You receive a prescription calling for 12% nystatin cream to be compounded. You have 15 grams of a 35% cream on hand as well as a 2% cream. Using the alligation method, how many grams of 2% cream should be added to the whole amount of 35% cream to prepare the final product? Round to the nearest tenth decimal place.

Write the equation of the line that contains the points (3,7) (-3,-3)

Player 1 writes an integer between 1 and 15 (including 1 and 15) on a slip of paper. Without showing this slip of paper to Player 2, Player 1 tells Player 2 what they have written. Player 1 may lie or tell the truth. Player 2 must then guess whether or not Player 1 has told the truth. If caught in a lie, Player 1 must pay $10 to Player 2; if falsely accused of lying, Player 1 collects $5 from Player 2. If Player 1 tells the truth and Player 2 guesses that Player 1 has told the truth, then Player 1 must pay $1 to Player 2. If Player 1 lies and Player 2 does not guess that Player 1 has lied, then Player 1 wins $5 from Player 2. Determine the von Neumann value of the game and optimal strategies for both players.

Studies show that about five women in seven (approximately 71.4%) who live to be 90 will develop breast cancer. Suppose that of those women who develop breast cancer, a test is negative 25% of the time. Also, suppose that in the general population of women, the test for breast cancer is negative about 45% of the time. Let B=women develops breast cancer, P=tests positive, and N=tests negative. Suppose one woman is selected at random. Round your answer to three decimal places. Given that a woman develops breast cancer, what is the probability that she tests positive. Find P(P|B) = 1-P(N|B). What is the probability that a woman develops breast cancer and tests positive. Find P(B AND P) = P(P|B)P(B). What is the probability that a woman does not develop breast cancer. Find P(B’) = 1-P(B). What is the probability that a woman tests positive for breast cancer. Find P(P)=1-P(N).
