1 answer:

3 0

The line to find: y = mx + b
the line perpendicular to y= 2/5x+6/6 so it has the slope m × 2/5 = -1
thus the slope m = -5/2
the line passes through the point (-2,6) so:
6 = (-5/2)×(-2) + b so b = 1

the equation of the line is y = -5/2x +1

Answer:

c)"At least 1 O+" is equivalent to "not none O+" (forgive the incorrect English).

P(not none O+)+P(none O+)=1

P(not none O+)=1-P(none O+)

P(not none O+)=1-0.00491

P(at least 1 O+)=0.995
