When you multiply the equation out and you simplify like terms you get.
2x^2 + 6xy + 4y^2
After first stop the number of passengers is :52 -y +4second stop: (52 -y +4) - (52 -y +4) * (1/3) + 4 = 25
so we have to solve : (52 -y +4) - (52 -y +4) * (1/3) + 4 = 25 at the second stop there was (52 -y +4) passengersand you have been told that 1/3 of them get offso we have to subtract (52 -y +4) * (1/3)
Answer:
30 because you have two choices with the same probability
Step-by-step explanation:
Answer:
The mean increases and the median changes to 4.
Step-by-step explanation:
To find the mean. You need to add all of the numbers together then divide by how many numbers there are. The median is found by the middle number.
X = 33/8 and -3
Use the formula with a = 6, b = -7 and c = -75
