You are constructing a 90% confidence interval for a sample consisting of n = 9 values and an unknown population standard deviation. The population appears to be very skewed. Determine
whether a margin of error should be calculated using a critical value of za/2, a critical value of
ta/2, or neither.

5x + 2 = 12 solve the following equation. then place the correct number in the box provided.

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41

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)
