Answer:
Step-by-step explanation:
Recall that in a right triangle, sine is the ratio of the opposite side to the hypotenuse:
We are actually not given the opposite side in this case. However, since we know the hypotenuse and the adjacent side, we can use the Pythagorean Theorem to find the opposite side. So:
Let <em>a</em> be the adjacent side and <em>b</em> be the opposite side. <em>c</em> will be the hypotenuse.
Substitute:
Solve for <em>b: </em>

So, the opposite side measures 12.
Then sine will be:
Answer:
2610/10730
2610/10730 = 0.24324324
0.24324324 X 100 = 24.324324

Find the mean absolute deviation for the data set. {3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6}

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
Answer: B
Step-by-step explanation:
Since this is a 30-60-90 triangle, b=8(sqrt3) = 8sqrt3.
By the same logic, c=8(2)=16.
