Answer:
Two dotted lines, one solid line
Step-by-step explanation:
The graph of the system of inequalities
will have two dotted lines, one solid line.
To plot the solution set to the inequality with signs < or >, we need to plot the dotted line (because the points of this line are not the solutions to the inequality).
To plot the solution set to the inequality with signs ≤ or ≥, we need to plot the solidd line (because the points of this line are the solutions to the inequality).
The system above has two inequalities with signs < and > and one inequality with sign ≥, so there will be two dotted lines, one solid line.
Step-by-step explanation:
The probability of success = 8/(8 + 17) = 8/25 = 0.32.
Let X be the random variable denoting the number of successes (number of times the individual won a prize) in four picks.
Hence, X ~ Bin(4, 0.32).
Thus, P(X = 1) =
The board is 0.666667 feet long.
The answer is B because they would have been 3 and 6.
