Use the quadratic polynomial 3x2−3x−90 to answer the questions.
a: which summary correctly applies the fundamental theorem to the quadratic polynomial?
b: which statement correctly verifies the application of the fundamental theorem of algebra?
select one answer for question a, and select one answer for question b.
b: the quadratic equation 3x2−3x−90=0 has two real solutions, x=6 or x=−5, and therefore has two real roots.
b: the quadratic equation 3x2−3x−90=0 has one real solution, x=5, and therefore has one real root with a multiplicity of 2.
b: the quadratic equation 3x2−3x−90=0 has two real solutions, x=−6 or x=5, and therefore has two real roots.
a: this polynomial has a degree of 2, so the equation 3x2−3x−90=0 has more than two roots.
a: this polynomial has a degree of 2, so the equation 3x2−3x−90=0 has exactly two roots.
a: this polynomial has a degree of 2, so the equation 3x2−3x−90=0 has two or fewer roots.

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
