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:
∠ RQU = 25°
Step-by-step explanation:
The opposite angles of an inscribed circle are supplementary, thus
∠ URS + ∠ UTS = 180°, that is
∠ URS + 124° = 180° ( subtract 124° from both sides )
∠ URS = 56°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ URS is an external angle to Δ QUR, that is
∠ RQU + 31° = 56° ( subtract 31° from both sides )
∠ RQU = 25°
Answer:
y=1, x=2
Step-by-step explanation:
x+y=3
x-y=1
Using elimination method
x-x+y--y=3-1
2y= 2
y=1
Substitute y=1 into equation 2
x-1=1
x=1+1
x=2
