The table of values below represent an exponential function. Write an exponential equation that models the data. x y
-2 26
-1 18.2
0 12.74
1 8.918
2 6.2426

a. y=18.2(1.7)^x
b. y=12.74(1.3)^x
c. y=26(0.7)^x
d. y=12.74(0.7)^x

Asimple random sample of size nequals14 is drawn from a population that is normally distributed. the sample mean is found to be x overbar equals 70 and the sample standard deviation is found to be sequals13. construct a 90% confidence interval about the population mean

Can (3,5 and square root 34) be sides on a right triangle?

What is the average rate of change for this function for the interval from x=2 to x=4 ?
