Answer:

Events departing on time and arriving on time are NOT independent.

Explanation:

If two events A and B are independent, then

P(A and B) = P(A) * P(B)

Here

A = flights depart on time

B = flights arrive on time

P(A) = 0.90

P(B) = 0.80

If A and B are independent, then

P(A and B) = P(A) * P(B) = 0.9 * 0.8 = 0.72

Since

the observed value of P(A and B) is 0.75,

assuming that there are no observation errors, we conclude that the two events A and B are not independent.

A flower vendor sells roses for 50 cents each. how much does she pay per flower if she makes $6.00 on every twenty dollars worth
Bess [88]
Let $x = the cost per flower.

Number of roses sold = 20
Profit on 20 roses = $6

Cost = (30 roses)($x per rose) = $ 20x
Revenue = ($0.50 per rose)*(20 roses) = $10
Profit = $10 - $ 20x = $6

That is,
10 - 20x = 6
20x = 10 - 6
20x = 4
x = $0.2 = 20 cents

Answer: She paid 20 cents per flower.

Cesar claims he found a definite way to save money, "Buy direct from the manufacturer. Any time intermediaries get involved, you
Anni [7]

Answer:

Explanation:

Great question, intermediaries are sometimes necessary since they provide a service in which you might not be able to get the product if their service wasn't provided. That being said we can say that Caesar's claim is not valid in many cases. Intermediaries tend to add an additional cost to a certain product, but like mentioned above they are providing an essential value. In many cases the value they create more than offsets the costs they add. Therefore the validity of Caesar's claim is dependent on the intermediaries provided value.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

jonny [76]
<span>The current state of the US economy is in growing strength with respects to the former cabinet. Globalization is affecting the US economy. Primarily through technology and social feeds. We are in the information Era. As far as jobs, off shoring in our economy was once always a viable option. Now that we have a president who insists on the "American Made" branding has emboldened some companies to minimize their operations abroad and increase facilities at home. I work on software, and my job requires me to be in a wireless world. It is hard to compete with companies who hire third party IT hosts in other countries because it is simply cheaper. But, I find other means for work.</span>
