A bin contains 3 types of flashlights (Type 1, Type 2, and Type 3.) The probability that a Type 1flashlight will give more than 100 hours of use is 0.7. The corresponding probabilities for Types 2 and 3are 0.4 and 0.3 respectively. Furthermore, assume that 20% of the bin contains Type 1 flashlights, 30% Type 2, and 50% Type 3 flashlights. (a) What is the probability that a randomly chosen flashlight will give more than 100 hours of use? (b) Given that a flashlight has lasted more than 100 hours, what is the probability that it was a Type 2 Flashlight?

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)

The standard deviation for a set of data is 5.5. the mean is 265. what is the margin of error?

Is the point (0, 8) on the x-axis or y-axis? how do you know?
