A psychology professor assigns letter grades on a test according to the following scheme. A: Top 15%15% of scores B: Scores below the top 15%15% and above the bottom 60%60% C: Scores below the top 40%40% and above the bottom 15%15% D: Scores below the top 85%85% and above the bottom 8%8% F: Bottom 8%8% of scores Scores on the test are normally distributed with a mean of 71.971.9 and a standard deviation of 7.57.5. Find the minimum score required for an A grade. Round your answer to the nearest whole number, if necessary.

D: Scores below the top 85%85% and above the bottom 8%8% F: Bottom 8%8% of scores Scores on the test are normally distributed with a mean of 71.971.9 and a standard deviation of 7.57.5.

Step-by-step explanation:

6   llegue

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
