If a person's temperature after x hours of strenuous exercise is t(x) = x3(7 − x2) + 98.6 degrees fahrenheit (for 0 ≤ x ≤ 2), find the rate of change of the temperature after 1 hour.

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

Solve the system. -a+4b+2c=-8 3a+b-4c=9 b=-1 a.(0,11) ,-1,2) c.(1,1,-2) d.(2,-1,-1)
