Actually providing the diagram would be useful. Also, distinguishing between upper and lower case would also be useful. But given the convention that angles and the opposite side of the triangle are both given the same letter, but different case, I will assume that angle Q is opposite side q and that you have a situation of SAS. So using the law of cosines we have:
c^2 = a^2 + b^2 - 2ab cos C
Substitute the known values:
c^2 = a^2 + b^2 - 2ab cos C
c^2 = 20^2 + 30^2 - 2*20*30*cos 15
c^2 = 400 + 900 - 1200*0.965925826
c^2 = 400 + 900 - 1159.110992
c^2 = 140.8890085
c = 11.86966758
Rounded to the nearest tenth, gives 11.9</span>
The number that describes 0.9 repeating would be 3
It takes 10 1/10ths to make a minute so you have to take 1/7 times 10 and you get 10/7. Now divide 10 by 7 and you get 1 3/7 of an apple per minute.
The correct answer is that the angles created are equal.
The steps given are used to create an angle bisector of the angle. That means it divides the angle into 2 congruent angles.
For location 1:Probability of success = 0.5
Probability of failure = 1 - Probability of success = 0.5
Expected Value for Location 1 will be:
For location 2:Probability of success = 0.75
Probability of failure = 1 - 0.75 = 0.25
So, expected value for Location 2 will be:
The expected value from Location 2 is larger than Location 1, so Location 2 must be used to open up a bakery.
