Write an algebraic expression that represents A less than 27.

Answer:

Her claim is false and she should use these to show that two data sets with the same median can have different variability. A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 4 to 9. A line divides the box at 7. A box-and-whisker-plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 5 to 8. a line divides the box at 7.  

Step-by-step explanation:

Even though both data sets have the same median (7) they don't have the same variability because they have different quartiles 1, quartiles 3 and interquartile range.

Answer:

6 and - 6

Step-by-step explanation:

Two numbers that are opposites and each more than 6 units away from 0 is (8, -8).

A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.

Given that, two numbers that are opposites and each more than 6 units away from 0.

Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it (8, -8).

Therefore, two numbers that are opposites and each more than 6 units away from 0 is (8, -8).

Answer:

two thirds

Step-by-step explanation:

I think that's the answer

The area of a circle is πr². We know r is 7, so the area is π * 7² = 49π.

Substituting, we have 49 * 3.14 = 153.86, which rounds to 153.9 centimeters squared.

The area of circle with a radius of 7 cm is,

⇒ 153.9 centimeters squared

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

Radius of circle = 7 cm

Now, We know that;

Area of circle is,

A = πr²

Where, 'r' is radius of circle.

Here, Radius of circle = 7 cm

Hence, The area of circle with a radius of 7 cm is,

⇒ A = πr²

⇒ A = 3.14 × 7²

⇒ A = 3.14 × 49

⇒ A = 153.9 centimeters squared

Thus, The area of circle with a radius of 7 cm is,

⇒ 153.9 centimeters squared

Answer:

5/6

Step-by-step explanation:

Since 1/3÷2/5 can also be written as 1/3/2/5

So the ÷ can then be converted to × and 2/5 will change to 5/2

So let's solve

1/3×5/2

5/6

Since there is no common number that can divide the two

So the final answer is 5/6

Answer:

Answer:

yes, this is a reasonable estimate

Step-by-step explanation:

47.81 x 3/11 = 13.04

The total cost for the first 11 photographs is $47.81.

To ascertain whether Alan's estimate for the cost of the last three photographs is reasonable, we will first compute the average cost of the first 11 photographs. Then, we will compare it to the estimated cost for the additional 3 photographs.

The total cost for the first 11 photographs is $47.81. To find the average cost per photograph, we divide this amount by the number of photographs:

$47.81 / 11 = $4.35 per photograph (rounded to the nearest cent).

Next, if Alan estimates the cost for 3 more photographs to be approximately $13.00, then the estimated cost per photograph for these would be:

$13.00 / 3 = $4.33 per photograph (rounded to the nearest cent).

Given that the average cost of the first 11 photographs is very close to the estimated cost of the additional 3 photographs, Alan's estimate is not only reasonable but also very precise.

Answer:

Y = mx + b

Step-by-step explanation:

Answer:

Considering the equation given:

[tex]y= 3x -2[/tex]

As a function:

[tex]f(x)= 3x -2[/tex]

[tex]$(2, -1)$[/tex] states for [tex](x, y)[/tex], which means, [tex]x=2[/tex] and [tex]y=-1[/tex]

[tex]f(2)= 3(2) -2\\f(2)= 6-2\\f(2)= 4[/tex]

[tex]4\neq -1[/tex]

Therefore, [tex]$(2, -1)$[/tex] is not a solution for the equation given and for the function.

Final answer:

To determine if (2,-1) is a solution of Y = 3X - 2, we substitute x=2 into the equation and simplify. The resulting y-value does not match the y-coordinate of the point, therefore (2,-1) is not a solution.

Explanation:

To verify whether the point (2,-1) is a solution to the equation Y = 3X - 2, we need to substitute the x-value of the point (2) into the equation and see if the resulting y-value equals the y-value of the point (-1). If they match, then the point is a solution of the equation.

Let's go through the step-by-step process:

Since the calculated y-value (4) does not equal the y-coordinate of the point (-1), the point (2,-1) is not a solution of the equation Y = 3X - 2.

Step-by-step explanation:

-32 + 32a -2 = 222

-34 + 32a = 222

32a = 256

a = 8

Answer:

[tex]a = 8[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex](-8 * 4) + (-8 * -4a) - 2 = 22[/tex]

[tex]-32 + 32a - 2 = 222[/tex]

Step 2:  Combine

[tex](-32 - 2) + 32a = 222[/tex]

[tex]-34 + 32a = 222[/tex]

Step 3:  Add 34 to both sides

[tex]-34 + 32a + 34 = 222 + 34[/tex]

[tex]32a = 256[/tex]

Step 4:  Divide both sides by 32

[tex]32a / 32 = 256 / 32[/tex]

[tex]a = 8[/tex]

Answer:

The square rug. The area of the rug is 39.69 ft² and is 0.33 ft² bigger than the rectangle rug.

Step-by-step explanation:

The find the area of a square, you multiply the length or the width (they all have the same length in a square) by the width (or the length), which would be the same exact number. So in that case—

The square has a side length of 6.3. To find the area of the square, we simply multiply 6.3 · 6.3 =39.69.

So, the area of the square is 30.69 ft²

————————————————————————————————————————

To find the area of a rectangle, you have to multiply the width by the length. (Or vise versa) This is showed by the following formula.

L·W=A

Where L=length, W=width, and A=area.

If the length is 8.2 and the width is 4.8, we can do the multiplicant equation that follows.

8.2·4.8= 39.36 ft².

Now that we have the area of both figures, we can compare them.

The square rug— 39.69

The rectangular rug— 39.36

Of we subtract the areas

39.69 and 39.36, we get the answer that the square rug is bigger by 0.33 ft².
