Step-by-step explanation:
Solution: We are given that the grade point average of undergraduate students at one university have a normal distribution, with mean, standard deviation,
We have to find the percentage of the students whose grade point averages are no more than 3.36, i.e., P(x<3.36).
We need to first find the z-score.
Now we have to find . Using the empirical rule, we know that 97.5% data lies below 2 standard deviations above mean.
Therefore, using the empirical rule, 97.5% of the students have grade point averages that are no more than 3.36.
B because the answer is B
9 student because if each row holds nine then the last row must hold nine
Since we have reflected only across the y-axis we know the x-values stay the same (but since they are changing quadrants will become positive) and the same goes for the y-values. Only the negative/positive area will change. Lets get to work:
<em>P(-2, -4) will become P'(2, -4)</em>
<em>Q(-3, -1) will become Q'(3, -1)</em>
<em>R(-4, -4) will become R'(4, -4)</em>
After doing this for a while you will be able to find the reflected coordinates without any trouble or graph.
