Just write down how you would figure out the cost per game.

first game is 7 people times $8.50 =

and so on

This word problem is a great example of needing to pull out only information you need and ignoring the rest.

Consider the four points (10,10), (20,50), (40,20), and (50,80). the least squares line is modifyingabove y with caret equals

lesya [120]

Answer:

The y-intercept of the least squares line is 7 and slope of the line is 1.1. It means x and y are positively related.

Step-by-step explanation:

Least squares : It is an approach to find a regression line such that the sum of squares of residual(difference between estimated point on the line and data point) is minimum.

The given points are (10,10), (20,50), (40,20), and (50,80).

The least squares line is

$y=7.0+1.1x$ .... (1)

The general form of least squares line is

$y=a+bx$ .... (2)

where, a is y-intercept and b is slope of the line.

On comparing (1) and (2) we get

$a=7.0,b=1.1$

It means the y-intercept of the least squares line is 7 and slope of the line is 1.1.

Slope is positive it means x and y are positively related.

Consider the surface f (x comma y comma z )f(x,y,z)equals=negative 2 x squared plus 2 y squared minus 3 z squared plus 3 equals

trapecia [35]

Answer:

a) (8,8,-6)

b) 4x+4y+3z = -3

Step-by-step explanation:

The surface is given by the equation

f(x,y,z) = 0 where

$f(x,y,z)=-2x^2+2y^2-3z^2+3$

The gradient of this function is the vector

$(\frac{\partial f}{\partial x},\frac{\partial f}{\partial y},\frac{\partial f}{\partial z})=(-4x,4y,-6z)$

If we evaluate it in the point P = (-2,2,1) we obtain the point

(8,8,-6)

The vectors with their tails at P are of the form

(-2,2,1)-(x,y,z) = (-2-x, 2-y, 1-z)

as they must be orthogonal to the gradient, they must be orthogonal to the vector (8,8,6) so their inner product is 0

$(-2-x,2-y,1-z)\cdot(8,8,6)=0\Rightarrow -16-8x+16-8y+6-6z=0\Rightarrow 4x+4y+3z=-3$

and the equation of the desired plane is

4x+4y+3z = -3

Perform the indicated operation. 11(-2) 22 9 -9 -22

ASHA 777 [7]

Answer:

-22

Step-by-step explanation:

When you multiply a positive and negative number together, it becomes negative.

Multiplication is repetitive addition.

11(-2) = -11 + -11 = -22
