Answer:
0.6628 or 66.28%
Step-by-step explanation:
The probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old is determined by the probability of them being a white 16 to 17 years old dropout (5.7%), divided by the probability of them being a 16 to 17 years old dropout of any ethnicity (8.6%):
There is a 0.6628 or 66.28% chance that a randomly selected dropout is white, given that he or she is 16 to 17 years old.
Let the segment be represented by AB where A(0,0) = and B(3/4,9/10) =
.
The length of the segment drawn by architect can be calculated using distance formula:
AB =
Similarly, Let the actual end points of segment be AC where A(0,0) = and C(30,36) =
.
The length of the original segment can be calculated using distance formula:
AC =
.
Thus, the actual length is 40 times the length of the segment drawn by the architect.
Thus, the proportion of the model is 1:40
