This is a very easy exercise, follow the steps taken below:
Step 1: Find
Note that If
then
Therefore,
Step 2: Find A⁻¹B ( i.e product of A and B)
Step 3: Decode the message in the matrix above
The message will be decoded in this order:
Note that 0 stands for empty space
19 5 3 18 5 20 0 1 7 5 14 20 0 13 1 14
S E C R E T A G E N T M A N
The message encoded is: S E C R E T A G E N T M A N
Answer:
The cutoff for an A grade is 82.8.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
a. What is the cutoff for an A grade?
The top 10% of the class get an A grade. So the cutoff is the value of X when Z has a pvalue of 1-0.1 = 0.9. So it is X when Z = 1.28
The cutoff for an A grade is 82.8.
