The coordinates of the point P given by mean the point P is
at a distance horizontally in the positive x-direction if
and at a distance
horizontally in the negative x-direction if
.
Also, point P is at a distance horizontally in the positive y-direction if
and at a distance
horizontally in the negative y-direction if
.
Hence the point with coordinates is 4 units horizontally in the positive x-direction and 2 units vertically in the negative y-direction. So the point is is H. Correct choice is (2).
Answer:
(1) The correct option is (A).
(2) The probability that Aadi will get Tails is .
Step-by-step explanation:
It is provided that:
- Eric throws a biased coin 10 times. He gets 3 tails.
- Sue throw the same coin 50 times. She gets 20 tails.
The probability of tail in both cases is:
(1)
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
In this case we need to compute the proportion of tails.
Then according to the Central limit theorem, Sue's estimate is best because she throws it <em>n = </em>50 > 30 times.
Thus, the correct option is (A).
(2)
As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:
Thus, the probability that Aadi will get Tails is .
