Assume that random guesses are made for nine multiple choice questions on an SAT test, so that there are nequals9 trials, each
with probability of success (correct) given by p equals 0.35. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4.

Answer:
3) 0.72
Step-by-step explanation:
The probability that tomorrow the Fed will cut interest rates (P(F)) OR the DJIA will go up (P(D)), is the sum of each event's individual probability minus their joint probability (Fed cutting interest rates AND the DJIA will going up, P(FD))
The probability that tomorrow the Fed will cut interest rates or the DJIA will go up is 0.72.
Given:
The point is (-12,-8).
Rule of transformation is .
To find:
The coordinates of image after transformation.
Solution:
According to the rule of transformation , first the point is dilated by factor
with origin as center of dilation after that it was rotated 270 degrees anticlockwise.
If a point is dilated by factor with origin as center of dilation, then
If a point is rotated 270 degrees anticlockwise, then
Therefore, the coordinates of image after transformation are (-2,3).
