2n^2 + 4n + 2 = 0
Divide both sides by 2:
n^2 + 2n + 1 = 0
Find two numbers that multiply to form C (1) and add together to form 2: these numbers are 1 and 1:
(n +1)(n+1) = 0
(n+1)^2 = 0
Therefore n+1 = 0
n = -1
All of them are equal to 6 grams except for 60 kilograms (60 kg)
Answer:
a) 0.923
b) 0.957
c) 0.88
d) 0.077
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 40
Standard Deviation, σ = 14
We are given that the distribution of number of milligrams of porphyritic per deciliter of blood is a bell shaped distribution that is a normal distribution.
Formula:
a) P(xis less than 60)
P(x < 60)
Calculation the value from standard normal z table, we have,
b) P(x is greater than 16)
Calculating the value from the standard normal table we have,
c)P(x is between 16 and 60)
d) P(x is more than 60)
P(x > 60) = 1 - P(x < 60) = 1 - 0.923 = 0.077
