The heights of the peach trees in an orchard are normally distributed with a mean of 12.5 feet and a standard deviation of 1.8 f
2 answers:
Mean = μ = 12.5
Standard deviation = σ = 1.8
z-score = - 0.5
Let the height of the Peach tree be x
Formula for Z -score = z =
Crossy multiply
z(σ) = x - μ
To find x add +μ on both sides
x = μ + z-score(σ)
x = 12.5 + (-0.5)(1.8)
x = 12.5 + (-0.9)
x= 12.5 - 0.9
x= 11.6 feet
So, the height of the Peach tree is 11.6 feet

Equivalent/Equal ratios<em> - Definition of Equivalent Ratio A ratio can be represented as a fraction. The concept of an equivalent ratio is similar to the concept of equivalent fractions. A ratio that we get either by multiplying or dividing by the same number, other than zero, to the antecedent and the consequent of a ratio is called an equivalent ratio.</em>
