if the lines shown below are perpendicular if the green line has a slope of -1/4 what is the slipped of the red line
insens350 [35]

Answer:

C; 4

Step-by-step explanation:

Mathematically, when two lines are perpendicular, the product of their slopes equal -1

in that case, we have it that;

m1 * m2 = -1

where m1 is the slope of the first line and m2 is the slope of the second line

Hence,

m2* -1/4 = -1

-m2/4 = -1

-m2 = -4

m2 = 4

Romashka [77]

Answer:

0.0975 or 9.75%

P = 0.15*(1-0.35)\\P=0.0975

The probability of exactly one engine failure is 0.0975 or 9.75%
