Step-by-step explanation:
it's 100% right
This is the concept of statistics, to solve the question we proceed as follows;
We need to standardize our values;
z(3,875)=(3,875-4000)/42
z(3,875)=-2.9762
z(4055)=(4055-4000)/42=1.3095=1.3
Therefore;
p(3875<x<4055)
=p(-3<z<1)
=0.9034
The correct answer is D]
X would be square root of 10 because u would do properties
NOT a function ......................... :)
