Answer:
The fraction or percentage of the applicants that we would expect to have a score of 400 or above is 77.34%
Step-by-step explanation:
Scores are normally distributed with a mean of 460 and a standard deviation of 80. For a value x, the associated z-score is computed as , therefore, the z-score for 400 is given by . To compute the fraction of the applicants that we would expect to have a score of 400 or above, we should compute the probability P(Z > -0.75) = 0.7734, i.e., the fraction or percentage of the applicants that we would expect to have a score of 400 or above is 77.34%
Can u post the other part of the problem
7(x + 2) = 6(x + 5)
7x + 14 = 6x + 30
x + 14 = 30
x = 16
