ŷ= 1.795x +2.195 is the equation for the line of best fit for the data

<h3>How to use regression to find the equation for the line of best fit?</h3>

Consider the table in the image attached:

∑x = 29,  ∑y = 74, ∑x²= 125, ∑xy = 288,  n = 10 (number data points)

The linear regression equation is of the form:

ŷ = ax + b

where a and b are the slope and y-intercept respectively

a = ( n∑xy -(∑x)(∑y) ) / ( n∑x² - (∑x)² )

a  = (10×288 - 29×74) / ( 10×125-29² )

  = 2880-2146 / 1250-841

  = 734/409

  = 1.795

x' =  ∑x/n

x' = 29/10 = 2.9

y' = ∑y/n

y' = 74/10 = 7.4

b = y' - ax'

b = 7.4 - 1.795×2.9

  = 7.4 - 5.2055

  = 2.195

ŷ = ax + b

ŷ= 1.795x +2.195

Therefore,  the equation for the line of best fit for the data is ŷ= 1.795x +2.195

What is the area of rectangle ABCD?
kotegsom [21]

The area of a 2D form is the amount of space within its perimeter. The area of the rectangle is 12 units². Thus, the correct option is A.

<h3>What is an area?</h3>

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

As per the given information, the graph of the rectangle can be made as shown below. It can be observed from the graph that the length of the rectangle and width of the rectangle are 4 units and 3 units, respectively. Therefore, the area of the rectangle is,

Area = 4 units × 3 units = 12 units²

Hence, the area of the rectangle is 12 units². Thus, the correct option is A.

Someone help me pleaseeeee​
Dafna11 [192]

In an isosceles triangle, there are two sides that are congruent.

In this case, AB and BC are congruent.

Knowing this, we know that AB = BC

Since we know the values of AB and BC, we can put them into the equation:

3x - 4 = 5x - 10

Subtract 3x from both sides:

-4 = 2x - 10

Add 10 to both sides to isolate 'x':

6 = 2x

Divide both sides by 2:

x = 3

Now that we know the value of the variable, we just have to input it into AB's equation:

3x - 4 = 3(3) - 4

3(3) - 4 = 9 - 4

9 - 4 = 5

<u>AB = 5</u>

Good luck!

What is BC?<br><br>Any help?
Aliun [14]

Answer:

<em>A. 10</em>

Step-by-step explanation:

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

d = \sqrt{(11 - 5)^2 + (-6 - 2)^2}

d = \sqrt{6^2 + (-8)^2}

d = \sqrt{36 + 64}

d = \sqrt{100}

d =10
