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%.

Answer:
See attached image for the requested graph
Step-by-step explanation:
The values completed in the table and text boxes as shown, are all correct.
For the plotting of the points and drawing of the line, please see the attached image.
Horizontal compression by factor 2 will do following.
After compression graph of the function is going to be closer to line of symmetry of the parabola. Values of y are not going to change, but values of x will be 2 times closer to the the line of symmetry.
For our case , line symmetry x=2,
points are going to be 2 times closer to this line.
1st point (4, -3) converts into (3,-3)
2nd point (-4,5) converts into (-1,5)
