z=(63-84)/3= -21/7= -3
P(x>63)=p(z > -3) = .9987 or 99.87%
This function would have a maximum.
Since we are subtracting by a -4 for each increase in x, we know that the numbers will continue to go down. Given this fact, we know the number will never be higher than when we started, but the number could go infinitely low. As a result we have a maximum and no minimum.
The question is "What is the scale of the model to the actual statue"
That means you must put 2/15.
2 being the model
15 being the actual statue
Take that fraction and equal is to 1/x.
Multiply 15 to 1 and 2 to x.
In the end, to solve, you divide 15 by 2x.
The answer is X=7.5
1 : 7.5
I'm not 100% sure this is right but I think this is how you do it
