Brilliant_brown [7]

Answer:

Step-by-step explanation:

First, the profit formula:

PROFIT= TOTAL REVENUE - TOTAL COST

Next, note the points:

- Without Advertisement, Q = 6,000 where Q is quantity supplied

- A formula that gives the total profit P in dollars must take into account that 100cents = 1dollar

- Here, only a dollar is spent on advertisement, hence, Q = 6005

- Advertising expenses have been accounted for and [P = 9cents × Q] where Q is quantity sold.

- 9 cents = 0.09 dollars

TOTAL PROFIT FORMULA = 0.09Q - 500

Naily [24]

Answer:

The expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.

Step-by-step explanation:

The data provided is:

                                                   Opinion    

Front Footage   For       Undecided Against    Total

Under 45 feet    12                4              4              20

  45-120 feet           35                5             30      70

Over 120 feet     3                2              5              10

       Total           50                11             39    100

The formula to compute the expected frequency is:

E(X)=\frac{\text{Row Total}\times \text{Column Total}}{\text{TOTAL}}

Compute the expected frequency for people against the project and who have over 120 feet of property foot frontage as follows:

E(X)=\frac{\text{Row Total}\times \text{Column Total}}{\text{TOTAL}}

E(5)=\frac{10\times 39}{100}=\frac{39}{10}=3.9

Thus, the expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
