The probability that one of the children will be a boy is 75%. This is because if the other 3 children were girls, there is no longer a 50% chance there will be a girl. The more girls, the lower the probability.
Answer:
What is the length of CD and what's the ratio?
F(x) = x^2 + 2x -1
Domain all real number
Range: all real numbers equal or greater than -2.
To find the range you need to find the vertex of the parabole, which is (-1,-2) and use the fact that, given that the coefficient of x^2 is positive, the funcion open upwards (which means that the vertex is a global minimum).
To find the vertex you use the quadratic formula to find the roots and then the x-coordinate of the vertex is in the middle of the two roots.
Answer:
well, the formula is A+B=C sooo
