What are the two requirements for a discrete probability distribution? Choose the correct answer below. Select all that apply. A. Summation from nothing to nothing Upper P (x )equals 1 B. 0 less than or equals Upper P (x )less than or equals 1 C. Summation from nothing to nothing Upper P (x )equals 0 D. 0 less than Upper P (x )less than 1

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

b

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
