Consider a binomial experiment with n = 20 and p = .70.

a. Compute f(12) (to 4 decimals).

b. Compute f(16) (to 4 decimals).

c. Compute P(x 16) (to 4 decimals).

d. Compute P(x 15) (to 4 decimals).

e. Compute E(x).

f. Compute Var(x) (to 1 decimal) and (to 2 decimals).

Var(x)

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
