A way to find the equation of a line that best fits this data include the following: A. Use the coordinates of points B and D to find the slope and then the equation of the line that passes through them.

In Mathematics, there are different characteristics that are used for determining the line of best fit on a scatter plot and these include the following:

By critically observing the scatter plot using the aforementioned characteristics, we can reasonably infer and logically deduce that data points B and D represent the line of best fit because they are in a linear pattern.

Answer:

Last option: {-5, -1, 2, 11}

Step-by-step explanation:

Required inequality is x > -6

That means every item in the set of values indicated should be > - 6

We should eliminate answers with - 6 since -6 is not greater than -6 it is ≥ -6

That leaves 2 and 4

When comparing negative numbers, a negative number which has absolute value greater than the absolute value of another number will always be less than the other number

For example, -11 has absolute value 11

- 6 has absolute value 6

11 > 6

So - 11 < -6

All the values in option 2 are therefore < - 6

Therefore last option is the correct one

-5 > -6, -1 > -6 and positive numbers are always greater than negative numbers

See explanation below

Step-by-step explanation:

△ABC is isosceles right triangle because AB = BC = 29. Therefore the height of △ABC (which we can call AD) will bisect base AC at 90 degrees.

We can calculate the height of AD using Pythagorean theorem with BC is the hypotenuse (which is 29), and the side DC (equals 1/2 AC = 40/2 = 20)

=> BC^2 = BD^2 + DC^2

=> BD^2 = BC^2 - DC^2 = 29^2 - 20^2 = 841 - 400 = 441

=> BC = 21

so area of △ABC = hb/2 = (21 x 20)/2 = 210

To find the circumradius, we need to use formula A = abc/4R

=> R = abc/4A

R = (29)(29)(40)/(4 x 210) = (29 x 29 x 10)/210 = 40.05

20 units is  the circumradius of the triangle which has side lengths 29, 29, 40.

A triangle is a three-sided polygon that consists of three edges and three vertices.

To find the circumradius of a triangle with side lengths a, b, and c, use the formula:

circumradius = abc / 4Δ

where Δ is the area of the triangle.

To find the area of the triangle, use Heron's formula:

s = (a + b + c) / 2

Δ = √(s(s-a)(s-b)(s-c))

where s is the semiperimeter of the triangle.

In this case, the side lengths of the triangle are 29, 29, and 40. The semiperimeter is:

s = (29 + 29 + 40) / 2 = 49

Using Heron's formula, the area of the triangle is:

Δ = √(49(49-29)(49-29)(49-40))

= √(49×20×20×9)

=√176400

= 420

Now, using the formula for the circumradius, we have:

circumradius = abc / 4Δ

= (29×29×40) / (4×420)

=20 units

Therefore, the circumradius of the triangle is 20 units

Answer: The dimensions of the park on the scale drawing is 12 inches and 20 inches.

Dimension

Actual dimensions:

Park = 600 feet by 1000 feet

Swing set = 25 feet by 100 feet

Swing set on the scale drawing= 0.5 inch by 2 inches

Hence:

Dimension of park on drawing:

Width =  600×1/50

Width = 12inches

Length = 1000×1/50

Length= 20inches

In conclusion the dimensions of the park on the scale drawing are 12 inches and 20 inches.

Answer:

312

Step-by-step explanation:

To find the median of a set of numbers, we need to arrange them in order from smallest to largest and then find the middle number. If there are an odd number of values, the median is the middle number. If there are an even number of values, the median is the average of the two middle numbers.

Arranging the given numbers in order from smallest to largest, we get:

21, 45, 121, 300, 312, 333, 347, 421, 614

There are nine numbers in the set, which is an odd number, so the median is the middle number. The middle number is the fifth number in the ordered list, which is:

Median = 312

Therefore, the median of the given set of numbers is 312.

Answer:

Length of the rectangle = 5 units
Width of rectangle = 4 units

Area of rectangle = 20 units

Area of triangle = 10 units

Step-by-step explanation:

Since I don't know the answer choices, I am assuming the base of the triangle as the length and the height as the width. Check your answer choices and switch 4 and 5 if it is the other way around

Using the graph

The rectangle formed by rotating the triangle and placing it along the original rectangle will have a length(base)
= length of the base of the triangle
= 5 units

The width of the rectangle will be the same as the height of the rectangle = 4 units

The area = length x width = 5 x 4 = 20 units

Area of triangle = half area of rectangle = 20/2 = 10 units

To solve this problem, we can use the equation:

2x = 72

Where x represents the price of one sweatshirt. We multiply by 2 because Rhiannon bought two sweatshirts.

Simplifying the equation we get:

x = 36

Therefore, each sweatshirt costs $36.

We used an equation to solve this problem.

y=3x

If you look at the graph you can see that it jumps from 3 to 6 to 9 to 12 which is multiplying by 3.

Answer: "B. -5"

Step-by-step explanation:

STEP 1: Plug -5 into the equation where "X" currently is; 10 (-5) - 5 = -55

STEP 2: Multiply 10 (-5) [-50].

STEP 3: Update the equation to reflect Step 2; -50 - 5 = -55

STEP 4: Subtract 5 from -50 [-55].

STEP 5: Update the equation to reflect Step 4; -55 = -55

It is true that -55 = -55, so, therefore, the answer is "B. -5."

Step-by-step explanation:

To divide by a fraction, we can invert the fraction and multiply.

So, 12 divided by 3/4 can be written as:

12 * 4/3

Simplifying this expression, we get:

= 48/3

= 16

Therefore, 12 divided by 3/4 is equal to 16.

12 divided by 1/3 is 1

9 divided by 1/4 is 2.25

1/8 divided by 4 is 0.5

12 divided by 1/3 is 4

When x is equal to -5, the value of the expression 5x^2 - 2x + 5 is 140, by substitution method.

To assess an articulation for a given worth of a variable, we can substitute the worth into the articulation and improve on it. For this situation, we are given the articulation 5x^2 - 2x + 5 and we are told to assess it when x is equivalent to - 5. To do this, we substitute - 5 for x in the articulation to get 5(- 5)^2 - 2(- 5) + 5. We then, at that point, improve on this articulation by first assessing - 5 squared, which is 25. We then increase 5 by 25 to get 125, and add 10 and 5 to find the last solution of 140. In this manner, when x is equivalent to - 5, the worth of the articulation 5x^2 - 2x + 5 is 140.

We can use the point-slope form of a linear equation to find the equation of the function:

y - y1 = m(x - x1)

where m is the slope of the line, and (x1, y1) is a point on the line.

First, we can find the slope of the line by using the two given points:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (4, 24) and (x2, y2) = (6, 30):

m = (30 - 24) / (6 - 4) = 3

Now we can use one of the two given points, say (4, 24), and the slope m = 3 to write the equation of the line in point-slope form:

y - y1 = m(x - x1)

y - 24 = 3(x - 4)

Simplifying this equation, we get:

y - 24 = 3x - 12

y = 3x + 12

Therefore, the equation of the linear function is y = 3x + 12.
