Answer:
Short-response question = 20.
Step-by-step explanation:
Let x be number of short response questions and y be the number of essay questions.
We have been given that there are 22 questions that are worth 100 points in total. Each short-response question is worth 4 points, and each essay question is worth 10 points. Using our given information we can form a system of equations as:
Now we will solve our system of equations using substitution method.
From equation 1 we will get,
Upon substituting
in equation 2 we will get,




Therefore, there are 20 short-response questions on the exam.
If this is greater than the first part of the number called by the spectator (i.e., ignoring the last two digits), then the last digit of your answer is the lower of the two possible values. Otherwise the last digit is the higher value. For example if the number called is 2809, the square root could be either 53 or 57.
Answer:
c i think
Step-by-step explanation:
it's c i think
Given P(E) = 0.24 and P(F ∩ E) = 0.17
It says to find conditional probability of F given E has occurred.
We know the formula of conditional probability is given by :-
P(F ║ E) = 
P(F ║ E) =
= 0.708333
P(F ║ E) = 0.71
Hence, option C i.e. 0.71 is the final answer.
