Additive inverse of 3

lisov135 [29]

Answer:

-3 is the additive inverse of 3.

Step-by-step explanation:

Two numbers are additive inverses if they add to give a sum of zero. 3 and -3 are additive inverses since 3 + (-3) = 0. -3 is the additive inverse of 3.

What is the formula of additive inverse?

The additive inverse of a number is what you add to a number to create the sum of zero. So in other words, the additive inverse of x is another number, y, as long as the sum of x + y equals zero. For example, the additive inverse of the positive number 5 is -5.

For which data representation is the median the better measure of center? bar graph. the horizontal axis is unnumbered. the vert

ss7ja [257]

The data representation where the median is the better measure of the center is the third data representation.

<h3>How to illustrate the data?</h3>

From the information, the last bar graph is skewed to the right, since the values of its fourth and fifth bars are way smaller than the values of its first, second, and third graphs.

The drastically smaller values pull down the mean of the last bar graph. Comparatively, bar graphs one and two have symmetrical distributions of numbers on both sides of the central bar and this implies that their mean is balanced out on both sides and that neither of them is significantly skewed left or right.
