Answer:
35.5 cm
Step-by-step explanation:
The perimeter (P) is calculated as
P = (2 × 6.75 ) + (2 × )
= 13.5 + (2 × 11) = 13.5 + 22 = 35.5 cm

The answer is 96%.
Explanation:
It is generally presumed that the scores are normally distributed.
1) You are given how many standard deviations from the mean Jeremy's score is. This is exactly the definition of the z-score. Therefore z = 1.75
2) Look at a left-tail z-table in order to find the area of the normal curve on the left of your z-score (see picture attached). A = 0.9599
3) Multiply the area by 100 in order to find the percentile:
<span>0.9599 </span>× 100 = 95.99
Therefore, 95.99% of the students scored less than Jeremy.
Hence, the answer is 96%.
