You pick a card from a deck. If it is a face card, you will win 500. If you get an ace, you will win 1000. If the card you picked is red you get 100. For any other card, you will win nothing. Find the expected value that you can possibly win
Find the area of the region bounded by the curves x=y³ and y=x².
The mean serum level measured in 12 patients twenty-four hours after they received a newly recommended antibiotic was 1.2 mg/dl with a standard deviation of 0.4 mg/dl. If the mean serum level in the general population is 1.0 mg/dl, test whether or not the mean serum level in the sample group is significantly different from that of the general population. Use a = 5%. Compute the test value.
Let f : R → R be defined by f(x) = 3√(1 – x 3 ). a. Prove that f is bijective b. Determine f -1 (x)
An RCL circuit connected in series has R = 10 ohms, C = 10^2 farad, L = 1.5 henry, and an applied voltage E = 12 volts. Assuming no initial current and no initial charge at t = 0 when the voltage is first applied, find the subsequent current in the system.
A random sample of n = 13 is taken with a sigma ^ 2 = 5 Using two-tailed test, test the hypothesis with alpha = 0.05 that the s² = 3.6.
