A plane is missing and it is presumed that it was equally likely to have gone down in any of the 3 possible regions. If the plane is in region 1, it will be found with probability 0.70. If the plane is in region 2, it will be found with probability 0.40. And, if the plane is in region 3, it will be found with probability 0.30. What is the probability that during a search, the plane is not found in region 1?

It is easier to create a probability table.

FOUND NOT FOUND TOTAL

REGION 1 0.70 0.30 1

REGION 2 0.40 0.60 1

REGION 3 0.30 0.70 1

The probability that during the search, the plane is not found in region 1 is 0.30. (1 - 0.70)

FOUND NOT FOUND TOTAL

REGION 1 0.70 0.30 1

REGION 2 0.40 0.60 1

REGION 3 0.30 0.70 1

The probability that during the search, the plane is not found in region 1 is 0.30. (1 - 0.70)

Where in the world may a person walk one mile west, and then one mile north and arrive back at the starting point

Answer:

North Pole

Step-by-step explanation:

Answer:

So your walk of 1 mile West is a complete circle. You then walk 1 mile North, which brings you back to your starting point, (1 + 1/(2pi)) miles from the South Pole. The obvious answer is the North Pole. You're either on the North Pole, or somewhere very near (about 840 feet or less) the South Pole.-step explanation:

The equation yˆ=105.416x+1249.309 models the amount of money, in dollars, a charity raises during an annual event when x people attend the charity dinner. what does the y-intercept of the equation represent in context of the situation? it costs the charity $1250 to host the dinner. it costs the charity $105 to host the dinner. if no one came to the dinner, the charity would still raise about $1250. if no one came to the dinner, the charity would still raise about $105.

If no one came to the dinner, the charity would still raise about $1250.

Answer:

If no one came to the dinner, the charity would still raise about $1250.
