Anitas a fast food chain specialising in hot dogs and garlic fries, keeps track of the proportion of its customers who decide to

ira [324]

The probability that one customer will place a take-out order is .45.
The probability that one customer will place an "eat in" order is .55.

Of 4 randomly selected customers, the probability that exactly 3 will order "take out" is given by the following:
 $C^4_3\times 0.45^3\times0.55^1\approx0.200475$

Determine an exact value for sin _ 3π/4-tan 5π/6

iris [78.8K]

Answer:

$\frac{3\sqrt{2}+2\sqrt{3}}{6}$ or $\frac{\sqrt{2}}{2}+\frac{\sqrt{3}}{3}$

Step-by-step explanation:

$\sin\frac{3\pi}{4}-\tan\frac{5\pi}{6}\\\\\sin\frac{3\pi}{4}-\frac{\sin\frac{5\pi}{6}}{\cos\frac{5\pi}{6}}\\ \\\frac{\sqrt{2}}{2}-\frac{\frac{1}{2} }{-\frac{\sqrt{3}}{2}}\\ \\\frac{\sqrt{2}}{2}+\frac{1}{\sqrt{3}}\\ \\\frac{\sqrt{2}}{2}+\frac{\sqrt{3}}{3}\\ \\\frac{3\sqrt{2}}{6}+\frac{2\sqrt{3}}{6}\\ \\\frac{3\sqrt{2}+2\sqrt{3}}{6}$

If ABD = (2x – 7)°, DBC = (8x + 16)°, and ABC = 159º, find ABD.

Genrish500 [490]

Step-by-step explanation:

ABD+DBC+ABC =180° ( TRIANGLE)

(2x-7)°+(8x+16)°+159=180°

2x+8x-7°+16°+156=180

10x+165=180

10x=180-165

10x=15

x=15/10

x=1.5
