Answer:
Jada: 1
Diego: 4/3
Lin: 10/3
Step-by-step explanation:
To find MAD, you calculate the mean of the data sets (which you were given in this case), and then find the distance of each number in the data set from the mean. You then write all the distances down, and then find the mean of THAT. Now you have your MAD.
Example (Jada)
Data set: 4,4,4,6,6,6
Mean: 5
Distances: 1,1,1,1,1,1
Mean of distances (and therefore the MAD):
(1+1+1+1+1+1) divided by 6 = 1
Answer:
no
Step-by-step explanation:
Answer:
x = x - 4/6
false
Step-by-step explanation:
6(x - 1) - 4x = 2(3x - 5)
First, lets distribute the 6 to each item inside the parentheses on the left side. You can do this by multiplying the 6 by each term.
6 * x = 6x
6 * -1 = -6
6x - 6 - 4x = 2(3x - 5)
Next, we will combine like terms.
6x - 4x = 2x
2x - 6 = 2(3x - 5)
Now, let's look at the right side of the equation.
Let's distribute the 2 to each item inside the parentheses on the left side. You can do this by multiplying the 2 by each term.
2 * 3x = 6x
2 * -5 = -10
6x - 1 = 6x - 5
Immediately, we can tell this is false, but let's solve the equation just to make sure.
6x - 1 = 6x - 5
+1 +1
6x = 6x - 4
--- --------
6 6
x = x - 4/6
This is false.
Do you remember how to find the area of a circle ?
Big Fat Hint: The area of a circle is (pi) x (its radius)² .
Can you find the area of the big circle ... the one with radius = 18 m ?
Do that. The whole big circle, just as if there was nothing inside it, and
no shaded region.
I'll wait.
Now, can you find the area of the small circle ... the one with radius = 12 m ?
Do that.
I'll wait.
The area of the shaded region is just
(the area of the big circle) minus (the area of the small circle) !
I got 180 pi or roughly 565.2 m². I could be wrong. You should check it.
Use Pythagorus theorem:
a²+b²=c²
(12)²+(16)²=c²
400=c²
√400=c
20=c
Therefore, the hypotenuse would be 20 ft.
Hope I helped :)
