Medical: Blood Protoplasm Porphyrin is a pigment in blood protoplasm and other body uids that is signicant in body energy and storage. Let x be a random variable that represents the number of milligrams of porphyrin per deciliter of blood. In healthy adults, x is approximately normally distributed with mean μ = 41 and standard deviation σ = 9. What is the probability thata) x is less than 55?

0.9401 is the required probability.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 41

Standard Deviation, σ = 9

We are given that the distribution of number of milligrams of porphyrin is a bell shaped distribution that is a normal distribution.

Formula:

P(x is less than  55)

Calculation the value from standard normal z table, we have,  

0.9401 is the probability that x is less than 55.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
