An astronaut on the moon throws a baseball upward with an intial velocity of 10 meters per second, letting go of the baseball 2 meters above the ground. The equation of the of the baseball pathway can be modeled by h= =0.8t^2 + 10t+2. The same experiment is done on earth , in which the pathway is modeled by equatoin h=-4.9t^2+10t+2. How much longer would the ball stay in the air on the moon compared to on earth.

What is the value of the expression below? 148+(-6)| + |– 35= 7|

Simplify (2^5/3^2)^4 a. 2^20/3^8 b. 2^9/3^8 c. 8^5/12^2 d. 2/3^2

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
