What is the mean absolute deviation , 5, 1, 6, 2, and 3

MAD = 1.68

Step-by-step explanation:

So easily we calculate our mean => 5 + 1 + 6 + 2 + 3 = 17

17/5 = 3.4

3.4 is our mean or average

Now we find how much each of those is away from 3.4

--> 5 - 3.4 = 1.6

3.4 - 1 = 2.4

6 - 3.4 = 2.6

3.4 - 2 = 1.4

3.4 - 3 = 0.4

1.6 + 2.4 + 2.6 + 1.4 + 0.4 / 5 =

8.4 / 5 = 1.68

Thus, our mean absolute deviation (MAD) = 1.68

Hope this helps!

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
