The equation to find a z score is (x- mean)/(standard deviation)
So, in this case the equation would be
(76-70)/(2.1)
For,
X=76
Mean=70
Standard Deviation= 2.1
After solving we find that the z score equals 2.85714
or
2.8571
I gallon of water per 1 inch of fish
lemon tetra is 2 inches long
so 1 lemon tetra for 2 gallons of water
20/2 = 10
they can have 10 of them
equation would be X = 20/2
