Imran and Aubrey were asked to find an explicit formula for the sequence 14,5,-4,-13,...14,5,−4,−13,...14, comma, 5, comma, minus, 4, comma, minus, 13, comma, point, point, point, where the first term should be g(1)g(1)g, left parenthesis, 1, right parenthesis. Imran said the formula is g(n)=14-9(n-1)g(n)=14−9(n−1)g, left parenthesis, n, right parenthesis, equals, 14, minus, 9, left parenthesis, n, minus, 1, right parenthesis.
Aubrey said the formula is g(n)=14-9ng(n)=14−9ng, left parenthesis, n, right parenthesis, equals, 14, minus, 9, n.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?

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
