The value of the the average [y] would be -

y(avg) = 9.4.

<h3>What is the general equation of a Straight line? What is linear regression?</h3>

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression

We have the following data points -

(0, 2), (4, 6), (7, 10), (9, 13), (11, 16)

The value of average [y] would be -

y(avg) = (2 + 6 + 10 + 13 + 16)/5

y(avg) = 47/5

y(avg) = 9.4

Therefore, the value of the the average [y] would be -

y(avg) = 9.4.

What is the value of s?<br> S=
barxatty [35]

Answer:

s = 1

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540

39s + 129 + 79 + 145 + 148 = 540 , that is

39s + 501 = 540 ( subtract 501 from both sides )

39s = 39 ( divide both sides by 39 )

s = 1

kolezko [41]

Answer:

2L+2W=P, where L is the length, W is the width, and P is the perimeter.

Step-by-step explanation:

To find the perimeter of a rectangle, you add the length twice and the width twice, which translates to W+W+L+L, or 2L+2W.

Helppp please quick points wrong answers will get reported
kotegsom [21]

to find the coordinates you'll need the cos and sin of the angle its just like with x and y:

(x,y)= (cos angle, sin angle)

to find the sin, you simply need to use these formulas:

sin² A + cos ² A= 1

sin A/ cos A= tan A

1.

sin² O + cos² O= 1

sin²O= 1- cos² O

sin²O= 1- (-9/41)²

sin²O= 1600/1681

sin O= V1600/ V1681

sin O= 40/41

2.

sin O/ cos O = tan O

(40/41)/(-9/41)= tan O

-164/9= tan O
