Answer:
0.0139
Explanation:
Given that:
The number of sample (n) = 21
The sample distribution has mean (μ) and a standard deviation of σ/√n
The z score is given as (x - mean)/ standard deviation
x = 94.8 wpm, let us assume that σ = 10 and μ = 90
Therefore: z = (x - μ) / (σ/√n) = (94.8 - 90) / (10/√21) = 2.2
To calculate the probability using Z table:
P(X>94.8) = P(Z>94.8) = 1 - P(Z<94.8) = 1 - 0.9861 = 0.0139
The probability is low that is less than 0.05, the program is more effective than the old one.
Answer:
False
Explanation:
Variable costs are part of direct expenses incurred in the production of goods meant for sales. Variable costs have a direct and proportionate relationship with the output level. An increase in output level increases variable costs. Examples of variable costs are packaging and raw materials.
The contribution margin is the dollar amount available from the sale of each unit to cater for fixed costs and profits. It is calculated by subtracting variable costs from the selling price. The contribution margin is used in determining the break-even point and the output level required to achieve desired profits.

Answer: I must invest <u>$85424.14</u> today in order to buy a Ferrari nine years from now on the day I turn 30.
We have
Price of the Ferrari nine years from now (Future Value - FV) $215000
Expected Rate of return on the mutual fund (r) 10.8%
Time until I turn 30 (n) 9 years
We can calculate the Present Value (PV) or the money to be invested today as
