A submarine travels 8.3 km due East from its base and then turns and travels due North for 11.9 km. How far away is the submarine from its base? Give your answer rounded to 1 DP.

two data sets with the same median will not have the same varaibility

step-by-step explanation:

may i see the picture? it would a lot, xox

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
