Answer:

YES

Step-by-step explanation:

let's organize our information :

  • We notice that the values of the height of the table are changing  as the height of the chais is changing
  • 75⇒46
  • 74⇒44
  • 76⇒47
  • 75⇒46
  • 72⇒43
  • 77⇒48
  • 76⇒47
  • 71⇒42

Notice how when the chair's height is growing by 1 the same happens for the tables

  • so they are proprtional
  • we can say tha x is the height of table is x and the height of the chais is y
  • x=71 y=42   x=72 y=43
  • when we added 1 to x the same happened for y x+1⇒y+1
  • notice : 71-42=29 , 72-43=29 so x-y= 29
  • then x=y+29

Answer:

Yes.

Step-by-step explanation:

If you write out the coordinates, you can see that you can do the Vertical Line Test and confirm that if you were to write a function, it would be an actual function. No 2 x-values can be the same y-values. The coordinates all have separate xy values (or the same exact xy values) and you can determine a function.

If θ is a first-quadrant angle in standard position with P(u, v) = (3, 4), evaluate cos 2 θ . -7/25 -1/5 7/25
Grace [21]

Answer:

-7/25.

Step-by-step explanation:

From the given point P we see that the hypotenuse =  √(3*2 + 4^2) = 5.

So cos  θ = 3/5

cos 2 θ =  2 cos^2 θ - 1

= 2 * (3/5)^2 -1

= -7/25.

A researcher measures daily driving distance from college and weekly cost of gas for a group of commuting college students. What
juin [17]

Answer:

There is a positive correlation between these two variables.

Step-by-step explanation:

Positive correlation is an association amid two variables in which both variables change in the same direction.  

A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

As the distance covered by the vehicle increases the amount of gas consumed also increases. Thus, the weekly cost of gas will also increase.

Thus, there is a positive correlation between these two variables.
