Answer: 1.25
Step-by-step explanation:
Given: A college-entrance exam is designed so that scores are normally distributed with a mean = 500 and a standard deviation
= 100.
A z-score measures how many standard deviations a given measurement deviates from the mean.
Let Y be a random variable that denotes the scores in the exam.
Formula for z-score =
Z-score =
⇒ Z-score =
⇒Z-score =1.25
Therefore , the required z-score = 1.25
Answer:
V = 929.7
Step-by-step explanation:
Given the equation:
=
The integral of the above equation is:
=
Re-organizing the integrals:
=
Integrating:
ln(CA) - ln(CA0) =
Inputting the initial conditions of CA and the values of k and V0:
ln(7) - ln(100) =
1.946 - 4.605 = -0.00286V
-2.659 = -0.00286V
=> V =
V = 929.720
Approximating to one decimal place,
V = 929.7
