Solve the following problems by using the binomial formula. a. If n = 4 and p = 0.50, find P(x = 3). b. If n = 7 and p = 0.70, find P(x = 4). c. If n = 10 and p = 0.60, find P(x ≥ 7). d. If n = 12 and p = 0.45, find P(5 ≤ x ≤ 7).
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
