<u>Equation Solving</u>
We are given the equation:
It's required to solve it for a.
Swap sides to have the letter on the left side:
Divide by

Answer:
E = \frac{25M}{L}
Step-by-step explanation:
To solve this, we can multiple each side by E and then divide each side by L:
A family has 8 girls and 4 boys. A total of 3 children must be chosen to speak on the behalf of the family at a local benefit. What is the probability that no girls and 3 boys will be chosen?
D. 1/55.<span />
Answer:
P ( 3, - pi/3 + 2 pi n) or P ( -3 , -pi/3 + pi(2 n +1))
Step-by-step explanation:
P ( 3, - pi/3)
We can circle 2pi n around the circle and be back at the same polar coordinate
P ( 3, - pi/3 + 2 pi n)
or we can flip the radius to a negative and add pi to the theta
P ( -3, - pi/3 + pi)
Then we can circle 2pi n around the circle and be back at the same polar coordinate
P ( -3 , -pi/3 + 2 pi n +pi)
P ( -3 , -pi/3 + pi(2 n +1))
