The points (2.1, -4.2) and (2.5, -5) form a proportional relationship. What is the slope of the line that passes through these two points?Now, with the slope, write an equation for this relationship.

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

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76

If on=8x-8,lm=7x+4,nm=x-5,and ol=3y-6
