Please help what is the answer

Mathematics
1 answer:
STALIN [3.7K]3 years ago

9514 1404 393

Answer:

  E

Step-by-step explanation:

You can see from the first and last points that the data set demonstrates a slight upward trend. That means the slope of the regression line will be near +1, eliminating all choices except A and E.

The y-intercept of such a line will not be negative, eliminating choice A, leaving choice E as the only reasonable option.

__

If you input this data to a suitable calculator or spreadsheet, it can find the parameters of the regression line for you. (We presume you have been introduced to such tools.) My graphing calculator gave the results shown below, confirming E is the correct choice.

How to solve this? Don't just give me the answer help me learn this.
Sphinxa [80]

Answer:

I'm not entirely sure but I think that what is says is that it wants you to find the value of x in (4x+28) to make it 116 degrees because it is that same angle. So what you do is you get (4x+28)=116 and you do this because they are the same angle so you use 116 and get it to solve x. Since I'm lazy, then I go to this website and type the equation in: m a t h w a y . c o m but without all of the spaces, I had to do that so it would let me answer this, but I'll do it the real way this time. (4x+28)=116  Their is a rule in math that as long as you do something to one side of the equal sign in the equation, you have to do it to the other and it will still work. So, you minus 28 from both sides so that you can get rid of it and you now have 4x=88. Now you should know this part but you divide 4 from both sides to make so x is alone. Now you have x=22 because you divided 4 from each side. So their is your answer: x=22.

Step-by-step explanation: If you have the answer key that you can check from to make sure you got it right because I know some teachers let you do that, then you should make sure that is right, but I am pretty sure it is.

Andrew [12]

Answer:

The coefficient is -2,

The terms being added are -2x and -3

The constant is -3

The variable is x

Step-by-step explanation:

The coefficient is the number that's attached to the variable, in this case, it's -2

The terms being added are -2x and -3 because you can write subtraction like this....

-2x + (-3)

The constant is -3 because any number that doesn't have a variable attached to it is a constant value.  It doesn't change depending on any variables

The variable is x because in this case, using different values for x changes the value of the equation, so it can vary, depending on the value of x
