The required probability of the randomly selected households either having internet access or cable television is equal to 0.85.

Let us consider 'A' represents the number of house hold has internet access.

And 'B' represents the number of house hold has cable television.

P(A) = 75%

      = 0.75

P(B) = 80%

       = 0.80

Number of household has both internet access and cable television

= P( A∩B)

= 70%

= 0.70

Probability of randomly selected household either with internet access or cable are P( A∪B) :

P( A∪B) = P(A) + P(B) - P( A∩B)

Substitute the value we get,

⇒  P( A∪B) = 0.75 + 0.80 - 0.70

⇒  P( A∪B) =  0.85

Therefore, the probability of household having either internet access or cable television is equal to 0.85.

Let's start by substituting the right-hand side of the equation into the left-hand side:

What does the math equation mean?

Two expressions are combined by the equal sign to form a mathematical statement known as an equation. For instance, a formula might be 3x - 5 = 16. After solving this equation, we learn that the value of the variable x is 7.

4y - 3 = 4(y + 1)

4y - 3 = 4y + 4

Now, we can isolate y by subtracting 4y from both sides:

0 = y + 4

-4 = y

So, there is a solution to the equation: y = -4. This means that Dawson is incorrect in saying that the equation has no solution.

Answer:

y=4x-30

Step-by-step explanation:

Answer: To find the solution to the equation 21/2 + x = 31/2, we need to isolate x on one side of the equation. Subtracting 21/2 from both sides gives us:

x = 31/2 - 21/2

Combining the fractions on the right side gives us:

x = 10/2

Dividing the numerator by the denominator gives us:

x = 5

So the solution to the equation 21/2 + x = 31/2 is x = 5. To fill in the bubbles on the grid, you would need to write the number 5 in the appropriate row and fill in the corresponding bubbles to indicate the digits of the number.

The zeroes of the equation is  0, 1 and 9.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

w³ -w² + 9w= 9

Now. solving for 'w'

w(w² - w + 9)=9

so, either w= 9 or w² - w + 9 = 9

w= 9 or w² - w = 0

w= 9 or w(w-1) = 0

w= 9 or w= 0, w= 1

The pair of measurements that is not equivalent is 25 g and 25,000 kg. Option A.

Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.

Here,

The pair of measurements that is not equivalent is 25 g and 25,000 kg.
25 g is a relatively small amount of mass, while 25,000 kg is a very large amount of mass. Therefore, these two measurements are not equivalent.

The other pairs of measurements are equivalent because they involve conversions between different units of the same base unit. For example:

16 g and 16,000 mg,  1 g = 1,000 mg, so 16 g = 16,000 mg

140 mg and 0.14 g, 1 g = 1,000 mg, so 0.14 g = 140 mg

5 kg and 5,000 g,  1 kg = 1,000 g, so 5 kg = 5,000 g

Thus, the pair of measurements that is not equivalent is 25 g and 25,000 kg. Option A.

The null hypothesis, denoted by H0, represents the status quo or the default assumption. In this case, the null hypothesis is that the average water consumption in Montana residences is 125 gallons per week.

The alternative hypothesis, denoted by Ha, is the hypothesis that the researcher is trying to prove. In this case, the alternative hypothesis is that the average water consumption in Montana residences is not equal to 125 gallons per week.

So, the null and alternative hypotheses for this problem are:

H0: μ = 125 (where μ is the population mean water consumption in Montana residences)

Ha: μ ≠ 125 (where μ is the population mean water consumption in Montana residences)

Note that the alternative hypothesis is a two-tailed hypothesis since we are testing whether the population mean is not equal to 125, which could mean it is either greater or less than 125.

The difference of the numbers of cookies produced by production lines A and B in a day is 280 cookies.

When two algebraic expressions are equated, a mathematical statement is called an algebraic equation. P = 0 or P = Q, where P and Q are polynomials, are the generic forms of algebraic equations. One variable only algebraic equations are referred to as univariate equations, while multiple variable algebraic equations are referred to as multivariate equations. A balanced equation in algebra is a given. Because of this, the right side of the equation will equal the left side.

Let the cookies produced by production line A = x.

Let the cookies produced by production line B = y.

Given that, the two production lines produce 7280 cookies in total each day.

x + y = 7280

Also, production line A produces 8% more cookies than production line B.

x = y + y(8/100)

x = y + 0.08y

x = 1.08y

The system of equations thus are:

x = 1.08y

x + y = 7280

Substitute the value of x in equation 2:

x + y = 7280

1.08y + y = 7280

2.08y = 7280

y = 3500

Substitute the value of y in equation 2:

x + y = 7280

x + 3500 = 7280

x = 3780

The difference between the cookies produced is:

D = x - y

D = 3780 - 3500

D = 280

Hence, the difference of the numbers of cookies produced by production lines A and B in a day is 280 cookies.

Answer:

Step-by-step explanation:

The equation h = -0.0159d² + 290 models the curve of the natural stone bridge, where h is the height of the curve in feet and d is the width of the curve in feet.

