Place the part (amount going to the left field), over the total amount of homerun:
(a) 2/57 is your probability
(b) Divide 2/57
2/57 = 0.035, or 3.5%
YES, it is unusual for this player to hit a home run to left field, for he only has a 3.5% chance.
hope this helps
Answer: the service charge per hour for premium services is $5.5
the service charge per hour for regular services is $3
Step-by-step explanation:
Let x represent the service charge per hour for premium services.
Let y represent the service charge per hour for regular services.
One customer was charged $38 after spending 2 h in premium areas and 9 regular hours. It means that
2x + 9y = 38- - - - - - - - - - - 1
Another customer spent 3 h in premium areas and 6 regular hours and was charged $34.50. It means that
3x + 6y = 34.5- - - - - - - - - - -2
We would eliminate x by multiplying equation 1 by 3 and equation 2 by 2. It becomes
6x + 27y = 114
6x + 12y = 69
Subtracting, it becomes
15y = 45
y = 45/15
y = 3
Substituting y = 3 into equation 1, it becomes
2x + 9 × 3 = 38
2x + 27 = 38
2x = 38 - 27 = 11
x = 11/2 = 5.5
90 for the first one
120 for the second one
<span>6x + 10 = 4x -8
6x-4x = -8 - 10
2x = -18
x = -9
