15.

Taken together, these three facts imply that triangles AOB and COB are congruent (side-side-side congruence postulate).

Now, it's not exactly clear whether A and C lie on the same line (it's possible that the figure is not drawn to scale). If they do, then both angles AOB and COB are right angles, so angle BOK has measure 45º, and so [tex]m\angle AOK=135^\circ[/tex].

By applying the theorems of an isosceles triangle and an angle bisector, m<AOK = 135 degrees.
