Answer:
equation will be 2x+5
Explanation:
We have given the cost of shipping box = $5
Flat packing fee = $5
As given, the cost of shipping a box is based on its weight in pounds so it is variable
And a flat rate of $5 for packing. This means $5 is common for each parcel that will be sent. Only the weight will vary.
So the equation will be 2x+5
Answer:
Expected market return = 9.8%
Explanation:
The expected return on the market can be worked out using the Capital Asset Pricing Model.
<em>The capital asset pricing model is a risk-based model. Here, the return on equity is dependent on the level of reaction of the the equity to changes in the return on a market portfolio. These changes are captured as systematic risk. The magnitude by which a stock is affected by systematic risk is measured by beta.
</em>
Under CAPM, Ke= Rf + β(Rm-Rf)
Rf-risk-free rate (treasury bill rate)- 4.4%
β= Beta - 1.20
Rm= Return on market.- ?
Applying this model, we have
11%= 4.4%+ (R-4.4%)×1.20
0.11-0.044= 1.20×(R-0.04)
0.07
= 1.20R-0.048
Collect like terms
0.07+0.048 = 1.2R
Divide both sides by 1.20
R= (0.07+0.048)/1.20
R=9.83%
Expected market return = 9.8%
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.
