Asample of =25n=25 diners at a local restaurant had a mean lunch bill of $16 with a standard deviation of =$4σ=$4 . we obtain a 95% confidence interval as (14.43,17.57)(14.43,17.57) . which action will not reduce the margin of error? increasing the number of digits for calculating the interval decreasing the confidence level decreasing the sample size sampling from a population with less variability

Algebra 1: unit 6 part 2 of test a) the table shows a linear function. x 0 1 2 3 5 13 21 29 37 45 53 (a) determine the difference of outputs of any two inputs that are 1 unit apart. show your work. (b) determine the difference of outputs of any two inputs that are 2 units apart. show your work.

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie

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)
