Answer:
5/24 or 20.8%
Step-by-step explanation:
Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2
Probability that the 8th grader is a boy = 5/(5+7) = 5/12
Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%

Given that,
The length of a wire, L = 48 m
Current in the wire, I = 18 A (west to east)
The magnetic field in the wire, B = 
(towards south)
The magnetic force acting on the wire is given by :
Using right hand rule, the direction of magnetic force is upwards.
Answer:
The solution is (x,y)=(-4,-1)
Step-by-step explanation: Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
