Answer:
Option B
Step-by-step explanation:
Total Probability = 1
Probability of passing = 0.77
Probability of failing = 1-0.77
=> 0.23
A-10.0 in
B-35 in
w = (12p - 7) / 2
p = (2w + 7) / 12
12p = 2w + 7
2w = 12p - 7
3:5
because
36:60
divide by 6
6:10
divide by 2
Square root of 65 units.
Length of the other leg = sqrt(9^2 -4^2) (By Pythagoras),
= sqrt(81-16)
= sqrt65
