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)
percentage - 25%
probability - 0.25
we know,
total amount of students in class = 20
total boys = 10
total girls = 10
no of girls who wear glasses = 10/2 = 5
probability of choosing a girl with glasses is =
number of girls wearing glasses/total number of students in the class = 5/20
thus, percentage of selecting a girl wearing glasses will be
= 5/20 × 100
= 5 × 5
25%
therefore,
probability will be 0.25
