The U. S. Coast Guard maintains a database of the number, source, and location of oil spills in the U. S. navigable and territorial waters. The following is a probability distribution for location of oil spill events. Location Probability
Atlantic Ocean 0.011
Pacific Ocean 0.059
Gulf of Mexico 0.271
Great Lakes 0.018
Other Lakes 0.003
Rivers and canals 0.211
Bays and sounds 0.094
Harbors 0.099
Other 0.234

Explain why this probability assignment is legitimate from a probabilisticpoint of view. Determine the probability that an oil spill in U. S. navigable an territorial waters

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
