Answer:
32 cm is the length of PQ ans
Answer:
0.9209
Explanation:
For a normally distributed random variable, the only way to find areas is using the z score. The z score is given by the equation:

Where μ is the mean, σ is the standard deviation and x is the raw score to be measured.
The area under the standard normal curve that lies between the interval z=-2.73 and z=-1.39
From the z table, Area between -2.73 and -1.39 = P(z < -1.39) - P(z < -2.73) = 0.0823 - 0.0032 = 0.0791
Since the Area between -2.73 and -1.39 is 0.0791, the are outside the interval = 1 - 0.0791 = 0.9209
That is a very good score! Don’t be disappointed. It’s okay to retake the SAT if you are not happy with the score. Most colleges take your highest score anyways. Good job!
