Answer:
91.30% probability that they have followed the professor's study recommendation
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Student earned a C or better.
Event B: Student followed the professor's study recommendation.
70% of the students are following this recommendation.
This means that
A statistics professor has found that a student who studies 90 minutes each day has a probability of .9 of getting a grade of C or better
This means that
Probability of earning C or better.
90% of 70%(those who followed the study recommendations).
20% of 30%(those who did not follow the study recommendations. So
Find the probability that, if a student has earned a C or better, that they have followed the professor's study recommendation:
91.30% probability that they have followed the professor's study recommendation
Two fractions are said to be equivalent if both the numerator and the numerator of one fraction can be obtained by multiplying or dividing the numerat.or and denominator of the other fraction by a single factor.
Dividing the numerator and denominator of 240/300 by 5 gives 48/60
Dividing the numerator and denominator of 240/300 by 60 gives 4/5
Dividing the numerator and denominator of 240/300 by 10 gives 24/30
Whereas dividing 300 by 2 gives 150 dividing 240 by 2 will not give 122. so 122/150 is not equivalent to 240/300.
Answer:
104
Step-by-step explanation:
X= 1/2 or x = 3/2.
Step 1: factor left side of equation. (2x-1)(2x-3)=O
Step 2: Set factors equal to 0. 2x-1=0 or 2x-3=0
X= 1/2 or x = 3/2.
