Answer:
Step-by-step explanation: 8*2x, 8*-14+13=4x-27
16x-112+13=4x-27
16x-99=4x-27
-4x -4x
12x-99=-27
+99 +99
12x = 72
/12 /12
x=6
Answer: If i'm correct i think the subsets of b are
={0},{1},{2},{0,1},{1,2} ,{2,0},{0,1,2},{phye}
Step-by-step explanation:
Answer:
0.12 is the required probability.
Step-by-step explanation:
We are given the following in the question:
A: next component brought in for repair is an audio component
B: event that the next component is a compact disc player
We have to evaluate:
0.12 is the required probability.
If they only scored one field goal they would start with 3, and if they scored one extra point on each touchdown that would be 7+7+3 that would equal 17. If they only scored one extra point between two touchdowns than it would be 3+7+6=16
Answer:
AC = 8√3 AC = 7.65
A = 43.17° AB = 16.8
B = 46.83° B = 27°
Step-by-step explanation:
FIRST TRIANGLE
by using pythagorus theorem:
Hypo² = Base² + height²
19² = 13² + AC²
AC² = 19² - 13²
AC² = 192
AC = √192
AC = 8√3
sinФ =base/hypo
sin A = 13/19
A = sin^-1 (13/19)
A = 43.17°
43.17°+ B + 90° =180 (sum of angles of triangle)
B = 180° - 133.17°
= 46.83°
<h3>SECOND TRIANGLE</h3>
TanФ = base/height
Tan 63° = 15 / AC
1.96 = 15/AC
AC = 15/1.96
AC = 7.65
AB² = AC² + BC²
AB² = 7.65² + 15²
AB² = 283.5
AB = √283.5
AB = 16.8
tan B = AC /BC
tanФ = 7.65/15
tanФ = 0.51
Ф = tan^-1(0.51)
B = 27°
