Question 16 (1 point) An object is thrown from the top of a building. The following data measure the height of the object from t
Archy [21]

Using a calculator, inserting the values of x and y, the correlation coefficient for the given data-set is of -0.9422.

<h3>How to find the correlation coefficient of a data-set?</h3>

Using a calculator, the correlation coefficient is found inserting the ordered pairs (x,y) in the calculator.

In this problem, we have that:

  • The values of x are: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5.
  • The values of y are: 112.5, 110.875, 106.8, 100.275, 91.3, 79.875, 70.083, 59.83, 30.65, 0.

Hence, using a calculator, the correlation coefficient is of -0.9422.

Which transformations of the graph of f(x) = -4x result in the graph of f(x) = 4x +3?
Furkat [3]

Answer:

Option 1

Step-by-step explanation:

If you flip the sign on the coefficient on x, then it will be a reflection over the x-axis. The + 3 is a trick. Make sure you don't forget that you flip the sign to see the direction you are moving the graph horizontally. In this case, it would be moving to the left, so your 1st option is correct.
