1 answer:
Answer:
B
Step-by-step explanation:
y = is the equation of a horizontal line, parallel to the x- axis.
A line perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 6, - 9) with x- coordinate - 6, thus
x = - 6 ← is the equation of the perpendicular line

Answer:
0.8
Step-by-step explanation:
We can solve P(A or B) by using the following:
Since we know P(A) = 0.6, P(B) = 0.3 and P(A and B) = 0.1 we obtain:
