Answer:
The answer is below.
Explanation:
The z score is a used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

a) Given that n = 100, μ = 2000, σ = 18
For x < 1995 millimeters:

From the normal distribution table, P(x < 1995) = P(z < -2.78) = 0.0027
b) P(z > z*) = 10% = 0.1
P(z < z*) = 1 - 0.1 = 0.9
z* = 1.28

From the normal distribution table, P(z < z
The percentage of the money given to practitioner is called "commission"
Answer:
x =
or 
Explanation:
The cardboard box is in the shape of a cube. The surface area of the box is given by:
S = 6
To find the inverse, we have to solve for x. To solve for x means we will make x the subject of the equation above
Divide both the right and left hand side by 6, we have:
6
÷ 6 = S ÷ 6 ⇒
=
=
Take the square root for both the right and left hand side, we have:
=
⇒ x =
x =
or 
Therefore, x is equivalent to the square root of (S/6)

Explanation:
In this respect, we need to calculate the discount factor of annual cash inflows for 12 years at 14 discount rate. For this purpose, present value annuity interest factor will be used since the cash inflows are constant. Then, we will multiply the annual cashflows by the discount factor so as to obtain the present value of cash inflows. Then, we will deduct the initial outlay from the present value of cash inflows in order to obtain the net present value of the proposal.
