Can't get it very well can you help withs steps

Step-by-step explanation:

You probably have not been taught to calculate the correlation coefficient. You find this answer by knowing two things:

If the line fits the data points well, then the correlation coefficient is close to 1 or -1

Second, if, when x goes up then y goes down will be a negative number OR when x goes up then y goes up then it's a positive number

SO IN YOUR QUESTION, THE LINE IS GOING DOWN...ANSWER SHOULD BE NEGATIVE AND THE LINE FITS THE DATA WELL SO IT SHOULD BE CLOSE TO -1

CHOOSE A. -0.93

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
