Answer:
99.7%
Step-by-step explanation:
Note that 92 and 128 are 3 standard deviations from the mean
The emperical rule or the 68–95–99.7 rule states that 68% of outcomes are wihtin 1 standard deviation from the mean
95% of outcomes are within 2 standard deviations from the mean
99.7% of outcomes are within 3 standard devations from the mean
This is 3 standard deviations so the answer is 99.7
A direct variation has a constant slope, i.e. (y/x)= constant.
Both of the given two points give a slope of (y/x)=14/2=28/4=7, so the equation of the function is
y/x=7, or simply
y=7x
