Harrizon [31]3 years ago
4 0

Answer:

The answer is 100%

Explanation:

we are given the mean which is $78 which is the average value of the data therefore this tells us most values are collectively around this bill and we also know the standard deviation of the cellphone bill which is $10 now we check the possibilities of x which is the cellphone bill being around these values so if x>$78+$10 , where x>$88 as we know the standard deviation is the measure of dispersion of data from the mean then we will see if x<$68 also then we'll find the probability where $68>x>$88 therefore if we sum these whole probabilities they will give us 1 which means it is certain but not impossible to find values that are $102>x>$54 which we see by the above numbers that approximately 1 is the probability which is 100%.

liubo4ka [24]

No, because the decision has already been made by the Board of Directors.

More about directors and decision making:

The board's decision-making process is divided into two stages: communication and decision-making. Each director decides whether to incur a cost to communicate his information to others during the communication stage. At the decision-making stage, all directors take actions (e.g., vote) based on their private information and information inferred from the discussion, and the board makes a collective decision. Directors may have conflicts of interest and thus prefer a decision that is not in the best interests of the shareholders. Directors may also have a preference for conformity and thus incur a loss if their actions differ from those of other directors, such as voting differently than the majority.

Managerial economist estimates the price-quantity relationship for Textile Company to be p= 40-4q a. At what output rate demand
Sindrei [870]

Answer:

So unit elastic at q = 5

inelastic above 5

and elastic below 5

Explanation:

The elasticity is determianted by the marginal revenue.

Our first goal is to find the marginal revenue function

p = 40 - 4q

total revenue(TR)  =  quantity times price

q x (40 - 4q) = -4q^2 +40q

marginal revenue TR(q)/d(q)  = -8q + 40

Now, with this fuction the economic analisys states that a demand is unit elastic when marginal revenue is zero.

It will be inelastic below zero and elastic above zero

MR will be zero when q = 5

-8(5) + 40 = 0

As quantity increases the demand will be inelastic
