Find the equation of a line that passes though the point (4, -3) and is perpendicular to the line 6x - 3y= 4.

bearing in mind that perpendicular lines have negative reciprocal slopes, hmmm what's the slope of the equation above anyway?

so, we're really looking for the equation of a line whose slope is -1/2 and runs through (4,-3).

-1, -2, -3, -4, -6

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
