Answer/Step-by-step explanation:
The diagram of the circular track is missing, and so also its dimensions.
However, let's assume the dimensions of the circular track given is diameter (d) = 20 meters or radius (r) = 10 meters.
Since it's a circular track, the circumference of the track would give us the number of meters she runs in 1 lap.
Circumference = πd
d = 20 m (we are assuming the diameter is 20 meters)
π = 3.14
Circumference of circular track = 3.14 × 20 = 62.8 m.
This means that 1 lap = 62.8 m that she would have to run.
Therefore,
6 laps would be = 6 × 62.8 = 376.8 m
Therefore, if she completes 6 laps around the circular track that has a diameter of 20 m, she will have to run about 376.8 m.

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
4+4 is 8 so 4+5 is 9.So the strategy is a double +1. That is the strategy.
