Answer:
7.83
Step-by-step explanation:
You know the sine of an angle in a right triangle is the ratio of the opposite side to the hypotenuse:
Sin = Opposite/Hypotenuse
sin(50°) = BC/BA = 6/?
? = 6/sin(60°) ≈ 7.83 . . . . units
AB ≈ 7.83 units

Answer:
860 points
Step-by-step explanation:
Let the number of points scored by the Arcado volleyball team =x
The Knight volleyball team scored 4 times as many points as the Arcado volleyball team. =4 X x=4x
Arcado scored 215 points
This means x=215
Therefore, the number of points scored by the Knight volleyball team
=4x
=4 X 215
=860 points
The Knight volleyball team scored 860 points.
Find the mean absolute deviation for the data set. {3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6}
Ratling [72]
Answer:
0.50
Step-by-step explanation:
The mean = 3 + 5 + 6+ 3 +2+ 2+ 1+0+ 0+ 4+ 7+ 4+ 5 + 5 + 6) / 15
= 53/15
= 3.533
Difference of values from the mean:
<u> n </u> <u> n - 3.533</u> (Absolute value)
3 0.533
3 0.533
6 2.467
3 0.533
2 1.533
2 1.533
1 2.533
0 3.533
0 3.533
4 0.467
4 0.467
5 1.467
5 1.467
6 2.567
7 3.467
Totals:
53 26.533
So the M.A.D. = 26.533 / 53 = 0.50
