Answer:
The z-score is 
The percentile is 
Step-by-step explanation:
From the question we are told that
The data value is 0.6 standard deviations above the mean i.e 
Where 
is the population mean and 
is the standard deviation
Generally the z-score is mathematically represented as
=> 
=>
The percentile is obtained from the z-table and the value is
=>
Answer:
xy=5
Step-by-step explanation:
from the question, y varies directly with x and y
Then y ∝ xy
If we introduce proportionality sign we have
y=r xy
Where r= proportionality constant
Then if we substitute the given values
y = 25 when r = 5.
We have
y=r xy
25=5xy
Divide both sides by 5
xy=25/5
xy=5
Hence, equation that models the statement is xy=5
