What is the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1)?
these are the options
x2 + (y + 4)² = StartRoot 5 EndRoot
(x – 1)² + (y + 2)² = 5
(x + 4)² + y² = 5
(x + 2)² + (y – 1)² = StartRoot 5 EndRoot

What can each term of the equation be multiplied by to eliminate the fractions before solving? x – + 2x = + x 2 6 10 12

The product of sin 30 degrees and sin 60 degrees is same as the product of

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
