= 11x
= 13x
= 45x
= 16x + 8y
= 21x + 35y
= 11x
Step-by-step explanation:
Option → C
29 + 29 + 13 = 71
The range of possible times in seconds for x is 28:30 - 29:29. Similarly for y.
The range of possible times for z is 12:30 - 13:29
The range of possible values for x + y + z = 69:30 - 72:27 which is 178 seconds long
To be recorded as 72 minutes the sum would be in the range 71:30 - 72:27 which is 58 seconds long
P(result recorded as 72 min) = 58/178
If you simply used the ranges [28.5, 29.5) [28.5, 29.5) and [12.5, 13.5)
then the sum would be in the range [69.5, 72.5)
and P(result recorded as 72 min) = 60 seconds / 180 seconds = 1/3
Using discrete times in seconds gives a slightly different answer but is also much harder to understand.
<span>Simplifying
5x + -2 = 58
Reorder the terms:
-2 + 5x = 58
Solving
-2 + 5x = 58
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + 5x = 58 + 2
Combine like terms: -2 + 2 = 0
0 + 5x = 58 + 2
5x = 58 + 2
Combine like terms: 58 + 2 = 60
5x = 60
Divide each side by '5'.
x = 12
Simplifying
x = 12
