Answer: a) 0.04667544
b) 0.01129221
c) 0.98870779
Explanation:
Binomial probability formula :-
, where P(x) is the probability of getting success in x trials, n is the total number of trials and p is the probability of getting success in each trial.
Given : The probability of households say they would feel secure if they had $50,000 in savings = 0.30
Total number of households selected = 8
a) The probability that the number that say they would feel secure is exactly five will be :-
b) The probability that the number that say they would feel secure is more than five :-
c) The probability that the number that say they would feel secure is at most five :-
Agatha's weekly allowance is 36.
<h3>What is the cost of the fidgets?</h3>
If she can afford to purchase both four fidgets and three candy bars and nine candy bars and two fidgets, it means that the cost of both options are the same.
4f + 3c = 2f + 9c
Where:
f = cost of one fidget
c = cost of one candy bar
4f + 3(2.40) = 2f + 9(2.40)
4f + 7.2 = 2f + 21.6
4f - 2f = 21.6 - 7.2
2f = 14.4
f = 14.4 / 2
f = $7.20
<h3>What is Agatha's weekly allowance?</h3>
Weekly allowance = 4f + 3c
4(7.2) + 3(2.4)
28.8 + 7.2 = $36

Answer:
a small alpha value is used.
Explanation:
The exponential smoothing forecasting technique is used for forecasting a time series when there is no trend or seasonal pattern, but the mean of the time series is slowly changing over time.
The choice of the smoothing constant α (alpha) is important in determining the operating characteristics of exponential smoothing. The smaller the value of α (alpha), the slower the response. Therefore when a small alpha value is used the exponential smoothing forecasting technique slowly responds to changes in the mean level of demand.
When the values of α (alpha) are larger this makes the smoothed value to react quickly – not only to real changes but also random fluctuations.
Answer:
The correct answer is a. an increase in the money supply lowers the equilibrium rate of interest.
Explanation:
The preference for liquidity is a recurring expression in the study of economics, especially important in Keynesian theory and which assumes that people consider it better to have their savings in liquid form, that is, as money.
This concept, very recurrent in macroeconomics, assumes the existence of an outstanding trend in human and rational behavior whereby individuals prefer to have their assets in an accessible and liquid way compared to other possibilities. Originally, the definition of liquidity preference was coined by Keynes when explaining the concept of monetary demand and its mode of action.
This theory suggests that there is a direct relationship between interest rates or rates and people's preferences in terms of liquidity, since both keeping money effectively and not doing so carry certain costs for them. In other words, saving money can translate into financial gain.
For Keynes, there were three reasons why the individuals who make up the money demand opt for liquidity and money: transactions, caution and speculation.
