The weight of a small Starbucks coffee is a normally distributed random variable with a mean of 410 grams and a standard deviation of 10 grams. Find the weight that corresponds to each event highest 30%, middle 70% to x, lowest 90%, lowest 20%

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

you need to give us more information since we can't answer

you can use a^2+ b^2=c^2
