ipn [44]

Answer:

Prob = 95.0%

Explanation:

There are 382 people in total

69 respond and are in the 18-21 age bracket

12 refuse to respond and are in the 18-21 age bracket

282 respond and are in the 22-29 age bracket

19 refuse to respond and are in the 22-29 age bracket

Then, the number of people that are in the 18-21 age bracket or agreed to respond is

69 + 12 + 282 = 363

Therefore, the probability of getting someone in the 18-21 age bracket or someone who agreed to respond is

P = 363/382

P = 0.9502

P = 95.0 %

Find angle B. What is angle B.

julsineya [31]

Answer:

B=45 Degrees

Step-by-step explanation:

You can use law of sines to answer. Law of Sines states that $\frac{sin(a)}{A} =\frac{sin(b)}{B}$ . That means that $\frac{sin(60)}{4\sqrt{6} }=\frac{sin(b)}{8}$ . Multiplying 8 to both sides gives us $\frac{8sin(60)}{4\sqrt{6} }=sin(b)$ . By using inverse of sin, we get $b = sin^{-1} (\frac{8sin(60)}{4\sqrt{6} } )$ . Plugging that into a calculator gives us b=45 degrees.
