Answer:
The mean score is 7.31. This means that each time the student takes this test, he is expected to get a score of 7.31.
Step-by-step explanation:
We have these following probabilities:
A 0.07 = 7% probability that the student scores 5 points.
A 0.17 = 17% probability that the student scores 6 points.
A 0.38 = 38% probability that the student scores 7 points.
A 0.21 = 21% probability that the student scores 8 points.
A 0.1 = 10% probability that the student scores 9 points.
A 0.07 = 7% probability that the student scores 10 points.
Mean score
We multiply each score by it's probability. So
The mean score is 7.31. This means that each time the student takes this test, he is expected to get a score of 7.31.
The answer I believe is the second one to the top
Answer/Step-by-step explanation:
The question didn't specify which of the numbered angle we're to look for. However, let's find all the numbered angles.
✔️m<2 = 180° - 53° (linear pair angles)
m<2 = 127°
✔️m<7 = 180° - 53° (consecutive exterior angles are supplematry)
m<7 = 127°
✔️m<8 = 53° (alternate exterior angles are congruent)
