Use the z-distribution table on pages A-1 and A-2 or technology to solve. Suppose a set of data is normally distributed.

Below which z-score do approximately 34 of the data lie?

−0.68

−0.67

0.67

0.68

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
