What is the median of the numbers 8.7, 8.7 8.9, 9.0, 9.1, 9.2? I know I'm supposed to find the middle number, but there's an even amount of numbers here. So I'm supposed to find the average of the two middle numbers, which are 8.9 & 9.0. What does it mean when it says I'm supposed to "find the AVERAGE of the two middle values"?

If the value of a dependant variable decreases as the independent variable increases the function is said to be an inverse function.

A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.

When the value of a dependant variable decreases as the independent variable increases the function will be

We know that in inverse relation if the value of the independent variable (x) increases then the value of the dependent variable (y) decreases.

Then the value of y is inversely proportional to the value of x.

The two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34

An expression is combination of variables, numbers and operators.

Robbie's number = 4J + 9, where J is Jennie's number.

Now we can use this expression to find Willie's number:

Willie's number = 3(4J + 9) - 2 = 12J + 25

So one equation that describes Willie's number is:

W = 12J + 25

Kylie found another expression that equals Willie's number, so we can find it by solving for J in Robbie's expression and substituting it into Willie's expression:

Robbie's number = 4J + 9

4J = Robbie's number - 9

J = (Robbie's number - 9)/4

Substitute this expression for J into Willie's expression:

W = 12J + 25

W = 12[(Robbie's number - 9)/4] + 25

W = 3(Robbie's number - 9) + 25

W = 3(4J + 9 - 9) + 25 (substituting 4J + 9 for Robbie's number)

W = 12J + 34

So another equation that describes Willie's number is:

W = 12J + 34

Therefore, the two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34

Answer: its A

Step-by-step explanation:

The area of the mural is 1056 in² and the base is 32 inches. We have to determine the height of the mural.

Area of parallelogram = [tex] b \times h [/tex]

where 'b' is the base and 'h' is the height.

1056 [tex] in^{2} [/tex] = 32 [tex] \times h [/tex]

[tex] h=\frac{1056}{32} [/tex] in

Therefore, the height of the mural is 33 inch.

The first step to solve this problem is to formulate equations. Since the triangle has two equal sides, you can conclude that the angles adjacent to the sides are equal which means:

3x – 11 = 2x + 11

We can now solve for the value of x:

3x – 2x = 11 + 11

x = 22

The sum of the angles of a triangle is 180 so we can formulate another equation:

3x – 11 + 2x + 11 + 2y = 180

5x + 2y = 180

Remember that the value of x is 22 so you should substitute the value of x:

5(22) + 2y = 180

110 + 2y = 180

2y = 180 – 110

2y =70

y = 35

Answer:  The correct option is

(b) 1.

Step-by-step explanation:  We are given to find the value of c for which the following relation is a function :

R =  {(2,8) (12,3) (c,4) (-1,8) (0,3)}.

We know that

a relation is a function if each first element is associated with only one second element.

Since the first elements in R are 2, 12, -1 and 0, so, the value of c cannot be equal to these four values.

Therefore, the only option for c is 1.

Thus,  c = 1.

Option (b) is CORRECT.

Answer:

Identify the variable as the number of runs. Identify the inequality symbol needed as greater than. Identify the constant as 5 runs. Write the inequality as r > 5.

The height of the second triangle is 4 feet, which is found by using the formula for the area of a triangle (A = bh/2) and equating the area of the first triangle to that of the second.

To find the height of the second triangle with the same area as the first, we use the formula for the area of a triangle, A = bh/2, where b is the base and h is the height. The area of the first triangle with a base of 20 feet and height of 5 feet is:

Since the second triangle must have the same area, we can set up the equation:

Solving for the height (h2) of the second triangle:

Therefore, the height of the second triangle is 4 feet.

The decimal equivalent to 50/100 is 0.50, which is found by dividing 50 by 100.

The decimal equivalent to 50/100 is 0.50. This is because 50/100 is the same as dividing 50 by 100, which gives you 0.50.

This conversion is a standard way of expressing fractions where the denominator is 100, and it's commonly used to convert fractions into percentages or decimals.

For example, to convert 1/4 to a percent, you multiply by 25 (since 4 times 25 equals 100) to get 25 percent, which is equivalent to the decimal 0.25.

So, 50/100 is equivalent to 0.5 as a decimal.

The width of the dog kennel is 5 feet, obtained by dividing the area (20 square feet) by one of the dimensions provided (4 feet).

The student is asking for the width of a dog kennel, given that the area is 20 square feet, and one dimension (possibly the length) is given as 4 feet. To find the width, we can use the formula for the area of a rectangle, which is Area = Length × Width. Since the area is given as 20 square feet and the length is given as 4 feet, we can rearrange the formula to solve for the width:

Width = Area ÷ Length

Width = 20 square feet ÷ 4 feet = 5 feet

Therefore, the width of the dog kennel is 5 feet.

The width of a dog kennel with an area of 20 square feet and a length of 4 feet is found to be 5 feet using the area formula for rectangles, which is Area = Length × Width. The width of the kennel is 5 feet.

To determine the width of a dog kennel with an area of 20 square feet and a length of 4 feet, we can use the formula for the area of a rectangle, which is:

Area = Length × Width

We have the area (20 square feet) and the length (4 feet), so we can solve for the width:

20 square feet = 4 feet × Width

To find the width, we divide both sides of the equation by the length (4 feet):

Width = 20 square feet / 4 feet

Width = 5 feet

Therefore, the width of the kennel is 5 feet.
