Answer:
B. The elasticity of demand is -0.126
Explanation:
% Change in Quality demand = -2.65% (this is negative because of drop in prenatal smoking)
% Change in price = 21%
Elasticity of demand is given by the formula below:
Elasticity of demand = % change in quantity demanded ÷ %change in price
Elasticity of demand = -2.65 / 21
Elasticity of demand = -0.126
Answer:
n = 150.06
Explanation:
Since the confidence c = 95% = 0.95
α = 1 - 0.95 = 0.05
z score of 0.025 is the same as the z score of 0.5 - 0.025 = 0.475
From the probability table, 
Also E = 0.08
Therefore the sample size n is given by:
n = 150.06
The sample must be at least 150.06 to be 95% sure that a point estimate will be within a distance of 0.08 from p
Answer:
a. is the change in total satisfaction derived from consuming one more unit of a good.
Explanation:
Marginal utility: It defines as changes in total satisfaction of consumers with one additional unit changes in the consumption of goods. It derives satisfaction level of consumer with the units of goods consumed, similarly usage of product changes with the number of the product we have in stock or purchased.
Formula; Marginal utility= 
There are several types of marginal utility:
- Zero marginal utility.
- Positive marginal utility.
- Negative marginal utility.
- Increasing marginal utility.
- Diminishing marginal utility.
Answer:
The amount of net cash flow from investing activities that ion should report in its cash flow statement is $65,000.
Explanation:
A cash flow statement is one of the financial statements which will tell how changes in income statement and balance sheet accounts will affect the company's cash inflow and outflow. This statement will break down the analysis in to operating , investing and financing activities.
For taking out the net cash flow in investing activities, purchase activities are added and sale activities are subtracted and from the given information in the question , it is clear that both are purchasing activities, therefore
NET CASH FLOW FROM INVESTING = $25,000 + $40,000
= $65,000
Answer:
The forecast for September using exponential smoothing with alpha = 0.4 is 62.
Explanation:
Forecasting Formula
Forecasting the next point is determined using the forecasting formula is the basic equation
S(t+1)=αy(t)+(1−α)S(t), 0<α≤1,t>0.
α = alpha =0.4
New forecast S(t+1) is previous forecast S(t) plus an error adjustment. This can be written as:
S(t+1)=S(t)+αϵ(t),
where ϵ(t) is the forecast error (actual - forecast) for period t.
In other words, the new forecast is the old one plus an adjustment for the error that occurred in the last forecast.
New forecast for August S(t+1) = 0.4×60 + (1-0.4)×70
= 66
New forecast for September S(t+1) =0.4×56 + (1-0.4)×66
=62
