Answer:
200π
Step-by-step explanation:
Surface area is abbreviated to SA
TOTAL SA of cone = Base area + πrl
Base area = πr² = π x 8² = 64π
Curved SA = πrl = π x 8 x l
to work out l, use pythagoras theorem: √(15)² + (8)² = 17
so, curved SA = π x 8 x 17 = 136π
Total SA of cone = 64π + 136π = 200π
Answer:
E. The student scored 1.3 standard deviations lower on the second exam than the class average on the second exam.
Step-by-step explanation:
Whenever we have a negative z-score, this means that the raw score is a certain standard deviation below the mean average.
From the above question, we are told that:
An AP Statistics teacher grades using z-scores. On the second major exam of the grading period, a student receives a grade with a z-score of -1.3.
This means the students score in the second major exam is 1.3 standard deviations below the average score in the second major exam.
Hence, according to the options given in the above question, the correct interpretation of this grade is
The student scored 1.3 standard deviations lower on the second exam than the class average on the second exam.
Option E is the correct option.
