Answer:
Yes, there are exactly 2 ways to solve this triangle.
Step-by-step explanation:
Well we know that to find out a trigonometric ratio we are given an angle and a side, and we have to solve for the other side. In this case only 2 of the legs are given, hypotenuse is neither given nor asked. So we have to use the ratio that doesn't have hypotenuse included. Tangent is the only such ration. Now we can use either Tan(51) or Tan(39) to solve for the "x".
These would be the functions to solve for x:
1.) Tan(51) =
2.) Tan (39) =
Hope this helps!
Answer:
Option b) 0.161
Step-by-step explanation:
We are given the following information:
We treat correct as a success.
P(Correct Answer) = = 0.2
Then the number of questions follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 11
We have to evaluate:
P(answer at least 4 questions correctly)
Thus, 0.161 is the probability that Richard will answer at least 4 questions correctly.
Option b) 0.161
