The post office is at the corner of first street and main street, which forms a right angle. first street intersects with oak street to the north, and main street intersects with oak street to the east. the intersection of main street and oak street forms a y° angle, and tan y° = 5/7. car a drives on main street for 14 miles to arrive at oak street. how far will car b have to travel on first street to get to oak street? round your answer to the nearest tenth of a mile. a. 7.14 milesb. 14 milesc. 20 milesd. 28.14 miles

What is the remainder when 2872 is divided by 76? a) 51 b) 57 c) 60 d) 63

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cos of 61.6

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
