This is equal to the probability that no light fail. Probability of one light not failing = 0.98.
P(no light fails) = 0.98^20 = 0.67 or 67% to nearest percent.
You would want to add all of the angles together to find the sum. Set this equal to 360.
2x-9 + 2x-9 + x + x + x = 360
Combine like terms,
7x-18 = 360
Add 18 to both sides,
7x = 378
Divvied both sides by 7,
x = 54
The answer is 8 miles bc 48 divided by 6 equals 8
Yes because if you give them common denominators, then 7/10 stays the same and 1/2 turns into 5/10 so yes, it is larger.
