According to the given information in the question P(A) is mutually exclusive.

When two events are incompatible with one another, the specific addition rule is applicable in probability. It claims that the likelihood of either event happening is equal to the likelihood of each event happening individually. If two occurrences A and B are considered to be mutually exclusive, then P(A) + P(B) is the formula used to determine the likelihood that either event will occur (B).

Assuming that event A and event B are mutually exclusive event.

To prove: Aand B are mutually exclusive.

Condition:P(A or B)=P(A)+P(B)

P(A or B)=P(A)+P(B)

           = +

              =

              =

               =

               =

               =

P(A or B)=P(A)+P(B)

Therefore, the given equation satisfies the condition.

So, Event A and Event B are Mutually Exclusive events.

solution of the equation is: (1, 6 ). This can be solved by substitution method.

The meaning of such an equations in algebra is just a mathematical expression stating the equality between two mathematical terms. For instance, 6x + 5 = 11 is an equation where 6x + 5 and 11 are two expressions separated by the 'equal' sign.

Identity equations and conditional equations are the two types of equations. For just any value of both the variables, an equality remains true. Only such variables have values that make a condition expression true. Two expressions joined by an equals sign ("=") form an equation.

y = 5x + 1 .............(1)

4x + y = 10 ............ (2)

substitute y = 5x + 1 into (2)

4x + 5x + 1 = 10

or, 9x + 1 = 10 ( subtract 1 from both sides )

or, 9x = 9 ( divide both sides by 9 )

or, x = 1

substitute x = 1 into (1)

y = 5(1) + 1

or, y = 5 + 1

or, y = 6

Thus, solution of the equation is: (1, 6 )

Answer: a = 7, b = -4:

This equation can be rewritten as 7x = ax + b - 4.

Since the coefficients of x on both sides are equal, the equation becomes 7x = ax - 4, we can see that the equation has only one solution.

a = 4, b = 7:

This equation can be rewritten as 7x = ax + b - 7.

Since the coefficients of x on both sides are different, the equation becomes 7x = 4x + 7, we can see that the equation has no solution.

a = 7, b = 4:

This equation can be rewritten as 7x = ax + b - 4.

Since the coefficients of x on both sides are equal, the equation becomes 7x = 7x + 4, we can see that the equation has infinitely many solutions.

What is a property that is rectangular?

Properties of Rectangles: The basic characteristics of rectangles are: A quadrilateral is a rectangle. The different sides are parallel and at the same level. Each interior has an angle of 90 degrees.360 degrees is the total of all interior angles.

Let x be the measurement of the side of the rectangle that is perpendicular to the walls. After that, the expense for the ends and partitions is...

10x +20x +20x +10x Equals 60x

The other two sides of the rectangle will be priced at (1560 -60x), thus they will be long.

(1/2)(1560 -60x)/10 = 78-3x

The rectangle's area equals the sum of its two dimensions, hence area = x. (78 -3x)

This parabola opens downward and bears zeros at x=0 and x=78/3. The vertex of the parabola will be at x = (0 + 78/3)/2 = 13 78 -3(13) = 39, which is in the midst of these values. . different side dimension

When the enclosure side parallel to the partitions is 13 meters and the other side is 39 meters, the area is maximized.

The maximal area is therefore x*y=13*39=507

The original dimensions of the garden are width of 10 feet and a length of 12 feet.

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation.

Let's call the width of the garden w.

According to the problem, the length of the garden is 2 feet more than its width:

Length = w + 2

And the area of the garden is 120 square feet:

Area = Length * Width

Substituting the expression for Length from the first equation into the second equation:

Area = (w + 2) * w

Expanding the expression:

Area = w² + 2w

Setting the expression for the area equal to 120:

w² + 2w = 120

Expanding the expression to a quadratic equation:

w² + 2w - 120 = 0

Solving for w using the quadratic formula:

Factor the left side of the equation.

(w − 10)(w + 12) = 0

w − 10 = 0 or w + 12 = 0

w = 10 or w = − 12

Since width cannot be negative, the width is 10 feet.

Length = w + 2 = 10 + 2 = 12 feet.

The required measure of m ∠Q is 46 degrees for the given figure.

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

As per the corresponding angles property, we can write the equation would be as:

17x = 56 + (8x-2)

17x - 8x = 56 - 2

9x = 54

x = 6

Since m ∠Q = 8x-2

So substitute the value of x = 6 in the above equation,

Then, we get m ∠Q = 8(6) - 2 = 46 degree

Answer:

a) 40cm²

b) 150cm²

Step-by-step explanation:

a)

The area of the shaded region is equal to the area of the larger rectangle, minus the area of the smaller rectangle.

Knowing the formula for the area of a rectangle is bh (where b is base and h is height), we can find

Large rectangle area: bh = (20)(10) = 200cm²

Smaller rectangle area: bh = (12)(10) = 120cm²

The area of the shaded region is therefore 200-120cm²=80cm²

b)

The area of the shaded region is equal to the area of the larger triangle, minus the area of the smaller triangle.

Knowing the formula for the area of a triangle is 0.5bh (where b is base and h is perpendicular height), we can find

Large triangle area: 0.5bh = 0.5(20)(20) = 10(20) = 200cm²

Smaller triangle area: 0.5bh = 0.5(20)(5) = 10(5) = 50cm²

The area of the shaded region is therefore 200-50cm²=150cm²

Answer:a) 140 cm^

b)150m^2

Step-by-step explanation:

a)first find the area of big rectangle i.e rectangle

area of rectangle 1 = length ×breadth

area of rectangle = 10×20=200cm^2

now find area of small rectangle i e rectangle

area of rectangle 2 = 12×5=60cm^2

now subtract area of rectangle 2 from area of rectangle

area of shaded portion =200-60= 140cm^2

b)find area of big triangle i.e triangle 1....

area of triangle 1 = 1/2 × base × height...

area of triangle 1 =1/2×20×20 = 200m^2

area of triangle 2 =1/2×10×5 =25m^2

area of triangle 3=1/2×10×5= 25m^2

area of shaded portion = area of triangle 1 - area of triangle 2 - area of triangle

area of shaded portion =200-25-25 =150m^2

The equation in simplified slope-intercept form is y = (2/3)x + 4/3.

What is the slope-intercept form of the line?

The slope-intercept form is a way of writing a linear equation in the form of y = mx + b, where m is the slope of the line and b is the y-intercept.

To rewrite the equation 2x-3y+4=0 in simplified slope-intercept form, we need to rearrange the equation to get y by itself on one side of the equation.

To do this, we can add 3y to both sides of the equation:

2x + 4 = 3y

Then we can divide both sides by 3:

(2/3)x + 4/3 = y

Now we have the equation in the form of y = mx + b, where m is the coefficient of x, which is (2/3) and b is the constant term on the right side, which is 4/3.

Hence, the equation in simplified slope-intercept form is y = (2/3)x + 4/3