To find the vertex of the curve, we need to use the formula x = -b / 2a, where x represents the x-coordinate of the vertex and a and b are coefficients of the quadratic equation. In this case, the quadratic equation is h = -0.0159d² + 290, so a = -0.0159 and b = 0. To find the vertex, we plug these values into the formula:

x = -b / 2a = 0 / (2 * (-0.0159)) = 0

So the x-coordinate of the vertex is 0, which means the vertex is at the point (0, 290).

The vertex tells us that the highest point of the bridge (the vertex) is at a width of 0 feet. This means that the bridge is tallest at its center, and the height decreases as the width increases in either direction. Additionally, since the coefficient of the squared term is negative, the parabolic curve is downward-facing, which indicates that the bridge curves downward as it extends outward.

To find the span of the rainbow bridge, we need to find the width of the bridge where the height is 0. This represents the point where the bridge intersects with the river. To do this, we set h = 0 and solve for d:

0 = -0.0159d² + 290

0.0159d² = 290

d² = 290 / 0.0159

d ≈ 77.36

So the width of the bridge where the height is 0 is approximately 77.36 feet. Therefore, the span of the rainbow bridge is approximately 154.72 feet (twice the width at the point where the height is 0).

There are several ways to find the center of a triangle:

The Centroid: The centroid is a point that divides each median of the triangle into two equal parts. It is the average of the vertices of the triangle. To find the centroid, you simply average the x-coordinates and the y-coordinates of the vertices:

G = (x1 + x2 + x3)/3, (y1 + y2 + y3)/3

where (x1, y1), (x2, y2), and (x3, y3) are the coordinates of the vertices of the triangle.

The Circumcenter: The circumcenter is the center of the circle that passes through all three vertices of the triangle. To find the circumcenter, you need to find the midpoint of each side of the triangle and then draw perpendicular bisectors to each side. The point where the perpendicular bisectors intersect is the circumcenter.

The Orthocenter: The orthocenter is the point where the altitudes of the triangle intersect. The altitudes are the perpendicular lines from each vertex to the line that contains the opposite side. To find the orthocenter, you need to find the equations of the altitudes and then solve for the point where they intersect.

Note: If the triangle is an equilateral triangle, then the circumcenter and the centroid are the same. If the triangle is a right triangle, then the orthocenter and the circumcenter are the same.

Given equations,

a) x + 2y = 7

b) 3x - 4y = -39

Multiplying both equations

(x + 2y)(3x - 4y) = (7)(-39)

Using Foil method (a+b)(c+d) = ac + ad + bc + bd

3x² - 4xy + 6xy - 8y² = -273

3x² + 2xy - 8y² = -273

Which is a new equation.

Adding both equations

(x + 2y)+(3x - 4y) = (7)+(-39)

Adding like terms, we get

The term that describes a group of statements that executes as a single unit is a "block". A block of code is a program that is grouped together and treated as a single unit. So, the correct option is D.

In computer programming, a block is a group of statements or declarations that are enclosed within a set of curly braces ({ }). The block serves as a single unit that is executed together. Blocks are used to organize code and to apply control structures, such as loops and conditional statements, to multiple statements.

A block can contain any number of statements, which can include variable declarations, function calls, loops, conditional statements, and other constructs. The statements within a block are executed in sequence, one after another, unless a control statement is encountered that alters the normal sequence of execution.

For example, a while loop in Java consists of a block of code that is executed repeatedly while a certain condition is true:

while (condition) {

   // block of code to be executed while condition is true

}

In this example, the block of code inside the curly braces will be executed repeatedly while the condition specified in the while statement is true. The block can contain any number of statements, and these statements will be executed each time the loop iterates.

Another common use of blocks is to define functions or methods. A function or method is a block of code that can be called from other parts of the program, and can take inputs (arguments) and return outputs. For example, in Python, a function can be defined as follows:

def function(argument1, argument2):

Karen should order 41 square meters of carpet, and the cost will be $1,024.59 (taxes included).

An algebraic expression is a mathematical phrase that consists of variables, numbers, and mathematical operations such as addition, subtraction, multiplication, and division. It is a combination of constants, variables, and operators that represent a value or a relationship between values.

For example, "3x + 5" is an algebraic expression where "3" and "5" are constants, "x" is a variable, and "+" is an operator. The expression can be evaluated by substituting a value for "x" and performing the necessary operations.

Algebraic expressions can also be simplified by combining like terms and using the rules of arithmetic to simplify the expression. For instance, the expression "2x + 3x" can be simplified to "5x" by adding the coefficients of the like terms "x".

Algebraic expressions are used extensively in algebra to represent equations and relationships between variables. They are also used in a wide range of mathematical and scientific applications, including physics, engineering, and finance.

To calculate the amount of carpet Karen needs to order, we first need to convert the measurements of her living room from feet to meters:

Length: 18 feet = 5.4864 meters (rounded to four decimal places)

Width: 24 feet = 7.3152 meters (rounded to four decimal places)

To find the area of the living room in square meters, we multiply these two values:

Area: 5.4864 meters x 7.3152 meters = 40.0637 square meters (rounded to four decimal places)

Since Karen can only order full square meters of carpet, she should order 41 square meters (to be safe).

To calculate the cost of the carpet, we simply multiply the area by the cost per square meter:

Cost: 41 square meters x $24.99/square meter = $1,024.59

So Karen should order 41 square meters of carpet, and the cost will be $1,024.59 (taxes included).
