Scatterplots require both variables be quantitative and every least-squares regression line passes through (x , y).

Option 2 and 3 are true.

The values for two different numerical variables are represented by dots in a scatter plot (also known as a scatter chart or scatter graph). Each dot's location on the horizontal and vertical axes represents a data point's values. Scatter plots are used to see how different variables relate to one another.So here we required both variables to be quantitative.

So option 2 is correct.

The least squares line has a characteristic that has to do with a point that it passes through. A least squares line's y intercept may not be particularly interesting statistically, but there is one point that is

The center of each least squares line runs through the data. The x and y coordinates of this middle point are equal to the means of the x and y values, respectively.

So option 3 is also correct.

The  polar coordinates of the point that has rectangular coordinates (3, 2) are approximately (3.61, 33.69°).

To find the polar coordinates of a point given its rectangular coordinates, we can use the following formulas:

r = sqrt(x^2 + y^2)

θ = atan2(y, x)

Let's calculate the polar coordinates for the point (3, 2):

r = sqrt(3^2 + 2^2) = sqrt(9 + 4) = sqrt(13) ≈ 3.61

To calculate θ, we'll use the atan2 function, which takes into account the signs of both x and y:

θ = atan2(2, 3) ≈ 33.69 degrees

Therefore, the polar coordinates of the point (3, 2) are approximately (3.61, 33.69°).

The length of the line segment AB is 11/2 mm.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points.

Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know a line segment parallel to one side of a triangle divides the other two sides in the same ratio.

Therefore, AC/AB = EC/ED.

22/AB = 44/11.

2/AB = 4/11.

Step-by-step explanation:

From the given piecewise function that represent the amount of bill from number of units of electricity used is 'x' kWh.

b(x) = 0.10x   when x ≤ 200

         0.15(x - 200) + 20  when x > 200

For x = 400 kWh,

Function which represents the expenses of the bill,

b(400) = 0.15(400 - 200) + 20 [Since x > 200]

           = 0.15(200) + 20

           = 30 + 20

           = $50

The step that is the same when bisecting segments and angles is "Draw a ray from the vertex to another point."

When bisecting a segment, you must draw a line that divides the segment into two equal parts. One way to do this is to draw a ray with one endpoint at the midpoint of the segment and the other endpoint at any point beyond the segment. This ray will bisect the segment. When bisecting an angle, you must draw a line that divides the angle into two equal angles. One way to do this is to draw a ray from the vertex of the angle to any point on the angle. This ray will bisect the angle.

We will use a simultaneous approach since the rates are seemingly different.

We will create a relationship using the general line equation, y = mx + c.

Where:

y = Cost, C according to our question

m = line gradient

x = no of shirts, n

c = line intercept on y / cost axis, we will call this b since we already have C

Thus, we will have:

So, inputting variables from our question, we have:

We now substitute this value of m into the equation 1 to get:

Finally, we substitute the values of m and b into equation 0 to get:

Part A and B are fully answered and explained below.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

Because we are fully given points A and B, as well as the knowledge that ABC is a right triangle, we can assume that point C is the last needed point to form the right angle of this triangle. Meaning, point c has to have one identical coordinate out of (x, y) that is the same from each of our pre-existing coordinates in order to successfully form a right angle.

Due to the fact that we are told that Point C lies on y = 2, we know that it already has an identical 'y'-coordinate as Point A.

We can now decode that the x-coordinate of Point C must be identical to the x-coordinate of Point B, In this case, -2.

We can conclude that point C lies on (-2,2).

If we look at the length of the sides of the triangle, ignoring the hypotenuse, we can see that one is 4 units long and the other is 5 units long.

To find the area of a square the formula is

\(\boxed{\boxed{\bold{A = l \times w \times 0.5}}}\)

Since 4 x 5 = 20 and half of 20 is ten, we know that the final answer will be 10 units.
